Researchers create algorithms that could help lithium-ion batteries charge two times faster
Researchers at the University of California San Diego have devised new algorithms that could cut lithium-ion battery charge times in half, help cells run more efficiently and potentially cut production costs by 25 percent. Rather than tracking battery behavior and health with the traditional technique of monitoring current and voltage, the team's mathematical models estimate where lithium ions are within cells for more precise data. With the added insight, the team can more accurately gauge battery longevity and control charging efficiency. The group was awarded $415,000 from the Department of Energy's ARPA-E research arm to further develop the algorithm and accompanying tech with automotive firm Bosch and battery manufacturer Cobasys, which both received the remainder of a $4 million grant. Wondering if the solution will ever find its way out of the lab? According to co-lead researcher Scott Moura, it'll see practical use: "This technology is going into products that people will actually use." Update: UC San Diego reached out to let us know that they were awarded $415,000 (not $460,000 as previously noted) out of a grant totaling $4 million (not $9.6 million), split between Bosch and Cobasys. We've updated the post and the press release below to reflect the correct figures.
A123Systems crafts long-lasting automotive Li-ion for electric cars
A123Systems most certainly won't go down as the first startup to crank out what could be the batteries that reside in our future electric vehicles, but it seems to be edging ever closer to landing a full-blown contract with General Motors. GM has already selected the Massachusetts-based company to "develop batteries that might be used for the Saturn Vue," and it is pondering the idea of awarding the battery maker a similar deal for the Volt. The firm is garnering a good bit of praise for its "long-lasting, safe rechargeable Li-ions" that could potentially power the all-electric / hybrid vehicles of the future, but rather than relying on "cobalt oxide, it used iron phosphate assembled in a novel, nano-structure." Interestingly, the outfit's current offerings started out with the idea of utilizing self-assembling cells, but after they proved "intractably hard to develop," the idea was scraped in favor of the less pricey Li-ion approach. Still, don't expect these guys to run the table on automotive contracts, as there's already quite a few formidable opponents on the loose.
