METHOD AND APPARATUS FOR MANUFACTURING ELECTRODE FOR LITHIUM-ION SECONDARY BATTERY AND ELECTRODE FOR LITHIUM-ION SECONDARY BATTERY

摘要

Coating liquid (L) including a silicon-based active material is coated on an anodic current collector (11), and an anode active material layer having a line-and-space structure composed of stripe-shaped active material patterns (121) including a plurality of separated lines is formed. At an anode formed thereby, the expanding direction of the active material during charge can be controlled, and capacity decline induced by damage to the patterns or peeling of the patterns can be inhibited owing to absorption by pores between the stripe-shaped active material patterns (121).
