Abstract
This paper presents a systematic analysis of the key material properties and optimization strategies of current collectors in both all-sol-id-state lithium batteries(ASSLBs)and conventional lithium-ion batteries.The study reveals that current collectors not only serve as essential components for electron transport but also play a crucial role in enhancing energy density,cycling stability,and interfacial compatibility.Com-monly used current collector materials include transition metals(such as copper and aluminum),carbon-based materials(such as graphene),lithium alloys,and emerging two-dimensional materials(such as MXene),each exhibiting distinct advantages and limitations in terms of conduc-tivity,chemical stability,and structural compatibility.Optimization strategies primarily focus on surface modification and geometric design to im-prove electrical conductivity,corrosion resistance,interfacial stability,and lithium nucleation behavior.In ASSLBs,the unique physicochemical properties of solid-state electrolytes pose additional challenges and opportunities for the design of current collectors,particularly regarding interfa-cial contact and ionic conductivity.With continuous advancement in material selection and structural design,current collectors are expected to significantly enhance the energy density,safety,and long-term stability of next-generation lithium batteries.关键词
