Rabat – Moroccan scientist Rachid Yazami has received a new patent in China for the safety feature he developed to prevent internal short circuits in electric vehicle (EV) batteries.
Yazami announced the news today on his social media, saying: “Chinese patents follow one another and are not alike!”
“Delighted to announce a new patent granted by China this time on the safety of batteries related to the appearance of an internal short circuit in the battery which remains the main cause of the ignition and explosion of the latter,” the post reads.
The Moroccan scientist says that this technological advancement will contribute to making electric cars safer and avoid accidents that could cause injuries or death. The patent was originally filed in May of 2019.
On the sidelines of the Global Industry 4.0 2023 event in Casablanca, Yazami spoke to Morocco World News about his work and the urgent need to address safety concerns in electric batteries.
He said that batteries need to be tailored to the market’s unique environmental conditions, where temperatures can reach over 50 degrees Celsius.
Yazami then told MWN about his project aimed at enhancing the stability of lithium-ion batteries to allow them to function reliably even in scorching heat.
“I’m currently working on a project to increase the stability of lithium batteries up to 90 degrees Celsius…and this is another big technological and scientific challenge,” he said.
This achievement marks Yazami’s second patent from China for lithium battery technology.
The Moroccan researcher received his first patent from China for his EV battery fast-charging technique in December.
In February of 2024, Yazami received his first patent in Japan for this same technology. His invention facilitates faster charging for lithium batteries used in both electronic devices and electric vehicles.
Yazami’s breakthroughs come at a crucial time when Morocco is rapidly expanding its footprint not only in the electric vehicle industry but also renewable energy as the world is trying to rapidly adapt to the damaging effects of climate change.
