WASHINGTON, January 12, 2021 Sodium-ion batteries are a potential replacement for lithium batteries, but the anodes positively charged electrodes that work well for lithium-ion batteries don t provide the same level of performance for sodium-ion batteries.
Amorphous carbon, which lacks a crystalline structure, is known to be a useful anode, because it has defects and voids that can be used to store sodium ions. Nitrogen/phosphorus-doped carbon also offers appealing electrical properties.
