Abstract: In an example of a method, a halogenide-hydrocarbon, an aprotic hydrocarbon solvent, and a reductant are combined to initiate a reaction that forms intermediate particles having a microporous framework. The intermediate particles are subjected to a heat treatment at a heat treatment temperature ranging from about 300° C. to less than 1500° C. for a heat treatment time period ranging from about 20 minutes to about 10 hours to form a precursor to microporous carbon.

Abstract: In an example of the method for making a solid electrolyte interface (SEI) layer on a surface of an electrode, the electrode is exposed to an electrolyte solution in an electrochemical cell. The electrolyte solution includes either i) an organo-polysulfide additive having a formula RSnR′ (n>2), wherein R and R′ are independently selected from a methyl group, an unsaturated chain, a 3-(Trimethoxysilyl)-1-propyl group, or a 4-nitrophenyl group, or ii) a fluorinated organo-polysulfide additive having a formula RSnR′ (n>2), wherein R and R′ can be the same or different, and wherein R and R′ each have a general formula of CxHyF(2x−y+1), where x is at least 1 and y ranges from 0 to 2x. A voltage or a load is applied to the electrochemical cell.
