The main cause of battery vulcanization is that a layer of white and hard crystals is attached to the surface of the negative plate inside the battery. After charging, it is still unable to peel off the surface of the negative plate and convert the lead sulphate into an active substance. This is sulphur. Acidification, abbreviated as

When the vulcanization and polarization phenomena are eliminated successfully, the REFLEXYM charging method is carried out immediately to protect the batteries, and the batteries can be controlled by intermittent charging at this stage. The phenomenon of temperature rise is helpful to prolong the life of the battery.
Therefore, inversely vulcanized polymers are evolving materials in Li–S batteries. Due to the high temperature of inverse vulcanization, low boiling monomers are excluded as they either evaporate or undergo premature homopolymerization. To cover wider range of monomers, catalyst is required to reduce reaction temperature.
In 2013, in a pioneering work by Pyun et al. a new method of synthesizing stable sulfur-rich polymers by terminating the bi-radicals of sulfur at the end of the polysulfide chains by crosslinking it with 1,3-diisopropenylbenzene (DIB) was introduced. Often this chemical modification is termed as inverse vulcanization.
Apart from the several metal DEDC based catalysts, the compounds such as 18-crown-6 ether, potassium dodecanethiol and potassium isopropyl xanthate also exhibited the best results in terms of glass transition, rate, and yield . Figure 2. (a) Mechanism of catalytic inverse vulcanization using metal dithiocarbamate as catalyst .
The inversely vulcanized polymers are found to be an excellent candidate for preparing active cathode material in Li–S batteries with extended battery life . The mechanism of redox transformation proceeds via organosulfur pathway and has very strong resemblance to the operations of conventional Li–S batteries [12, 20].
Uncatalyzed inverse vulcanization have been found effective in the case of vinyl monomers having boiling point either above or close to the inverse vulcanization reaction temperature, and having non-polar character are well reactive in this system [20, 35, 36].
