A dealloying approach to synthesizing micro-sized porous tin (Sn) from immiscible alloy systems for potential lithium-ion battery anode applications

Strategies to enable microsized alloy anodes for high-energy and long-life alkali-ion batteries

“…This is largely due to Sn's inherent low melting point combined with the inevitable electrochemical it undergoes. Song et al 127 tackled this challenge by fabricating 3D continuous microscale Sn with a porous structure from immiscible Al-Sn alloys. Impressively, the resultant microporous Sn anode showcased a high initial capacity, measuring 818 mA h g −1 , and a commendable CE of 99% (Fig.…”
