Nb-doped and Al₂O₃ + B₂O₃-coated granular secondary LiMn₂O₄ particles as cathode materials for lithium-ion batteries

Abstract

Nb-doped and Al2O3 + B2O3-coated granular secondary LMO particles enabling superior cycling performance at 25 and 55 °C.

A nano-truncated Ni/La doped manganese spinel material for high rate performance and long cycle life lithium-ion batteries

“…9a, including ohmic resistance from the electrolyte ( R s ), charge transfer resistance ( R ct ), Warburg impedance ( W 0 ) and double layer capacitance (CPE). 49 In general, the Nyquist plot is composed by two semicircles (high and medium frequency) and an inclined line at low frequency. The high frequency semicircle is associated with the SEI layer of the cathode materials.…”
