Compared to the pure polymer, the polymer-graphene nanocomposites possess much higher active material utilization ratios and superior ultrafast-charge and -discharge ability; one of the materials maintained a discharge capacity of 100 mAh/g even at 100 C, when the whole discharge process takes only 16 seconds. graphene nanocomposites.

State-of-charge mapping of lithium iron phosphate electrode powder dispersed by sonication. Using X-ray and electron microscopy, researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate (LiFePO 4 , or LFP).

Rechargeable magnesium batteries are of great interest as potential “beyond Li-ion” systems for extended electric vehicle range. Because magnesium is divalent, it can displace double the charge per ion (i.e., Mg 2+ rather than Li + ). As an element, magnesium is more abundant than lithium, and more stable.

Volkswagen is holding media drive events this week for the sporty new 2013 Jetta Turbo Hybrid ( earlier post ), which features the second version of a Volkswagen gasoline-electric hybrid drive system: a 1.4L kWh Li-ion battery pack. The Jetta is the first Volkswagen hybrid with a Li-ion pack (cells from Sanyo).
