摘要
Lithium-ion batteries produced from water-based manufacturing processes are favored for their environmental and economic advantages, while currently sacrificing some technical performance. This paper reports an integrated study on the calendering process of water-based manufacturing of lithium-ion battery graphite electrode, aiming to improve electrochemical performance of the manufactured lithium-ion batteries. The interactive mechanism between the calendering process and the porous microstructure of the produced graphite electrode was systematically investigated. It reveals that the graphite electrode with 40 % of porosity produced under 79,509 N/m calendering force achieves an optimal 333 mAh/g of specific capacity and 91.2 % of capacity retention after 100 cycles.
