Abstract

2차 전지의 극판용 활물질 지지체에 있어서, 지지체의 중앙부위는 외곽부보다 큰 개공률을 가지도록 하고, 양쪽 모서리 부분을 중앙 부위보다 개공률을 작게 가지도록 설정하여 홀을 형성하므로써, 고용량 전지에 사용가능하고, 지지체의 제조 공정에서 모서리 부위의 뒤틀림을 방지하고, 전극에서의 활물질량을 증가시켜 단위부피당 전극 용량을 높일 수 잇는 2차 전지 및 극판 활물질 지지체 제조 방법을 제공할 수 있다.In the active material support for a pole plate of a secondary battery, the center portion of the support has a larger porosity than the outer portion, and both corner portions are set to have a smaller porosity than the center portion to form holes. It is possible to provide a method for manufacturing a secondary battery and a cathode plate active material support which can be used and prevents warping of corner portions in the support manufacturing process and increases the amount of the active material in the electrode to increase the electrode capacity per unit volume.
