What is the battery capacity of the new energy shuttle bus
Polysulfide Shuttle Study in the Li/S Battery System
Typical ambient Li/S cell discharge curves consist of two plateaus. 1 3 5 7 During the first discharge, molecules of elemental sulfur accept electrons, generating a chain of lithium polysulfides Usually polysulfides with are generated at a high voltage plateau (2.3-2.4 V), and further polysulfide reduction takes place at a low voltage plateau (∼2.1 V).
