Embodiment 1

[0046] like figure 1 As shown, a lithium battery device for an automobile includes an outer casing. The outer casing serves to keep the inside of the lithium battery device dry. It should be noted that the outer casing includes the lower casing 1 and the upper cover 2 matched with the top end of the lower casing 1 . At the bottom of the lower case 1 are a plurality of heat dissipation plates 13 arranged at intervals and fixing feet 11 for fixing the outer case. When the lithium battery device is installed and fixed by the fixing feet 11, the interior of the outer case is separated by the heat dissipation plate 13 at the same time. The heat of the battery is exchanged with the outside of the outer casing, so as to achieve the effect of affecting the life of the lithium battery device caused by the accumulation of heat inside the outer casing. The upper cover 2 is provided with a power interface 21 , and the power cord is sealed and connected to the interior of the lithium bat...

Embodiment 2

[0057] The difference between Example 2 and Example 1 is that the adhesive layer in Example 2 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 adopted battery separator 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, put the non-woven base layer in the adhesive for 30 minutes, take it out, dry at 380°C, and form an adhesive layer on both sides of the non-woven base layer to obtain a diaphragm coarse material;

[0061] Step 3, rolling the raw material of the separator through a calender, and controlling the temperature of the calender to be 72° C. to obtain a battery separator.

Embodiment 3

[0063] The difference between Example 2 and Example 1 is that the adhesive layer in Example 2 includes the following components 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 adopted battery separator 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 40-80cP;

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

[0067] Step 3, rolling the raw material of the separator through a calender, and controlling the temperature of the calender to be 76° C. to obtain a battery separator.

Abstract

The invention discloses a lithium battery device for automobiles, which relates to the technical field of automobiles. The main points of the technical solution include an outer casing and a plurality of lithium battery rows arranged at intervals; the outer casing includes a battery for installing and fixing the lithium battery rows The lower case and the upper cover matched with the top of the lower case, the bottom of the lower case has a plurality of cooling plates arranged at intervals and fixing feet for installing and fixing the outer case; the lithium battery The row includes electrolyte and two symmetrically distributed positive and negative plates located in the electrolyte, and a battery separator is arranged between the positive and negative plates. The invention plays an effective heat dissipation effect through the cooling plates arranged at intervals; and the lithium battery row has a positive plate, a negative plate, and a battery diaphragm located between the positive plate and the negative plate, and has high structural stability, operation stability and safety, and is suitable for use. In the long-term standby and use of the effect.

Description

technical field [0001] The invention relates to the technical field of automobiles, and more particularly 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 categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain lithium in the metallic state and are rechargeable. [0003] The Chinese Patent Publication No. CN107958969A discloses a lithium battery device pack for automobiles, the automobile lithium battery pack includes a plurality of lithium battery cells and a casing, the casing includes an upper casing and a lower casing, the upper casing is The casing and the lower casing are covered together to form a receiving area, and two side walls in the longitudinal direction of the lower casing are correspondingl...
