New Battery Technology

Over at Peter Grant's blog mention was made of a new battery technology. The article that was linked to describes the new technology as the work of a team led by 94-year-old John Goodenough, co-inventor of the lithium-ion battery. The inventors claim the technology is safer (less combustible), faster charging, has greater energy density, and a longer life (number of charge/discharge cycles). If it pans out that'll be quite an improvement. I guess Goodenough decided the lithium-ion battery wasn't good enough.
