Realizing >5 V batteries is hindered by the instability of electrolytes. Here, a fluoride shielding layer, LiCl-4Li2TiF6, enables high-voltage, high-capacity all-solid-state batteries because of its combined oxidative stability and Li+ conductivity.

Void formation between the solid electrolyte layer and electrode is a critical barrier to the long-term operation of solid-state batteries. Now, an electrochemically inactive yet mechanically soft metallic phase is integrated into the lithium metal anode, which preserves the electrical contact and enables reliable operation in practical cell settings.

Voltage instability of battery materials has hindered the realization of high-voltage all-solid-state batteries (ASSBs). Now, 5 V-class ASSBs are enabled by a fluoride-based shielding layer, LiCl–4Li2TiF6, that combines high oxidative stability and Li+ conductivity. Applied to high-voltage cathodes, the shielding layer mitigates interfacial degradation and enables stable cycling at >5 V, including under high-capacity conditions.
