Ultralong cycle life enabled by in situ growth of CoMo1-xP/Mo heterostructure for lithium-sulfur batteries
文献摘要：
Lithium-sulfur batteries(Li-S batteries)are considered as promising new-generation electrochemical energy storage devices due to their extremely high theoretical energy density(2600 Wh kg1)and the-oretical specific capacity(1675 mAh g-1).However,numerous problems such as poor conductivity and the shuttle effect during discharge-charge process limit the practical application of lithium-sulfur batter-ies.In this work,porous tubular CoMo1-xP/Mo constructed by in situ growth of metal Mo was designed as the sulfur host for lithium-sulfur batteries.The introduction of Mo modulated the electronic structure of CoMoP to improve the conductivity of cathode and facilitate the redox kinetics,as well as the CoMo1-xP/Mo heterostructure was beneficial to inhibit the shuttle effect through the interaction with lithium poly-sulfides,which improved cycling stability.As a result,CoMo1-xP/Mo/S cathode had a low-capacity decay rate of only 0.029％per cycle after 2000 cycles at 0.5 C.This work provided a new perspective for the fur-ther design of high-performance lithium-sulfur battery cathode materials.
