The use of thicker electrodes can contribute to a reduction in cell costs. However, the properties of the electrode must be kept in view to be able to meet the performance requirements. Herein, the possibility of simultaneous multilayer slot die coating is investigated to improve the electrode properties of medium‐ and high‐capacity anodes. The stable coating window of the two‐layer slot die coating process is investigated to produce property‐graded multilayer electrodes. Electrodes with different styrene–butadiene rubber (SBR) gradients are investigated with regard to adhesive force and electrochemical performance. An increase in the adhesive force of up to 43.5% and an increase in the discharge capacity is observed.

改进的高能锂离子电池组件渐变阳极同时两层槽模涂层的原位研究

使用较厚的电极可有助于降低电池成本。但是，必须注意电极的性能，才能满足性能要求。在此，研究了同时进行多层缝口模头涂覆的可能性，以改善中容量和高容量阳极的电极性能。研究了两层狭缝模头涂覆工艺的稳定涂覆窗口，以生产性能分级的多层电极。研究了具有不同丁苯橡胶（SBR）梯度的电极的粘合力和电化学性能。观察到粘合力增加至43.5％，放电容量增加。
