A joint team of US and Korean researchers have developed a new type of microbattery designed for use with microdevices. They achieved this by foregoing standard packaging to reduce size and making the entire battery hermetically-sealed, fully-dense and stackable.

So far the batteries come in 3 stackable variations, single- (∼4V), double- (∼8V), and triple-stacked (∼12V) configurations with energy densities reaching 990 Wh/Kg and 1,929 Wh/L.
