Aluminum-ion batteries are faster, cheaper, and safer than lithium-ion batteries, but finding an appropriate material for the cathode is proving to be a barrier to commercialization. Researchers in Poland investigated the potential of carbon–tungsten oxide composites as cathode materials.
Read MoreLithium iron phosphate is a widely used cobalt-free cathode material for lithium-ion batteries. It is known to experience certain kinds of defects in its crystal structure, however, and a recent study led by researchers at the Skolkovo Institute of Science and Technology explores the existence of hydroxyl groups in phosphorus vacancies.
