Production process
High-Temperature Soaking
The process begins with high-temperature soaking, where the Prismatic Cell Aluminum Battery Cases are exposed to temperatures between 40-60°C to enhance the wetting of the electrodes with the electrolyte. This step helps reduce the time required to reach the optimal wetting level before the formation process starts.
Initial Charging
After soaking, the Lithium Batteries Square Aluminum Shells undergo initial charging, also known as pre-charging. A low charging current is applied until a low voltage (e.g., 1.5V) is reached. This step protects the copper-based current collector from corrosion and allows most of the gas generation during the first cycle to be completed.
Formation Cycling
This involves at least one and possibly several charge and discharge cycles with defined current and voltage limits. During this stage, the Solid Electrolyte Interphase layer is formed at the anode, which is crucial for protecting the anode from reactions with electrolyte components and influencing the battery's subsequent performance.
Aging
The Powerwall Lithium battery Packs are then aged at a defined state of charge and temperature. This process completes the cell formation and serves as a self-discharge test. If there is an increased capacity loss during storage, it may indicate unwanted self-discharge
Standard Configuration
1. Square Aluminum Shell Lithium Iron Phosphate Battery: A common standard configuration includes a nominal capacity of 50Ah, a nominal voltage of 3.2V, and an internal resistance of ≤0.7mΩ at 1kHz. The charge/discharge current is typically 0.5C, with a maximum continuous charge/discharge current of 3C and pulse charge/discharge current of 5C.
2. Dimensions and Weight: The battery dimensions are width 135.3±0.3mm, thickness 29.3±0.7mm, and height 185.3±0.5mm, with a weight of 1395±50g. These specifications ensure compatibility with various applications, including vehicle power systems and energy storage systems.
3. Operating and Storage Conditions: The charging working temperature range is 0ºC to 55ºC, while the discharging working temperature range is -20ºC to 55ºC. For storage, short-term storage (within a month) can be done between -20ºC and 45ºC, and long-term storage (within a year) between 0ºC and 35ºC.
4. Self-Discharge Rate: The monthly self-discharge rate is ≤3% when stored at (25±2)ºC with a 30% to 50% SOC. This low self-discharge rate ensures that the battery maintains its charge over extended periods, making it suitable for applications where frequent charging is not feasible.
Type Summary
1. Lithium Batteries Square Aluminum Shell: These batteries are designed with a robust square aluminum shell, providing mechanical protection and thermal stability. The square shape allows for efficient packing and integration into various systems, such as electric vehicles and energy storage units.
