We know polysulfide is produced in Li-ion and Na-ion batteries during the charge and discharge process. My question in Al-ion batteries. Is it possible that polysulfide is also produced? I have this subject because Al has 3 electrons and S needs 2 electrons, then how will this polysulfide work?
In Al-ion batteries, polysulfides can form if sulfur or sulfur-containing compounds are used as the cathode.
Al³⁺ can react with sulfur to form aluminum polysulfides (Al₂Sₓ), but their electrochemistry differs from Li/Na systems because Al³⁺ transfers three electrons, altering the redox pathways and possible stoichiometries. The mechanism would involve multi-electron conversion rather than the stepwise Li/Na polysulfide dissolution process.
Abdullah Al Mahmud, thank you, please, if you have more details, benefit me
