摘要

本研究系统评估了水性黏结剂聚丙烯酸(PAA)与不同种类丁苯橡胶(SBR)的配伍对锂离子电池性能的影响，通过固定PAA含量并变换SBR种类，分析了其对负极特性和全电池电化学性能的作用，并进一步探讨了提升PAA含量对电极及电芯性能的影响规律。结果表明，锂化SBR(SBR-Li)与PAA结合能协同实现低电极阻抗与优良的电解液润湿性。电性能测试显示，采用小粒径、高模量的SBR-Li可降低电芯的交流内阻(ACR)与直流内阻(DCR)，使1 C充电恒流比提升2.4%，并在25℃下循环500周后容量保持率提高约1%。然而，当PAA含量增加0.5%时，电芯阻抗增大，倍率性能有所弱化，但循环膨胀率降低了0.5%。研究表明，锂化SBR与PAA的配伍可针对性调控硅基电池体系的性能，为硅基材料中的黏结剂选型提供了重要依据。

Abstract

This study systematically evaluates the impact of combining the water-based binder polyacrylic acid (PAA) with different types of styrene-butadiene rubber (SBR) on lithium-ion battery performance. By keeping PAA content constant while varying SBR type

this study analyzes their effects on anode characteristics and full-cell electrochemical performance

and further investigates the performance evolution of electrodes and cells with increasing PAA content. Results indicate that the combination of lithiated SBR (SBR-Li) and PAA synergistically achieves low electrode impedance and excellent electrolyte wettability. Electrochemical tests demonstrate that small-particle

high-modulus SBR-Li reduces the cell AC impedance and DC internal resistance

increases the constant current ratio during 1 C charging by 2.4%

and improves capacity retention by about 1% after 500 cycles at 25℃. However

increasing PAA content by 0.5% raises cell impedance and reduces rate capability

although the cycle swelling rate decreases by 0.5%. This study demonstrates that the formulation of lithiated SBR and PAA can selectively tune the performance of silicon-based battery systems

providing crucial guidance for binder selection in silicon-based material applications.
