The ability to &quo...And it is not just companies. The ability to "hide" (maybe from oneself) the real issues is a pain and slows progress. What we need is a well established certification program (i.e, what NREL did for solar). Has been talked about for a decade, but it is hard to implement. So the games continue. When I first started writing this blog, I wanted to get at the heart of this issue: examine, critically, all the claims and provide context. Realized very soon that it was hard. Lack of info.

This dependence of battery design, cycling conditions, voltage of operation, etc. on performance is the reason battery companies have been getting away with obfuscation. Most (not all) battery chemistries can be made to perform well for a particular metric. The trick is getting all the metrics to work out for the same battery."<br /><br />Definitely one of my biggest gripes and something that certainly cause the somewhat questionable reputation of battery startups (even if it is not truly deliberate and even if it got them a lot of funding along the way).<br /><br />If nothing else, batteries are a complicated optimization problem, where the devil is in the details.Anonomoushttps://www.blogger.com/profile/09864495730853599918noreply@blogger.comtag:blogger.com,1999:blog-6002016549730514348.post-9250848543510309242015-10-20T20:02:11.631-07:002015-10-20T20:02:11.631-07:00I see a LOT of hope for improvements in batteries....I see a LOT of hope for improvements in batteries. I probably should blog about the battery roadmap sometime soon.<br />Solid state, sadly, is still, in my opinion many years away. A decade away in any large application. Will probably hit niche applications in the next few years.

With Dyson purchasing Sakti3 and Bosch acquiring Seeo it seems as though there may be some hope for improved battery capacity through solid state electrolyte batteries.<br />cztreehttps://www.blogger.com/profile/04234930515670145794noreply@blogger.com
