Is this what the electric car dreamers have been waiting for? Power Japan Plus is to mass-produce this year "Ryden," a disruptive carbon battery that can be charged 20 times faster than an ordinary lithium-ion cell.
The battery, said to cheap to manufacture, safe, and environmentally friendly, could massively improve the range and charging times of electric cars, Gizmag reports. The range it is said could be a staggering 300 miles .
The new battery developed by Power Japan and Kyushu University is described by researchers as "dual carbon" since both electrodes are made out of carbon. They claim that their design not only has high energy density, but is also economical, very safe, reliable, and environmentally sustainable. Most importantly, it can charge 20x faster than its Li-ion counterpart.
According to the company, their technology would allow you to charge the battery of a Nissan Leaf in 12 minutes instead of four hours. There would be a charging time of 42 minutes for the 85 kWh battery of a top of the line Tesla Model S.
Power Japan also claims that their battery has energy density comparable to state of the art lithium-ion, with manufacturing costs that are equal or lower. This is because carbon, which is widely available in nature, is the only active ingredient, and the batteries can fit into a standard 18650 cell (the one used in laptops and electric cars), requiring no significant change to existing manufacturing lines.
The battery has a long lifetime of 3,000 charge/discharge cycles (Li-ion's life is closer to 1,000 cycles) . It can also discharge fully without the risk of short-circuiting and damaging the battery. The battery doesn't heat up, so it wouldn't require the extensive cooling systems that appear in current electric cars. Thermal stability also makes the battery much safer, because it eliminates the risk of thermal runaway, which can cause explosions. And it would be more powerful than other batteries, operating at over four volts.
The battery is fully recyclable. Power Japan is planning to produce the battery using an organic carbon complex, developed in-house from organic cotton, to obtain a greater control over the size of the carbon crystals in its electrodes.
Power Japan is planning to start production of 18650 dual carbon cells later this year for specialty applications such as medical devices and satellites. They plan to license the technology to other companies for use in electric vehicles.
It has to be said there is an air of disbelief in some of the comments:
martinkopplow says," This is a laboratory sample, while all the EV manufacturers have already secured long term contracts with 'classic' Li-Ion suppliers, so there is still a long piece of road ahead until a new tech like this will make it to the streets.
Still I think this is an exciting development worth watching. I hope they become available when the battery pack currently in my electric car will be about to die."
The video is very matter-of-fact, Watch it - and you decide.
