The core of high-rate lithium battery customization lies in balancing rate performance, safety, and stability. Key considerations revolve around parameter matching, safety design, and quality control.
1.Core parameters precisely matched
Clearly define the required discharge rate, distinguishing between continuous discharge rate and instantaneous discharge rate to prevent usage anomalies caused by ambiguous labeling.
Verify voltage and capacity specifications. Cell voltage (e.g., 3.7V) and series/parallel configuration (e.g., 3S2P) must align with the device's power consumption requirements. Capacity should be reasonably set based on the rate capability characteristics.
Match the operating environment parameters, clearly define the operating temperature range and charge/discharge cut-off voltages, and avoid exceeding the battery's tolerance thresholds.
2.Safety Design and Protection
Select battery cells compatible with high-rate applications, prioritizing power-type cells to ensure low internal resistance and controllable heat generation during high-current discharge.
Enhanced BMS (Battery Management System) functionality must support overcharge, over-discharge, overcurrent, and short-circuit protection, with response speeds optimized for high-rate scenarios.
Design thermal management structures. High-rate discharging can cause overheating, requiring reserved cooling space or the use of thermal interface materials to prevent thermal runaway.
3.Quality and Process Control
Verify cell consistency by requiring suppliers to provide consistency test reports for cell internal resistance, capacity, and voltage prior to customization, thereby minimizing performance deviations after cell assembly.
Confirm that the manufacturing process, welding techniques (such as laser welding), and encapsulation materials meet the requirements for high-magnification operational strength, preventing poor contact under vibration or high-current conditions.
Third-party testing is required. After customization, products must pass rate discharge testing, cycle life testing, and safety impact testing to ensure compliance with standards.
4.After-Sales Support and Compatibility Verification
Define warranty terms explicitly, specifying cycle life warranties for high-rate scenarios (e.g., capacity retention ≥80% after 500 cycles).
Conduct small-batch trial production verification by first customizing samples for real-world testing. Proceed with mass production only after confirming no issues such as overheating or power failure.
