6 FAQs about [How to activate lead-acid lithium-sulfur batteries]

Why do lithium sulfur batteries fade?

Why does a battery have a high sulfur content?

During the increase of potential the sulfur content decreases at the expense of formation of polysulfides. The most probable explanation for this dynamic within the battery is the dissolution of sulfur, which reacts with reduced sulfur species in the electrode/electrolyte to form the so called polysulfide shuttle mechanism.

How to improve the performance of Li-S batteries?

Therefore, it is crucial to synchronously alleviate the polysulfide shuttling and facilitate the electrochemical reaction kinetics, achieving the entire capability of Li-S batteries. Designing reliable sulfur cathodes is an effective approach to improving the performance of Li-S batteries.

How does sulfur adsorption and catalysis work in Li-S batteries?

In Li-S batteries, the adsorption and catalysis processes of sulfur species on catalysts involve complicated electron transfers, which are challenging to investigate with experimental approaches.

Does liquid sulfur accelerate charging kinetics in LSBs?

A capacity retention of 63% was observed for the pure solid-sulfur formation systems (Figure S19). The differences demonstrate the influential role of liquid sulfur in accelerating the charging kinetics in LSBs. Long-term cycling was performed for the liquid-sulfur Li–S system.
