Abstract: Lithium ion secondary batteries are described that have high total energy, energy density and specific discharge capacity upon cycling at room temperature and at a moderate discharge rate. The improved batteries are based on high loading of positive electrode materials with high energy capacity. This capability is accomplished through the development of positive electrode active materials with very high specific energy capacity that can be loaded at high density into electrodes without sacrificing performance. The high loading of the positive electrode materials in the batteries are facilitated through using a polymer binder that has an average molecular weight higher than 800,000 atomic mass unit.
