Inhibiting Selenium Loss in Sodium-Selenium Batteries via a Lewis Acid-Base Dual-Site Host
Abstract
An NB@C host material that combines Lewis acid-base properties was designed to anchor polyselenides, effectively inhibiting the loss of active selenium in sodium-selenium batteries and mitigating corrosion on the Na metal anode. This work provides a general and effective doping combination for the design of advanced selenium host.
