Research at the University of Cordoba shows the potential of calcium to be a component of batteries in the future at an theoretical and experimental level, due to it polluting less and its plentiful supply
One possible solution to pollution in cities from combustion engines is the use of electric vehicles. Currently lithium ion batteries are the most commonly used in electric vehicles. However, they are not free from problems. Foreseeably, lithium resources will be insufficient to cover the battery market in the future. In addition, lithium batteries are not as safe as can be and they contain toxic components that are environmentally damaging.
