Electric vehicles using lithium-ion battery pack(s) for propulsion have recently attracted a great deal of interest. The large-scale practical application of battery electric vehicles may not be realized unless lithium-ion batteries with self-charging suppliers will be developed. Solar cells offer an attractive option for directly photo-charging lithium-ion batteries. Here we demonstrate the us...

Lithium ion batteries are among the most used rechargeable batteries in the world. Carbon nanostructures including carbon nanotubes (CNTs) are considered as important electrode materials for this kind of batteries. Therefore improving the performance of these carbon based electrodes in Lithium ion batteries is an important issue and attracts much attention in the battery community. In this manu...

Lithium-ion batteries (LIBs) account for the majority of energy storage devices due to their long service life, high density, environmentally friendly, and other characteristics. Although cathode materials LIB led by LiFePO 4 (LFP), LiCoO 2 (LCO), LiNi x Co y Mn 1-x-y O (NCM) occupy market share at present, demand LiMn (LMO) battery is also increasing year in recent years. With rising price var...

Nickel-based layered oxides offer an attractive platform for the development of energy-dense cobalt-free cathodes lithium-ion batteries but suffer from degradation via oxygen gas release during electrochemical cycling. While such has previously been characterized phenomenologically with experiments, atomic-scale understanding reactions that take place at cathode surface lacking. Here, we discus...

Lithium ion batteries are encountering ever-growing demand for further increases in energy density. Li-rich layered oxides are considered a feasible solution to meet this demand because their specific capacities often surpass 200 mAh g-1 due to the additional lithium occupation in the transition metal layers. However, this lithium arrangement, in turn, triggers cation mixing with the transition...

Two-dimensional (2D) nanoscale oxides have attracted research interest owing to their electronic, magnetic optical and catalytic properties. If they could be manufactured on a large scale, 2D oxides would be attractive for applications ranging from electronics to energy conversion and storage. Herein, we report facile fabrication of oxide nanosheets by rapid thermal annealing of corresponding h...
