Why is the battery life problem hard to break?

Why is battery life difficult to break? In addition to batteries, smartphones are good for everything. Why can’t the battery life of the phone be interrupted after so many years of opening? Should we charge it once or twice a day? In fact, after turning on the smartphone for many years, battery life has become a professional vice. Industry insiders pointed out that the key to ending the breakthrough of the battery life bottleneck lies in the conversion of battery materials. In the era of feature phones, it is normal for smartphones to stand by for more than 10 days, and users cannot charge even after using them for a week. Today, the battery capacity of most smartphones is several times that of feature phones, and users have to charge them once or twice a day. The reason is that smart phones have more and more functions, more powerful functions, and larger screens, leading to a significant increase in the energy consumption of mobile phones. According to a survey of iPhone defects by FixYa, a Japanese smartphone user service provider, the battery life is the shortest at 35%. It can be seen that the short battery life of smartphones has become the biggest pain point for users. The reason why the battery life of lithium batteries is close to zero and mobile phones has not improved is because they can only rely on the opening of lithium batteries, and the development speed of lithium batteries cannot keep up with the rising demand for batteries in smartphones. At present, the transformation of lithium battery materials is very slow, and most of them are ahead of the manufacturing process, resulting in only about 10% of the output of lithium batteries per year. Even Elon Musk and Tesla, which are famous for their innovations, have only made breakthroughs in battery management, not the materials and technology of the battery itself, but in the traditional panasonic. Lithium batteries. Especially in the field of mobile phones, the trend is frivolous planning, which is compared with the increase in battery capacity. At present, the ratio of weight to capacity of lithium battery materials is about 150mA/g. Assuming that there is no good industrial plan, simply adding battery capacity will make the phone look terrible. Therefore, many smart phone manufacturers have to throw away bulky batteries to meet their needs. Take the iPhone 5 announced last year as an example. Its built-in battery capacity is only 10 mA more than the previous generation to maintain its ultra-light body. This obviously has nothing to do with its progress. The most important solution for the Eight Immortals Crossing the Sea is to bring a mobile power supply: Although the standby time of the mobile phone is not long, the 10000mAh mobile power supply can basically meet the needs of charging during the journey. The second method is to reform the charging method, such as wireless charging technology, wi-fi signal charging technology, etc., which can alleviate the problem of excessive user data lines to a certain extent. The third method is to rely on mobile phone manufacturers and chip manufacturers Qualcomm and other core components to reduce power consumption, such as processors and screens, as much as possible to optimize the system and interface settings together, to extend the battery life of the mobile phone. Of course, the talents to solve the battery life problem of mobile phones are short-lived, and the terminals of mobile phones can also be built-in with small-capacity batteries together. It can only hope to break the battery material. However, considering the high cost, unproven technology, and problematic safety of new types of batteries such as fuel power cells and nuclear energy batteries, it will take some time before they are truly commercialized. Challenges in the future Although the development speed of battery technology is limited, the smartphone industry is still rising at an alarming rate. The first is the launch and popularization of 4G. Compared with 2G and 3G, 4G mobile phones will consume more energy, and many users choose not to continue using 4G because the battery cannot afford it. 2014 will be a new period of rapid opening of my country's 4G industry. If the battery life cannot be improved as soon as possible, the general speed of 4G will face severe challenges. The second is the emergence of new smart hardware. In particular, most of the wearable smart devices that are small enough to make people comfortable are still lithium batteries. On the one hand, without damaging the lithium battery technology, the extension of battery life means the increase of battery capacity; on the other hand, the battery size of these devices should not be too large, because they are easy to wear.
