TOKYO: Semiconductor Energy Laboratory Co., Ltd. (SEL), has conducted a safety demonstration test on a lithium-ion rechargeable battery that achieves both fire resistance and high energy density.

The company says it used a nail penetration test with a newly developed cathode active material – Ni-doped lithium cobalt oxide (LCNO) – developed by SEL. 

It says the lithium-ion rechargeable battery developed by SEL improved its fire resistance without compromising the high energy density characteristic of the batteries.

In a nail penetration test, one of the standard safety tests, SEL’s prototype LCNO battery did not ignite and there was no temperature rise on the cell surface. SEL says the structural stability of LCNO is crucial in achieving this performance.

According to the company, the LCNO battery has high structural stability, contributing to the suppression of deterioration during high-voltage charging and charge-discharge cycles.
