US 2023/0155208 A1 · HEAT-DISSIPATING BATTERY PACK

Abstract

A heat-dissipating battery pack is disclosed. The heat-dissipating battery pack may include at least a pouch battery cell. The at least a pouch battery cell may include a pair of electrodes. The at least a pouch battery cell may include a pouch, wherein the pouch substantially surround the pair of electrodes. The at least a pouch battery cell may include an electrolyte within the pouch. The at least a pouch battery cell may include a vent of the at least a pouch battery cell, wherein the vent of the at least a pouch battery cell is configured to discharge battery ejecta ejected during a thermal runaway as a function of temperature and pressure.
