Yes and no. They don't market it as "contains electrolytes" like Gatorade does... however if you do your homework electrolytes (at least ones required for basic body functions) include sodium, potassium, chloride, and bicarbonate... extremely common elements/compounds. If you check the ingredients you'll find sodium, sodium chloride, and potassium chloride... all "electrolytes".
If you are looking for electrolytes e-caps/hammer gel sells a number of supplements in pill form (race caps, cardio caps, etc etc) that are likely overkill for most alpine kids but if you are trying to repeat one of Croft's traverses or do the central pillar of swiss in a day car to car they might be a good idea.
For me what I have found works best as keeping me moving is the perpetuem and sustained energy drink mixes... perpetuem is straight up carbs in a drink mix... it tastes and looks like paste dissolved in water (no sugar as sugar hinders preformance for endurance activities)... that shit will keep you cooking for hours on end.
Related to that the hammer gel is one of the most viscous gels I have used... enough that you can easily dissolve it in water (recommended for people who hate gu taste or texture).
