Description

Technical Field

[0001] The utility model relates to the field of lithium batteries, in particular to a lithium battery electrolyte preparation and mixing device. Background Art

[0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements, so lithium batteries have not been used for a long time. With the development of microelectronics technology, the number of miniaturized devices has increased, which has put high demands on power sources. Lithium batteries have entered the large-scale practical stage. Lithium batteries refer to batteries containing lithium (including metallic lithium, lithium alloys and lithium ions, lithium polymers) in the electrochemical system. Lithium batteries can be roughly divided into two categories, lithium metal batteries and lithium ion batteries. Lithium metal batteries are usually non-rechargeable and contain metallic lithium. Lithium ion batteries do not contain metallic lithium and are rechargeable.

[0003] At present, in the preparation process of lithium battery electrolytes, mixing equipment is usually used for mixing. When using the current mixing equipment, it is not convenient to disperse the electrolyte solution into water, which reduces its mixing speed and is not conducive to current use. It also greatly affects the preparation of the electrolyte. Therefore, those skilled in the art provide a lithium battery electrolyte preparation mixing equipment to solve the problems raised in the above background technology. Utility Model Content
