DailyDirt: Better Batteries
from the urls-we-dig-up dept
Storing lots of energy conveniently is one of the world's greatest challenges. Batteries have improved a lot over the years, but not quite at the same rate as the electronics they power. There are a number of battery research projects, and here are just a few.
- Batteries that can be recharged from humidity in the air sound awesomely impossible. Still, people are working on them... [url]
- Flow batteries can be quickly recharged by refueling them. New designs promise an almost ten-fold improvement in energy storage density. [url]
- Microbial fuel cells (MFCs) have plenty of room for improvement before they'll be used in commercially-available devices. And now, we know a bit more about the proteins that make MFCs possible. [url]
- Lithium batteries are getting better and better -- gaining over 1,000 recharge cycles and increasing energy densities. If only batteries followed Moore's Law... [url]
