New battery charging speed increased thousands of times

　　In recent years, the rapid development of electronic technology, computer components have become smaller and smaller, but the battery technology and battery life are relatively backward, restricting the development of smart phones and other mobile devices. Therefore, it is particularly urgent to carry out technological innovation on batteries.

　　According to a paper published in the latest issue of the journal Nature Communications, researchers at the University of Illinois led by Professor William P. King have recently developed a new type of lithium-ion microbattery. The thickness of this new type of super micro battery is only a few millimeters, the volume is 30 times smaller than the previous battery, and the charging speed is 1000 times faster than other technologies.

　　Lithium-ion micro-batteries are made of high-power lithium-ion batteries with fast charging positive and negative electrodes with a 3D microstructure. The power density of this miniature battery is 2000 times higher than that of the current battery, which can reduce the size of the existing battery by 90%, or provide 10 times the power of the existing battery; at the same time, it can help extend the broadcast signal up to 30 times, and It avoids the trade-off between battery life and performance and breaks the limitation of only one trade-off between battery life and power in the past.

　　At present, this new battery technology is still in the experimental stage, and there is still a long way to go before commercial applications. However, the research team hopes to start commercial trials of this technology later this year, planning to integrate the technology into other electronic components, and is also studying low-cost production processes.

　　Industry insiders believe that if the technology is successfully implemented in commercial applications, it will have a revolutionary impact on the current consumer-level mobile digital market, and the biggest beneficiaries are obviously smartphones and tablets, and it will also promote the continuous development of screens and other hardware. Innovation.

　　The development of electric vehicles drives the increase in demand for lithium

　　At present, environmental protection has become a major trend in economic and social development, and the development and application of electric vehicles have also begun to accelerate, which will also drive the demand for lithium batteries.

　　Industry insiders pointed out that lithium batteries are recognized as the most promising power battery. At present, in terms of technology, pure electric vehicles seem to have no other options and must rely on the development of lithium batteries. McKinsey predicts that by 2020, the lithium battery car market will be competitive.
