cathode material

Michigan-headquartered lithium-ion battery maker A123 Systems has sold its Chinese cathode materials manufacturing facility to chemicals company Johnson Matthey.

A123 Systems retained the ownership of its intellectual property and will maintain its research and development capability of battery materials and to further develop improvements of its lithium iron phosphate (LFP) formulation.

The US Advanced Battery Consortium LLC (USABC) has awarded $7.7m to California-based Envia Systems for an electric vehicle (EV) battery technology project.

The three-year project is focused on the development of high-energy lithium-ion layered-layered cathode and silicon-based anode material for EV applications. The goal of the research programme is to develop an energy storage system that supports the commercialisation of hybrid, plug-in hybrid, electric and fuel cell vehicles.

The global developer of chemicals, materials and energy storage solutions, 3M, has teamed up with Korea-based ECOPRO to develop a patent license to build upon existing work in nickel-manganese-cobalt (NMC) for cathode materials for lithium-ion batteries.

Under the license agreement, 3M is granting a license for use of three patented cathodes it holds. These patents are US6964828, US7078128, US8241791 and all global equivalents that relate to preparing compositions useful as cathodes for lithium-ion batteries.
