Lithium-ion battery bottlenecks depend

In fact, cell phones and batteries are more like pairs of conjoined babies. The relationship between them is inseparable. Nowadays, when people buy mobile phones, battery life is a necessary consideration for them.

From the past to the present, the battery life has always been a common problem, and it is also a major obstacle to mobile phones. Nowadays, most of the mainstream smartphones are only able to meet their daily use requirements. There are very few mobile phones that can handle more than two days of usage.

In recent years, the major mobile phone manufacturers, device companies, etc. are also racking their brains to invest in research and development, as much as possible to ensure the battery life is normal or even longer. How to charge more electricity in a shorter time, and at the same time, to ensure more long-term battery life on the basis of more electricity, this is what we all want to see.

The development of smart phones is now too fast and the replacement speed is too fast. With smart phones becoming more and more comprehensive, remote control, listening to music, watching movies, GPS navigation, etc., have become an integral part of people. Imagine if you were on the way home on one day, suddenly the phone There was no electricity. At this time, you didn't have a charging treasure, but you needed to open some products in your home. Finally, you couldn't meet the demand because of battery problems.

Now that the culprit of smart phone power consumption thinks about it, it also knows that the screen, processor, and network of a mobile phone are the culprits in the fast power consumption of mobile phones. The current battery technology used in smart phones is still the lithium-ion battery that Sony invented in 1992. After more than ten years of development, although fuel-powered, solar rechargeable batteries and other technologies have emerged, they have high manufacturing costs and low conversion rates. The current technology, lithium-ion batteries can not be replaced. Lithium is present in the electrolyte rather than in the anode, limiting the energy efficiency and lifetime of the battery. The anode of a lithium-ion battery is currently made of graphite, and scientists believe that the ability of this material has now reached its limit. Silicon and lithium metals are potential replacements for graphite, and some R&D teams are observing the possibility of using ** as an anode.

According to recent reports, researchers at the Nanyang Institute of Technology in Singapore used batteries of titanium dioxide gels as anodes. Although the effect of this material change on the battery life is not obvious, it can significantly speed up the charging of batteries. , and increase the number of charge cycles that they can withstand.

Write to the end

For now, vendors are always making big fuss about mobile phone configurations. In fact, the battery reform should also become a major focus of research and development. Since battery life is still a problem, some manufacturers use battery storage methods to increase battery capacity or increase charging speed in order to increase the life of smart phones. In the future, if it can not only solve the battery charging problem of the form, but also solve the problem of life is good, it will become another change in the mobile phone industry.
