Embodiment 1

[0041] A kind of production technology of fast charging lithium battery, its steps are as follows:

[0042] a. Weighing of each raw material: shell 76g, multi-component positive electrode 186g, copper foil 30g, electrolyte 50g, mixed negative electrode 65g, separator 0.2㎡, conductive agent 0.6g, binder PVDF 0.5g, diluent 40 grams of NMP, 0.9 grams of thickener CMC, 20 grams of aluminum foil, 0.8 grams of tabs, 0.5 grams of insulating tape;

[0043] b. Drying of raw materials: vacuum bake the multi-component positive electrode in step a, bake the conductive agent at normal pressure, and bake the adhesive at normal pressure;

[0044] c. Stirring of the slurry: Pour NMP into a vacuum mixer, and add PVDF into it; add the positive electrode dry material in four times on average; stir at high speed under vacuum for 3-5 hours; discharge and prepare for coating;

[0045] d. Electrode coating: the slurry is evenly coated on the surface of the aluminum foil on a precision coating machi...

Abstract

The invention belongs to the technical field of lithium battery production, and particularly relates to a production technology of a quick-charge lithium battery.The production technology of the quick-charge lithium battery comprises the following steps of a, weighing of raw materials, b, drying of the raw materials, c, paste stirring, d, pole piece coating, e, pole piece rolling, f, pole piece punching, g, lamination, h, battery shelling and welding, i, battery filling, j, battery formation and grading, and k, battery pack assembling.Charging time can be effectively shortened, and the production cost can be greatly reduced.The lithium battery produced through the technology has the advantages that charging is fast, wherein charging can be finished within 10-60 min; the service life is long, wherein the lithium battery can be used 10000-20000 times; the temperature range is wide, wherein the lithium battery can be used at the temperature from -30 DEG C-70 DEG C; safety is high, and lithium titanate has no safety accident all over the world; the cost is low, wherein the cost is one half that of a common lithium battery.

Description

technical field [0001] This invention belongs to the technical field of lithium battery production, and specifically relates to a formula production process for fast charging lithium batteries. Background technique [0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from a rechargeable battery. Lithium-ion batteries are different from lithium-ion polymer batteries. The inventor of the lithium battery is Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements for power supply. Lithium batteries have entered a...
