New Li-Ion Batteries Charge 70 Per Cent In 2 Minutes, Last For 20 Years

A team of researchers in Singapore have developed a next generation lithium-ion battery that can recharge a battery to 70 per cent in just two minutes. That means it would charge an entire electric car in just 15 minutes. And here’s the kicker: it lasts over 20 years.

Falling Battery Costs Are The Key To An Electric Future

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.

Scientists Solve The Mystery Of Why Rechargeable Batteries Go Bad

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.

New Lithium Battery Triples Capacity And Charges Fully In 10 Minutes

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.

Boeing Knew About The 787 Dreamliner's Battery Problems Before It Caught Fire

The Boeing 787 Dreamliner was recently grounded across the world because its lithium ion batteries would self-combust in a blaze of glory (aka the batteries melt). What’s interesting is that Boeing knew about all the battery problems in the 787 before any flight was grounded.

Solar Power And Battery Backup: Tesla And SolarCity's Dream Home

Electric car maker Tesla Motors is teaming up with the solar panel leasing company SolarCity to make what might be the first complete, packaged electrical system for an off-the-grid solar home.

Simple Sensor Could Stop Li-On Battery Fires

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.

New Li-Ion Batteries Will Run 10x Longer

While gadgets improve by leaps and bounds every year, the technology that powers them hasn’t. Batteries still suck, unless something comes of this research at Northwestern University that promises new lithium-ion alternatives that charge 10 times faster with 10 times the capacity.

MIT Creates Sun-Free Photovoltaic Power

Oh MIT, we can always count on you to come up with the most clever, little inventions. Just the other day you created goo-powered batteries to replace lithium-ion and now you’ve gone and found a way to make photovoltaic electricity without sunlight!

New Lithium Battery Tech Can Stand The Heat

Li-ion batteries were a massive technological step forward from NiMH cells but were not without faults of their own — like their tendency to explode. A new Lithium-Imide technology from Leyden Energy, however, send lithium-ion the way of NiMH.
