| Israeli 5-minute Battery Charge Aims to Fire Up Electric Cars |
| 2021-03-08 |
| [ENGLISH.AAWSAT] From flat battery to full charge in just five minutes -- an Israeli start-up has developed technology it says could eliminate the "range anxiety" associated with electric cars. Ultra-fast recharge specialists StoreDot have developed a first-generation lithium-ion battery that can rival the filling time of a standard car at the pump. "We are changing the entire experience of the driver, the problem of 'range anxiety'... that you might get stuck on the highway without energy," StoreDot founder Doron Myersdorf said. The innovation could eliminate the hours required to recharge an electric car, he said. Hundreds of prototypes are being tested by manufacturers. His company, based in Herzliya, near Tel Aviv, is backed by four key investors: German automobile manufacturer Daimler, the UK's British Petroleum and the electronic giants Samsung and TDK. Myersdorf, who set up the company in 2012, has tested the battery on phones, drones and scooters, before tackling the big prize of electric vehicles. But Eric Esperance, an analyst at Roland Berger consulting firm, cautioned that while ultra-fast charging would be a "revolution", many stages remain. "We are still far off from the industrial automotive market," he told AFP. In 2019, the Nobel Chemistry Prize was awarded to John Goodenough of the US, Britannia's Stanley Whittingham and Japan's Akira Yoshino for the invention of lithium-ion batteries. "This lightweight, rechargeable and powerful battery is now used in everything from mobile phones to laptops and electric vehicles," the Royal Swedish Academy of Sciences said on awarding the prize. Myersdorf said charging "speed was not part" of the original design that won the Nobel, so he worked on what was "considered impossible": a lithium-ion battery good to go in minutes. "We wanted to demonstrate that you can take a lithium-ion battery, replace some of its materials and then charge it in five minutes," he said. The engineer switched the original graphite in the battery's negative anode with silicon. "We are taking that amazing innovation of the lithium-ion battery and upgrading it to extreme fast charging capability," he said. Batteries are assembled in a laboratory equipped with large glass boxes, sealed to keep oxygen out. StoreDot chemists clad in goggles and white coats build 100 batteries a week, sent to companies for possible use in their products. The team is already working on a second generation of batteries to cut costs. While the design cycle of a vehicle is "typically four to five years", they are looking to speed up the process. |

| #13 Maybe firing up a 5-minute artillery battery might be better. |

| #12 We had lots of small rodents when I was a child — hamsters and gerbils mostly, with the occasional guinea pig. So the song of the night time exercise wheel is like a lullaby to me. The bicycle one is how my mother and her parents powered the secret radio during WWII. |

| #5 If switching materials results in a cell phone or iPad that can go significantly longer between charges, or charges significantly faster, I’m in. On the other hand, while one of our vehicles is dual fuel, I have absolutely no interest in going all electric, not even if the vehicle carries an easily changed out spare battery and has solar panels on the roof to charge it with. Our current house, apparently at the end of a power line, is too often without electricity for me to be comfortable having no alternatives — even though my exurb has with time become merely a suburb. |

| #4 Glass battery boxes and cars? Yeah I don't see a problem either. Ask Boeing about the steel battery box they had to install in the 787 Screamliner to |

| #3 Do you see those electrical cables coming into the charger *glowing*? That is the energy losses from the required "current density" (amperage) needed to push kilowatts worth of energy quickly into the battery medium... This will require a series of Hi-voltage/Hi-amperage power lines back to the "new and improved" power stations. |

| #2 Great! Um, BTW, where does the electricity come from? |

| #1 Wishful thinking. Young people in cities don't own vehicles, they use rentals. Mass transit is the goal. Costs for most too prohibitive. I see it more likely horse and buggy days will return, especially in rural areas. Service issues alone will be prohibitive. EMS services at wrecks will require special training and tools. Main goal to to prevent individual freedoms to move about at will. |
