Thermal management of reactive gel catalysts in electric vehicle battery packs
Introduction
With the popularity of electric vehicles (EVs), thermal management of battery packs has become a key issue. The battery pack will generate a lot of heat during charging and discharging. If it cannot be effectively managed, it may lead to degradation of battery performance, shortening of life and even safety issues. Reactive gel catalysts, as a new material, show great potential in thermal management of electric vehicle battery packs. This article will introduce in detail the principles, applications, product parameters and their specific applications in thermal management of electric vehicle battery packs.
Principle of reactive gel catalyst
1.1 Basic concepts of reactive gel catalysts
Reactive gel catalyst is a material with a high specific surface area and a porous structure that is capable of catalyzing chemical reactions under specific conditions. Its unique structure allows it to absorb and release heat efficiently, thus playing an important role in the thermal management of the battery pack.
1.2 Working principle of reactive gel catalyst
The reactive gel catalyst adsorbs and releases heat through its porous structure, and can absorb excess heat when the temperature of the battery pack increases and release stored heat when the temperature drops. This bidirectional adjustment mechanism allows the battery pack to maintain a stable temperature under different operating conditions, thereby improving the battery performance and life.
