Description

Technical Field

[0001] The utility model relates to the technical field of battery production, and more specifically, to a raw material crushing and grinding mechanism. Background Art

[0002] Sodium ion battery is a secondary battery that relies on the movement of sodium ions between the positive and negative electrodes to complete charging and discharging. Its working principle is similar to that of lithium ion batteries. The positive electrode of the sodium ion battery usually uses vanadate materials, while the negative electrode uses carbon materials or vanadium oxides. When charging, sodium ions migrate from the positive electrode to the negative electrode and are embedded in the carbon or vanadium oxide at the negative electrode. When discharging, the sodium ions are released from the negative electrode and return to the positive electrode, while releasing the stored energy. The raw materials of sodium ion batteries need to be crushed and ground during production. However, since most of the crushing and grinding equipment are independent and separate, the raw materials processed by the crushing equipment need to be transferred to the grinding equipment, resulting in an increase in the raw material transfer process. The crushing and grinding process is relatively time-consuming and labor-intensive, affecting the working efficiency of the crushing and grinding of raw materials for sodium ion batteries. The utility model designs a raw material crushing and grinding mechanism to solve the above problems. Utility Model Content
