Cylindrical lithium-ion battery with dual flexible liquid cooling plates

Abstract

The invention concerns an innovative cooling system integrated into lithium-ion (Li-ion) batteries. Comprising two flexible liquid-cooling plates, this system aims to dissipate the heat generated by cylindrical Li-ion batteries, in particular the heat accumulated in the center of the battery. These flexible plates incorporate a specific mixture of water and glycol, optimizing their thermal conductivity while preventing corrosion and algae formation. The cooling process is based on liquid convection, ensuring optimal battery operation and extended battery life.
