The energy density of supercapacitors -- battery-like devices that can charge in seconds or a few minutes -- can be improved by increasing the 'messiness' of their internal structure. Researchers used ...

Schematic illustration of piezoelectric enhancement via the synergistic modulation of tetragonal–pseudocubic (T–PC) phase boundaries and ordered/disordered oxygen octahedral tilt boundaries.

Peking University, August 13, 2025: In a significant leap toward next-generation lithium battery design, researchers from the School of Materials Science and Engineering at Peking University, led by ...
