With the increasing demand for high energy density and rapid charging performance, Li-rich materials have been the up and coming cathodes for next-generation lithium-ion batteries. However, because of oxygen evolution and structural instability, the commercialization of Li-rich materials is extremely retarded by their poor electrochemical performan...

Li-rich layered materials that have Co-free and Mn-rich 3d-transition metals have the potential to increase the achievable energy density of batteries because they are inexpensive and yield high capacity by exploiting an additional oxygen redox reaction. However, these have low electrochemical activity and sustainability, with severe voltage fade, ...

With the increasing demand for energy, layered lithium-rich manganese-based (Li-rich Mn-based) materials have attracted extensive attention because of their high capacity and high voltage. However, the Li-rich Mn-based materials suffer from a series of problems of oxygen release, transition metal (TM) migration, and structural transformation, which...

Transition-metal sulfides are key cathode materials for thermal batteries used in military applications. However, it is still a big challenge to prepare sulfides with good electronic conductivity and thermal stability. Herein, we rapidly synthesized a Co-doped NiS2 micro/nanostructure using a hydrothermal method. We found that the specific capacity...

To meet the growing demand for global electrical energy storage, high-energy-density electrode materials are required for Li-ion batteries. To overcome the limit of the theoretical energy density in conventional electrode materials based solely on the transition metal redox reaction, the oxygen redox reaction in electrode materials has become an es...

Li‐rich oxides have garnered intense interest recently for their excellent capacity in rechargeable lithium‐ion batteries (LIBs). However, poor cycling stability and capacity degradation during the cycling process impede their practical application. Herein, two ball‐shaped cobalt‐free oxide materials, Li1.1Mg0.05Ni0.3Mn0.55O2 and Li1.1Zn0.05Ni0.3Mn...
