CR2025 3V battery with wires or connectors
Using a battery holder or clamp:
- The safest and most convenient method is to use a specially designed battery holder or clamp.
- The safest and most convenient method is to use specially designed battery holders or clamps.
- These holders usually have built-in terminals and can be used to solder or connect wires directly.
They are suitable for all sizes of button cell batteries, such as CR1025.
Heat shrink tubing method:
- Use heat shrink tubing to wrap the battery and wires together.
- Place the wires on the battery poles first, and then wrap the entire assembly with the heat shrink tubing.
- Heat to shrink the heat shrink tubing to fix the battery and wires.

CR2025 3 volt battery charge & discharge curve
Charge-discharge curves reflect the charging and discharging behavior of battery materials, and the analysis of the charge-discharge curves of button cell batteries is of great significance to the understanding of material properties and electrochemical behavior.
Charge/discharge curves can be presented in several different forms, such as the more common “crossover” curve and “cyclic” curve.

Our li-polymer battery production process
The following is a simplified description of our lithium polymer battery manufacturing process:
1. Mixing
Make a slurry of cathode (positive side) and anode (negative side) electrodes according to the scheme and recipe of the polymer battery model.
2. Coating
Paste is applied to a metal foil (aluminum for cathode, copper for anode). This creates the desired positive and negative plates
3. Cutting
Cut the dried electrode plates to the exact length and width required for the battery cell.
4. Winding
The cathode, anode and diaphragm are wound together. Forms the internal structure of the cell.
5. Injection of electrolyte
Inject electrolyte into the encapsulated cell to allow lithium ions to travel between the positive and negative plates.
6. Sealing & Formation
Encapsulate the cell with an aluminum-plastic film casing to prevent the electrolyte from being exposed. Activate the internal chemical material by charging and discharging.
7. Aging and Testing
Final test of capacity, voltage and overall performance through high and normal temperature aging tests.
