Here, the authors design a “beyond aqueous” colloidal electrolyte with ultralow salt concentration and inherent low freezing point and investigate its colloidal behaviors and underlying mechanistic principles to stabilize cryogenic Zn metal battery.
All-solid-state batteries (ASSBs) working at room and mild temperature have demonstrated inspiring performances over recent years. However, the kinetic attributes of the interface applicable to the subzero temperatures are still unidentified, restricting the low-temperature interface design and operation.
As a result, the CON colloid electrolyte enables a more stable Li|LiNi 0.8 Mn 0.1 Co 0.1 O 2 cell cycling at an ultrahigh upper cut-off voltage of 4.7 volt than the commercial one at room temperature.
More importantly, the Li metal anode remains a smooth, dendrite-free surface after 150 cycles at a low temperature at 0.2 C, indicating the uniform Li+ ions deposition due to excellent low-temperature ionic conductivity of KSCE (Fig. 7c). Table 1. Summaries of solid-state batteries operated at low temperatures. Fig. 7.
The resulting composite electrolyte exhibits a mechanical rigidity of 26.9 MPa and a room temperature ionic conductivity of 3.37 × 10 −4 S cm −1, which enables stable cycling of solid-state LiFePO 4 /Li batteries at room temperature without the formation of lithium dendrites.
