Five cutting-edge battery technologies improve battery life

In the past few years, many smartphones have started to sell excellent battery life as one of their selling points, and the actual performance has indeed improved a lot. In fact, in the past few years, the entire smartphone market has made great progress, but there has been no breakthrough in the development of the battery field alone. Our smartphones are slimmer, faster, and have more powerful processors, but manufacturers seem to be at a loss when it comes to adding battery life. Fortunately, many companies and scientific research institutions have seen the industry's desire for battery technology advancement. It can be said that whoever can launch a new type of battery technology that can be used in the future will be the first to take the initiative in the market. The product area will also continue to advance by leaps and bounds with the advancement of battery technology. Below is a summary of some interesting technologies that may lead to significant advances in battery technology in the future. The first technology does not seem to be directly related to the battery, but it can also extend the battery life from the side. Researchers from Purdue University, Intel Corporation, and MobileEnerlytics analyzed the use of 2,000 Android-based smartphones and found that the apps installed on the phone drained 28.9% of the battery power when the screen was off, because the apps frequently wake up and run in the background. So they developed a system called HUSH, which can extend battery life by 16%, and published the code on GitHub.

Charlie Hu, a professor of computer engineering at Purdue University, said that while the screen is off, computer hardware should go to sleep, and power consumption should be close to zero. Apps periodically wake up the phone to do something useful, but after they're done they're supposed to put the phone back to sleep, but due to a bug, or rather incorrect use of the Android power control API wakelock, the phone can't go back to sleep. The HUSH system dynamically identifies background application activities that are of little use to the user, and suppresses the background activities of these applications when the screen is off to save power.Also read:https://www.aimeno.com/lifepo4-battery-cell/lists_98.html

If you have a smartphone that has been used for many years, you will find that its internal flash memory is not working smoothly. However, researchers at Hanyang University have announced a new technology that could slow the rate at which flash memory cards rot, improve performance and increase smartphone battery life. The technology is named WALDIO, directly abbreviated as IO. The idea is all designed around internal NAND flash for storage. The constant writing eventually leads to corruption and also slows down the read and write process of all applications. Also, reading and writing to flash memory cards is an energy-consuming process, so optimizing these types of tasks could add to smartphone battery life. Simply put, WALDIO wants to increase the lifespan of a flash card by reducing the amount of data it has to record. In a test with a Samsung Galaxy S5, there was a significant reduction in total IO capacity when performing heavy operations. Reduced to about 1/6 of the original. This test also tested the default method for up to 4.6 times faster command performance to free up more time for other storage tasks. This form is beneficial for us users, our smartphones can operate up to 20 times faster in a certain task, so the battery life will increase by 39% or more. That is to reduce the reading time by reducing the storage system log, and increase the response speed, which is the storage speed, to achieve the purpose of reducing power consumption. New lithium battery At present, lithium batteries are the raw materials used in most electronic product batteries, but limited by the lithium element, only part of the ions are used, and part of the electricity is actually wasted. In 2014, a research team at Stanford University developed a new type of lithium battery, which can not only provide longer battery life, but also greatly extend its service life. Through the nano-carbon shielding technology, the battery can shield those unstable chemical elements that shorten the lifespan, allowing more active and denser lithium ions to gather on the anode of the battery, thereby obtaining a longer repeated charging life. In addition to improving life, the safety and stability of lithium batteries are also improving. Former U.S. Secretary of Energy Steven Chu, who led the team at Stanford University, estimates that these new lithium batteries could achieve two to three times the life extension, allowing automakers to build cheap electric cars that also provide a healthy driver. RF-DC conversion In fact, mobile phones emit radio signals all the time, and the energy of radio signals can be used to improve the battery life of mobile phones. Researchers at Ohio State University have developed circuits that convert radio signals emitted by cellphones into electrical energy, which can then be charged to batteries. According to the researchers, this technology can extend the battery life of mobile phones by up to 30%. Ohio State University is working with startup NikolaLabs to commercialize it. They say the technology can be easily deployed inside a phone case. The technology requires an antenna to collect radio signals, and a rectifier to convert the collected signals from alternating current to direct current to charge the battery. According to Ohio State University, this technology can obtain power from radio signals up to a few microwatts, and can obtain power from radio signals to extend battery life without affecting the quality of mobile phone calls or data connection speeds. hydrogen fuel cell Hydrogen fuel power cells have always been regarded as the best form of battery technology, but so far, the stability of hydrogen fuel power cells is still very poor. But it seems that it won't be long before this hydrogen fuel cell can also appear in the smartphones we use.Also read:https://www.aminobattery.com/lithium-battery/ According to British media reports, the technology company IntelligentEnergy has developed a hydrogen fuel cell, which can last up to a week after it is placed in the iPhone 6. IntelligentEnergy put its own battery into an iPhone 6, but without changing the shape or size of the phone at all, it worked perfectly. This technology is actually a reaction between hydrogen and oxygen to produce electricity, and a little water and heat. The only difference in this iPhone 6 is that there are holes on the back so that water vapor can escape. In addition, the hydrogen supply is charged through the adjusted headphone jack. It is reported that IntelligentEnergy is working closely with Apple. Both parties declined to comment.
