Another story about an aluminum battery. This time from Stanford. The article is a bit light on details, but sounds promising.
Aluminum, graphite and salt:
For the experimental battery, the Stanford team placed the aluminum anode and graphite cathode, along with an ionic liquid electrolyte, inside a flexible polymer- coated pouch.
"The electrolyte is basically a salt that's liquid at room temperature, so it's very safe," said Stanford graduate student Ming Gong, co-lead author of the Nature study.
Safety:
Charging:

Safety:
"In our study, we have videos showing that you can drill through the aluminum battery pouch, and it will continue working for a while longer without catching fire," Dai said. "But lithium batteries can go off in an unpredictable manner - in the air, the car or in your pocket. Besides safety, we have achieved major breakthroughs in aluminum battery performance."
Charging:
the Stanford team reported "unprecedented charging times" of down to one minute with the aluminum prototype
