Power/Performance Bits: Feb. 10


Balancing battery capacity and stability Researchers at Rice University are working to develop batteries that are better geared toward electric cars and more robust off-grid energy storage by digging into why lithium gets trapped in batteries, thus limiting the number of times it can be charged and discharged at full power. The team found that by not maxing out a battery's storage capacity,... » read more
