Pacific Northwest National Laboratory scientists have uncovered a root cause of the growth of needle-like structures – known as dendrites and whiskers – that plague lithium batteries, sometimes causing a short circuit, failure, or even a fire. Such defects are a major factor holding back the batteries from even more widespread use and further improvement. […]

University of Maryland researchers have figured out how to increase a rechargeable battery’s capacity by using aggressive electrodes. They stabilizing these potentially dangerous electrode materials with a highly-fluorinated electrolyte. The success of electric car batteries depends on the miles that can be driven on a single charge, but the current crop of lithium-ion batteries are […]

University of Akron’s Professor Dr. Yu Zhu’s research group is trying to prevent if a powerhouse of energy – a lithium battery – failed. An electric or hybrid car would be rendered useless and a much-needed biomedical device would hamper or endanger a patient’s health. The power source for things like implanted medical devices, electric […]

An Argonne National Laboratory team of researchers has identified one of the major culprits in capacity fade of high-energy lithium-ion batteries. Scientists refer to a battery becoming old is its diminished performance as “capacity fade,” as the amount of charge a battery can supply decreases with repeated use. Capacity fade is the reason why a […]

Oak Ridge National Laboratory (ORNL) scientists have found a way for recycled tires to see new life in lithium-ion batteries. By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team is developing a better anode for lithium-ion batteries. The team led by Parans Paranthaman and Amit Naskar is developing […]
