文摘
- •
SDM is investigated as an electrolyte additive for LiNi0.5Mn1.5O4 cathodes.
- •
The cycling performance is enhanced with appropriate amount addition of SDM.
- •
The surface layer derived from SDM on the cathode is more stable and robust.
- •
Dissolution of Mn and Ni of LiNi0.5Mn1.5O4 can be mitigated by adding SDM.
