Amorphous metal oxides as the negative electrode for lithium-ion batteries

Abstract : The commercialized electrode materials for lithium-ion batteries are limited to a few highly crystalline ones (for instance, graphite and LiCoO2). Due to the highly crystalline nature of these materials, the Li+ storage sites are confined only to the […]
