New Sodium Imide Battery Doesn't Overheat, Features 50% More Capacity
One of the biggest hurdles lithium ion batteries face is to overcome is heat. Today's electric cars use complex and bulky cooling systems to get rid of the heat, fact that also lowers the batteries' storage capacity and put weight on the car, lowering its mileage per charge. A new type of battery chemistry that doesn't overheat is now emerging from Leyden Energy's labs.
SolarReserve Receives Funding for CSP & Molten Salt Energy Storage in Nevada
Besides being very pricey, solar power plants simply discourage by the fact that the sun is not always there when you need it: what happens if you need to switch on the light in your kitchen to drink water at 2 A.M. in the morning? Or on a cloudy day, for that matter?... Thanks to SolarReserve and the Obama administration funding it you may never have to go through that.
Company Promises to Develop Battery-Replacing Ultracapacitors in Electric Vehicles
For years, people have been thinking to reduce or even eliminate gasoline-powered vehicles, and switch to battery-powered ones. The the battery-powered electric vehicles' era hasn't already begun well enough, and now some are even thinking to replace batteries with something else: ultracapacitors.
Company Stores Megawatts of Energy In Gravel-Filled Tanks
In a couple of years, utilities will do just about anything to be able to store excess power coming from their future renewable sources, such as wind or solar. The good news is that lately several solutions have emerged from privately-funded startups. One of the solutions found that storing energy inside gravel-filled containers is a good idea, and Isentropic Energy, its creator, is really going to build a prototype.
Researchers Study How Electric Car Batteries Could Get Second Life After Losing Capacity
Officially, car batteries are supposed to have a life span of 8 to 10 years, or at least that's what engineers are trying to achieve. They do have to admit that charge after charge, the battery is not the same any longer: for example, the Chevrolet Volt's battery will probably lose about 60 to 65% of its initial capacity, according to GM.
New Type of Battery Charges From Seas and Oceans and Discharges in Fresh Water
Seas and oceans are often seen profitable for their waves' power, but few know that these huge salt water recipients store energy in yet another way: in their salt. The new approach sees the entire oceans and seas as battery electrolytes. Interesting? Read on.
DBM Energy's Ultra-Fast & Potent EV Battery Independently Verified by German Government
They say that what doesn't kill you makes you stronger - DBM Energy submitted their claims and prototype to German government officials who tested a 68 kWh lithium-metal-polymer battery pack and found out it could carry a car as far as 284 miles (454 kilometers) on one charge.
LG Owns World's Largest Battery Plant for Electric Vehicles
It all stems from South Korea's philosophy on green technologies: they are convinced this is an "unavoidable choice", as President Lee Myung-Bak said during a ceremony. So, with this idea in mind, they set to work: the LG Chem Company has just announced in Seoul that it now owns the world's largest battery plant for electric cars.
CryoEnergy System Stores Peak Energy Into Liquid Air
The CryoEnergy System uses air comprised in refrigeration units and exposed to the extreme temperature of -196 °C. The resulted liquid air is then kept in an insulated tank, whose ambient pressure doesn't exceed 1 bar.
Illinois Researchers Create 3D Battery Electrode That Could Make EVs Charge In Minutes
The big problem with nowadays' batteries is that they charge and discharge slowly. They can be made to charge and discharge faster at the price of their shortened lifetime, but that's not a solution at all. Supercapacitors may offer fast charge/discharge rates, but their capacity is just not very high. A hybrid of these two would be perfect.
