Everyone knows that battery life on smartphones is generally horrible. It seems we are always trying to find ways to conserve our battery to make it last longer.
Recently, a team at Stanford University designed a new energy source that they hope will one day be able to replace alkaline batteries.
Even though the battery won’t be available to the public anytime soon, it’s still an amazing concept we can get on board with.
Stanford University Professor Hongjie Dai and colleagues have developed the first high-performance aluminum battery that’s fast charging, long lasting and inexpensive. The flexible, non-flammable device produces 2 volts of electricity. The research team was able to generate 5 volts – enough to power a smartphone – using two aluminum batteries and a converter.
In this video, graduate student Ming Gong and postdoctoral scholar Yingpeng Wu demonstrate how the new technology could offer a safe alternative to lithium-ion and other batteries in wide use today.
