Researchers Create Sodium Battery In Industry Standard "18650" Format (gizmag.com)

Zothecula sends word that a French team has developed a battery using sodium ions in the usual "18650" format. Gizmag reports: "A team of researchers in France has taken a major step towards powering our devices with rechargeable batteries based on an element that is far more abundant and cheaper than lithium. For the first time ever, a battery has been developed using sodium ions in the industry standard "18650" format used in laptop batteries, LED flashlights and the Tesla Model S, among other products."

It seems like we're getting announcements about revolutionary world changing never seen before astounding new battery designs every day, but nothing ever comes to market.

Maybe it's time to question what the fuck is wrong with the shitty "journalism" that tries and make huge stories out of nothing.

Assuming a linear-ish discharge curve over a 70% discharge, 1.44Wh D cell to 18.5Wh (equivalent) C cell is not a 2x capacity increase.

I want battery technology to increase an order of magnitude every year too, ... but come on. We've made enormous strides.

You, yourself, can buy low-resistance, low-self-discharge lithium ion batteries at 250Wh/kg. And they're cheap. Compare that to 30Wh/kg NiCD batteries of 30 years ago.
