While it's always good news that there's research going on in this field, the litmus test is still: do they have a large scale production process developed yet?

While it's always good news that there's research going on in this field, the litmus test is still: do they have a large scale production process developed yet? Currently the real revolution is the increasing density and thus cost-effectiveness of LiFePO4 batteries, which recently reached $100/kWh in certain applications and made the DoE revise its target from $80/kWh to $60/kWh. High energy density and quick charging are nice-to-haves and would enable electric airliners, but what should be the focus for now is cost-effective grid-level energy storage - LiFePO4 are inching closer to that with every passing year.
