X-Ray Machine on Battery Inspection: the Complete Guide

Table of Contents

1. What is a Battery X-Ray Inspection Machine?

The well-known X-ray machine with excellent performance is widely used in electric vehicles, consumer electronics, household appliances, aviation, and other fields. 

To adapt to the continuous progress of the lithium battery industry, it is mandatory to improve the level of lithium battery production technology, product quality, and user safety. Here comes the industrial X-ray lithium-ion battery testing equipment. This equipment can inspect the internal conditions of the lithium battery. The positive and negative electrodes are different. The transmittance of materials to X-rays is also different. Hence, X-ray tests have become an important means of battery detection.

 

2. How to Test Lithium Batteries with an X-Ray Machine?

Before understanding the importance of an X-ray test in battery inspection, you first need to know how X-ray inspection works.

All X-ray inspection devices are composed of three basic features:

  • X-ray tube to generate X-ray photons
  • Operation platform to move the given sample in varied directions so that it can be inspected from all angles and magnitudes.
  • A detector located on the other side of the sample to catch and collect X-ray photons and convert them into an image.

 

X-ray imaging test works with the help of X-ray photons, which are passed through the target material kept on the operation platform. The resultant rays will be collected on the other side through a detector, which results in an image formation. Based on the differential absorption principle, the X-ray photons pass through the target object in a differential manner depending on its physical properties, such as density, atomic weight, and thickness.

Usually, heavier objects absorb more X-rays, so that they can develop into an image, whereas lighter objects are more transparent. Since different objects have unique characteristics, different amounts of X-ray photons are collected on the other end of the target object, to form a final image.

 

3. What are the Various Categories of Lithium-Ion Battery Testing by X-Ray System?

  •  2D X-ray inspection system – This system displays two-dimensional images from both sides of the sample at once and develops an image of the internal components. It can be operated online or offline.
  • 3D X-ray inspection system – It develops three-dimensional images of a given battery sample by forming a series of 2D cross-sections. It can be operated both online and offline.
  • Online X-ray inspection system – It is used for online data collection and comparison, especially for processing large quantities of samples. It comparatively runs slowly with less capacity and high cost.
  • Offline X-ray inspection system – This system can achieve sampling inspection and panel inspection. It runs quickly with high quantity and less cost. Solar panels can be detected and analyzed by x-ray machine for quality assurance. 

 

4.What are the Functions of Lithium Battery Testing X-Ray Equipment?

  • The X-ray machine is integrated with the production line to improve battery performance. Hence, automated loading or unloading of the batteries during the manufacturing stage can reduce overall manpower costs.
  • This machine can analyze the thickness of the stainless-steel weld that can encase the lithium battery. Its thickness should be adequate to prevent leakage.
  • It can verify the quality of electric connections, short circuits, misalignments, internal settings, etc., and figure out the welds, fuses, faulty assemblies, and broken cables.
  • It detects imperfections by quantifying alignments, missing materials, overhangs, linear distances, and foreign element inclusions.
  • It can analyze the failed batteries and determine the signs of voids, holes, or misalignments if any.
  • It can analyze the functionality completely and predict the probability of a short circuit.
  • X-ray instruments also check the fitting, length, and lithium sheet twist as well.

 

5. What Types of Batteries can be Inspected with an X-Ray Machine?

  • Connection type – It includes wirebond for good flexibility, tab weld for structural rigidity, and ribbon for higher currents.
  • Pack type – It includes cell/pouch, coin, cylindrical, square stacked, and roll type. Here, the X-ray system can inspect the alignment for each layer of the battery. Both these types can be assessed for bend and peel forces to ensure optimal performance and safety.
  • Weld type – X-ray system is used for inspection as there is no need for piercing of the sample during the manufacturing stage which may affect the electrochemical property due to high heat exposure.

 

6. How Much does a Battery Testing X-Ray Equipment Cost?

You get the best, affordable, and personalized cost according to your requirements.

Factors like the voltage, power, spot size, generator specifications, degree of automation, detector resolution, choice of a flat panel detector or an image intensifier, and the vicinity of the X-ray source to the sample object can have an impact on the price.

