Thanks to QUT, Australia's first facility to produce commercial grade lithium-ion batteries is up and running.

It is the only place in the country capable of making the batteries - which are in the same format as those used to power Tesla cars - because of it's low humidity electro-manufacturing dry rooms.

This week's edition of Batteries Are Dangerous brings us to the great state of New Jersey, where a Bluetooth speaker recently started burning on a girl's bed and then exploded. Thankfully, nobody was hurt, and the house didn't burn down. The incident still serves as a cautionary tale for us all.

Battery storage is one particular technology that isn't advancing as fast as we want. Despite all the promises of graphene and carbon nanotubes, batteries for long-term and high-demand energy storage are falling in cost largely thanks to improvements in the development of good ol' fashioned lithium-ion cells. There's one particular dollar figure where batteries (and the renewable energy sources that go hand in hand with them) beat out fossil fuels, and one number where they'd be far and away the best electricity delivery technology.

Every time you recharge your lithium-ion batteries, their storage capacity decreases just a little bit. That is why your mobile gadgets won't stay on nearly as long as they did even a year ago. Thanks to research by the US Department of Energy, we finally know why exactly that occurs and, more importantly, how to stop it from happening.

The number one technological hurdle separating humanity from the Jetson Future we deserve is developing a reliable power supply. Even today, we're barely even able to keep out phones alive through the evening commute. But a radical departure in Lithium ion battery technology could help keep our power-hungry gadgets online for days, not hours.

Li-on batteries feature in most of the mobile electronics we use because they pack far higher energy density than their competitors. But until now there have been a whole heap of problems with those same batteries overheating, and even catching on fire.
