摘要

高电压富镍(Ni)层状氧化物基锂金属电池(LMBs)具有超高的能量密度,在先进电池领域展现出巨大的潜力。然而,在考虑循环寿命的实际应用之前,仍有必要解决循环和热稳定性差的难题。在众多改进策略中,电极电解质界面的机械和化学稳定性在应对这些挑战方面发挥着关键作用。因此,人们一直在努力解决电极-电解质界面的难题。本研究综述了富镍正极、金属锂正极和电解质的失效机理,并总结了稳定电极-电解质界面的最新突破。最后,提出了富镍锂电池面临的挑战和未来的研究方向。

Research progress in failure mechanisms and electrolyte modification of high-voltage nickel-rich layered oxide-based lithium metal batteries

High-voltage nickel (Ni)-rich layered oxide-based lithium metal batteries (LMBs) exhibit a great potential in advanced batteries due to the ultra-high energy density. However, it is still necessary to deal with the challenges in poor cyclic and thermal stability before realizing practical application where cycling life is considered. Among many improved strategies, mechanical and chemical stability for the electrode electrolyte interface plays a key role in addressing these challenges. Therefore, extensive effort has been made to address the challenges of electrode-electrolyte interface. In this progress, the failure mechanism of Ni-rich cathode, lithium metal anode and electrolytes are reviewed, and the latest breakthrough in stabilizing electrode-electrolyte interface is also summarized. Finally, the challenges and future research directions of Ni-rich LMBs are put forward.
