摘　　要：石墨和炭黑颗粒因为都是表面疏水性、非极性,没有添加剂其在水中发生聚集不能分散。石墨负极在制浆过程中,CMC和SBR的对石墨颗粒的分散以及对浆料的微观结构形成非常重要,CMC和SBR太多或者太少都会影响电池性能。对SBR连接机理、SBR对石墨分散的影响、SBR相关的黏辊、锂电干燥温度对SBR的影响、SBR对锂离子电池低温性能的影响以及负极膨胀的影响进行了分析阐述,强调在石墨负极应用中SBR优化对锂离子电池的重要性。Graphite and carbon black particles cannot be dispersed due to their non-polarity and surface hydrophobic properties. Too many or too few CMC and SBR in battery production have a negative impact on electrode performance. CMC and SBR are very important for the dispersion of graphite particles and the microstructure formation of the slurry. The influence of SBR on the decentralized and dispersive effect of SBR in graphite,the influence of SBR on the low temperature performance and negative expansion of lithium-ion battery,emphasizes the importance of SBR optimization to lithium-ion battery in application.
