Increase energy density for longer life

A new class of catholyte

Primary batteries, with energy density three times higher than Lithium ion, are critical for applications where recharging is impractical or impossible such as medical implants, remote monitoring and unmanned vehicles. This team is developing a new class of energy-dense catholyte, based on liquid fluorinated reactants, that can increase the energy of a Lithium primary battery by 20 percent or more
