CHEMICAL PRE-INTERCALATION APPROACHES FOR IMPROVED ELECTROCHEMICAL PERFORMANCE OF EMERGING ENERGY STORAGE ELECTRODES

摘要

Renewable energy storage solutions, including advanced Li-ion batteries (LIBs) and emerging systems, such as beyond-Li ion batteries and pseudocapacitors, require new materials with high energy density, rapid charge transfer and stable behavior over extended cycling. Materials with layered crystal structures have proven themselves among the most reliable electrode materials, exhibiting high performance in these emerging energy systems. However, improvement of ion storage capability and cycling stability of these materials is needed and can be achieved through chemical modification of layered materials prior to electrochemical cycling.
