High Performance Sodium-ion Battery Materials
In contrast to lithium, sodium is one of the most abundant elements in the Earth’s crust, making sodium-ion batteries (SIBs) a compelling, sustainable, and lower-cost alternative to lithium-ion technology. Operating on a similar intercalation principle, the SIB cathode (positive electrode) releases sodium ions during charging and accepts them during discharge, while the anode (negative electrode) stores those ions during charge and releases them back upon discharge. Because sodium ions possess a larger atomic radius than lithium ions, both cathode and anode materials require tailored crystal structures capable of accommodating this volume and facilitating efficient ion transport.
