> Inexpensive New Liquid Battery Could Replace $10,000 Lithium Systems

Engineers have created a new water-based battery designed to make rooftop solar storage in Australian homes safer, more affordable, and more efficient.

This next-generation “flow battery” paves the way for compact, high-performance energy systems suitable for households and is projected to cost far less than today’s lithium-ion setups, which are priced around $10,000.

Although flow batteries have existed for decades, they have mostly been limited to large-scale energy storage because of their bulk and relatively slow charging times.

Wanqiao Liang, the study’s lead author and a PhD candidate in the Department of Materials Science and Engineering, explained that the team’s redesigned membrane solves this speed limitation, making the technology practical for homes and positioning it as a strong contender in the renewable energy market.
