Ankara Breakthrough New Energy Battery Technology

What is battery technology?

The battery technology is designed to be used in smaller-sized cells, replacing existing coin-shaped batteries found in watches and other small electronics.

Can K-Na/S batteries save energy?

In a new study recently published by Nature Communications, the team used K-Na/S batteries that combine inexpensive, readily-found elements — potassium (K) and sodium (Na), together with sulfur (S) — to create a low-cost, high-energy solution for long-duration energy storage.

Can acetamide and -caprolactam improve batteries?

Previous studies have struggled with solid precipitates and low capacity and the search has been on for a new technique to improve these types of batteries. Yang’s group developed a new electrolyte, a solvent of acetamide and ε-caprolactam, to help the battery store and release energy.

Could a new energy source make batteries more powerful?

Columbia Engineers have developed a new, more powerful “fuel” for batteries—an electrolyte that is not only longer-lasting but also cheaper to produce. Renewable energy sources like wind and solar are essential for the future of our planet, but they face a major hurdle: they don’t consistently generate power when demand is high.

What is a K-Na/s battery?

Columbia Engineering scientists are advancing renewable energy storage by developing cost-effective K-Na/S batteries that utilize common materials to store energy more efficiently, aiming to stabilize energy supply from intermittent renewable sources.

What are the problems with K-Na/S batteries?

There are two major challenges with K-Na/S batteries: they have a low capacity because the formation of inactive solid K2S2 and K2S blocks the diffusion process and their operation requires very high temperatures (>250 oC) that need complex thermal management, thus increasing the cost of the process.
