Preparation method of sodium tablets
Before conducting electrochemical performance tests of materials, the experimental battery is first assembled. In order to avoid the influence of multiple factors, a two-electrode half-cell is usually assembled for measurement, and a metal sodium sheet is generally used as the reference electrode and the pair electrode. The preparation process of sodium anode in button batteries is to cut sodium blocks, roll sodium blocks, and flush sodium tablets.
Traditional preparation methods have many limitations, mainly reflected in the following aspects:
1. The operation is cumbersome, four steps, which increases the preparation time of deduction power.
2. Due to manual operation, the consistency of different batches or even the same batch cannot be guaranteed, and the surface state of size, thickness and surface will be different.
3. The surface is uneven, which is easy to produce dendrites, break through the diaphragm, affect the performance and even short circuit.
4. After preparing sodium tablets, there will be residual debris, which is not easy to handle.
The emergence of commercial sodium tablets avoids most of the problems of traditional preparation and provides more convenient and high-quality consumables for scientific research and development.
