Recently, there have been frequent safety accidents in battery products, and consumers are increasingly demanding the electrical performance and safety of lithium-ion batteries. Battery manufacturers, as well as regulatory authorities and industry associations in various countries, are paying more attention to the safety performance testing of lithium-ion batteries. Improving the safety performance testing level of lithium-ion batteries is a trend

Batteries can be divided into three categories: 1. Chemical battery primary batteries, secondary batteries (lead-acid batteries, nickel chromium batteries, nickel hydrogen batteries, lithium-ion batteries), fuel cells 2. Physical battery solar cells, double-layer electrical capacitors, thermal batteries 3. Biological battery enzyme hydrolysis batteries Lithium Battery (abbreviated as LB), also known as Lithium Primary Battery, Lithium Secondary Battery (also known as Rechargeable LB), With the increasing capacity, the safety of lithium batteries is also receiving increasing attention. These main lithium battery standards have been examined from different perspectives for their safety and electrical performance, and are now classified as follows. From the table, it can be seen that currently various standards for lithium batteries mainly examine the safety and electrical performance of lithium batteries from three perspectives: 1. battery safety performance 2. environmental adaptability 3. electrical performance

Different standards have different focuses on battery testing: IEC61960 mainly focuses on the electrical performance testing of lithium batteries; IEC62133 and JISC8714 in Japan require a focus on product usage safety and environmental adaptability safety; GB/T18287 not only includes some safety testing items, but also includes performance testing; UL2054 and UL1642 comprehensively examine the safety of cells and batteries in various usage environments, including fault conditions, heavy pressure conditions, and combustion conditions
