【摘要】 金属锂是下一代高能量密度二次电池的理想负极材料。但锂具有高的反应活性和还原性,造成其SEI膜不稳定、锂枝晶生长和体积膨胀效应等问题,从而限制了锂金属电池的实际应用。基于锂负极存在的问题,综述了锂负极、隔膜、人工SEI膜、电解液和固体电解质的改性策略,并对其未来的研究方向进行了展望。更多还原

【Abstract】 Lithium is considered as an ideal anode material for the next generation high energy density secondary batteries. However, lithium has high reactive activity and reductivity, causing its SEI film instability, lithium dendritic growth and volume expansion effect, thus limiting its practical application in lithium metal batteries. To resolve the above problems, modification strategies for lithium metal anode have been developed. The recent advances in lithium anode, separator, artificial SEI film, electrolyte and solid electrolyte are reviewed in this paper. And the future research is proposed.更多还原
