ADO has had trouble commercialising their products, batteries will probably be no different as there is a lot of competition:

Amprius's silicon anode technology was originally developed at Stanford University and enables dramatic improvements in the energy density and specific energy of lithium-ion batteries.

Nexeon’s silicon anode Li-ion battery technology has numerous applications, and the ‘drop-in’ approach offers significant benefits to battery manufacturers and end users:

3 New Kinds of Battery That Just Might Change the World
The market for a better battery is potentially enormous. Yet as our gadgets and cars have evolved, the batteries powering them have remained pretty much unchanged. And while the press is full of reports of eureka-moment “breakthroughs,” it’s turned out to be remarkably difficult to commercialize any of this new technology on a broader scale, as journalists like Kevin Bullis and Steve LeVine have chronicled (more on that later). Making battery magic in a lab is one thing. Figuring out how to reproduce that magic safely, in a factory, millions of times over, at a price that’s competitive? That’s another.

Solid state technology:
Because there’s no liquid component in these cells—and because they require fewer extra layers of insulation and other safeguards—they tend to be smaller, lighter, and more adaptable than their fire-happy predecessors.

Aluminum air batteries:
In theory, these batteries could have 40 times the capacity of lithium ion batteries,

Aluminum-ion battery:
Stanford University scientists have invented the first high-performance aluminum battery that's fast-charging, long-lasting and inexpensive. Researchers say the new technology offers a safe alternative to many commercial batteries in wide use today.
