Twaice launches Sodium-ion battery analysis tool

The battery analysis tool just launched by Twaice is a simulation model that enables battery operators to understand the functioning and operation of sodium-ion batteries and optimize them for their intended use.

Using abundant sodium instead of lithium, sodium-ion batteries can offer supply chain, safety and environmental advantages, especially for stationary storage applications where temperatures are lower than in electric vehicles, for example. At 90-150 Wh/kg, sodium-ion batteries have a lower energy than current lithium-ion batteries, but up to 200 Wh/kg is expected in the future.

“As the demand for batteries continues to grow, innovative new options such as sodium-ion batteries are attracting attention. We want to help battery operators better understand how to get the most out of these new batteries,” explains Dr. Michael Baumann, CEO of Twaice.

The new analysis tool from Twaice for sodium-ion batteries offers battery operators the opportunity to maximize the reliability and longevity of both lithium and sodium-ion batteries. The new software also provides researchers and engineers with insights into the characteristics and ageing of sodium-ion batteries.

“Lithium-ion batteries are a proven quantity and we will continue to design our simulation and analytics software to get the best out of lithium storage. At the same time, we want to meet the demand for alternative battery technologies and thus remain a pioneer. We look forward to working with our customers on the application of our new simulation models for sodium-ion batteries,” says Baumann.

In June 2024, Twaice and Nardac – a UK-based insurance broker focused on large energy and infrastructure assets – partnered to enable improved insurance coverage for battery energy storage system (BESS) asset owners, investors, and lenders.

Just a month before, in May 2024, Twaice was part of a US initiative that discovered that faulty installations are often to blame for battery fires. The Electric Power Research Institute (EPRI), the US Department of Energy’s Pacific Northwest National Laboratory (PNNL), and Twaice jointly evaluated 26 battery fires between 2018 and 2023. They say that the diversity of components plays a critical role in igniting fires.

Twaice says its new simulation models will allow operators a better understanding and more effective utilization of sodium-ion batteries. The German company says this should support the development of alternatives to lithium-ion batteries.
