Power/Performance Bits: Apr. 10


Lithium-air battery Researchers at the University of Illinois at Chicago and Argonne National Laboratory designed a new lithium-air battery that works in a natural air environment and still functioned after 750 charge/discharge cycles, a record for this battery type. In theory, lithium-air batteries work by combining lithium present in the anode with oxygen from the air to produce lithium p... » read more

Power/Performance Bits: Nov. 3


Lithium-air batteries gain ground Scientists at the University of Cambridge have developed a working laboratory demonstration of a lithium-oxygen battery which has very high energy density, is more than 90% efficient, and can be recharged more than 2000 times. Their demonstrator relies on a highly porous, 'fluffy' carbon electrode made from graphene (comprising one-atom-thick sheets of ca... » read more
