硅由于其高比容量，被广泛认为是下一代锂离子电池最有前途的负极材料之一。在过去的十年中，各种纳米结构被成功地证明可以解决与粉碎和固体-电解质界面相相关的可逆硅阳极的主要挑战。然而，由于纳米材料的使用，电化学性能仍然受到限制。在本进展报告中，重点介绍了锂离子电池硅阳极的发展面临的挑战和最新进展，包括初始库仑效率、面容量和材料成本，这些都需要进一步的研究，为硅阳极在未来锂离子电池中的广泛应用提供了光明的前景。
Silicon, because of its high specific capacity, is intensively pursued as one of the most promising anode material for next-generation lithium-ion batteries. In the past decade, various nanostructures are successfully demonstrated to address major challenges for reversible Si anodes related to pulverization and solid-electrolyte interphase. However, the electrochemical performance is still limited by challenges that stem from the use of nanomaterials. In this progress report, the focus is on the challenges and recent progress in the development of Si anodes for lithium-ion battery, including initial Coulombic efficiency, areal capacity, and material cost, which call for more research effort and provide a bright prospect for the widespread applications of silicon anodes in the future lithium-ion batteries.
