Summary: The study found that 1,3-dialkyltriazolium iodides exhibit high chemical and thermal stability, with significant changes in electrolyte properties upon addition of different iodine content, where iodine addition usually leads to a decrease in melting point and an increase in conductivity. Compared to imidazolium iodides, triazolium compounds show higher efficiency and longer battery life, possibly due to their non-hygroscopic nature.
