Electric car news
The security of electric vehicles takes another major step forward with an innovation that could put an end to rare but spectacular battery incidents. South Korean researchers have just developed a promising technology that combines high performance and maximum security.
A major innovation in battery chemistry
The DGIST institute (Daegu Gyeongbuk Institute of Science and Technology) has developed a lithium metal battery incorporating a triple-layer solid polymer electrolyte. This unique architecture not only improves performance, but above all introduces a self-extinguishing function in the event of a thermal incident. The results are particularly impressive with a 88% capacity retention after 1000 charge-discharge cycles.
An answer to security concerns
Statistics show that electric car fires are significantly less frequent than those of thermal vehicles. Here are some key figures:
- 1 fire for 1250 electric vehicles versus 1 for 200 thermal vehicles
- Average response time to a battery fire: 2 to 3 hours
- Temperature reached during thermal runaway: up to 2000°C
A technology applicable on a large scale
Dr. Kim Jae-hyun, principal investigator of the study, envisions multiple applications for this innovation. The technology could equip both smartphones and large-scale energy storage systems. The giant LG Energy Solution is working in parallel on a reinforced security layer sensitive to temperature, acting as a preventive fuse.
Impact on the electric automobile industry
This technological advance comes at the right time in a context of exponential growth in the electric car market. Here is an overview of the projections:
| Year | Estimated market share | Production volume |
|---|---|---|
| 2023 | 14% | 10 million units |
| 2025 | 23% | 20 million units |
| 2030 | 40% | 35 million units |
This South Korean innovation marks a decisive step in the democratization of electric vehicles. Self-extinguishing technology directly addresses consumer concerns while improving overall battery performance. Car manufacturers are following these developments carefully, aware of the crucial importance of safety in the mass adoption of electric mobility.
-The next few months will be decisive for the marketing phase. The first full-scale tests will validate this promising technology which could redefine security standards in the sector. Drivers can calmly consider their transition to electric, supported by these major technological advances.
