Yesterday there was also an article about Li-Air cells, so there is certainly a great deal of interest in battery technology. Both articles mentioned capacity but didn't touch on discharge characteristics. Capacity is certainly an important attribute, especially when you see a tear down for a cell phone or tablet, the battery takes up most of the device. As we look to the feasibility of EVs, though, discharge characteristics become very important.
@tekochip - Interesting to see we are looking at improving the batteries we have in the market, especially the ones on our smartphones, tablets, laptop. There are instances where I really run out of power when I really need my smartphone.
Boosting the capacity of lithium-ion is going to be a challenge. Mature battery technologies typically reach about 40% of their theoretical energy and lithium-ion is already there. The addition of dead weight components -- electrolytes, terminals, housings -- boost the mass and reduce the specific energy. That's why so many battery developers have begun to look at lithium-sulfur, lithium-air and other chemistries that are farther out.
With my first cell phone, years ago, I remember taking short trips without packing my charger. Today, that's not possible. I constantly see people hunting for power outlets in airports or desperately borrowing chargers from co-workers.
A higher capacity on lithium-ion batteries would only mean good things for the future of the mobile industry. Smartphones are getting more feature-rich and resource-hungry with each iteration. This is a necessary evolution to cater to such needs, while ensuring lengthier talk times.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
