Battery reporting is still painful huh? People still not learning how to report? You need a table with at minimum: density, charge time, number of cycles, cost

Battery reporting is still painful huh? People still not learning how to report?
You need a table with at minimum: density, charge time, number of cycles, cost to produce, state of development (lab, factory prototype, production…). Bonus points for losses/efficiency/your special metric that you can win on.
Density matters even for stationary storage. Less, but you can’t just omit it. Like you can’t omit it for gravity batteries which have an energy density comparable to that of raw lemons.
- lostlogin 2y agoI think this holds for reporting on any field where you have expertise or deep knowledge. I read the news and just end up frustrated that something happened, and I don’t have the key details.
- laserbeam 2y agoI don’t actually have that domain knowledge in case of batteries. Yet, without that info, every week for the past one or two decades some company or research team promises a battery breakthrough. None of them manage to mass produce. In this field if you can’t spell the basic stats you are basically hiding that you don’t yet have a product.
- unwind 2y agoI would expect "basic cell voltage" too, I find it super weird that is almost always omitted. I get that heavy-duty (they're shipping container-sized based on the renderings in the annoyingly designed scroll-to-change-everything page) batteries will probably contain multiple cells, but what is the basic bare voltage of the chemistry? Please.
