Dar dacă în loc să încărcăm bateria de la priză am putea ca la "benzinărie" să schimbăm electrolitul bateriei cu unul deja încărcat și să-l scoatem simultan pe cel uzat din baterie?
Și asta în același interval de timp în care am fi umplut un rezervor de benzină la o mașină clasică?
E posibil?
Da, cu ajutorul bateriilor de tip Redox Flow, care se comportă ca o celulă de combustibl, dar una în care nu se consumă ci se reciclează "combustibilul".

Electrolitul "consumat" din baterie ar fi preluat de "benzinărie" și reîncărcat fie din rețeaua electrică, fie cu turbine de vânt sau panouri solare.
Iată și câteva articole despre proiecte și mașini electrice construite în jurul acestor baterii:

CONCLUSION
Current redox flow batteries can match lead-acid in terms of
energy density but significantly lower than Li-ion systems.
But they have the advantage of rapid charging by electrolyte
replacement which makes them attractive for use on electric
vehicle or hybrid electric vehicles. Golf-cart, forklift truck,
and in-town-short distance family car could find this
beneficial. If infrastructure is in place, long journey distance
would be possible. Another feature of RFBs that makes them
attractive for EV and HEV applications is the separation in
terms of physical location and sizing, of the energy and power
components. This adds a degree of flexibility that allows the
optimization of the power and energy components for specific
vehicle configuration and performance. Further research is
needed to improve the performance and engineering of RFB
system.

Poate va mai dura ani mulți până vom încărca bateriile la pompă, dar este foarte posibil ca acest tip de baterii să devină într-o zi o soluție pentru mașina electrică.
