In other to enable 40 miles PHEVs and long electric drive range EVs, there is a need of developing advanced battery systems that offer at least 250 to 300 Wh/kg energy density. The challenge is to develop batteries that are able to perform the requirements imposed by a PHEV system and yet meet market expectations in terms of cost and life. In this case, the PHEV battery will experience both deep discharge, like an electric vehicle, and shallow cycling necessary to maintain the battery for power assist in charge sustaining HEV mode. Conventional lithium-ion batteries based on metal oxides and graphite have made significant progress in recent years for HEV applications, however, durability with the PHEV duty cycle and the ultimate cost and safety of the technology remain key challenges. To achieve a very high all electric drive range, a new battery system with advanced high capacity cathode materials and stabilized high capacity anode is needed. In this paper, we will disclose several strategies to increase significantly the energy density of lithium battery trough the development of high energy and continuous gradient cathode material or composite layered-layered oxide cathode coupled with high voltage electrolyte. We will also describe some new approach of improving the cycle life of Si/carbon composite anode by impregnating nano-silicon particles within graphene sheets or making a new composite system.
