It has been a long quest, but the new battery technology that can outperform by 100% the typical ion lithium batteries in your laptop, tablet and smartphone, is here. Solid state electrolyte batteries have been developed by several labs including Sakti3, a start-up which recently received a $15-million investment from Dyson. The new-generation battery fits perfectly in a vacuum cleaner, just as it does in a smartphone… or in a car. The main challenge going forward is manufacturing at scale and commercialization. Patience still remains the name of the game.
