Materials firm Umicore has agreed a third patent deal to acquire US technology firm 3M’s lithium-ion cathode IP.
Sumitomo Chemical is to quadruple production of its lithium-ion secondary battery separators and become a majority stake-holder in a cathode firm.
Separator production capacity will be raised in a ‘stepwise manner’, with the initial expanded commercial-scale production coming on stream in August 2017.
Two heavy weight chemical firms are in negotiations to collaborate on cathode active materials (CAM) for lithium-ion batteries in the North America market.
Japan’s TODA KOGYO CORP and Germany’s BASF have entered into exclusive negotiations with the goal of manufacturing a range of CAM for the automotive, consumer electronics and stationary storage markets.
Canadian metals company American Manganese has started proof of concept testing of its large-scale lithium-ion cathode material recycling process.
Research and development firm Kemetco Research will undertake tests of the company’s proprietary hydrometallurgical process for the recycling of cathode materials, specifically lithium–cobalt.
Dexmet has introduced new microgrid anode and cathode foil materials down to 25 micron (.001”) in both aluminum and copper at widths up to 305mm (12”).
These thinner materials produce very small openings in the material, and should prove to be the perfect anode and cathode electrode solution for improved overall cell performance.
Nanotech company NEI Corporation (NEI) and atomic layer deposition specialist (ALD) PneumatiCoat Technologies (PCT) have agreed to jointly develop ALD-coated battery materials.
The agreement includes the development, production and marketing of cathodes, anodes and solid electrolytes for lithium-ion batteries. The companies will offer ALD coatings on a variety of battery material compositions, such as mixed metal oxides phosphates, silicates, titanates, sulfides, graphite and silicon-based active materials.
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.
