MIT develops 'hybrid' cathode for smaller, lighter batteries

Scientists at MIT have developed a new type of "hybrid" cathode for lithium batteries, which they say could increase their energy density beyond that of current commercial lithium-ion battery designs.A team of researchers at the Massachusetts Institute of Technology (MIT) has created a new cathode for lithium battery cells, which could allow for smaller and lighter lithium batteries for electric vehicles and consumer electronics. Lithium-sulfur batteries are widely seen as a promising alternative to current lithium-ion batteries relying on transition metals such as cobalt, since sulfur is both ...
