Researchers have invented a new battery that they claim could have profound implications for the future of energy storage and renewable technologies. The lithium-based redox-flow battery, developed by a team at the University of Cincinnati, could prove crucial for wind and solar operations, where large-scale batteries are needed to store energy during times of overproduction and release it when production drops off. “Energy generation and energy consumption is always mismatched,” said Jimmy Jiang, who led the research at the University of Cincinnati. “That’s why it’s important to have a device that can store that energy temporarily and release it when it’s needed.” The novel design removes the membrane that separates the positive and negative sides of the battery, which is one of the most expensive parts of this type of battery and has previously hindered development. The membrane-free battery exhibited high voltage and energy density that could potentially meet the demands of large-scale green energy operations at an economically viable cost for the first time. “This design significantly decreases material costs,” said Soumalya Sinha, a visiting professor at the University of Cincinnati who was involved in the research. “We’re trying to achieve the same performance at a cheaper cost.” The team has submitted patent applications for the design, which Dr Jiang said will herald a “battery revolution” within the next 20 years. “I am confident about that,” he said. “There is a lot of intense research going into pushing the boundaries of battery performance.” The research was detailed in a paper, titled ‘Development of high-voltage and high-energy membrane-free nonaqueous lithium-based organic redox flow batteries’, published in the journal Nature Communications.

One police officer was killed and two others sustained injuries after a gunman opened fire on a busy street in Fargo in North Dakota, authorities said. The suspect was killed on Friday, the police said, adding that a civilian was also injured during the incident. Witnesses reported seeing a man opening fire on police officers on a busy street before other officers shot him. Shannon Nichole was driving in that area at that time when "shots were fired" and she "saw cops go down". "My airbag went off and the bullet went through my driver's door," she told KFGO Radio. A man grabbed her and told her they needed to get out of the area, she recalled. Authorities said there was no threat to the public but officers converged on a residential area about two miles away and evacuated residents as they gathered evidence related to the incident. Chenoa Peterson said she was driving with her 22-year-old daughter when a man pulled out a gun and began firing at police. "He proceeds to aim it and you just hear the bullets go off, and I'm like, 'Oh, my God! He's shooting!’" she told The Associated Press. Ms Peterson's first instinct was to pull over and try to help, she said, but her daughter convinced her to leave. "It's weird knowing that if you were 10 seconds earlier you could have been in that," she added. A surveillance video provided by resident Allison Carlson captured the sound of gunfire. North Dakota attorney general Drew Wrigley said the state Bureau of Criminal Investigation is working with law enforcement agencies in response to a "shooting incident", without providing further details. Police and other local agencies across the region posted their sympathies for Fargo police on social media. "Thinking of our brothers and sisters in Fargo," read a post from the South Dakota Fraternal Order of Police. The Fargo police department said it plans to release more details later on Saturday.
