Of course I can't find the links now via Google, but I saw an announcement recently (multiple actually) about batteries in development that are not affected by cold temperatures AND have higher charge capacity AND speed than Li-Ion. I believe (guessing here) it involved aluminum (but not those charge-only-once aluminum-air batteries... something else).

If those batteries were released commercially within the next 5 years, it would be a game-changer

I have just been scheduling a 100% charge overnight when its below freezing to compensate for the loss of battery efficiency. Normally I just charge to 80%. This is mostly just for peace of mind, my trip is about 20 miles each way.
