Penn State to Improve Li-Ion Battery Safety

Samantha Joe — Fri, 08 Jan 2016 17:40:51 +0000

Part of a battery getting better means getting safer. Scientists at Penn State’s Battery and Energy Storage Technology (BEST) Center have been working on improvements in li-ion battery safety. They have inserted sensors that would warn users to potential internal problems. Li-ion batteries are common, as they are light, small, and provide more energy, relative […]

How “The Hybrid Shop” Reduces Hybrid Battery Waste

When considering a hybrid vehicle, perhaps one of the first things you think about is fuel economy. Then there’s the hybrid battery, which will eventually fail, and do you have any idea how much that costs? The thing about hybrid battery packs isn’t “if” they’ll fail, but “when” they’ll fail. For the most part, dealerships […]

Genovation Cars is still kicking, although I did have to look them up because I’d never heard of them until now, and has partnered with University of Maryland to develop new hybrid electric-vehicle battery technology. There are plenty of electric vehicle battery companies out there, working on the next best thing for electric vehicles. The […]

In the last few years, electrified, zero emissions buses have become, if not common, at least accepted in cities around the world. One bus line in Milton Keynes, UK, runs a fleet of electric buses that recharge on the driver’s break via an inductive charging pad buried in the road. One limitation of the electric […]

New Korean Li-Ion Battery Lasting 8 Times More

Ovidiu Sandru — Mon, 17 Nov 2008 19:33:51 +0000

South Korean professor Jaephil Cho (and, of course, a team of his students) from Hanyung University have developed a lithium-ion battery that lasts eight times longer than the actual models do.
Quantumsphere, on the other hand, presented last september a Li-Ion battery with a new that lasts five times more than traditional ones.

EnerDel to Make Longer Lasting, Cheaper Li-Ion Batteries by 2010

Ovidiu Sandru — Mon, 09 Jun 2008 09:45:12 +0000

EnerDel, a company who has been on the market since 2004, makes serious promises about more efficient lithium-Ion batteries (LIB) to be manufactured in the very near future. They're planning to make 300,000 of them by 2010. They also say that their batteries keep their charge capacity for up to 300,000 cycles, or 10 years of life.

Home Made Electric Bike

Ovidiu Sandru — Wed, 16 Apr 2008 06:41:37 +0000

Here’s a short video of someone who modified his bicycle to go electric. He used a brushless motor and a pack of several Li-Ion batteries of 36V capable of 30A (about 1kW). You’ll, see, he uses two, four, six, or eight of these batteries. That’s 8kW = about 5hp. That’s more than a regular motoscooter […]

Green Batteries: past, present, future

Ovidiu Sandru — Sat, 02 Feb 2008 14:25:05 +0000

In life it’s always good to have a back-up plan, an alternative course of action in case the primary one goes sour. The same could be said for developing batteries. Leading the race in high-tech battery technology are variations of lithium ion. Lithium is the lightest solid element on the planet and is suitable for […]
