8. Handling of Cells
Because this product uses a soft-package LIP/LiFePO4 pouch cell, the source document emphasizes careful handling of the aluminum laminated package, tabs, and short-circuit protection.
| Topic | English Summary from Source |
|---|---|
| Package Film | The soft aluminum foil package can be damaged by sharp parts such as pins, needles, and Ni-tabs. Sealed edges may be damaged by heat above 100°C or by bending/folding. |
| Short Circuit Prevention | Never short-circuit the cell. The source requires appropriate PCM circuitry to protect against accidental pack short circuit. |
| Mechanical Shock | LIP cells have lower mechanical endurance than metal-can LIB cells; falling, hitting, and bending may degrade characteristics. |
| Tab Handling | Tabs, especially aluminum tabs, should not be bent unnecessarily. |
9. Notice for Designing Battery Pack
The source provides design guidance for pack toughness, cell fixing, internal clearance, tab connection, and leakage-related mishaps. These notes are important for OEM enclosure and PCB integration.
| Topic | English Summary from Source |
|---|---|
| Pack Toughness | The battery pack should have sufficient strength to protect the LIP cell from mechanical shocks. |
| Cell Fixing | The LIP cell should be fixed by its larger surface area; no cell movement should be allowed inside the pack. |
| Inside Design | The inside of the pack should not include sharp-edge components near the LIP cell. |
| Tab Connection | Ultrasonic welding or spot welding is recommended. If manual soldering is used, the soldering iron should be temperature controlled and ESD safe; soldering temperature should not exceed 350°C; soldering time should not exceed 3s; soldering should not exceed 5 times; direct heating of the cell body is prohibited. |
| Mishap Design | The pack should be designed to avoid heat generation even if leakage occurs. The PCM should be isolated from electrolyte as much as possible and narrow spacing between bare patterns at different voltages should be avoided. |
10. Assembly, Use, Warranty, and Storage Notes
The final PDF sections cover assembly restrictions, cell connection, internal short-circuit prevention, disassembly prohibition, fire/liquid prohibition, replacement responsibility, warranty, battery storage, and chemical-aging notes.
| Topic | English Summary from Source |
|---|---|
| Battery Pack Assembly | Crushing the PCB, shocks, high temperature, and contact with sharp-edge components are not allowed during assembly. |
| Cell Connection | Direct soldering of wire leads or devices to the cell is prohibited; lead tabs with pre-soldered wiring should be spot welded to the cells. |
| Internal Short Circuit Prevention | Enough insulation layers should be used between wiring and cells so that the pack structure prevents internal short circuit. |
| Disassembly Prohibition | Cells must not be disassembled because disassembly may cause internal short circuit, gassing, fire, explosion, or other hazards. |
| Fire and Liquid Prohibition | Cells must not be disposed of in fire and must not be immersed in water, seawater, drinks, or other liquids. |
| Replacement and Damaged Cells | Battery replacement should be done only by the cell supplier or device supplier. Damaged, deformed, leaking, or abnormal cells should not be used. |
| Warranty Period | The source states a one-year warranty from shipment for defects proven to be due to manufacturing process rather than customer abuse or misuse. |
| Storage of Batteries | Batteries should be stored at room temperature with about 30-50% capacity. The source recommends charging about once every half year to prevent over-discharge. |
| Other Chemical Reaction | Battery performance deteriorates over time because batteries use chemical reactions. Life may shorten if charge, discharge, ambient temperature, or other operating conditions are outside specified ranges. |
11. Application Fit and OEM/ODM Supply Notes
