2. 1. Advanced Materials for Rechargeable Lithium Batteries

   Author : Jae-Kwang Kim; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rechargeable lithium battery; rate capability; Organic electrode; cycle stability.; Ionic liquid-based polymer electrolyte; electrochemical stability;

   Abstract : Lithium rechargeable batteries have gained much attention in the pursuit for alternative energy sources because of advantages such as high energy density and high electric potential. In addition, the development of low-cost materials has been of interest to reduce the cost of batteries, especially those destined for transportation applications such as electric (EVs) or hybrid-electric vehicles (HEVs).
