硅碳负极的功能化调控策略研究进展
Advances in functionalization strategies for silicon-carbon anodes
摘要
Abstract
Silicon/carbon composite(Si/C)anodes,offering a theoretical capacity ten times superior to graphite and an optimal operating potential,have emerged as a pivotal solution for improving the energy density of conventional lithium-ion batteries.However,their commercial implementation confronts three fundamental constraints:structural degradation from huge volume variation(～300%)during cycling,inherently poor electrical conductivity restricting rate capability,and continuous reconstruction of the solid-electrolyte interphase(SEI)accompanied by irreversible lithium consumption.To solve the above-mentioned issues,advanced functionalization strategies have been devel-oped,including heteroatom doping(e.g.,nitrogen,phosphorus,boron),polymer coating(constructing conductive networks and artificial SEI),and three-dimensional conductive network construction.Many studies confirm the supe-rior synergistic effects of multi-strategy integration over individual modification approaches.Future research priori-ties should encompass multi-scale interfacial engineering,interface compatibility for solid-state battery systems,and sustainable manufacturing processes.The synergistic advancement of materials science and engineering is instrumen-tal in accelerating the commercialization of next-generation high-energy-density batteries.关键词
