This work reports the performance of LiNi_0.4Co_0.2Mn_0.4O₂ electrodes employing sodium carboxymethyl cellulose as the binder (CMC/NCM). Compared with conventional organic PVDF-based electrodes, the CMC/NCM electrodes display very uniform distribution of NCM and carbon particles together with strong adhesion among the particles and with the current collector, leading to significantly mitigated crack formation and delamination of the electrode upon repeated delithiation/lithiation processes. Additionally, these electrodes offer enhanced Li⁺ diffusion kinetics, reduced polarization, therefore, excellent high C-rate capability, and extremely stable cycling performance even at elevated temperature (60 °C). Benefiting from the features of low cost, environmentally friendliness, and easy disposability-recyclability, the water-soluble CMC is a promising binder for practical application in energy storage systems.

这项工作报告了使用羧甲基纤维素钠作为粘合剂（CMC / NCM）的LiNi _0.4 Co _0.2 Mn _0.4 O ₂电极的性能。与传统的基于有机PVDF的电极相比，CMC / NCM电极显示NCM和碳颗粒分布非常均匀，并且颗粒之间以及与集电器之间具有很强的附着力，从而大大减轻了电极在反复脱锂时的裂纹形成和分层/锂化过程。此外，这些电极提供增强的Li ⁺因此，即使在高温（60°C）下，它也具有良好的扩散动力学，降低的极化作用，出色的高C速率能力以及极其稳定的循环性能。受益于低成本，环境友好和易处理性-可回收性的特点，水溶性CMC是有希望在储能系统中实际应用的粘合剂。
