Next-Gen Sodium Batteries | 25 Apr 2024

Recently, scientists from South Korea have developed next-generation sodium batteries capable of charging in just a few seconds.

These new hybrid sodium-ion batteries combine materials from traditional batteries with those used in supercapacitors.
- These are both cheaper and safer than the conventional lithium-ion batteries found in smartphones and electric cars.
Sodium (Na) is also 500 times more abundant than lithium, while holds the potential for greater charge and efficiency than its Li-ion batteries..
Sodium-ion batteries haven't been widely adopted due to drawbacks like slow charging and low energy storage.
This new battery offers:
- Faster charging times than current lithium-ion batteries.
- Higher energy density than commercial lithium-ion batteries (247 Wh/kg).
- High power density (34,748 W/kg).
Its potential applications include electric vehicles and consumer electronics.
