Near-Zero-Energy Smart Battery Thermal Management Enabled by Sorption Energy Harvesting from Air.

ABSTRACT: Effective battery thermal management (BTM) is critical to ensure fast charging/discharging, safe, and efficient operation of batteries by regulating their working temperatures within an optimal range. However, the existing BTM methods not only are limited by a large space, weight, and energy consumption but also hardly overcome the contradiction of battery cooling at high temperatures and battery heating at low temperatures. Here we propose a near-zero-energy smart battery thermal management (SBTM) strategy for both passive heating and cooling based on sorption energy harvesting from air. The sorption-induced reversible thermal effects due to metal-organic framework water vapor desorption/sorption automatically enable battery cooling and heating depending on the local battery temperature.
