Carbon-Coated Single-Crystal LIMn2O4 Nanoparticle Clusters as Cathode Material for High-Energy and High-Power Lithium-Ion Batteries

摘要

Lithium-ion batteries (LIBs) are expected to fulfill the rate capability and capacity requirements for a range of applications, from mobile devices to electric vehicles (EVs)/hybrid electric vehicles (HEVs) and even energy storage systems (ESSs). Conventional LIBs are unsuitable for applications with high-power requirements such as EVs and HEVs, as they exhibit low rate capability, especially during the charging process (that is, the batteries require a long time to charge). For EVs to become popular, battery charging should be completed in a few minutes, that is, in a comparable time to that required for filling automobiles with gasoline.
