Graphene lithium-ion power lithium-ion battery science

Data related to graphene-based lithium batteries show that this year's new energy passenger vehicles have continued a seven-month upward trend from the previous month. According to industry insiders, the new energy automobile industry has just started and will maintain a compound growth rate of 30% in the next few years, which is the industry with the most certain rise. With the rapid development of new energy vehicles, the power lithium battery industry, which is the heart of new energy vehicles, is also rising rapidly, and the output value of lithium battery manufacturers is also increasing. On July 8, 2016, the world's first graphene-based lithium battery was announced in Beijing. Experts believe that the success of this product has developed the potential of graphene for lithium batteries for consumer electronics, electricity and energy storage. It has good functions and can work in an environment of -30-80. The battery life is as high as 3500 times, and the charging efficiency is 24 times that of ordinary charging products. In fact, the charging and discharging speed of lithium battery electrodes is determined by the transport and speed resolution of intercalated lithium ions. He said that graphene has excellent electronic and ion conduction functions and a special two-dimensional single atomic layer structure, which can be between particles. The data constitutes a three-dimensional electrode and ion transport network structure. If the use of graphene materials is successful in lithium batteries, the charge and discharge rate of lithium batteries can improve with the ups and downs, complete a major breakthrough in battery technology, and will promote the new energy industry and lithium The battery manufacturer has completed a leap-forward development. The development of lithium battery vehicles and the use of electricity to replace oil are one of the strategic ways to ensure my country's energy security. At that time, the functional requirements of fast charging, high energy and long life of power battery electric vehicles, engaged in the development of high-quality graphene-based lithium-ion power lithium-ion batteries for electric vehicles, power generation oil helped to occupy a favorable position in the lithium battery category In our country, the category of new energy vehicles that improve our country’s international competitiveness, in general, the goal of industrialization can make my country’s lithium-ion power lithium-ion battery products for electric vehicles reach the international advanced level, and regional advantages will emerge from this. . Project function 1. Proposed the technology of preparing high-quality graphene powder for lithium battery by using small molecule assisted dissolution method, independently planned and built a 100kg graphene powder trial production processing line, and based on the prepared graphene data, the lithium ion power lithium ion Significant progress has been made in battery function. 2. New selection of dispersant and dispersion process, announcing that petroleum-dispersed graphene conductive adhesive has good stability and good processing function and can be directly used in the processing of lithium batteries, solving difficult problems in dispersion, easy assembly and bad graphene In the handling of lithium batteries.
