Which is better, custom-made lithium batteries or finished products?
22 2025-05-12
Customized lithium batteries flexibly adapt to special needs, enhance safety and lifespan, and are the preferred choice for industrial-grade scenarios. Finished batteries are ready to use immediately and offer high cost performance, making them even better for civilian consumption. ""
I. Advantages and Applicable Scenarios of Customized Lithium Batteries
Flexibly adapt to demands
Adjustable parameters: Voltage, capacity, size, etc. can all be designed as needed to meet the requirements of special equipment or industrial-grade applications. For instance, customizing an adjustable working voltage range (such as flexible combination of 3.2V-3.7V individual cell voltages) can solve the problem of mismatch between the parameters of the finished battery and the equipment.
Performance optimization: Enhanced protective measures can be taken in scenarios such as high and low temperature environments (such as -45℃ to 60℃), shock resistance, and vibration prevention to improve safety.
2. Safety and reliability
The safety features such as short-circuit resistance, overcharge and overdischarge resistance, and needle-puncture resistance can be enhanced through customization, and solid colloidal electrolytes are adopted to avoid leakage problems.
Manufacturers can add protective designs for specific environments (such as high temperatures and humidity), such as BMS (Battery Management System) and multiple circuit protections.
3. Long service life and high cost performance
The lifespan of custom-made batteries can reach over 6 years, with more than 1,000 cycles. The long-term usage cost may be lower than that of frequently replacing ready-made batteries.
4. Applicable scenarios
Industrial equipment: such as special vehicles, medical equipment, energy storage systems and other fields with special requirements for parameters.
High security requirements: such as aerospace, military equipment and other scenarios that need strict security protection.
Ii. Advantages and Applicable Scenarios of Finished Lithium Batteries
Buy and use immediately, low cost
Standardized production reduces unit prices and is suitable for scenarios with limited budgets or simple demands (such as consumer electronics).
Stable quality
The parameters have been verified by the market and have strong compatibility. For instance, 18650 battery cells are widely used in notebook computers, power tools, etc.
Fast delivery
No customized process is required. The supply chain is mature and can be purchased quickly.
Applicable scenarios
Civilian consumption field: Products such as mobile phones, tablets, and ordinary electric vehicles that have no special requirements for parameters.
General-purpose equipment: such as household energy storage devices, ordinary power tools, etc.
Iii. Selection Suggestions
Give priority to choosing customized scenarios
The equipment has special requirements for voltage, size and environmental adaptability.
It needs to be used for a long time at high intensity and has high requirements for service life (such as industrial equipment).
The budget is sufficient and willing to pay a premium for security and performance.
Give priority to scenarios where finished products are selected
The requirements are standardized and no special parameter adjustments are required.
Limited budget or sensitive to delivery time.
The application scenarios have relatively low risks (such as household electronic products).
