Document Type and Number:
WIPO Patent Application WO/2024/061197
Kind Code:
A1
Abstract:
A battery and a means of transport, which relate to the technical field of lithium batteries. When the battery is in an operating condition of use, a battery casing includes two or more separate flat sealing cavities for phase-change heat transfer in the gravity direction and/or horizontal direction of a side surface casing wall and/or an upper bottom surface and/or a lower bottom surface; part or all of cavity walls of the sealing cavities are part of the casing; and a phase-change heat transfer working medium filled in the sealing cavities can be in direct contact with the battery casing to carry out heat transfer. A thermal management system based on the battery has a better capability to inhibit thermal runaway caused after stalling, and a space utilization rate of a battery system is increased.
