无负极锂金属电池的挑战与发展
Challenges and development of anode-free lithium metal battery
摘要
Abstract
Anode-free lithium metal battery has become an academic hotspot due to its high theoreti-cal capacity,energy density and low cost. However,due to the lithium-sparse property of copper foil and the high activity of lithium metal,the lithium deposition/stripping is not uniform,resulting in many problems such as lithium dendrites and excessive lithium consumption,which limits the practi-cal application. In this paper,the advantages,challenges and solutions of anode-free lithium metal batteries were comprehensively reviewed. Four improvement strategies were discussed in detail,in-cluding modifying the current collector,constructing a stable solid electrolyte interface(SEI) film,in-troducing lithium supplementation technology and optimizing the electrolyte. The mechanism of the negative side affecting the deposition/stripping of lithium metal,the advantages of the positive side additional lithium source and the influence of the electrolyte on the reversibility of the anode-free lithium metal battery were discussed. The advantages and disadvantages of the four strategies and the future development direction were summarized.关键词
