Article Synopsis
- High-voltage lithium metal batteries (HV-LMBs) are seen as a key solution for high energy density storage, but existing electrolytes struggle to stabilize both the lithium anode and high-voltage cathodes efficiently.* -
- A new dual-interphase-stabilizing electrolyte is introduced that eliminates the need for expensive Li salts, using a sulfolane solvent and specially designed additives to create stable protective layers for both the anode and cathode.* -
- Testing shows that cells with this electrolyte can last over 500 cycles and deliver a high energy density of 435 Wh/kg, making it a promising option for safer and more cost-effective large-scale battery applications.*
A majority of flexible and wearable electronics require high operational voltage that is conventionally achieved by serial connection of battery unit cells using external wires. However, this inevitably decreases the energy density of the battery module and may cause additional safety hazards. Herein, a bipolar textile composite electrode (BTCE) that enables internal tandem-stacking configuration to yield high-voltage (6 to 12 V class) solid-state lithium metal batteries (SSLMBs) is reported.

Herein, the porous structure was constructed in poly(oxymethylene)/multi-wall carbon nanotube (POM/MWCNT) nanocomposites via assisting by poly(l-lactide) (PLLA). First, the POM/PLLA/MWCNT (S-PMLNT) nanocomposites were obtained by melt mixing and compression molding.