Furthermore, the closed type is comparatively more stable, less expensive, and lasts for years. Offline type is also comparatively affordable and quick that can evaluate more samples at once.

Similarly, a 3D system is more expensive than 2D since it consumes more time for high throughput inspection from both sides.

So, you basically get what you pay for.

 

7. What are the Benefits of Battery Testing X-Ray Equipment?

  • Quick, feasible, and efficient – Unlike other inspection systems like eddy current testing or ultrasonic testing, the X-ray inspection system takes quick time to assess the internal portions of the given battery sample completely and efficiently.
  • Non-destructive – X-ray inspection is a type of non-destructive testing technique that can assess the internal parts of the given battery sample without altering the sample integrity.
  • Inspect parts of varied sizes and materials – Lithium battery structure consists of a bridge protection plate, clapboard, bus bar, upper cover, terminal, shell, plate, etc. This is where an X-ray system can easily inspect its internal structure of varied types and sizes.
  • Internal part analysis – X-ray system evaluates the internal parts of the given battery sample for electric connections, short circuits, interconnects, misalignments, internal settings, etc. and figure out the welds, fuses, faulty assemblies, broken cables, overhangs, concentricity, linear distances, and foreign element inclusions along with quantification.
  • Determine failure pre-production – The X-ray system can analyze the batteries and determine the signs of voids, if any, to prevent failure before the production stage. It also checks the thickness of stainless steel that covers the given battery to avoid any leakage.
  • Confirm part authenticity and credibility – X-ray system checks the fitting, length, and lithium sheet twist. Furthermore, it can analyze the functionality completely and predict the probability of a short circuit.

 

8. How to Use Lithium Battery Testing X-Ray Inspection Equipment?

  1. Keep the sample battery cells manually in the carrier.
  2. Open the front door and place the carrier with the sample battery in the testing station.
  3. Detect from the first corner position using an X-ray system and note down the detection results.
  4. Rotate the detection table so that the second corner position coincides with the first corner position.
  5. From the second corner, note down the detection results.
  6. The C-arm rises one layer, cycles the above action, and detects the two corners of the other layers of the core.
  7. The associated software analyzes the test results, after which the batteries are qualified as good or bad quality.

 

9. How to Choose the Right Battery Testing X-Ray Equipment?

  • Tube voltage – Always, opt for the low voltage (say 90kV). It’s because the higher voltage (say 140kV) has a greater penetration level comparatively which may affect the contrast effect of the image.
  • Image quality – Image quality can be affected by the factors such as spot size, voltage, power, detector resolution, a field of view, and the vicinity of the X-ray source to the sample object. Hence, we recommend you select typical assemblies and develop an X-ray system. Rather than the technical competence, image quality is more connected with the inspection setup.
  • Stage type – Opt for the stage type depending on the workspace and sample size. Remember that large or multiple small samples require a large stage size.
  • Data storage – If you are dealing with manufacturing multiple batteries, it is better to opt for the online X-ray machine with more storage space so that you can store the results for a long time.
  • Reliability and warranty – A good quality X-ray machine supplied by a reliable manufacturer should have a warranty for a minimum of one year where the repairs and component changes are done for free.
  • Ease of use – In modern X-ray systems, automation of inspection involves only pass/fail criteria. Furthermore, you can interpret the final X-ray images due to the use of varied colors. However, the inspector should have good knowledge of battery production. He should be able to understand the application of contrast and voltage settings.
  • Maintenance cost – Maintenance cost depends on the selection of 2D/3D type, open or closed tube, online/offline, standard/high-definition flat panel detectors. However, do check for the system failure modes, power supplies, cables, or connectors annually.

 

10. How Should We Maintain the Lithium Battery Testing X-Ray Inspection Equipment Properly?

  • Check if the safety induction switch and emergency stop switch are working properly
  • Check the condition of the power switch and cables as well
  • Verify if the rotation axis of the X-ray machine is working properly. Make sure if the movement of each axis is smooth, normal, and not loose. Even if there is any rust formation, apply grease and check the movement
  • Perform tube cleaning regularly
  • Perform functional verification and check if there is any unusual noise.
  • Conduct mechanical, electrical, and safety testing. Make sure there is no sign of damage on the inner and the outer side of the X-ray instrument
  • Check for the presence of scratches in the observation window glass. Make sure to change it if there is any scratch
  • Inspect the fans and clean all the filters using cotton

 

FAQs on X-Ray Machine for Battery Inspection

 

Lithium-ion batteries may fail in every stage of its life cycle due to manufacturing faults, bad usage, or degradation.

