Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

New submitter chaosdivine69 writes: According to Scientists at Nanyang Technology University (NTU), they have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes and have a 20-year lifespan (10,000 charges). The impact of this is potentially a game changer for a lot of industries reliant on lithium ion batteries. In the car industry, for example, consumers would save on costs for battery replacement and manufacturers would save on material construction (the researchers are using a nanotube structure of Titanium dioxide, which is an abundant, cheap, and safe material found in soil). Titanium dioxide is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays. It is believed that charging an electric car can be done in as little as 5 minutes, making it comparable to filling up a tank of gasoline.

    No mention on capacity though. If its capacity is low enough the these claims are easy to achieve.

      And of course, the assumption that if your station's maximum output is 10 MW that you have to have a 10 MW feed to the grid is also wrong. It presumes that you can't have a battery buffer in your station. Look at your typical gas station; pumps spend by far most of their time idle. A charging station with a peak output of 10 MW could probably meet all its needs with a 2 MW feed and a 20-minute battery buffer (although a statistical analysis of consumption patterns would be required for specifics)

  2. 100kW battery makes sense by Roger+W+Moore · · Score: 4, Interesting

    There could be such a thing as a 100kW battery: it would be a battery which can provide a power of 100kW. Not all batteries can do this since they have an internal resistance which either prevents this power from being achieved or will cause them to overheat and explode/catch fire even if it is. Indeed, assuming that this battery can carry a decent amount of energy, it is very likely that you could make a 100kW battery from it since it charges so quickly it must have a very low internal resistance.

    Ironically there is no such thing as a 100kW/hr battery though...

    1 - 2 MW is nothing for a commercial property though. The only reason your house is wired for 100 amps is you would rarely use over 30 - 40. If the demand is there to sell power, the power company will find a way to deliver it to you.

    I design systems with multiple megawatt connections. The last place I was at had 50 MW of service installed to run 5 machines. It was nothing out of the ordinary.

    Getting 250 Amps of 480 3 phase is nothing for a commercial property. That would handily cover your 200KW load.
