Science Daily  May 23, 2023 As potential alternatives to Li-ion batteries, rechargeable Ca metal batteries offer advantageous features such as high energy density, cost-effectiveness, and natural elemental abundance. However, Ca metal passivation by electrolytes and a lack of cathode materials with efficient Ca2+ storage capabilities, impede the development of practical Ca metal batteries. To overcome these limitations, an international team of researchers (Japan, USA – Toyota Research Institute of North America) verified the applicability of a CuS cathode in Ca metal batteries and its electrochemical properties. Their results showed that a CuS cathode comprising nanoparticles that are well dispersed in […]
