Problems solved by technology

Especially lithium-ion batteries and nickel-metal hydride batteries, these batteries have been used in hybrid electric vehicles and other application equipment, these batteries have a large output power, so their own heat is relatively large, traditional natural cooling or wind The cold method can no longer meet the heat dissipation requirements of the battery in the above environment. Therefore, some designers currently use an additional heat conduction plate outside the battery to absorb the heat of the battery, and a heat conductor is used between the heat conduction plates to dissipate heat. The body dissipates heat, and the heat conductor is mainly composed of water, so the sealing of the battery pack becomes a crucial issue. If the heat conductor leaks, it will lead to extremely dangerous consequences.

Abstract

The invention discloses a preparation method of a battery module sealing ring. Through step 1, prepare raw materials, vulcanizing agent is 0.5%-10%, liquid silica gel is 99.5%-90%; step 2, mix raw materials; step 3, filler; step 4, baking molding, baking temperature is 30℃- 80°C, the baking time is 10-100 minutes; Step 5, take out the sealing ring, and the sealing ring with good sealing performance can be produced.

Description

technical field [0001] The invention relates to a preparation method of a sealing ring, in particular to a preparation method of a battery module sealing ring. Background technique [0002] At present, batteries are more and more used in certain fields, and in these fields, the excess heat emitted by the battery core during operation must be removed in time to prevent the battery core from overheating. Especially such as lithium-ion batteries and nickel-hydrogen batteries, these batteries have been used in hybrid electric vehicles and other application equipment. These batteries have a large output power, so their heat generation is relatively large. Traditional natural cooling or wind The cold method can no longer meet the heat dissipation requirements of the battery in the above environment, so some designers currently use an additional heat conduction plate outside the battery to absorb the heat of the battery, and use a heat conductor to dissipate heat between the heat c...
