Two Chinese companies have signed an international raw materials supply chain deal aimed at creating “one of the most technologically-advanced lithium battery cathode material manufacturers” in the country.
BCL, a wholly-owned subsidiary of Hong Kong-based investments firm Burwill, agreed the deal with Chinese lithium battery materials provider Hunan Changyuan Lico on 9 February.
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.
