Next Generation Rechargeable Lithium Batteries and Beyond
Abstract
To enable 40 miles Plug-in Hybrid Electric Vehicles (PHEVs) and long electric drive range Electric Vehicles (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 PHEVs 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 meeting market expectations in terms of cost and battery 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 Hybrid Electric Vehicle (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 lecture, the speaker will disclose several strategies to increase significantly the energy density of lithium battery through the development of high energy cathode material coupled with high voltage electrolyte. He will also describe some new approaches of improving the life cycle of Si/carbon composite anode and addressing the poor initial efficiency of this system by developing a novel prelithiation concept. He will conclude by showing a new superoxide air battery and a novel lithium air closed system as well as a novel Sulfur selenium based system that overcome both conductivity, swelling and dissolution issues known to sulfur system.
