INTEGRATED COOLING AND THERMAL RUNAWAY MITIGATION CONTAINER FOR POUCH BATTERY CELLS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240014466 titled 'INTEGRATED COOLING AND THERMAL RUNAWAY MITIGATION CONTAINER FOR POUCH BATTERY CELLS

Simplified Explanation

The abstract describes a patent application for a pouch battery cell module. The module includes a stack of battery cells and a thermally conductive and compliant material arranged between the cells. It also includes a module container that houses the battery cells and provides structural support. The container has lateral walls that define coolant passages and are designed to direct debris and gases emitted by the battery cells during a thermal runaway event out of the container. The container also has non-structural sides that eject the debris and gases to the external environment. The patent application also discloses a method of assembling the pouch battery cell module.

  • The patent application is for a pouch battery cell module.
  • The module includes a stack of battery cells and a thermally conductive and compliant material between the cells.
  • The module container houses the battery cells and provides structural support.
  • The container has lateral walls that define coolant passages.
  • The lateral walls are designed to direct debris and gases emitted by the battery cells during a thermal runaway event out of the container.
  • The container also has non-structural sides that eject the debris and gases to the external environment.
  • The patent application also discloses a method of assembling the pouch battery cell module.

Potential Applications

  • Electric vehicles
  • Portable electronic devices
  • Energy storage systems

Problems Solved

  • Containment of debris and gases emitted during a thermal runaway event in battery cells
  • Structural support for battery cells
  • Efficient cooling of battery cells

Benefits

  • Improved safety by directing debris and gases away from the battery module
  • Enhanced structural integrity of the battery module
  • Efficient cooling of battery cells to prevent overheating and thermal runaway


Original Abstract Submitted

a pouch battery cell module includes a battery cell stack having first and second pouch battery cells and a thermally conductive and compliant material arranged between the battery cells. the module also includes a module container housing the first and second pouch battery cells and providing structural support therefor and including first, second, third, and fourth lateral walls, with each wall defining at least one coolant passage. each of the first through fourth lateral walls is configured to direct out of the battery module container debris and gases emitted by at least one of the first and second pouch battery cells undergoing a thermal runaway event. the module container also includes non-structural fifth and sixth sides configured to eject to an external environment the debris and gases directed by the first through fourth lateral walls. a method of assembling a pouch battery cell module is also disclosed.
