Israeli start-up company is developing just a few minutes full of electric vehicle batteries

Israeli startup StoreDot is developing a battery that only needs to be charged for 5 minutes，Fast-charging batteries that can drive electric cars hundreds of miles。

Tesla's fast charger can fully charge the car battery for 170 miles in half an hour。But if an Israeli startup achieves their goal，Only need to charge for 5 minutes，Electric cars can travel hundreds of miles。

last Wednesday，StoreDot, a three-year-old startup, announced，They are from the investment department of South Korean electronics giant Samsung Group and Russian investor Roman?Abramovich raised $18 million。The company has raised a total of US$66 million so far，They plan to use the latest financing，Promote the application of its fast-charging batteries in electric vehicles。

Many companies are trying to improve the battery life of electric vehicles in various ways。Companies like Tesla and Panasonic are focusing on making devices that store more energy on a single charge、Batteries that consume less power。other companies，Such as the now-defunct Israeli startup Better Place，trying to build a site with a robotic arm，They can quickly remove the battery on the car，and replace it with a fully charged battery。Others are building networks of charging stations in parking lots in shopping centers or office areas，for the driver to recharge when necessary。

Anything that makes electric cars more competitive with gas cars，Technology that is even better than gasoline cars，can be regarded as a major innovation of great value。The battery is the most expensive part of an electric car，Can travel up to 265 miles on a single charge。Charge with a standard charger，It Takes Hours to Fill These Top-Rated Batteries。Even with a much more expensive fast charger，The so-called DC charger，It also takes more than 30 minutes to fully charge。

Consumers are worried about the inconvenience and slow charging speed，is one of the reasons why electric vehicles have not been widely adopted。A total of 16.5 million new cars were sold in the U.S. last year，Electric car sales were only 118,000。

StoreDot was founded in 2012，They're trying to solve the battery problem in a very unique way。The company developed a new lithium-ion battery，It is said to be fully charged in minutes。Theoretically speaking，so，Charging an electric car is as easy and quick as refueling at a petrol station。

The company and its team of scientists used nanotechnology to produce new organic materials，Batteries made of it charge and discharge much faster than ordinary lithium-ion batteries。They have 50 employees，Including 20 researchers with Ph.D.。

The first problem with standard lithium-ion batteries is that several factors—including the materials used in the battery and the design of the battery—can block the flow of electricity inside the battery，Transferring energy is therefore more difficult。This is the so-called "resistance" inside the battery。

StoreDot is optimized for battery，reduce its resistance as much as possible。They exploit molecular-level processes，Electrodes used for charging and discharging are made very thin using new materials。chief executive doron?meersdorf claims，The electrode layer is so thin that it is "almost transparent"。This design helps reduce resistance，Allows current to flow rapidly through the battery within minutes。

The startup is currently working with a number of major mobile phone manufacturers，Test this battery on your phone。Meersdorf said，He expects to sign a commercial contract with a smartphone maker within "two to three quarters"，and put this battery in a phone sometime next year。

However, it will take longer for such batteries to be used in electric vehicles.。StoreDot uses raised funds to build a division，Specializes in how to convert the company's mobile phone batteries into electric car batteries。even if everything goes well，StoreDot's batteries won't be used in commercial electric vehicles for at least five years。

But as all battery startups can attest，A lot of things can go wrong along the way。Bringing battery technology from the lab to the commercial market is difficult，It remains to be seen whether automakers are interested in the untapped battery.。

Other startups working on new EV batteries include Sakti3、QuantumScape、Seeo、XG Sciences、Envia Systems和SolidEnergy Systems。According to data from research firm Lux Research，Panasonic has a 39% market share in the EV battery market，LG Chem and Samsung SDI are also big players in the field。
