May 2013 : Cold fusion reactor independently verified, has 10,000 times the energy density of gas. Against all probability, a device that purports to use cold fusion to generate vast amounts of power has been verified by a panel of independent scientists.

Faraday Future unveils 'world's highest energy density' EV battery

Folding batteries increases their areal energy density by up to 14 times. By folding a paper-based Li-ion battery in a Miura-ori pattern (similar to how some maps are folded), scientists have shown that the battery exhibits a 14x increase in areal energy density and capacity due to its smaller footprint.

Sodium-ion battery cathode has highest energy density to date. —Although sodium-ion (Na-ion) batteries don't perform as well as lithium-ion (Li-ion) batteries, they have the potential to be a cheaper alternative. In a new study, scientists have designed a new cathode for Na-ion batteries that provides an energy density of 600 Wh kg-1, which is the highest reported so far for Na-ion batteries and even rivals the energy densities of some Li-ion batteries.
