Why is battery technology a shortcoming for smartphones?

Smartphone users have already accustomed to charge the battery every night before going to bed, otherwise, the usage of the next day will surely be affected. Because the lithium-ion batteries are unable to keep up with the growth of the smart phone on the screen size and performance, there are few flagship mobile phones that can stick to the frequent usage of more than one day. Why battery technology becomes a smartphone shortcoming?

In the intelligent mobile phone rechargeable batteries, lithium is rather than of anode, electrolyte which limits the efficiency and service life of the battery. If can the development of lithium anode, that our battery can become lighter, smaller, more durable, charging speed will be faster.

Lithium-ion battery anode current is made of graphite, the scientists believe that the ability of the material now has reached the limit. Of silicon and lithium are graphite potential substitutes, and some research and development team in the observation of the possibility of using sulfur as the anode.

Anode material, however, change is not as simple as it seems that some potentially dangerous material, while others can only insist on hundreds of charging cycle. The fact is that we used in lithium-ion battery actual today is currently the highest level of modern science.

In addition to mobile phones, the problem is also in drag on the development of electric ships, cars, and aircraft. Even if the volume increase, the lithium-ion battery is not very efficient.

As for battery technology, how to further development is still difficult to answer this question. Frontier of the scientists is trying to keep on learning, which is why every year there are many super battery technologies came and went.

Battery technology, in short, is a very complicated subject, even collected the brightest minds in the world, but its development is still very slow, we won't see pioneering battery project appear out of thin air.

We see many reports of battery technology breakthrough and literature, all contain a chemical adjustment, aims at a longer period of time from the same battery for more power. Such small innovation how big does not attract attention, but their importance is much taller than any flexible mobile phone or smart watches.

Amprius is a company that is studying the issue. Since joined the silicon in the anode, their research and development of battery can store electrical energy in the current cell increased by 50%.

At the same time, the University of California, Riverside (UCR) researchers are using innovation of the nanoscale materials to enhance the service life of battery and volume, and shorten the charging time. UCR in last year was introduced: a very interesting project uses sand to extend battery life 2-3 times. But the technology is still in its early stages, there are a lot of research needs to be.

Sakti3 is a well-known technology company in the field of cell research. They got from the James Dyson in recently due to investment and reputation, but also do not know their technical details. The news that Sakti3 technology inside the battery will be some substitute solid-liquid chemicals, so as to achieve energy efficiency boost.

Looking for balance

Even if scientists in the field of battery design progress, but it may be limited by other aspects of the technology or denial, which is why the battery technology development will be so slow. Before any substantial development in battery technology itself, we can only by raising the software and hardware of energy saving way to prolong life.

But Microsoft has another idea. Their team will smartphone batteries in two, and one to be responsible for a spate of electricity consumption, another piece is responsible for the use of at ordinary times. According to the early testing, this way can a range 20-50%.

Singapore Nanyang Institute of technology researchers has not been idle. Their latest research and development of the battery using the titanium dioxide gel as an anode, although this kind of material changes in ascension life aspects of the effect is not obvious, but can significantly speed up the battery charging, and increase their affordable charging cycles.

At least 2 years in the future, we still need to charge the mobile phone every night, but there are a large number of researchers are trying to improve the performance of the battery, and they have made progress.
