The genius of the brilliant Moroccan physico-chemist whose age is only sharpening, has no limit as evidenced by his new invention, the fruit of hard work and collaboration with his team in Singapore, where he is currently installed, allowing ultra-fast battery charging and diagnosis of anomalies in terms of battery voltage and temperature during charging.
In fact, Professor Yazami, who confirmed on the occasion of the Forum for the digitalization of the energy transition, Tuesday in Casablanca, that the lithium-ion battery still has good years ahead of it, stressed that this battery must become smarter.
In this regard, he announced that he had found the technology that makes it possible to overcome the constraints linked to energy density, power density, security, performance and battery life, in addition to the environmental aspect and of recycling.
Thanks to this invention, charging will be ultra-fast, which opens the way to improving the performance of electric batteries, especially since the whole world is counting on the replacement of thermal cars by electric cars by 2035 before to extend this technology to other means of transport such as planes and boats.
According to Professor Yazami, the principle is to apply nonlinear voltammetry. For laymen, it is a question of adapting the current of the load to the state of the battery, in other words increasing and decreasing the current according to the level of the battery instead of resorting to linear voltammetry which applies a fixed current.
This technology, which is based on artificial intelligence, makes it possible to charge the batteries ultra quickly while increasing their capacity by 10 to 15 pc.
The ambition of the Moroccan professor did not stop there. Concerned about the safety of users, in particular with the proliferation of cases of fire recorded at the level of electric cars.
He invented the battery scanner. Entropy, a technology that uses artificial intelligence to gather as much information as possible on anomalies observed when charging the battery, which allows this big data to prevent any risk of incident.
In this sense, he used an eloquent metaphor. This technology makes it possible to measure the disorder in the battery in terms of voltage and temperature and through the accumulated data it is possible to solve problems like the doctor who detects a tumor.
The patriot, that he is, said he had a dream, in this case to promote ecological fishing and this, by using solar energy to power fishing boats in Dakhla.
He called on Moroccan skills to take more risks to be able to embark on their own projects, while calling for the federation of the efforts of all stakeholders to achieve more progress and major projects.
