Key advance in solid battery materials
A team of researchers from the Technical University of Munich (TUM) has developed a New solid driver based on Lithium, antimony and scandiowho has achieved a world record in ionic conductivity. This innovation represents an essential step towards the marketing of safer, efficient and sustainable batteries.
What is special this new material
The material exceeds more than 30 % conductivity of any other compound known so far. The secret lies in his Optimized crystalline structure: By partially replacing lithium with scandio, vacancies are generated in the crystalline network that facilitate the movement of lithium ions. This allows ions to move more quickly, which translates into better battery performance.
Rigorous validation of the results
Given the high conductivity observed, the team collaborated with electrochemical specialists for Confirm the results. The measurements had to adapt because the new compound also conducts electricity, which makes it a Double functional material: It transports both ions and electrons.
-Advantages against previous materials
- Lower chemical complexity: It only requires three elements compared to other materials that need up to six.
- Greater thermal stabilityreducing overheating risks.
- Not flammableeliminating the risk associated with current liquid electrolytes.
- Compatible con existing industrial chemical processeswhich facilitates your scalability.
Opening of a new class of materials
This advance is not limited to a single compound. The discovered principle is applicable to other systemsas those based on Lithium-phosphoruswhich suggests a transformative potential in solid batteries. In addition, this new approach allows exploring simpler and more efficient combinations, without resorting to complex compounds or critical elements difficult to achieve.
Potential
The implementation of this technology can completely transform the way we store energy:
- Increase useful life of batteries reducing degradation.
- Reduces fire risk By eliminating flammable materials.
- Decreases pollutant component dependence or high environmental cost.
- Facilitates mass production Thanks to its compatibility with existing processes.
- Improves the efficiency of renewable systems such as solar panels or wind turbines, allowing safer and dense storage.
This type of innovation is aligned with a cleaner and more safe energy future. Replace liquid batteries with Solid and asbestos solid batteries It represents a strategic step towards a truly green economy.
