Rational design of dual-ion doped cobalt-free Li-rich cathode materials for enhanced cycle stability of lithium-ion pouch cell batteries.

The synergistic effect of single-crystal structure and dual doping in Li-rich cobalt-free cathode materials was thoroughly investigated. Lithium-ion pouch cells employing Sb/Sn doped LiMnNiO and graphite exhibited a specific capacity of 191.01 mA h g at 1C rate and exceptionally stable performance upon cycling, with capacity retention of 87.
