Mobile electronic devices have become an irreplaceable necessity for modern people. You carry your smartphone and tablet everywhere every day, use them to access the Internet, use the App to communicate, or take photos, listen to music, and navigate; unfortunately, almost No device can keep you at full load throughout the day. At present, the development of battery technology seems to have stalled and cannot keep up with the increasing mobile processors or new features. We cannot help asking why the battery on mobile devices such as mobile phones is still so crap? Will there be a solution in the future?
Main reasons for insufficient battery of mobile phones: stagnant technology and overloaded functions
First of all, the battery technology has not made breakthrough progress in recent years, but the mobile phone screen has become larger and larger, the resolution is higher and higher, the processor has also been upgraded to quad-core high frequency, and the performance can even support shooting 4K ultra-clear Video, running large 3D games at the host level, these high power consumption operations put higher requirements on the battery. But as mentioned earlier, when battery technology has not progressed, manufacturers can only extend battery life by increasing capacity or software, which is a temporary solution to the problem. Only by radically changing battery technology can we meet the demand for higher intensity operation. Here's a look at several promising new battery technologies.
Extends lithium ion activity
In the short term, lithium battery technology will still be mainstream due to its simple and safe characteristics, but it can be made more efficient through some improvements. For example, the use of silicon anodes instead of traditional graphite anodes can increase lithium ion activity by at least 10 times, thereby Extended use time. In addition, some scientists are trying to use sulfur, seawater and even air to increase the activity of lithium batteries. Each technology has its own advantages. It can be said that improving the activity of lithium batteries is relatively easiest to achieve.
3D printing and graphene
If you look to the future, better conductive materials may be a revolution in battery technology. At present, the most promising research direction is graphene, which is more compact and has a faster charging speed, which is very suitable for use on ultra-thin smartphones or wearable devices. In addition, 3D printing technology is also an indispensable part. Currently, a professor at Harvard University in the United States has demonstrated the use of 3D printing technology to create an integrated stack electrode, which is only the size of rice grains, which will help manufacturers produce thinner and thinner electronic devices .
Ultra-thin solar charging panel may become the next mainstream technology
No matter what kind of material, any battery is a carrier and has a capacity limit, so how can we get a continuous supply of electricity for electronic equipment? Solar energy may eventually be the best solution. Through a patent filed by Apple, we can see that in the future, the iPhone may integrate an ultra-thin transparent crystal panel on the top and bottom of the screen to absorb light and convert it into electricity. By then, it will be possible to continue to power, and smart phones will also gain new vitality.
All in all, the development of battery technology may be very slow, but it will always change. Maybe next year we will see some substantial breakthroughs in new-generation battery technology.
