Adding batteries to a device has one advantage: portability. It also has mutiple disadvantages: batteries add weight, add design complexity, and make it more difficult to fully shut off power in an emergency.

Major household appliances aren’t portable, and are subject to failure modes where you really do want to cut all the power right now and make sure it stays that way. Thus, the disadvantages of adding batteries directly to an appliance outweigh the advantages.

A power wall using this new battery tech would be great, though.
