    Basically all the battery technology research of the last two decades or more has been trying to make them more energy dense and lighter for mobile devices and vehicles. However this doesn’t matter very much for stationary backup storage, so there are still a lot of low-hanging fruits for people to develop cheaper and more durable battery storage. In fact most of these systems still use lead-acid batteries, which are quite ineffecient.

      Thing is that even though this is indeed the main focus, as a byproduct of that research we literally have dozens of alternative battery chemistries available with different features.

        Indeed, but they need to be also be made available for people to buy and that usually still involves a lot of further product development. Right now it seems more common to just re-purpose automotive lithium-ion batteries for stationary storage, which might be better than lead-acid batteries, but really isn’t ideal either.

          That’s what hackerspaces and fablabs are for!

          Disclaimer: I am a member of a fablab that explores open hardware automation and solar techs :-) We have talked about producing batteries but have too many items on the todo list for now
