Abstract Scope |
The advent of portable electronics and electric vehicles has precipitated an increase in demand for lithium-ion batteries (LIB) with accelerated charging capabilities. However, the charging and discharging speed of the LIB is limited by the limitation of internal diffusion of the active material and the resistance between the electrolyte and the electrode. To this end, the surface of the anode active material (LCO, NCM, etc.) was modified with a silane coupling agent, which is a low-cost polymer material that serves to reduce the interfacial resistance. Furthermore, a ferroelectric material was coated on the surface of the anode active material with the objective of improving the internal diffusion of the active material. As a result of this, the interfacial resistance and rate-rate characteristics were enhanced. |
