Moroccan scientist Rachid Yazami patents innovative battery safety technology
Moroccan scientist Rachid Yazami has achieved a major milestone in battery safety by securing a pivotal patent from the U.S. Patent and Trademark Office (USPTO). This innovative method is designed to detect early signs of internal short circuits in batteries, addressing one of the most pressing risks associated with electric vehicle (EV) technology.
Tackling thermal runaway in EV batteries
The patented system focuses on identifying thermal runaway, a dangerous phenomenon that can lead to catastrophic fires or explosions in EVs. Yazami revealed the breakthrough on social media, explaining how the system conducts real-time analysis of thermodynamic and kinetic data from electrochemical cells. By monitoring parameters like open-circuit voltage, entropy, and enthalpy variations, the technology can detect early indicators of internal short circuits, enabling preventative measures to avert potential disasters.
"This relates to the premature detection of an internal short circuit in a battery, which is the main cause of thermal runaway," Yazami stated, emphasizing the life-saving potential of the invention.
Innovation tailored to global needs
As electric mobility gains momentum worldwide, Yazami’s invention is a significant leap forward in improving EV safety. At the Global Industry 4.0 2023 event in Casablanca, he underscored the importance of adapting batteries to extreme environmental conditions, such as temperatures exceeding 50°C, prevalent in many regions.
The patent, originally filed on May 28, 2019, builds on Yazami’s extensive contributions to energy storage technology. Earlier this year, he was awarded a similar patent in China, also aimed at reducing the risks of fires and explosions in EV batteries. Additionally, Yazami holds a patent for fast-charging technology for lithium batteries, widely used in consumer electronics and EVs.
Supporting Morocco’s green energy transition
Yazami’s work aligns seamlessly with Morocco’s strategic push toward renewable energy and sustainable development. His innovations bolster the country’s commitment to green energy solutions, contributing to global efforts in combating climate change.
Through his groundbreaking research and patents, Yazami continues to strengthen the reliability and safety of battery systems, cementing his role as a pioneer in the field of energy storage.
