Lithium Polymer Battery Handling Guidelines
Soft Aluminum Foil Protection
- Easily damaged by sharp edge parts such as pins, needles, and Ni-tabs compared to metal-can-cased LIB
- Do not strike lithium polymer battery with any sharp edge parts
- Trim nails or wear gloves before handling lipo batteries
- Clean worktable to ensure no sharp particles are present
- Sealed edge may be damaged by heat above 100°C, bending, or folding
Prohibition of Short Circuit
- Never create short pack circuit - generates high current causing heating, electrolyte leakage, gassing, or explosion
- LIP tabs may be easily short-circuited by placing on conductive surfaces
- External short circuits may lead to heat generation and cell damage
Mechanical Shock Prevention
- LIP cells have less mechanical endurance than metal-can-cased LIB
- Falling, hitting, bending, etc. may cause degradation of LIP characteristics
