With an electrolytic solution the consumer returns the spent electrolyte to the "filling station" where it is recharged by local power generation or by the national electricity grid. It is enough to pump the spent electrolyte and pump in literally freshly charged electrolyte, liquid electricity. The discharged liquid is also reusable: it can be recharged and then pumped to another vehicle, making it an environmentally friendly solution. Researchers at MIT have named their new semisolid flow cell design battery. The battery stores electrical energy as a liquid called Cambridge Crude. When the energy in the liquid is exhausted, all users have to do is go to a charging station to pump the old liquid and pump it into a new batch of fully charged liquid. The recharge of this liquid will be carried out in the recharging station with a special recharge equipment that will be part of the general system. Liquid electricity takes the form of a vanadium redox battery technology. We can change the electrolyte in this type of batteries.
