Lithium-metal battery with capacity retention of 88% over 1,000 cycles
German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.
Lithium-sulfur battery with shorter charging time, longer lifespan
Japanese scientists have developed a new lithium-sulfur battery by using titanium oxide and titanium nitride to prevent the formation of polysulfides during the fabrication process. This allows the battery to retain 85% of its capacity after 500 cycles at 2 C.
Australia to host 600 MW/2400 MWh storage facility
Renewables developer Syncline Energy has revealed plans for a 600 MW/2400 MWh battery storage project near Melbourne.
Data confirm the rise of solar-plus-storage hybrids across the U.S. grid
Battery prices are falling, and renewable energy generation continues to expand, leading power plant developers to co-locate energy storage along with power generation assets.
Multi-day iron-air batteries reach commercialization
US-based startup Form Energy has secured $200 million Series D funding for the development of what is being called a breakthrough in energy storage.
Sandia researchers develop new grid-scale energy storage battery
The battery operates at 230 degrees Fahrenheit, opening what researchers said could be “a whole cascading cost savings” including everything from less expensive materials to less insulation.
Fire at Australian big battery
Speculation will be rife as to the cause of the fire which destroyed one Tesla Megapack and damaged another in Moorabool on Friday. Investigators are waiting until the site is deemed safe to begin their forensic examination.
