Abstract The mass adoption of electric vehicles is hindered by the inadequate extreme fast charging (XFC) performance (i.e., less than 15 min charging time to reach 80% state of charge) of commercial high-specific-energy (i.e., >200 Wh/kg) lithium-ion batteries (LIBs). Here, to enable the XFC of commercial LIBs, we propose the regulation of the battery’s self-generated heat via active thermal switching. We demonstrate that retaining the heat during XFC with the switch OFF boosts the cell’s kinetics while dissipating the heat after XFC with the switch ON reduces detrimental reactions in the battery. Without modifying cell materials or structures, the proposed XFC approach enables reliable battery operation by applying

To efficiently unlock the cooling power of sweat for human body remains a great challenge for next-generation textiles. Here the authors report an integrated cooling (i-Cool) textile showing high evaporation ability and sweat evaporation cooling efficiency for personal perspiration management.

Nanoparticles are often used as nanothermometers by measuring their luminescence from upconverted energy under illumination. The authors uncover the artificial appearance of a temperature rise at high excitation intensities due to effects involving higher energy states.

Low thermal conductivities in nanomeshes have been attributed to both wave-like and particle-like behaviour of phonons. Here, the authors use periodicity-controlled silicon nanomeshes to show that the particle backscattering effect dominates for periodicities above 100 nm and temperatures above 14 K.
