Soluna unveils 20kWh battery for residential and commercial applications
The Chinese manufacturer says the battery has a depth of discharge of 95%. It will be available for sale starting from Q1 2022.
Redox flow battery with capacity retention of 99.98% per cycle
The battery was fabricated by Chinese scientists with a low-cost electrolyte made of a derivative of TEMPO, which is a well-known electroactive aminoxyl radical used with several applications in chemistry and biochemistry. According to the researchers, the battery shows high redox potential and is crossover-free.
Australia’s hottest town now has a battery to store its excess solar
The town of Marble Bar in Western Australia’s remote East Pilbara region is famed for at one time recording 100 consecutive days of temperatures exceeding 37 C. So it’s no wonder the town’s residents have excess solar and nowhere to put it. That is, until now, thanks to the installation of a battery energy storage system beside the town’s centralized solar farm.
