Physical problems and developments of lithium ion batteries

As a new type of rechargeable battery, the lithium ion battery has been or will be widely applied in many fields such as cellular telephones, laptop computers and electric vehicles. However, the physical problems related to lithium ion batteries are sometimes ignored, one of which is how to enhance the bulk electronic conductivity of the cathode material without adding any electrically conducting substance such as carbon black. In this paper we will describe, for the most part, recent developments with respect to the physical problems of lithium ion batteries.
