It’s good to know that it does at least perform about as well as current conventional batteries. The energy density and cycle life were the really off-the-wall claims. It’s exciting to hear that they’re continuing to test, can’t wait for more third party results!

Edit: Reading the report, they talk about “charge capacity” (Amp hours in/out) efficiency of 98.4% to 99.6%, but this seems potentially misleading. The actual charge energy efficiency is more like 90%.

> Successfully delivered 98.4-99.6% of charged capacity even after extreme 11C charging

Note the Wh numbers for discharge vs. charge energy.

Yup, those 2 are the ones I really want to see.

The energy density isn't out of line if this is a true solid state battery. The cycle life, though, is AFAIK. I don't believe solid states have that sort of cycle life.
