Embodiment 1

[0046] Such as figure 1 As shown, a lithium battery device for automobiles includes an outer casing. The outer casing plays a role of keeping the inside of the lithium battery device dry. It should be noted that the outer shell includes the lower shell 1 and the upper cover 2 matched with the top end of the lower shell 1 . At the bottom of the lower case 1, there are a plurality of cooling plates 13 arranged at intervals and fixing feet 11 for installing and fixing the outer casing, and then when the lithium battery device is installed and fixed by the fixing feet 11, the inside of the outer casing will The heat is exchanged with the outside of the outer casing, so as to realize the effect of affecting the life of the lithium battery device caused by the heat accumulation inside the outer casing. The upper cover body 2 is provided with a power interface 21 , and the power line is sealed and connected to the inside of the lithium battery device through the power interface 21 ...

Embodiment 2

[0057] The difference between embodiment two and embodiment one is that the adhesive layer in embodiment two includes the following components by weight: 14 parts of polyethylene; 14 parts of glycidyl butyl ether; 2 parts of rubber powder; deionized water 150 servings.

[0058] And the preparation method of the battery diaphragm that adopts comprises the following steps:

[0059] Step 1. Mix 14 parts of polyethylene, 14 parts of glycidyl butyl ether; 2 parts of rubber powder; and 150 parts of deionized water to obtain an adhesive with a viscosity between 40-80 cP;

[0060] Step 2. Control the temperature of the adhesive at 48°C, soak the non-woven base layer in the adhesive for 30 minutes, take it out, dry it at 380°C, and form an adhesive layer on both sides of the non-woven base layer to obtain a separator Coarse material;

[0061] Step 3. Calender the rough material of the separator through a calender, and control the temperature of the calender to 72° C. to obtain a batt...

Embodiment 3

[0063] The difference between embodiment two and embodiment one is that the adhesive layer in embodiment two includes the following components in parts by weight: 16 parts of polyethylene; 16 parts of glycidyl butyl ether; 3 parts of rubber powder; deionized water 180 copies.

[0064] And the preparation method of the battery diaphragm that adopts comprises the following steps:

[0065] Step 1. Mix 16 parts of polyethylene, 16 parts of glycidyl butyl ether; 3 parts of rubber powder; and 180 parts of deionized water to obtain an adhesive with a viscosity between 40-80 cP;

[0066] Step 2. Control the temperature of the adhesive at 48°C, soak the non-woven base layer in the adhesive for 30 minutes, take it out, dry it at 53°C, and form an adhesive layer on both sides of the non-woven base layer to obtain a separator Coarse material;

[0067] Step 3. Calender the rough material of the separator through a calender, and control the temperature of the calender to 76° C. to obtain ...

Abstract

The invention discloses a lithium battery device for an automobile, and relates to the technical field of automobiles. The lithium battery device is characterized by comprising an outer shell and a plurality of lithium battery rows arranged at intervals; the outer shell comprises a lower shell used for installing and fixing the lithium battery rows and an upper cover body matched with the top endof the lower shell, and a plurality of heat dissipation plates arranged at intervals and fixing feet used for installing and fixing the outer shell are arranged at the bottom of the lower shell; eachlithium battery row comprises an electrolyte, a positive plate and a negative plate, wherein the positive plate and the negative plate are symmetrically distributed in the electrolyte, and a battery diaphragm is arranged between the positive plate and the negative plate. The heat dissipation plates arranged at intervals play an effective heat dissipation role; and each lithium battery row is provided with the positive plate, the negative plate and the battery diaphragm positioned between the positive plate and the negative plate so that the structure stability, the operation stability and thesafety are high, and the lithium battery rows are suitable for long-time standby and use.

Description

technical field [0001] The invention relates to the technical field of automobiles, more specifically it relates to a lithium battery device for automobiles. Background technique [0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two types: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. [0003] The Chinese patent with the publication number CN107958969A discloses a lithium battery pack for automobiles. The lithium battery pack for the car includes a plurality of lithium battery cells and a casing, and the casing includes an upper casing and a lower casing. The housing and the lower housing are closed together to form an accommodation area, and the two side walls in the longitudinal direction of the lower housing are correspondingly provided with...
