Next Generation Rechargeable Lithium Batteries and Beyond
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 most significant technical barrier to developing commercially viable Plug-in Hybrid Electric Vehicles (PHEV) is the energy storage system. 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 talk, we will disclose several strategies to increase significantly the energy density of lithium battery trough the development of high energy cathode material coupled with high voltage electrolyte. We also describe some new approach of improving the cycle life of Si/carbon composite anode and addressing the poor initial efficiency of this system by developing a novel prelithiation concept. We will conclude by showing a novel Sulfur selenium based system that overcome both conductivity, and dissolution issues known to sulfur system.
