The Verge:

This isn’t an investment column, and I am not an investment adviser. But here’s a free financial tip: if any company actually mass-produces a new, safe, practical, affordable, reliable, proven, much longer-lasting type of battery for digital devices, buy stock. Buy a lot of it. Because batteries are the key to every electronic device we now depend upon — especially smartphones and laptops — and they are the weak link in the system.

He’s right. And it’s not just digital devices. Better batteries are the key to the electric car’s future, too.
