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.
These patented cathode compositions of nickel, manganese and cobalt offer balance of power, energy, thermal stability (which is especially important for safety of large format batteries) and low cost. The materials can be tailored to application requirements.
Dong-Che Lee, CEO of ECOPRO said: “The compositions can be particularly beneficial in emerging applications for lithium-ion batteries in the transportation and grid energy storage markets.”
The use of the patented cathode compositions by ECOPRO will advance NMC’s use in lithium-ion batteries and offer more choices to manufacturers.
