Investigate how multi-dentate co-solvents affect ion transport and desolvation in lithium metal batteries at cryogenic temperatures.
Analyzed ion transport dynamics in the presence of various co-solvents.
Evaluated desolvation processes at the electrode interface.
Conducted tests at subzero temperatures to measure performance changes.
Multi-dentate co-solvents significantly improved Li+ transport efficiency.
Enhanced desolvation kinetics were observed at the electrode interface.
The overall performance of lithium metal batteries improved when using the optimized co-solvent mixtures.
Abstract
The trade-off between rapid Li + transport in the bulk electrolyte and facile desolvation at the electrode interface poses a fundamental challenge for lithium metal batteries (LMBs) operating at subzero...
