ZnO/CNFs锂硫电池隔膜的制备及其 电化学性能研究.

Using carbon nanofibers （CNFs） network structure to fix three-dimensional acicular zinc oxide （ZnO） whiskers, thereby preparing an intermediate layer of ZnO/CNFs, and through the tortuous pore channels of the intermediate layer, the shuttle path of lithium polysulfide is prolonged, so that it can Stably inhibits the "shuttle effect" of lithium-sulfur batteries through chemical adsorption and physical adsorption. Characterization results such as charge-discharge test and cycle test show that the initial discharge capacity of the battery reaches 1458 mAh·g-1 at a current density of 0.1 C, The coulombic efficiency remains at 99.4%;at a current density of 0.5 C, the initial discharge capacity can still reach 1113 mAh·g-1,and after 300 cycles of charge and discharge, the discharge capacity remains at 734 mAh·g-1.
