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. We demonstrate that a self-adaptive SBTM device with MIL-101(Cr)@carbon foam can control the battery temperature below 45 °C, even at high charge/discharge rates in hot environments, and realize self-preheating to ∼15 °C in cold environments, with an increase in the battery capacity of 9.2%. Our approach offers a promising route to achieving compact, liquid-free, high-energy/power-density, low-energy consumption, and self-adaptive smart thermal management for thermo-related devices.

Ultrahigh solar-driven atmospheric water production enabled by scalable rapid-cycling water harvester with vertically aligned nanocomposite sorbent

“…9 Therefore, many novel sorbents such as metal-organic frameworks (MOFs), [10][11][12][13][14] hydrogels, [15][16][17] liquid solutions, 18,19 and composite sorbents 20,21 with extraordinary performance were designed and exploited by the efforts from materials scientists in past years. Lately, these novel sorbents with high water sorption performance and special thermal/electrical effects also inspired energy-related applications such as energy storage, 22,23 thermal management, [24][25][26][27] electricity/fuel generations, 28,29 or co-application. [30][31][32] The MOF-801-based solardriven SAWH prototype was first reported in 2017 with an all-in-one design by integrating light absorber, sorbent, and condenser in one chamber; 33 afterwards, the SAWH prototype was improved by introducing radiative cooling to promoting the water sorption at nightime.…”

Anisotropic Thermal Characterisation of Large‐Format Lithium‐Ion Pouch Cells**

“…[5][6][7] For large-format pouch cells operating at high C-rates (a C-rate expresses current, in units of rated cell capacity per charge/discharge duration in hours), high temperatures and spatial temperature non-uniformities may occur depending on the spatial distribution of electrochemical reactions within the cell [8] and the cooling arrangement. This problem has motivated research to develop more thermally conductive electrodes, [9] effective thermal management techniques [10][11][12] and improved thermoelectrochemical models. [13][14][15][16][17] All of these approaches require accurate knowledge of the cell's heat generation and thermophysical properties.…”

Binder‐Free Growth of Aluminum‐Based Metal–Organic Frameworks on Aluminum Substrate for Enhanced Water Adsorption Capacity

“…As a novel type of adsorbent, metal–organic frameworks (MOFs) have drawn remarkable attention in many fields due to their large surface area, abundant unsaturated sites, and tunable topologies and pore size. [ 1 ] Especially, the steep stepwise uptake of water vapor and moderate regeneration temperature make them excellent candidates for water adsorption applications such as heat dissipation, [ 2 ] adsorption heat pumps and chillers, [ 3 ] atmospheric water harvesting, [ 4 ] and humidity control.
