Lithium-ion batteries are widely used in portable electronics and electric vehicles due to their high energy density, stable cycle life, and low self-discharge. However, irreversible lithium loss during the formation of the solid electrolyte interface greatly impairs energy density and cyclability. To compensate for the lithium loss, introducing an external lithium source, that is, a prelithiation agent, is an effective strategy to solve the above problems. Compared with other prelithiation strategies, cathode prelithiation is more cost-effective with simpler operation. Among various cathode prelithiation agents, we first systematically summarize the recent progress of Li₂S-based prelithiation agents, and then propose some novel strategies to tackle the current challenges. This review provides a comprehensive understanding of Li₂S-based prelithiation agents and new research directions in the future.

硫化锂：一种有前途的高性能锂离子电池预锂化剂

锂离子电池由于具有高能量密度、稳定的循环寿命和低自放电等优点，广泛应用于便携式电子产品和电动汽车。然而，固体电解质界面形成过程中不可逆的锂损失极大地损害了能量密度和循环性能。为了补偿锂损失，引入外部锂源，即预锂化剂，是解决上述问题的有效策略。与其他预锂化策略相比，阴极预锂化更具成本效益且操作更简单。_{在各种正极预锂化剂中，我们首先系统地总结了Li 2} S基预锂化剂的最新进展，然后提出了一些新的策略来应对当前的挑战。_{该综述提供了对Li 2} S基预锂化剂和未来新研究方向的全面了解。
