World's first long-life sodium-ion power bank launched
Japanese hardware brand Elecom has just launched what it claims is the world's first power bank to feature a sodium-ion battery inside. It promises significantly longer cycle life than traditional lithium-ion batteries, as well as the ability to operate in extremely hot and cold climes.
It promises significantly longer cycle life than traditional lithium-ion batteries, as well as the ability to operate in extremely hot and cold climes. On the outside, the affectionately named DE-C55L-9000 looks similar to the vast majority of power banks on the market, with a rounded brick shape housing its 9,000-mAh battery, a 45-W USB Type-C and an 18-W Type-A port, and charging indicator LEDs. The other big draw with this tech is that it has a much longer cycle life – the number of times it can be charged and discharged before the cell's energy density drops – than lithium-ion batteries.
