Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

Vapor phase infiltration (VPI) enables atomic‐level dielectric regulation in conductive polymer foams. The VPI‐treated foam exhibits enhanced absorption efficiency per unit thickness (~2.6 times), dynamic frequency tunability (94.5% coverage in 2–18 GHz), and on/off switching ability while retaining performance under acid/alkali exposure and repeated ...
