摘要

水基制造工艺生产的锂离子电池因其环保和经济优势而备受青睐，但目前也牺牲了一些技术性能。本文综合研究了水基制造锂离子电池石墨电极的压延工艺，旨在提高所制造锂离子电池的电化学性能。系统研究了压延工艺与所制石墨电极多孔微结构之间的相互作用机理。结果表明，在 79,509 牛/米的压延力下生产的石墨电极孔隙率为 40%，在 100 次循环后，比容量达到 333 mAh/g，容量保持率达到 91.2%。

An integrated simulation and experimental study of calendering process in water-based manufacturing of lithium-ion battery graphite electrode

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.

期刊介绍： The aim of the Journal of Manufacturing Processes (JMP) is to exchange current and future directions of manufacturing processes research, development and implementation, and to publish archival scholarly literature with a view to advancing state-of-the-art manufacturing processes and encouraging innovation for developing new and efficient processes. The journal will also publish from other research communities for rapid communication of innovative new concepts. Special-topic issues on emerging technologies and invited papers will also be published.
