ALEXANDRIA, Va., Oct. 21 -- United States Patent no. 12,770,930, issued on Oct. 20, was assigned to ZHUHAI COSMX BATTERY Co. LTD. (Zhuhai, China).

"Lithium-ion battery configured to reduce housing extrusion effect caused by negative electrode swelling" was invented by Xiaodong Cao (Zhuhai, China), Fei He (Zhuhai, China) and Suli Li (Zhuhai, China).

According to the abstract* released by the U.S. Patent & Trademark Office: "The disclosure provides a lithium-ion battery that satisfies the equation (2M+3)2(S+2)2/Wless than=20, where M=exp(m1/d1)+(d1-2)(m1-0.26). Wherein, m1 is the tensile strength of the negative electrode current collector in the length direction, and d1 is the thickness of the negative electrode current collector. Addition...
