Self-Discharge Behavior of Lithium/Sulfur Battery Using Aluminum Current Collector
We investigated the self discharge behavior of lithium/sulfur cell using an alumium current collector. The discharge capacity decreased by 14% for oriniginal one after 30 days’ storage at room temperature. The open circuit voltage(OCV) of Li/S battery gradually decreased from 2.45V to 2.38V during the 30 days. The self discharge behavior was related to the decrease of elemental sulfur in the sulfur electrode.
