Seonglae ChoScientists developed a lithium-air battery with record-breaking energy density
A team of researchers from Japan's National Institute for Materials Science (NIMS), backed by Japanese conglomerate SoftBank, has developed a lithium-air battery with a record-breaking energy density of more than 500 watt-hours per kilogram (Wh/kg). To put that into perspective, the novel battery has nearly double the energy density of the battery used in a Tesla Model 3.

New battery seems to offer it all: Lithium-metal/lithium-air electrodes
Current lithium batteries are based on intercalation-lithium ions squeeze into spaces within electrode materials such as graphite. As a result, most of the battery's volume and bulk is dedicated to things that don't contribute to carrying charges between the electrodes, which sets a limit on the sorts of energy densities that these technologies can reach.
