Lithium manganese oxide is regarded as a capable cathode material for lithium-ion batteries, but it suffers from relative low conductivity, dissolution in electrolyte and structural distortion cubic to tetragonal during elevated temperature tests. This review covers comprehensive study about the main directions taken into consideration supress drawbacks of lithium oxide: structure doping surfac...
DOI: 10.1002/aenm.201600922 considering the overpotential during charge process. Recently, Yamada et al. reported that LiNi0.5Mn1.5O4 can only reversibly provide capacity of ≈75 mA h g−1 in the more concentrated hydrate melt electrolytes (≈30 mol kg−1), which is 50% of theoretical capacity.[14] The oxygen evolution side reaction also largely significantly reduce the coulombic efficiency. In add...
Lithium-ion batteries (LIBs) suffer from charging difficulties, capacity decay, and severe ageing in a low-temperature environment. In this work, we suggest theoretical study strategy for improving the resistance of LiMn2O4(LMO) pouch cells, by introducing photothermal conversion layer composed copper single-walled carbon nanotubes. A three-dimensional electrochemical–thermal coupling model lit...
