Dr. Rachid Yazami, best known for inventing a graphite anode for use inside lithium-ion batteries, said he has developed technology that can charge electric vehicles in just 10 minutes.
We have developed a new technology that is the fastest battery charging technology in the world. We recently completed charging a high density battery in ten minutes. Compared to Tesla, which charges in 70 minutes, we are seven times faster.
To do this, Yazami uses a method called Non-Linear Voltammetry (NLV), which regulates the voltage at different levels. If you think of these levels as steps, then at a certain step, the required voltage will remain constant until you reach a higher step. Thereafter, the voltage is changed to a suitable value required for the new stage. The process continues and eventually the battery is fully charged when the process reaches its maximum level.
Yazami believes that this method helps “make the battery happy” and increases the charging speed and also improves the stability of the battery. Ultimately, Rashid Yazami hopes that 10 minutes of charging an electric car will be enough for 800 kilometers.
Earlier this year, Extreme Fast Charging (or XFC) battery company StoreDot announced that it has released a next-generation car battery that can charge a two-wheeled electric vehicle in just five minutes.
