Nikon XT 225 scan of two LG 21700 M50 cells after thermal abuse testing (below). In the cell on the left (green) the "jellyroll" (the cyclinder of wrapped up electrodes in the centre of the cell) has ...
The images, below, show X-ray macro-CT results of a commercial 18650 cell (a) showing a 3D reconstruction of the whole cell and orthogonal slices in the XY and YZ planes before thermal runaway and (b) ...
The use of silicon anodes in lithium-ion batteries improves energy storage but presents swelling issues that impact lifespan and electrochemical stability.
Electrochemical reduction is a promising ... specific active sites through deliberate defects in the cubic copper structure. By slightly dislocating some copper atoms, they prevented surface ...
Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a new approach that combines generative artificial intelligence (AI) and first-principles simulations to predict three ...
These ‘iontronic’ devices interact seamlessly with living matter and, in a proof-of-concept demonstration, the team designed a biological sensor capable of measuring the heartbeat of cardiac cell ...
