A team of scientists from China and Australia has found a way to improve sodium-sulfur batteries.
The developed batteries use carbon-based electrodes and a thermal decomposition process to change the reaction between sodium and sulfur. This made it possible to increase the capacity of the batteries and extend their service life, which sodium-sulfur batteries could not boast of.
The result is a battery with a capacity of 1017 mAh/g at room temperature, four times that of a lithium-ion battery. The sodium-sulfur battery retained about half of this capacity after 1000 recharge cycles. The team is pleased with the result but will not stop there.
This is a significant breakthrough in the development of renewable energy, which, while reducing costs in the long run, has several financial barriers to entry.
