摘　　要：电堆是热电池中的核心部件,其制造工序由极片压制和多极片组装两道关键工序构成。大尺寸薄型极片在采用自动化压制时因其物理特性和自动化设备的需求之间存在偏差,正极材料的成型性不足,影响了正极片的成型率。研究了有机碳包覆正极材料自动压机成型的问题,通过在正极粉末颗粒表面包覆多孔粗糙的碳层,提高了正极材料的成型率,为大尺寸薄型正极片压制提供了一种方法。The battery stack is the core component of the thermal battery.Its manufacturing process consists of two key processes:electrode pressing and multi-electrode assembly.When large-sized thin electrodes are pressed automatically,there is a deviation between their physical properties and the requirement of the automation equipment.The formability of the positive electrode material is insufficient,which affects the forming rate of the positive electrode.This paper studied the problem of organic carbon-coated positive electrode materials.By coating the surface of the positive electrode powder particles with a porous and rough carbon layer,the forming rate of the positive electrode material was improved,which provides a method for pressing large-sized thin positive electrode sheets.
