Lithium chemistry is preferred for long-life applications because its intrinsic negative potential exceeds that of all other metals. Lithium is the lightest non-gaseous metal, offering the highest specific energy (energy per unit weight) and energy density (energy per unit volume) of all available battery chemistries.
Most cottages in the countryside are heated by burning wood in a simple stone hearth. The desired heat is controlled by the feeding of wood. Today computers manage heating systems in large buildings and the boiler has become almost secondary. A similar trend is evolving with batteries.
