正极辊压工艺的研究

A Research of the craftwork of roller-pressing positive plate

引俄辊压设备的进粒系统对正极活性物质的流动性及形态均有较高的要求。本文通过对引俄辊压设备的进料系统进行理论分析后,改进了进料系统,降低了正极辊压设备对活性物质的流动性及形态的要求。改进后的辊压设备不必使用特殊处理的活性物质就能辊压正电极,从而降低了生产成本。经测试,使用传统工艺生产的正极活性物质,即可满足生产批量化,压制出厚度、重量均匀性较高的正电极。

This article talks about the process of how to reduce the requirement of the Russian roller-pressing machine＇s feeding system for the fluidity and conformation of positive materials.On the basis of analyzing the feeding system,we improved the structure. It＇s unnecessary for the improved structure to roller-press positive plates with specially produced positive material,so the producing cost reduced.The experiment data shows that the improved structure is able to produce positive plates with high consistency of ply and weight to meet the needs of production in batches.
