Separators are becoming increasingly important in both academic research and industrial production as a means of enhancing the performance of lithium‐ion batteries (LIBs), particularly at a high rate. However, fast charge–discharge processes will produce local heat accumulation, which accelerates the local reaction rate of Li+ to form lithium dendrites. Commercial polyolefin separators fail to tackle...
Solid‐state lithium batteries have become the focus of the next‐generation high‐safety lithium batteries due to their dimensional, thermal, and electrochemical stability. Thus, the progress of solid electrolytes with satisfactory comprehensive performances has become the key to promoting the development of solid batteries. Herein, poly(vinylidene fluoride) (PVDF) solid polymer electrolytes (SPEs) possess...
Lithium‐ion batteries (LIBs) are promising energy storage devices for integrating renewable resources and high power applications, owing to their high energy density, light weight, high flexibility, slow self‐discharge rate, high rate charging capability, and long battery life. LIBs work efficiently at ambient temperatures, however, at high‐temperatures, they cause serious issues due to the thermal...
As anodes of Li‐ion batteries, copper oxides (CuO) have a high theoretical specific capacity (674 mA h g−1) but own poor cyclic stability owing to the large volume expansion and low conductivity in charges/discharges. Incorporating reduced graphene oxide (rGO) into CuO anodes with conventional methods fails to build robust interaction between rGO and CuO to efficiently improve the overall anode performance...
In article number 1702667, Jie Xiong, Weidong He, and co‐workers synthesize high‐performance Cu2O/CuO/rGO through a facile single‐step hydrothermal method and employ it as an anode of a lithium‐ion battery, delivering remarkable energy capacity, rate capacity and thermal stability. In the cover, the two “magic” hands represent the 3D hierarchical network of rGO. The robust “magic” network mitigates...
