li ion 18650 battery pack

　　Without innovation in li ion 18650 battery pack materials, it is difficult to break through the bottleneck of smartphone batteries

　　The arrival of the iPhone 5 has brought with it a lot of topics. One of the hot topics is why the li ion 18650 battery pack capacity of Apple’s iPhone cannot be larger.

　　According to the latest anatomy pictures from the famous teardown website iFixit, the li ion 18650 battery pack capacity of the iPhone 5 is slightly smaller than that of the iPhone 4S. In fact, not only the iPhone, but almost all smartphones on the market have li ion 18650 battery pack capacity bottlenecks. Smartphones in the Android camp are ridiculed on the Internet as a must-have phone for good men because they need to be charged at home every day. This is What kind of mystery is there?

　　li ion 18650 battery pack technology development lags behind

　　The emergence of large-screen touch-sensitive smartphones represented by iPhone has raised the power demand of mobile phones to an unprecedented level.

　　Our existing lithium-ion mobile phone li ion 18650 battery pack technology has been invented for more than 16 years, and there has been no major technological breakthrough, which is why we have such an embarrassing situation now. Zhu Zhiguo, who has worked at BYD for many years and recently opened his own mobile phone accessories store, said that unlike other branches of the electronics industry, the basic principle of batteries relies more on chemical reactions. Breakthroughs in materials are the key to innovation. But so Although li ion 18650 battery pack production processes have improved a lot over the years, there are still no mature alternatives for new li ion 18650 battery pack materials.

　　In fact, compared with the lithium-ion batteries that just appeared more than ten years ago, current mobile phone batteries have improved a lot. However, the problem is that mobile phone functions and energy consumption requirements are developing faster, and the development of li ion 18650 battery pack technology cannot keep up. Zhu Zhiguo gave an example: Nokia's mobile phone worth several hundred yuan has a small screen and few functions, so it consumes less power. The 850 mAh li ion 18650 battery pack can last for two weeks and can last 4-5 days without charging under normal use. But smartphones are different. High-definition LCD screens, 3G Internet access, etc. are all large consumers of power. How can the li ion 18650 battery pack industry keep up?

　　Product thinning is an accomplice

　　Not all batteries for electronic products are devoid of development. On the New iPad, Apple uses a 20481536 ultra-high-definition LCD screen, but the li ion 18650 battery pack life is maintained at the same 10 hours as the iPad. How is this achieved? Apple’s approach is to double the li ion 18650 battery pack capacity and improve the production process. Minimize the space occupied by the circuit board in the NewiPad, leaving more space for a larger li ion 18650 battery pack.
