Breakthrough point of lithium battery technology -Lithium - Ion Battery Equipment
Laptops, smartphones and tablets, MP3, MP4, PSP, digital cameras, video cameras and other mobile devices are rapidly widespread, and the future trend of electric vehicles, and their own batteries can not live, although the development of mobile power, make up for the shortcomings, so mobile The power source is also rapidly expanding, and the power bank and lithium-ion battery are closely related, so the technology of lithium-ion battery has become the focus of many technologies and operations.(Lithium - Ion Battery Equipment)
A simple lithium-ion battery consists of a positive electrode, a negative electrode, a gap and an electrolyte, so the lithium-ion battery technology can be divided into positive electrode technology, negative electrode technology, gap technology and electrolyte technology. In the absence of major changes in battery structure, the development of data technology has driven the development of lithium-ion battery technology in the past few years.
Thanks to serious discussions of new data and new technologies, the key technology for lithium-ion batteries is now in the hands of Japanese manufacturers first. An important cathode data for lithium ions is lithium cobalt oxide, which has the advantages of stable discharge, high energy density, good cycle performance, and high operating voltage. The cathode data is mainly graphite data, which has high specific capacity, is also cheap and easy to obtain. Most of the positive electrode data currently under development will not replace lithium cobalt oxide in lithium-ion batteries in mobile products in a short period of time, while the negative electrode data is seen as a critical tipping point for practical applications in tin gold and silicon-based alloys widely expected. In 2011, Japan's Sony Corporation began mass production of 18650 batteries, using tin-based alloys, with a capacity density of 723WH/L per unit volume. Panasonic also plans to produce 18650 batteries from silicon-based alloys in 2012. Therefore, there has been a new breakthrough in mobile power technology.
Fast charging technology is also the research direction of many companies. Many had previously believed that fast-charging technology would be important for electric vehicles and that smart mobile devices would not be in great demand. But with the rapid proliferation of smartphones and tablets, short battery life and long charging times have become a headache for many users. The treatment is to be done from two aspects: on the one hand, the development of batteries suitable for fast charging, including the selection of positive and negative poles modified by the macroporous/mesoporous data, the improvement of notch materials and hole programming, and everything from solid electrolytes Choose to get used to high current, and so on.
Another is the use of double-layer capacitor (or supercapacitor) elements in mobile devices, which support fast charging and protect lithium-ion batteries from transient high currents.
Wireless charging is also considered as a promising next-generation charging technology, and is used as a key R&D direction by many companies. The existing standards are not uniform and the conversion power is low. In the future development, this trust will be greatly broken.
