Title:
SI-CONTAINING ALLOY FOR THE ANODE OF PROTON-CONDUCTING RECHARGEABLE BATTERIES
Document Type and Number:
WIPO Patent Application WO/2022/145026
Kind Code:
A1
Abstract:
Provided are proton-conducing batteries that utilize Si or Si alloys as a hydride forming component of an anode electrochemically active material. The proton-conducting batteries include: a cathode including a cathode electrochemically active material capable of storing and releasing hydrogen; an anode including an anode electrochemically active material comprising an alloy represented by SixM1-x wherein M comprises one or more non-Si group 14 elements, and wherein 0 ＜ x＜ 1, wherein a microstructure of the anode electrochemically active material is amorphous, polycrystalline, a mixture of nanocrystalline and amorphous, or a combination of polycrystalline, nanocrystalline and amorphous; and a non-aqueous electrolyte between the anode and the cathode.
