New Argonne Patent For Safer Li-ion Batteries

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have patented a new molecule that provides overcharge protection for lithium-iron-phosphate batteries.”The new redox shuttle, known as 2,5-di-tert-butyl-1,4-bis(2-methoxyethoxy)benzene or DBBB, works by halting the charging process of individual cells as they come to a full state of charge,” Argonne materials scientist Khalil Amine said. “Being able to discontinue the charging process on a cell-by-cell basis protects the entire battery pack by preventing individual cells from overcharging.” Currently overcharge is being addressed by expensive and complicated battery management system that use external cell monitoring and control devices. Overcharge can cause damage to the battery, reduce cell life and in extreme case result in thermal runaway. Thermal runaway is a…

EV Drivers Demand Charging At Home

 

Utilities will need to ensure their distribution systems are ready for electric vehicles (EVs) because an overwhelming number of drivers envision they will charge their EVs at home, new Chartwell research shows.

Coinciding with the launch of its EV Customer Strategy Research Council and forthcoming EV conference, Chartwell has conducted a study that reveals 89% of consumers would be “likely” or “extremely likely” to charge their plug-in EVs at home. In fact, the recent survey of 1,500 North American consumers shows that 81% of that group would fall into the extremely-likely category. This was a far greater percentage than consumers who foresee external charging stations as the primary means for fuel.

“We’ve uncovered some interesting findings,” said Stacey Bailey, a Sr….
