Exactly, Rob, it seems like even as researchers are working on new battery chemistries, the industries those new batteries would benefit also are working on the technologies around the battery that would also help solve the power efficiency problem. Perhaps one hand is helping the other here.
I am with you, naperlou, and don't understand a.saji's question. If you're talking about the technology in the story, a.saji, it's not a battery per se. It's technology that can be built into devices to extend the life of lithium-ion batteries--a complementary technology to batteries themselves. That said, I am not sure how long it would extend the battery life. It would probably depend on the battery as well.
I agree, far911, fast-charging is probably more important. But for devices that have hard-to-find batteries, I think lasting long also is a pretty important. Researchers fortunately are working on both aspects.
It's good to see more technology being developed around lithium-ion batteries. Fast-charging is important, but it's also important to be able to do the last 20% of the charge in an intelligent and safe manner. Charging of a lithium-ion battery is often compared to filling a water glass -- the last 10% needs to be done very carefully to prevent "overfilling."
It makes sense to maximize the potential of Li-Ion before moving on to a new battery source. For me personally, faster charging is more important than longer lasting battery. You can't always spare 4-5 hours for your device to charge before you can use it.
With tiny improvements on battery technology coming from a number of directions, it could be the big problems with batteries will be solved one cut at a time. In the meantime, auto makers are improving their internal combustion engines. Good news all around.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
