Here, a new spherical Li1.23Mn0.46Ni0.246Co0.046Al0.015O2 (0.6Li2MnO3·0.4LiNi0.8Co0.15Al0.05O2, LMNCA) cathode with low cobalt content is rationally designed and prepared. The lithium deficiencies engineering with different lithium (from 75% to 103% of theoretically stoichiometric ratio...

Traditional carbonate-based electrolytes are not suitable for high voltage lithium metal batteries (LMBs), which seriously hinders the development of high-energy density LMBs. Here, a novel flame retardant fluorine-rich electrolyte (termed FFT) composed of 1.2 M lithium hexafluorophosphate (LiPF...

Here, a natural and non-toxic inositol additive with six hydroxyl groups is added into the 2 M ZnSO4 aqueous baseline electrolyte to enhance the electrochemical performances of the zinc ion batteries (ZIBs). 2H chemical shift in the Nuclear magnetic resonance demonstrates that the inositol...
