The lithium battery electrode is generally compacted by a rolling press machine, as shown in Fig. 1. In this process, the electrodes coated on both sides of the particle coating are fed into the gap between the two rolls, and the coating is applied under the action of the roll line load. After being compacted, the electrode will elastically rebound after the seam is slid out, resulting in an increase in thickness. Therefore, the roll gap size and rolling load are two important parameters, usually the roll gap is smaller than the final thickness of the electrode, or the load can cause the coating to be compacted. In addition, the magnitude of the rolling speed directly determines the holding time of the load on the electrode, and also affects the rebound of the electrode, which ultimately affects the coating density and porosity of the electrode.

The lithium battery electrolyte is the carrier for ion transport in the battery. It is generally composed of a lithium salt and an organic solvent. The electrolyte acts as a conducting ion between the positive and negative electrodes of the lithium battery, and is a guarantee for the high voltage and high specific energy of the lithium ion battery. The electrolyte generally consists of a high-purity organic solvent, an electrolyte lithium salt, and necessary additives.It is prepared according to a certain ratio under certain conditions.

The battery stacking machine is one of the key equipment for the production of lithium polymer batteries. The working principle of the semi-auto stacking machine: the positive and negative electrode are loaded into the material box, the machine moves to the left and right, and the pole pieces are picked up in the positive and negative material boxes. After the secondary positioning, the positive and negative electrode pieces are alternately placed on the lamination table.The diaphragm is unwinding actively, and the diaphragm to reciprocate left and right to form a "Z-type " winding.

In the lithium battery laboratory research process, we generally use a pipette to inject electrolyte into the battery. Pipettes can be used to take a small amount of liquid with high accuracy. Pipetting method: before pipetting, ensure that the pipette, tip, and liquid are at the same temperature. When pipetting the liquid, the pipette is held upright and the tip is inserted 2-3 mm below the surface. Before aspirating, you can first aspirate the liquid several times to wet the liquid suction nozzle. Our company can supply kinds of pipettes with different volume, manual model and electric model, they are widely used in lithium battery laboratory research. Thank you for your interested!
