Ever the innovators, 3M and LG Chem entered into a patent license agreement.

LG Chem, one of the largest lithium-ion battery supplier for electric cars, was granted by 3M a license to U.S. Patents 6,660,432, 6,964,828, 7,078,128, 8,685,565 and 8,241,791 (and all global equivalents including in Korea, Taiwan, Japan, China and Europe).

Those patents are related to nickel, cobalt, manganese (NCM) cathodes for lithium-ion batteries.

If those solutions will help to improve LG Chem cells for EVs, we are all in, although the press release doesn't reveal details about expected improvements.

"NCM cathode compositions offer an outstanding balance of power, energy, thermal stability and low cost. NCM cathode materials can be tailored through changes in composition and morphology to meet a wide range of customer requirements from high-energy handheld consumer electronics to high-power electric vehicles."

Kyunghwa Min, vice president of LG Chem IP Center commented:

“We are pleased to have reached this agreement with 3M. This license will give our battery customers confidence in LG’s technology and our long-term commitment to the battery industry. The license also opens the door to new opportunities for LG Chem as a supplier of cathode materials to the battery industry.”

Christian Milker, business manager, 3M Electronics Materials Solutions Division said:

“LG Chem is a leader in the electric vehicle battery field, and NCM cathode compositions have shown significant benefit in large format applications, like electric vehicles. This license will accelerate the adoption of NCM technology to meet the growing demand for electric vehicles worldwide.”
