I can only hope these can actually hit commercialization, unlike most new battery technologies that never leave the lab.
Yes, because battery technology stagnated years ago...
Oh wait
All that data says is batteries got cheaper so they are putting more of them into cars. Also 100 to 300 wh/kg is in labs. No explanation why it went from 175 to 100 Wh/kg 08-10.
We've had 3 major changes in battery chemistry in the last 45 years. Energy density, lifespan, cost, and dangerous materials have all generally improved. We also have 2 new battery technologies in the process of becoming generally commercially available. Also, batteries went from 500 mAh batteries about the size of your smartphone to 3000 mAh as a minor component of that same smartphone, about an order of magnitude in energy density.
