6 FAQs about [Sodium-sulfur battery technical issues]
What problems do sodium sulfur batteries face?
Room temperature sodium–sulfur batteries face safety problems caused by the anode sodium dendrites, the insulation problem of the cathode sulfur, the shuttle effect of the intermediate product polysulfide and the loss of active materials caused by its dissolution.
Can sodium-sulfur batteries operate at high temperature?
The review focuses on the progress, prospects and challenges of sodium-sulfur batteries operating at high temperature (~ 300 °C). This paper also includes the recent development and progress of room temperature sodium-sulfur batteries. 1. Introduction
How long does a sodium sulfur battery last?
Lifetime is claimed to be 15 year or 4500 cycles and the efficiency is around 85%. Sodium sulfur batteries have one of the fastest response times, with a startup speed of 1 ms. The sodium sulfur battery has a high energy density and long cycle life. There are programmes underway to develop lower temperature sodium sulfur batteries.
How does a sodium sulfur battery work?
The sodium-sulfur battery realizes the conversion between chemical energy and electrical energy through the electrochemical reaction between metallic sodium and elemental sulfur . When discharging, sodium metal produces Na + and electrons. Na + moves with the electrolyte through the separator to the sulfur cathode.
