Columbia EK energy storage battery new product

Can K-Na/S batteries store energy?

A new study published in Nature Communications demonstrates that K-Na/S batteries can store energy using inexpensive and readily-found elements: potassium (K), sodium (Na), and sulfur (S). This creates a low-cost, high-energy solution for long-duration energy storage.

What are K-Na/s batteries?

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

What is the Columbia Electrochemical Energy Center?

The Columbia Electrochemical Energy Center (CEEC) is using a multiscale approach to discover groundbreaking technology and accelerate commercialization. CEEC joins together faculty and researchers from across the School of Engineering and Applied Sciences who study electrochemical energy with interests ranging from electrons to devices to systems.

Can K-Na/S batteries save energy?

In a new study published September 5 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.

Are flow batteries the future of energy storage?

Both batteries and dense energy carriers have attracted vast research efforts as options for large-scale energy storage. With high scalability potential and long discharge times, flow batteries, where energy is stored in the form of redox active species, can be promising.

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.
