This week in batteries (TWIB): Pull the plug. Your battery will thank you.

This week in batteries (TWIB): Pull the plug. Your battery will thank you.: "By 2 AM you have a fully charged battery. If you leave your house at 8:00 AM, your battery is going to be sitting at 4.2V for 6 hours in any 24 hour period. This is not going to be good for the battery. It gets worse if you decide to bump the amp/volts on your house to charge it faster. So we need to get these batteries charged faster, but we also want to make sure to have smart chargers that don’t do what I’ve described above. Something to think about.

What does this mean for researchers? If someone can find an electrolyte that has a wide voltage window of stability, then this problem goes away. Or you can try to use materials that work within this window (For example A123 Systems battery does this on the positive side)."
