South Korean Scientists Unveil Breakthrough in Lithium Battery Technology
Du South Korean scientists have revealed the latest research in lithium battery technology. The new lithium battery developed by researchers in South Korea could bring up an increase in mileage for electric vehicles and can also lower the chances of incurring a fire accident. This technology, which has been developed by scientists from POSTECH University, reveals a new approach to its lithium-ion movement controlling process.
Performance Neoteric Breakthroughs and Key Metrics
The new battery system exhibits phenomenal performance enhancement as against the current technology.
- Specific Capacity: The battery renders a specific capacity of 1,400 mAh/g, which is about four times larger than state-of-the-art graphite anodes.
- Efficiency and Durability: It has maintained a Coulombic efficiency of more than 99% for more than 300 charge-discharge cycles, indicating a high degree of reversibility and stability.
How It Derived Technology
Innovation encompasses a ferromagnetic anode constituted with manganese ferrite. An external magnetic field has been applied to this battery which under Lorentz force specified controls the mobility of lithium ions. This guarantees a well-defined deposition of lithium onto the anode thus generating a stable layer.
This is a very critical technique as it avoids the formation of dendrites. Dendrites are needle-like spike structures formed by lithium during charging, and grow long enough to short-circuit on anything within reach, creating overheating and potentially fire. This has made personal ion deposition with all-new technology possible and safe capacitance and safety under extreme loading.
Impact on Electric Vehicles
This directly meets two of the greatest challenges in electric vehicles today; massively high energy density could mean a long driving range for much more electric vehicles, while dendrite-generated short circuits would promise a much safer and more reliable battery that is less prone to thermal events.
