Batteries are boring. Banal even. A breakthrough is always around the block but no real upgrades in hand. Being application specific, different for the phone, laptop, car, home, grid and so on; each gets used for only a certain period in the day. So, redundant even.
Now, think of a battery you can use in your two-wheeler, car, carry home as a Powerwall, take to work or pack as a compact box for when you go camping. A universal battery pack so to say. Like today, we use power banks for electronic devices.
