Discharge Characteristics

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.

Improving capacity

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.

@Shehan: A common problem we all have. Anyway do you think the improvements of the batteries will not affect the devices ?

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.

Better batteries are needed.

A necessary evolution

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.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
