Carbon Conductive Additive for Lithium Ion Batteries

摘要

Provided is a lithium ion battery containing a negative electrode, a positive electrode, and an electrolytic solution containing an imide anionic lithium salt and LiPO ₂ F ₂ . The positive electrode contains positive electrode active material particles and a carbon conductive additive that forms an island bridge structure on the surface of the positive electrode active material particles. Carbon conductive additives include graphene that is partially covered by the surface of the positive electrode active material particles to form an island structure, carbon black that adheres to the surface of graphene, and carbon nanotubes that connect the graphenes as a bridge structure.
