Embodiment 1

[0066] first combined with figure 1 Explain the fully automatic production line for power lithium batteries:

[0067] The production line consists of pole piece production unit, battery assembly unit, battery liquid injection unit and delivery processing unit. The automatic control system of each unit mainly uses PLC, industrial computer, hydraulic and pneumatic components for electrical control, and the transmission and transfer are in charge of the conveyor belts inside and between the units.

[0068] pole piece production unit

[0069] The pole piece production unit is composed of 2 mixers 1, 2 coating machines 2, 1 rolling machine 3, 1 continuous drying machine 4, 2 slitting machines 5 and 8 punching machines 6, in turn The pole piece production unit performs the processes of mixing ingredients, coating, rolling, baking, slitting and punching pole pieces, and transfers them to the battery assembly unit through the conveyor belt after completion.

[0070] The operation...

Embodiment 2

[0103] The negative electrode material in Example 1 is a modified negative electrode material, and its preparation method steps: mix 90Kg of modified lithium titanate, 15Kg of acetylene black and 15Kg of PVDF evenly, then add 20Kg of organic solvent N-methyl-2-pyrrolidone, and mix well , that is;

[0104] The preparation method of the modified lithium titanate is as follows: take 18Kg of lithium hydroxide, 12Kg of metatitanic acid, and 4Kg of terpineol, add 300Kg of deionized water, heat to 55°C, and keep for 4 hours to obtain a suspension Add 17Kg of oleic acid, 3Kg of hydrogenated castor oil, 10Kg of graphene, 3Kg of titanium dioxide, 3Kg of dibenzoyl peroxide, 15Kg of silane coupling agent, and 8 Kg of surfactant into the suspension, stir evenly, and heat to 55°C , kept for 2 hours to obtain a modified suspension; filter the modified suspension with a microfiltration membrane, sinter the obtained particles at 1150° C. for 7 hours, and cool to room temperature.

Embodiment 3

[0106] In the present embodiment, oleic acid is vulcanized and modified, and the modification method is: in a three-necked flask equipped with a stirring device, add 50 g of oleic acid, and under constant stirring, add 15 g of sulfur monochloride (S 2 Cl 2 ), control the reaction temperature below 40°C, after the dropwise addition, continue to react for 2 hours, slowly add about 100 ml of sodium polysulfide solution to the reactant, stir and react fully, remove the water layer, and then add a little reducing Iron powder, remove free sulfur in the reaction system, filter to obtain oily matter, that is all.

[0107] The preparation method of the modified negative electrode material, the steps are: mix 90Kg of modified lithium titanate, 15Kg of acetylene black and 15Kg of PVDF evenly, then add 20Kg of organic solvent N-methyl-2-pyrrolidone, and mix evenly to get ready;

[0108] The preparation method of the modified lithium titanate is as follows: take 18Kg of lithium hydroxide,...

Abstract

The invention relates to a full-automatic production line of a power type lithium battery and a production process thereof. It is mainly composed of pole piece production unit, battery assembly unit, battery liquid injection unit and delivery processing unit. The electrical control system of key equipment of each unit is composed of PLC, industrial computer, hydraulic and pneumatic components. The computer collects data and realizes the functions of storing and reading data of the whole line. The main effect is reflected in: the mutual matching of the production efficiency of each unit is realized through the key adjustment of the production parameters, and the conveyor belt is used in the intermediate link, which finally realizes the full automation of the production process; the production line is compatible with the production requirements of multi-standard batteries, and the product change only needs to be adjusted The production can be realized by changing the equipment parameters and part of the tooling and fixtures, meeting the order-based production requirements of the products; the key equipment and technical processes involved in the line are all independently developed, reliable and stable in operation, and have a high cost performance.

Description

technical field [0001] The invention relates to the technical field of lithium battery production equipment and production technology, and specifically refers to a fully automatic production line for power type lithium batteries and its production technology. Background technique [0002] With the shortage of energy and the pressure of the world's environmental protection, large-capacity power batteries have gradually become the main body of power sources. Among them, lithium batteries, as green batteries, will not cause secondary pollution and have no memory effect, etc., and gradually become the power source market. App's first choice. The power type lithium battery has the advantages of high energy, high battery voltage, wide operating temperature range, long storage life, high power tolerance, low self-discharge rate, light weight, green environmental protection, and no memory effect. It is mainly used in hybrid power Vehicles, electric vehicles, electric bicycles, and ...
