Collaboration with Indian Association for the Cultivation of Science (IACS)
and S. N. Bose National Centre for Basic Sciences (SNBNCBS), scientists
have developed a porous organic anode material based on a Covalent Organic
Framework (COF) that enables ultrafast charging and high durability in
rechargeable batteries in the near future.
Highlights:
1.
Developed a porous organic anode using Covalent
Organic Framework (COF) technology.
2.
Allows rapid movement of lithium ions, reducing
charging time significantly.
3.
The battery achieved 80% charge in just over
one minute.
4.
Maintained excellent cycling stability over
repeated charge-discharge cycles.
5.
Also demonstrated the ability to store sodium ions,
indicating potential for sodium-ion batteries.
6.
Successfully tested in a practical battery device,
showing real-world applicability.
7.
Covalent
Organic Framework (COF):
i.
COFs are highly porous, crystalline organic
materials made by linking light elements (C, H, O, N, B, etc.) through strong
covalent bonds.
ii.
Their ordered nanoporous structure provides:
a)
Large surface area.
b)
Fast ion transport pathways.
c)
High structural stability.
d) Tunable chemical
properties.
8.
Significance:
i.
Supports the growing demand for Electric Vehicles
(EVs).
ii.
Enables faster charging for smartphones,
laptops, and portable electronics.
iii.
Improves storage solutions for renewable energy
such as solar and wind.
iv.
Reduces charging downtime while improving battery safety
and durability.
v.
Strengthens India's research capabilities in
advanced battery technologies.
9.
Challenges:
i.
Scaling up laboratory synthesis for mass production.
ii.
Cost-effective manufacturing of Covalent Organic
Framework (COF) materials.
iii.
Long-term commercial validation under varied
operating conditions.
iv.
Integration with existing battery manufacturing processes.
