[Lithium Battery Safety Evaluation] We conduct cell destruction tests and puncture tests.
"Our lab cannot conduct puncture tests that pose a fire risk." "I want to confirm the safety limits of the cell pack under development." We will carry out the rigorous tests that are unavoidable in the development and adoption of lithium-ion batteries on your behalf. Our company offers contracted services for safety tests that involve destruction, such as the "puncture test" that penetrates with a steel nail, as well as tests for crush and external short circuits. "We can't afford to request tests from a full-fledged testing institution." We respond to such concerns.

basic information
■Contents of the Response - Needle Penetration Test Specification of penetration speed and position is possible. Real-time measurement of surface temperature and voltage behavior. - Crush Test The cell is crushed under a certain load or displacement to evaluate behavior during internal short circuits. - Environmental Monitoring Video recording during the test and time analysis leading to thermal runaway. ■Flow from Request to Report Preliminary Meeting: Determine test conditions (nail diameter, speed, fully charged state, etc.). Sample Submission: Send the test cell or pack to our testing center. Test Implementation: Conduct the test based on the plan in a safe environment. Data Submission: Deliver a test report including temperature and voltage graphs, images, and videos.

Applications/Examples of results
- Selection and comparative evaluation of new suppliers - To verify the "safety margins" that do not appear on the specification sheets according to our own standards when adopting overseas manufacturers or new business partners. - Verification of safety design in product development - As evidence to confirm whether the design of the enclosure will not affect the surroundings (i.e., whether it will not catch fire) in the event of any physical damage. - Creation of data for customer submission - Acquisition of supporting data for the "safety test report" submitted to end users and public institutions.
