Handling Precautions and Guidelines for High Discharge Rate Lithium-Polymer Secondary Batteries and Cells
1 - Charging
1.1 Charging Current
Charging current cannot exceed the rapid charge current specified in Section 4.6. Charging at currents exceeding this value could lead to the generation of excessive heat and cell leakage, which poses safety hazards.
1.2 Charging Voltage
Charging voltage shall not exceed the charge voltage specified in Section 4.3. Charging beyond the maximum safe voltage is strictly prohibited. The charging device used must be designed to comply with this condition. It is extremely dangerous to charge to a voltage exceeding, that which is lead to excessive heat generation and cell leakage posing safety hazards.
1.3 Charging Temperature
The battery or cell shall be charged within the temperature range specified in Section 4.14. Charging outside of the specified range may cause damage to the battery or cell, which could lead to excessive heat generation and cell leakage posing safety hazards.
1.4 Charging Polarity
Charging of a battery or cell under the condition of reverse polarity is strictly prohibited. The wiring polarity for each battery or cell must confirmed prior to connection to any device. Charging of the battery under the condition of reverse polarity may lead to the generation of excessive heat and cell leakage, which poses safety hazards.
2 - Discharging
2.1 Discharging Current
Discharging current shall not exceed the maximum discharge current discharge current specified in Section 4.7. Discharging a battery or cell beyond the specified values may cause damage to the battery or cell, including significant loss of discharge capacity, excessive heat generation, and cell leakage, which poses safety hazards.
2.2 Discharging Temperature
Discharge temperature shall not fall outside of the range specified in section 4.14. Discharging of a battery or cell outside the specified range may cause damage to the battery or cell including significant loss of discharge capacity, excessive heat generation, and cell leakage, which poses safety hazards.
Discharge voltage shall at no point fall beneath the discharge cut-off voltage value specified in Section 4.5. Discharging of a battery or cell beyond this value may causes loss of cell performance, characteristics, and function. It should be noted that the self-discharge characteristics of a battery or cell may cause an over-discharged state if not used for extended periods of time
Any devices which the battery or cell may be connected to that acts as a load (active or passive), shall be equipped with a device to prevent discharge exceeding the cut-off voltage specified in Section 4.5.
In order to prevent over-discharging, the battery or cell shall be charged periodically to maintain between 3.7V and 3.9V per cell. In the event of any individual cell voltage dropping below 3V, the charge device shall have function to stop further charging and display the battery or cell is in an abnormal state.
Charging devices should also be equipped with function or a device to control the voltage while recharging to prevent the battery or cell voltage from exceeding the value specified in Section 4.3.
3 - Storage
3.1 The storage temperature for a battery or cell shall not fall outside of the range specified in section 4.15. Storage of a battery or cell outside of the specified range may cause damage to the battery or cell including significant loss of discharge capacity and cell leakage, which poses safety hazards.
4 - Short Circuit
4.1 Never short-circuit a battery or cell. Doing so generates an extremely high current, which causes heating of the cells and leads to electrolyte leakage, gassing and even explosion. The tabs of a cell may be easily short-circuited when brought into contact with a conductive surface. Appropriate circuitry with PCM (Protection Circuit Module) shall be employed to protect against accidental short circuit of a battery or cell(s).
5 - Mechanical Shock
5.1 Impacts to or bending of a battery or cell may cause degradation of the battery or cell characteristics.
6 - Notices of Battery Design
Battery shall have sufficient strength and the cell(s) within a batterty shall be protected from mechanical shocks.
6.2 Cell Fixing
Cells shall be fixed as a battery pack by the largest surface area. No cell 10.2.1 movement in the battery shall be allowed.
6.3 Battery Internal Design
No sharp edge components shall be contained inside the battery containing a cell or cells.
6.4 Tab Connection
Ultrasonic welding is the preferred method for cell tab connection. Battery and/or cell shall be designed in such a way that shear force is not applied to the cell tabs.
6.5 Damaging Forces
Battery and/or cell shall be designed in such a way that heat is not generated in the event of cell leakage caused by damaging outside forces.
(i) Isolate PCM (Protection Circuit Module) from leaked electrolyte.
(ii) Avoid narrow spacing between bare circuit patterns with different voltage, including and not limited to around the terminating connector.
(iii) Battery or cell shall not come into contact with liquid from electrolyte. In the case of leaked electrolyte touching bare circuit patterns, higher potential terminal material may dissolve and precipitate at the lower potential terminal causing short circuit. The design of the PCM (Protection Circuit Module) shall mitigate these risks.
7 - Notices for Assembly of a Battery
7.1 Shock, high temperature, and contact with sharp edge components shall not be allowed during the battery assembly process.
7.2 Direct soldering of the cell tabs and close proximity to heated tools such as a soldering iron is strictly prohibited. Temperatures exceeding 80°C may cause damage and degrade cell performance.
7.3 During battery assembly, ultrasonic welding power must be kept to a minimum to prevent damage to cell(s) and electronic circuits where present.
7.4 Cell Connection
7.4.1 Direct soldering of wire leads or devices to the tabs of a cell is strictly prohibited.
7.4.2 Lead tabs with pre-soldered wiring shall be spot welded to the cells. Direct soldering may cause damage to cell components, such as separator and insulator, by heat generation.
7.5 Prevention of Short Circuit within a Battery
7.5.1 Insulating layers between wiring or cells shall be sufficient enough to maintain safety against short circuit.
7.6 Electrolyte Warning
7.6.1 Construction of a battery or cell shall be such that there is no liquid from the electrolyte flowing. However, in the case of the electrolyte coming in contact with skin or eyes, immediately flush the affected areas with fresh water and consult a physician.
8 - Notice for Disassembly of Batteries and Cells
8.1 Never disassemble a battery or cell(s). Disassembly may lead to internal short-circuit within a cell or cells, which may lead to fire or explosion of the battery or cell.
9 - General Warnings
9.1 Incineration Warning
Never incinerate or dispose of a battery or cell(s) in fire. Doing so may cause explosion of the battery or cell(s).
9.2 Submersion Warning
Batteries and cells shall never be submerged or soaked with liquids such as water, seawater, or any other liquid for any reason.
9.3 Battery Cell Replacement Warning
Never attempt to replace a battery cell. Disassembly may lead to internal short circuit within a cell or cells, which may lead to fire or explosion of the battery or cell.
9.4 Damaged Cell Warning
If any abnormal feature of a battery or cell is found such as deformation, electrolyte leakage, odor of electrolyte, etc., immediately discontinue the use of the battery or cell(s).
Batteries and cells with the odor of electrolyte leakage shall be placed away from any heat source to avoid combustion or explosion.
