Lithium-Ion Batteries for Less

—

A new way to make advanced lithium-ion battery materials addresses one of their chief remaining problems: cost. Arumugam Manthiram , a professor of materials engineering at the University of Texas at Austin, has demonstrated that a microwave-based method for making lithium iron phosphate takes less time and uses lower temperatures than conventional methods, which could translate into lower ...

Key to Cheaper Lithium Ion Batteries Could Be Inside the Microwave [Research]
Gizmodo — ... microwaves to cut costs. The new method requires lower temperatures (300° C rather than 700°) and less time to fabricate the phosphate via the nuking process—just like throwing that Tombstone in the m-wave rather than the oven. The tech probably won't trickle down into laptop batteries, which use a lithium cobalt oxide that isn't capable of the quick bursts of current needed to get something like the Chevy Volt rolling. All the better to crash your Tesla with. [Technology Review] ...

Microwave process could cut cost of lithium-ion batteries
Engadget — ... While there's plenty of folks out there focused on making lithium-ion batteries safer and longer-lasting, there's also thankfully some dedicated to making 'em cheaper, which is especially welcome when we're talking about the expensive batteries powering ...

Lithium-ion Phosphate Batteries Baked in a Microwave Could Lead To Cheaper Prices
Wired: Gadget Lab — ... But why are these better than others? Lithium-ion phosphate batteries, once produced, are considered among the most energy efficient types because of their 'energy-to-weight ratios, and their slower charge loss rate.' While companies like A123 Systems have started to develop this type of battery separately, Prof. Manthiram's method is different enough that companies have already contacted him about implementing his process into the new batches of batteries.
