"avoids copper, aluminium or steel to evacuate electrical current, and also tabs (current terminals) made of nickel or other metals, that conventional batteries use... reduces weight and volume, increases energy density between 30% and 60%, and eliminates risk of explosion or fire... without need to replace current cell assembly machinery... can be used with lithium or sodium, opening new field in silicon batteries, supercapacitors, fuel cells and hydrogen electrolyzers"
