One promising flow battery type is called a vanadium redox battery, and the way it works sheds some light on why these batteries can last so long.
You're not going to get the same type of battery life you see out of smaller devices, but for one of this type, it's pretty solid.
This type of battery has an unusually high energy density, which means the units can be smaller and thus lighter for a given amount of power than traditional batteries.
The Tesla Model S is a plug-in electric luxury sedan than can travel between 160 and 300 miles on a single charge, depending on the type of battery chosen.
Unlike in most batteries, where one chemical turns into another chemical as it releases or stores charge, the vanadium in this type of battery simply takes on or releases electrons.

There's intrigue in this type of charging because as long as you have the proper sleeve or battery cover attached, you can easily charge your gizmo just by placing it on a compatible pad.
Khare's device, a black, rectangular type of supercapacitor just over an inch long, can charge a cell phone battery in 20 to 30 seconds, she said.
Battery life is seven hours, with 200-hours of standby, which is about the norm for this type of kit.
Plug-in hybrids remain the type of electrified vehicle that makes the most sense because they release the driver from dependence only on a battery-fed powertrain.
