Since its introduction, lithium batteries have quickly become a leader in the field of batteries due to their excellent performance. However, due to a series of problems in battery production, the quality of battery products in the market is uneven, and the later cycle life of battery capacity often fails to reach the designed service life, affecting user experience. With the gradual expansion of application scope and the increasing volume energy density and capacity of individual batteries.

The testing standards for lithium batteries are mainly examined from three perspectives, namely:

1. Safety performance of battery use

2. Environmental adaptability

3. Electrical performance

Therefore, in order to adapt to the further development of China's lithium battery industry, improving the production technology level of lithium batteries, researching and producing lithium battery manufacturing equipment with independent intellectual property rights have become requirements for the further development of enterprises in the industry. In recent years, with the rapid growth of market demand in the lithium battery industry, lithium battery manufacturers have expanded their production capacity on a large scale. A group of lithium battery automation production equipment manufacturers with strong research and development and manufacturing capabilities have emerged in China

In fact, the reason why lithium batteries have problems is closely related to their unique production process.

1. The structure of a battery includes components such as a casing, upper cover, plates, separators, busbars, poles, bridge protection plates, terminals, etc.

2. The production process of lithium batteries can be divided into three stages: front-end electrode manufacturing, back-end cell packaging, and back-end battery activation. The purpose of the battery activation stage is to fully activate the active substances and electrolyte in the battery to achieve stable electrochemical performance. The activation stage includes pre charging, formation, aging, and constant capacity stages. The purpose of pre charging and chemical conversion is to activate the positive and negative electrode materials through the first few cycles of charging and discharging, so that the materials are in their optimal state of use.

If internal defects caused by the manufacturing process or other issues of lithium batteries lead to a series of safety hazards such as explosions, it is not worth the loss. Therefore, testing the production process of lithium batteries has become a top priority.

For different battery systems, targeted tests need to be conducted based on material properties and lithium battery characteristics, such as ternary positive/graphite negative lithium batteries, lithium iron phosphate positive/graphite negative lithium batteries, or lithium titanate negative lithium batteries. The vast majority of lithium batteries are packaged in steel shells, making it difficult to detect internal quality issues using conventional methods. At this point, the role of X-ray detection equipment becomes apparent.
