The localized reaction heterogeneity of the sulfur cathode and the uneven Li deposition on the Li anode are intractable issues for lithium–sulfur (Li–S) batteries under practical operation. Despite impressive progress in separately optimizing the sulfur cathode or Li anode, a comprehensive understanding of the highly coupled relationship between the cathode and anode is still lacking. In this work,...
Lithium cobalt oxide (LCO) is widely used in Li‐ion batteries due to its high volumetric energy density, which is generally charged to 4.3 V. Lifting the cut‐off voltage of LCO from 4.3 V to 4.7 V will increase the specific capacity from 150 to 230 mAh g‐1 with a significant improvement of 53%. However, LCO suffers serious problems of H1‐3/O1 phase transformation, unstable interface between cathode...
