Problems solved by technology

This can lead to reduced reliability of batteries fitted with such electrodes
In order to avoid this defect, it is necessary to arrange an additional resin layer or film etc. under the electrodes, which creates problems
[0007] In addition, since the metal mold has a fixed size and shape, only one type of electrode with a fixed size and shape can be produced using one metal mold
Thus, in cases where the size and shape of electrodes must be changed even slightly in accordance with changes in customer needs or market conditions, all equipment used to make electrodes must be replaced

Abstract

This invention relates to a method of manufacturing an electrode for a secondary battery, which enables cost savings and the manufacture of products having various sizes and shapes. The method includes (A) preparing an electrode plate, (B) cutting the electrode plate to conform to the width of the electrode, thus providing a unit electrode plate, and (C) removing at least one of the corner regionsof the unit electrode plate.

Description

technical field [0001] The present invention relates to a method of making battery electrodes, and more particularly to a method of making battery electrodes, which is cost-effective and enables the manufacture of products of various sizes and shapes. Background technique [0002] Generally, a chemical battery refers to a battery that uses a chemical reaction composed of a positive electrode, a negative electrode, and an electrolyte to generate electrical energy. It is divided into a disposable primary battery and a reusable battery that can be charged and discharged. Due to the advantage of the rechargeable and dischargeable characteristics of the secondary battery, its application is gradually increasing. [0003] Among storage batteries, lithium storage batteries have high energy density per unit weight and are therefore widely used as power sources for electronic communication devices and high-power hybrid vehicles. [0004] The lithium storage battery includes an elect...
