Applications of Li-Ion Batteries Based on Nanocomposite Materials Nowadays, the integration of nanocomposite materials has attracted considerable interest and stands out as a crucial breakthrough in the field of energy storage, specifically within the domain of lithium-ion batteries .
This study shows that MgO significantly improves the stability and discharge capacity of Li–S batteries by functioning as a polysulfide–trapping agent. It sequesters dissolved polysulfide intermediates from the sulfur cathode, thereby enabling the active material to persist in electrochemical reactions.
We demonstrate via electrochemical testing of symmetric cells at 2.5 MPa and 30∘C that 1% magnesium content in the alloy increases the stripping capacity compared to both pure lithium and higher magnesium content alloys by balancing these effects. All-solid-state lithium-based batteries require high stack pressure during operation.
