The curse of external battery packs isn’t going away anytime

Why are phones so good but batteries are still so terrible?

Curated via Twitter from The Verge’s twitter account….

According to Venkat Srinivasan, director of the Argonne Collaborative Center for Energy Storage Science and an expert in battery technology, the core of the issue is simple: Moore’s Law has simply outpaced battery technology, meaning that our phones have gotten better — and demanded more power — at a much faster rate than advancements in batteries have.

That’s because today’s rechargeable batteries in phones are based on lithium cobalt, a battery technology we’ve been using since the early ‘90s, and we’ve largely reached the limit of how much power we can squeeze out of it.

There is a catch, though: by the time those new batteries roll around, our phones may be even more advanced and need even more power, which could leave us right back with the same, one-day battery life that we started with.

Researchers are already investigating new battery technology, like solid-state batteries, that could open the door to more energy-dense materials that could offer more power for future devices.
