Publication number: 20240109116Abstract: A method of forming a shell of a soft pack battery is provided. The method includes steps of adjusting temperature of a thin sheet material for the shell to a working temperature, applying a difference of fluid pressure to the thin sheet material as forming pressure, and a two-stage forming step. In a first-stage preforming step, a preform with a first depth is formed by the thin sheet material and at least one compensation portion is formed on the preform. In a second-stage final-forming step, the perform is molded into the final formed part with a second depth. Thereby the shell with a higher depth-thickness ratio is manufactured and the thin sheet material is uniformly deformed. The compensation portion is used for compensation of deformation at corners of the bottom of the final molded part. Thus thinning rate is less than 30% and yield rate is increased.Type: ApplicationFiled: October 3, 2022Publication date: April 4, 2024Inventor: Chin-Han Wang
