Hard Case vs. Soft Case Lithium Polymer Batteries (2025 Guide)
Design and Manufacturing Characteristics of Soft-Case Batteries Soft-case batteries, as opposed to the two types of hard-case batteries, cylindrical and square, also known as soft-case lithium batteries, are essentially liquid lithium-ion batteries encapsulated in a polymer case. Structurally, soft-case batteries are packaged in aluminum-plastic film, which usually contains a three-layer structure: - Outer protective
