Ultrafast Microwave Activating Polarized Electron for Scalable Porous Al toward High-Energy-Density Batteries.Chemical etching of metals generally brings about undesirable surface damage accompanied by deteriorated performance.

As a proof-of-concept demonstration, the well-defined porous Al foils featuring regulated surface energy, demonstrate great potential as current collectors in promoting cycling stability, for example, 85.2% reversible capacity sustained after 550 cycles (comparable to commercial Al/C foils), and energy density, that is, approximately 3 times of that by using pristine Al foils for LiFePO4-Li half cells.
