Spain completes testing of Europe’s largest research vanadium BESS
Spain’s Fundación Ciudad de la EnergÃa (Ciuden), a government energy research foundation, has completed operational testing of a 1 MW/8 MWh vanadium redox flow battery (VRFB) system at its Cubillos del Sil technology center, which it says is the largest vanadium flow battery in Europe dedicated to applied research.
New cost-saving copper welding technique for battery cells revealed by Fraunhofer
Resistance projection welding technique could unlock cost-effective copper interconnection potential. Described as a major opportunity for German battery manufacturers, the new approach to copper interconnections will now be used in commercial production.
Scientists demonstrate quantum battery prototype with rapid charging
Scientists from Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO), RMIT University and the University of Melbourne have developed a quantum battery prototype that demonstrates rapid, scalable energy storage using collective quantum effects.
Small 24/7 clean power commitments could cut costs for long-duration storage
TU Berlin researchers say early demand for round-the-clock carbon-free electricity could help bring advanced energy technologies to market faster through technology learning effects. Grant funding for the research was provided by Google, which has since announced plans to build the world’s largest iron-air battery.

LG Chem develops material capable of suppressing thermal runaway in batteries
LG Chem has announced that its Platform Technology R&D team has developed a temperature-responsive Safety Reinforced Layer (SRL), a material which is described as capable of surpressing thermal runaway. The material was analyzed in collaboration with researchers from Pohang University of Science and Technology (POSTECH) in South Korea, while the safety verification was conducted in partnership with LG Energy Solution.
Altech’s sodium chloride solid state battery exceeds expectations
Western Australian battery technology company Altech Batteries has announced its first Cerenergy ABS60 salt-based battery energy storage system prototype is online and operating successfully across a range of temperatures, confirming its thermal stability and commercial viability.
Converting low-cost industrial polymer into zinc-ion battery cathodes
Researchers from the Flinders University of South Australia, in collaboration with Griffith University academics, have used a cheap commercial polymer to develop organic cathodes for aqueous zinc-ion batteries and optimized the battery performance using low-cost additives, as a more sustainable energy storage technology alternative to lithium-ion batteries.

Researchers develop lithium-sulfur battery that can be cut, folded
By coating the iron sulfide cathodes in polymers, a research team was able to create transition-metal sulfide-based lithium batteries with stable cycling and high safety. After 300 cycles, a lithium carbide iron disulfide pouch cell retained 72.0% capacity with no capacity degradation after 100 cycles.
Most home battery storage systems meet warranty claims, new research finds
It took eight years of field measurements for researchers at the RWTH Aachen University in Germany to estimate the usable capacity of home battery energy storage systems and develop a dataset covering 106 system years and 14 billion datapoints. Their key finding was that home battery systems lose about two to three percentage points of usable capacity per year on average, meaning good news for the industry as most warranties in the market can be met with the implementation of capacity reserves.
Aluminium-polymer battery for stationary electricity storage
The device developed by TU Bergakademie Freiberg researchers uses aluminum as an anode, graphite as a cathode, and a polymer-based solid electrolyte. It is being validated and further developed for industrial production. The goal is storage capacity of 10 kWh.
