Nickel Hydride Batteries

　　SK Innovation and U.S. Battery Company develop Nickel Hydride Batteries with twice the energy density and cycle life

　　According to foreign media reports, PolyPlus Battery Company, a private company in the United States focusing on the development of the first rechargeable lithium metal battery, announced that it will cooperate with SK Innovation (SK Lithium-ion Battery Manufacturer I), South Korea’s largest energy and chemical company, to jointly develop lithium-ion batteries. Research and development of Nickel Hydride Batteries.

　　SK Innovation will invest in the development of PolyPlus’ conductive glass separators, and the company is considering an equity investment in PolyPlus with a view to licensing its technology in the future.

　　The collaboration will focus on PolyPlus’ solid-state lithium anode laminates, which can double the energy density and cycle life of rechargeable batteries. The initial goal is to produce and test prototype batteries to demonstrate whether the added volume and weight results in improved energy density and cycle life relative to existing lithium-ion batteries.

　　SK Innovation plans to complete research on conductive glass separators by the end of 2021 and use them in the research and development of Nickel Hydride Batteries. Conductive glass separators are a key technology to promote the stability of Nickel Hydride Batteries. The company hopes the successful development of a conductive glass separator will accelerate the commercialization of Nickel Hydride Batteries.

　　PolyPlus Battery Company is headquartered in Berkeley, California, USA. The company invented and has a technology patent for protecting lithium-ion batteries and protecting lithium metal battery electrodes. This technology is sulfur lithium-ion batteries, lithium-air batteries and water lithium-ion batteries. The core technology of batteries. Scientists at PolyPlus Battery Company invented a patented process that combines lithium metal with a continuous monolithic glass electrolyte. Cell validation in the laboratory showed that the continuous monolithic glass prevents dendrites and promotes lithium metal cycling.
