-The discharge cutoff voltage should be adjusted such that the formation of DHA dimer, which is unstable chemically, is eliminated until when the regeneration step is initiated. -Combining SOC restriction and regeneration techniques is very effective in further reducing the fade rate. -Choosing a proper cutoff voltage for the regeneration step is critical to maximize recovery efficiency while preventing the decomposition of electroactive species. -The period between the start of successive regeneration events is another important factor affecting the recovery efficiency. Because the energy cost of regeneration is quite negligible, a low period between regeneration events is recommended.
