OSAKA -- A team of researchers from Kyoto University and Toyota Motor is making solid progress developing next-generation battery technology that has the potential to cram far more energy into a small, lightweight package than today's standard lithium-ion, or li-ion, batteries.

The new fluoride-ion battery the researchers are working on, which would hold about seven times as much energy per unit of weight as conventional li-ion batteries, could allow electric vehicles to run 1,000 km on a single charge.
