A sodium-ion battery that charges to 80% in 15 minutes
The Chinese company CATL will market a sodium-ion battery in 2023 that can be charged to 80% in 15 minutes. It is said to have a density
It could operate at low temperatures as it is capable of maintaining 90% capacity below -20°C. It could operate at low temperatures as it is capable of maintaining 90% capacity below -20°C. Its electrodes are mainly made of salt, which provides additional raw material storage space compared to the lithium battery, and costs less. On the other hand, the sodium ions are larger and prone to impurities, resulting in a shorter lifetime. CATL uses porous carbon for the anode and a material called Prussian white for the cathode.
