Like I said, you can also make a home version of the Edison cell, with simpler technology than the video in your OP.
I don't know exactly what the cost is, but they are more useful as stationary energy storage, since they are relatively heavy, per kWh. By the way those old Exide glass battery jars are collectible items now. The Chinese version employs plastic jugs -- maybe less environmentally friendly, but cheaper.
The lithium titanate cells are quite rugged and durable, and may find a place as safer replacements for EV batteries (less of a fire hazard)
