LR621 battery.Nokia announces new battery technology that can increase mobile phone battery life by 2.5 times

　　Due to the larger amount of transmitted data brought by high-speed networks, 5G mobile phones have put forward new requirements for chip processing capabilities and batteries, and the contradiction between battery life and performance will become more prominent.

　　Now, an established mobile phone manufacturer is preparing to use new materials to solve this problem.

　　Nokia recently published a research result in the international scientific journal "Nature Energy", saying that its Bell Labs and Trinity University Dublin have jointly developed an innovative battery technology.

　　According to reports, the researchers used a composite material based on carbon nanotubes, which can store more energy inside the battery, effectively increase the density, and transmit it at a speed close to the highest theoretical value.

　　Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charging, -40℃ 3C discharge capacity ≥70%

　　Compared with the currently common ultra-thin lithium batteries on the market, the new battery can significantly increase battery life by about 2.5 times in the same volume, and also supports fast charging technology.

　　The announcement also stated that this technology will not only be used in the field of smartphones, but will also be used in various Internet-connected devices in the 5G era, including drones, smart homes, electric vehicles, etc. Improvements in battery life mean that some micro-networked devices can be used without power for up to several years, and the devices themselves can also develop in a smaller and lighter direction.

　　At the same time, Nokia researchers also hope that the new technology can improve existing renewable energy power generation systems. Although the current supply from solar and wind energy is not stable, as long as the system itself has excellent energy storage batteries, its reliability and energy efficiency can be improved.

　　At present, Nokia said it has applied for a patent for the technology, but has not yet specified a timetable for its introduction to the market.

　　This is not the first time that a manufacturer has tried to use new battery technology to change the entire industry. As early as 2015, ETH Zurich stated that a new material composed of vanadate and borate, when combined with graphene to form a new battery, can achieve a longer battery life than existing lithium batteries. The improvement is about 1.5-2 times.

　　Graphene must be mentioned here again. Although manufacturers such as Samsung and Huawei have applied for relevant patents for graphene batteries, we still have not seen any technology implemented. Some experts in the battery industry believe that considering the production cost of graphene, it is not suitable for batteries. The application prospects are slim.

　　Therefore, technological achievements are only the first step in innovation. If you want to drive change, you often need to go out of the laboratory and consider many factors such as mass production and commercial use.

　　Rather than seeking alternative materials, most mobile phone manufacturers are now more inclined to improve charging methods, using "shorter charging time" and "more convenient charging methods" in exchange for users' desire for long battery life. The popular wireless charging technology in the camp is the best proof.

　　Just this year, Xiaomi and Vivo have successively announced their own new fast charging technology, and the power has exceeded the level of 100W or even 120W. The latter even claims that it can fully charge a 4000 mAh battery in 13 minutes. I believe it It is also making technical reserves for 5G mobile phones.

　　Returning to the material issue of the battery itself, in the short term, the demand for lithium batteries in the mobile phone industry will not decrease. Coupled with the development growth rate of electric vehicles and other fields, and the promotion of large-scale factory construction, several lithium batteries The supply of core raw materials is also becoming increasingly tight. As for when new materials will bring changes to the entire industry, it is still unknown.
