Newswise: Using AI to develop hydrogen fuel cell catalysts more efficiently and economically. “The team developed Slab Graph Convolutional Neural Network (SGCNN) artificial intelligence model to accurately predict the binding energy of adsorbates on the catalyst surface. This is not the first application of AI to materials discovery. The SGCNN model was developed by evolving the CGCNN model, which is specialized in predicting bulk properties of solid materials, to predict surface properties of catalytic materials.”

Dalhousie University: Dal researchers’ chance discovery could help extend battery life by replacing tape that causes self‑discharge

Dalhousie University: Dal researchers’ chance discovery could help extend battery life by replacing tape that causes self‑discharge. ‘”In commercial battery cells there is tape — like Scotch tape — that holds the electrodes together and there is a chemical decomposition of this tape, which creates a molecule that leads to the self-discharge,” says Michael Metzger, an assistant professor and the Herzberg-Dahn chair and in the Department of Physics and Atmospheric Science.’

IDW: Battery research – First online database on photocharged materials developed. “Dr. Aleksandr Savateev, group leader at the Max Planck Institute of Colloids and Interfaces, has developed a unique online database. To do so, he has analyzed and standardized research data from 300 papers published over the past forty years in the field of photocharged semiconductors. The database could be used to find suitable photosemiconductors for designing new batteries, rechargeable batteries and supercapacitors more quickly and in a more targeted manner.”

National Renewable Energy Laboratory: Battery Policies and Incentives Database Contributes to U.S. Efforts To Build a Secure Electric Vehicle Battery Supply Chain. “The U.S. Department of Energy’s (DOE’s) new Battery Policies and Incentives database, developed and managed by the National Renewable Energy Laboratory (NREL), is helping to address the batteries need. The database is intended to help advance the adoption of zero-emission vehicles by providing information and data that inform the production of EV batteries and development of a secure domestic battery supply chain. The database allows users to search for policies and financial incentives by jurisdiction, battery chemistry, federal agency, status, and type, as well as other topics, to customize the information to each specific need.”

Ubergizmo: iOS 15.4 Reportedly Causing Pretty Severe Battery Drain For Some Users

Ubergizmo: iOS 15.4 Reportedly Causing Pretty Severe Battery Drain For Some Users. “According to some users, they are only getting half of the battery life that they got previously prior to the update. Some users are also reporting that they are seeing the battery drain by as much as 5% in less than 10 minutes, while some are also saying that their phones are now lasting them half a day. However, there might be some good news and that is this battery drain might not necessarily be a bug.”

The Graphene Council: Tonnes Of Used Face Masks To Be Turned Into Energy

The Graphene Council: Tonnes Of Used Face Masks To Be Turned Into Energy. “Researchers say that during the coronavirus pandemic people on the planet started using more than 130 billion masks every month, which turn into hundreds of tonnes of polymer waste. When burned it emits toxic gases, so the task of recycling this waste is particularly urgent. Scientists at NUST MISIS, together with their foreign colleagues, have developed a new technology for producing cost-effective batteries from used masks, where waste drug blister packs are also used as a shell. Thus, medical waste forms the basis for creating batteries; all that needs to be procured is graphene.”

Purdue University: Dark mode may not save your phone’s battery life as much as you think, but there are a few silver linings

Purdue University: Dark mode may not save your phone’s battery life as much as you think, but there are a few silver linings. “When Android and Apple operating system updates started giving users the option to put their smartphones in dark mode, the feature showed potential for saving the battery life of newer phones with screens that allow darker-colored pixels to use less power than lighter-colored pixels. But dark mode is unlikely to make a big difference to battery life with the way that most people use their phones on a daily basis, says a new study by Purdue University researchers. That doesn’t mean that dark mode can’t be helpful, though.”

BetaNews: Batterygate: Apple to pay $113 million for throttling iPhone performance. “Starting back in 2016, Apple used updates to iOS to throttle the performance of older iPhones in a bid to improve battery life. While the company’s intensions may have been good, the fact that customers were not warned about the reduction in performance did not work in its favor.”

Solar Power World: UL launches database of thermal runaway-tested battery brands and models
