Fish paper is an electrical insulation material commonly used in lithium-ion and LiFePO4 battery pack assembly. It is used to provide insulation, separation, and added protection between battery cells and conductive components.
Fish paper is widely used in both cylindrical and prismatic battery builds, making it a practical material for custom battery packs, repairs, and general pack assembly work.
Common Uses for Fish Paper
✔ Cell Insulation – Helps isolate battery cells and conductive surfaces ✔ Pack Separation – Used between cells and structural components ✔ Battery Pack Assembly – Common in custom lithium-ion and LiFePO4 builds ✔ Repair & Maintenance – Useful for replacing worn or damaged insulation
Applications
✔ Lithium-Ion Battery Packs – Used in 18650, 21700, and other cylindrical cell builds ✔ LiFePO4 Battery Systems – Supports prismatic cell pack assembly ✔ DIY Battery Projects – A common material in custom battery construction ✔ Battery Repairs – Helps restore insulation in existing packs
Why Use Fish Paper
Fish paper is valued for its durability, insulating properties, and versatility in battery pack construction. It is commonly used anywhere additional insulation and separation are needed within a battery assembly.
Important Note
Battery pack assembly requires proper tools, materials, and safety practices. Always ensure fish paper is used appropriately for your battery design and application.
