摘要
En 中文
The research and development of high-performance lithium-ion batteries is essential to promote the upgrading and development of industries for and electric vehicles and energy storage power station. At present, the mainstream graphite anode active material has almost released its theoretical capacity (372 mAh g- 1 ). Silicon- based anode materials possess higher theoretical specific capacity (up to 4200 mAh g- 1 ), relatively low discharge voltage platform (lithium potential about 0.4 V), abundance non-toxic and so on, regarded as the most promising anode materials for next-generation lithium-ion batteries. However, the practical application of silicon-based anodes is hampered by some tricky challenges, such as dramatic volume changes due to lithium insertion/ extraction, low conductivity and coulombic efficiency, fast capacity decay. Introducing silicon-based anode materials to enhance battery energy density is an inevitable trend in the development of lithium-ion batteries, and optimizing and improving silicon-based anode binders is a very effective and promising way to solve the problems existing in silicon-based active materials. This paper presents a comprehensive literature review, focusing on the research progress and application of binders in silicon anodes. It offers valuable insights into the future trajectory of this burgeoning field.
