Hierarchical Carbon-Coated LiFePO_4 Nanoplate Microspheres with High Electrochemical Performance for Li-Ion Batteries

摘要

Rechargeable lithium-ion batteries (LIBs) have currently been undergoing rapid expansion due to their superior performance including long cycle life, high specific energy, and no memory effect. More importantly, there seems to be a swiftly growing interest and there is a potentially huge market for large-scale LIBs that could potentially provide electric vehicles (EVs) or hybrid electric vehicles (HEVs) with high power and high energy density. Unfortunately, the presently dominating LIBs use limitedly available and expensive cobalt components as cathode materials. Lithium iron phosphate (LiFePO_4) displays numerous appealing features to make it a promising cathode materia.
