Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities
Abstract
Here, the authors report a graphene-silica assembly which could be coated onto a nickel-rich cathode via a scalable process for considerably improved electrochemical performance. In the presence of such graphene balls, a full cell benefits from an increased volumetric energy density by 27.6%.