 

Causes of failure during the manufacturing stage:

  • Mechanical deformation
  • Inclusion of water or air
  • Damage of layers or the separator
  • Welding defects
  • Defects in liquid or gas tightness
  • Particle contamination
  • Divergent filling level

 

Causes of failure due to bad usage:

  • Mechanical – internal short-circuit due to the presence of dendrites or particles
  • Electrical – overcharging may lead to increase in temperature, gas formation, and adverse reactions
  • Thermal – Exposure to flame

 

Causes of failure due to degradation:

  • Lithium plating
  • Reformation of solid electrolyte interface
  • Contamination or migration of reaction products
  • Gassing
  • Corrosion

non-destructive testing at regular intervals in every stage can successfully prevent those above-listed damages.

 

 

The more the utility of lithium batteries, the more will be the consequences of failure. Hence, it is advised to follow strict quality control standards to ensure safety.

 

As already mentioned above, even a tiny imperfection may turn out to be life-threatening. Hence a high-resolution inspection is recommended for the conventional verification of any complete battery cells. Such high-level online imaging can be achieved by the combination of microfocus X-ray imaging with quick and advanced sharp contrast digital imaging devices. Especially high-performance battery cells as well as energy conversion devices may turn out to be critical in the case of any defect, as it may have severe consequences on safety and performance.

 

 

There are varied aspects in detecting of lithium batteries:

  • Checking the imperfection by measuring missing material, foreign material inclusions, and overhangs
  • The performance of the battery can be enhanced by correlating it with the microstructure and design.
  • Analysis of the failed battery cells through visual interpretation
  • Usually, lithium sheets are rolled together to create a battery. Using CT (computed tomography) based X-ray machine, it is possible to determine any nick as well as check its length, twist, and fitting.
  • Identify any sign of voids, holes, or the presence of any misalignment in the stacked parts.
  • Detect insulation layer, faulty assemblies, fuses, welds, broken cables, etc.
  • Measures the internal structure, linear distances, and alignments precisely
  • Check if the lithium battery is fully functional
  • Predicts if there is any chance of short circuit

  • Focal spot size – The smaller the focal spot size, the smaller will be the geometric shadow of the sample with improved spatial resolution, and the image will be sharper.
  • Acquisition geometry – Acquisition geometric factors that affect the image quality include a source to image receptor distance, magnification, orientation, and focal spot size. Changes in these factors bring variations in the magnification of anatomic structure.
  • Beam energy – For imaging a specific part, suitable energy is required to optimize the dose and contrast. Using higher energy can cause more X-ray penetration at a lesser dose and lesser contrast. Conversely, lesser beam energy leads to higher contrast where more X-ray dose is required to penetrate and form an image.
  • Tube current – It determines the total photons impinging the sample to create an image. The more the tube current, the more will be the sample dose and noise reduction. The exposure time should be in seconds. Longer exposure time will affect special resolution causing image blur.
  • Magnification – The more magnification, the more will be the ability to inspect the intricate flaws in a sample precisely.
  • Collimation – It refers to the confinement of the X-ray beam upon the sample area. Hence, there will be a decrease in scattered radiation, less radiation exposure, and improvement in signal-to-noise ratio (SNR), image contrast, and noise.
  • Detector performance – It depends on the detector resolution, detector element size, and SNR. The smaller the detector element size with greater spatial frequency, the more will be the resolution.
  • Anti-scatter grid – Using an anti-scatter grid can enhance the image quality by limiting the scattered rays.
  • Image processing – If image processing is not done, digital images will have very low contrast. In image processing, the contrast can be adjusted to improve visual perception, edge enhancement, noise reduction, and grayscale processing. Thus, it is possible to alter the pixel values and optimize the contrast.
