Title:
BULK SI-ANODE FOR USE IN PROTON-CONDUCTING RECHARGEABLE BATTERIES
Document Type and Number:
WIPO Patent Application WO/2022/145025
Kind Code:
A1
Abstract:
Provided are proton conducing rechargeable batteries that display excellent capacity. The rechargeable batteries include a cathode comprising a cathode electrochemically active material capable of storing and releasing hydrogen, optionally including Ni, and an anode, the anode including an anode electrochemically active material of one or more group 14 elements, the anode electrochemically active material in the powder form and associated by a binder, wherein a microstructure of the anode electrochemically active material is polycrystalline, a mixture of nanocrystalline and amorphous, or a combination of polycrystalline, nanocrystalline and amorphous. The cells include a non-aqueous electrolyte and are a characterized by a discharge capacity above 800 mAh/g of the anode electrochemically active material above 1 Volt.
