Applications lead acid, secondary’ electric vehicle

The largest asset of lead-acid batteries is their low price, compared to any other secondary battery currently available. The energy density is inherently low, but in its main application as a car battery this is tolerable. For application as the main power source of electric vehicles, an energy density of at least 100 W h/kg is necessary. This corresponds to 58% of the theoretical energy density - a very difficult goal. Power density is another limitation, particularly since increasing the power decreases the energy density substantially.
