Strategies of Inhibiting Anode Dendrite Growth in Lithium-sulfur Batteries
Recently, lithium-sulfur batteries have attracted wide attention due to their highly theoretical specific capacity (1673 mAh g-1) and high energy density (2800 Wh kg-1), which is regarded as the most promising next generation energy used for portable electronic devices, vehicles and energy storage system. However, there are still some problems existed in the practical application of lithium-sulfur batteries, particularly, the problems caused by the growth of lithium dendrite seriously hinder the real application and development of lithium-sulfur batteries. In this paper, we summarize the strategies of lithium anode improvement in recent years, and introduce them in sufficient progressive order from three aspects, including anode surface modification, anode modification and anode structure design. Nevertheless, the growth of lithium dendrite is still a thorny problem, and we have to keep going to devote time and energy towards addressing it.
