Biomass materials have attracted extensive attention in functional composites because of the unique mi-crostructure, renewability and electrochemical performance. Herein, porous NiO/C composites were synthesized through a hydrothermal reaction and calcination using cellulose-rich natural cotton as carbon source. The BET specific surface area of NiO...

Silicon is regarded as one of the most important high-capacity materials and has been added to some commercial anodes to increase the specific energy of lithium-ion batteries (LIBs). However, the large volume change of Si during cycling leads to cracking, continuous accumulation of solid electrolyte interphase (SEI), and electric disconnection, pos...

Lithium-rich layered oxides (LLOs) are considered as the most promising candidate for the cathode of high energy density lithium-ion batteries. However, the poor cycle stability especially under high temperature is hindering its practical applications. Herein, a full concentration gradient LLO with spinel modification is designed and prepared. This...
