	Toshiba launches fast-charging lithium ion battery: Digital Photography Review
		Toshiba has today announced a new lithium ion battery, which, it claims, can recharge 80% of the battery's energy capacity in just one minute, 60 times faster than the other lithium ion cells.
		The company's new battery can recharge 80% of a battery's energy capacity in only one minute, approximately 60 times faster than the typical lithium-ion batteries in wide use today, and combines this fast recharge time with performance-boosting improvements in energy density.
		A prototype of new battery (a laminated lithium ion battery with 600mAh capacity) was discharged and fully recharged 1,000 times at a temperature of 25 degrees centigrade and lost only 1% of capacity during the test.
