High performance room temperature all-solid-state Na-Se S battery with Na3SbS4–coated cathode via aqueous solution

Review of Multifunctional Separators: Stabilizing the Cathode and the Anode for Alkali (Li, Na, and K) Metal–Sulfur and Selenium Batteries

“…Employing alloy anodes such as Li–Sn, Li–In, and Na–Sn or passivating the metal anode surface with electronically insulating layers can reduce interfacial degradation. ,,,− For example, Ceder et al employed surface hydration to stabilize the SSE–metal interface, which was achieved by exposing the Na 3 SbS 4 electrolyte pellet to ambient air . A concern with using alloy anodes rather than plating/stripping anodes is the reduction in the operating voltage window of the full cell, as well as the degradation of the alloy itself due to the ongoing volume changes.…”

Failure analysis of the Ge-substituted Li6PS5I with bare LiNi0.8Co0.1Mn0.1O2 and performance improvement via Li2ZrO3 coating

“…2b and S3 †). This value is even higher than the room temperature of some solid electrolytes, 59,60 providing the possibility to construct an all-solid-state battery that enables excellent performances under low operating temperatures. The activation energies of both samples can be deduced based on the temperature-dependent Li-ion conductivities.…”

A lignin-derived flexible porous carbon material for highly efficient polyselenide and sodium regulation

“…19–22 Moreover, the dissolution and shuttle phenomena of the soluble intermediate Na polyselenides (SPSs) cause the loss of active material, leading to capacity decay. 23–25 In addition, the sodiation/desodiation process at the Se cathode is sluggish, which limits the charge and discharge ability of the electrode at a high current density, and is beneficial for the shuttle effect of the soluble SPSs. 26–29 Considering the anode processes, the infinite volume change of Na during charge and discharge leads to low coulombic efficiency (CE) and capacity decay.…”
