Rapid improvement of lithium battery performance-Lithium - Ion Battery Equipment

Lithium battery performance is expected to improve rapidly -Lithium - Ion Battery Equipment

The cruising range has become one of the bottlenecks in the development and promotion of electric vehicles. All car manufacturers and related suppliers have spared no effort in investing in this field. In addition to the attempts of different types of batteries, the improvement of the control system has also become a breakthrough point. A few days ago, Nissan Motor Company and its wholly-owned subsidiary, Nissan Analysis and Research Center, announced that they have made further research on battery performance by observing the electronic activity of lithium battery cathode materials during charging and discharging. As a result, new battery technology will enable qualitative improvements in capacity and lifespan.(Lithium - Ion Battery Equipment)

In the existing battery technology concept, as much lithium as possible is stored in the reaction material of the battery, so that more electrons can appear in the reaction material, so that the capacity of the battery is higher, and at the same time, the battery life will be longer. long. However, in order to maximize the performance of this material, it is necessary to accurately monitor the electronic activity inside the battery during the research and development stage. During the charging and discharging process, by observing the electrons are released from specific elements in the lithium battery cathode material. The process helps scientists understand the source of electrons during charging and discharging, and this research opens up room for future battery technology development.

The new method of observation and analysis is the result of research carried out by the Nissan Analysis and Research Center, the University of Tokyo, Osaka Prefectural University, and Kyoto University. When it comes to X-ray absorption spectroscopy (a method for analyzing the internal structure and electronic state of atoms), since the traditional technology cannot observe the electrons actually participating in the electrolysis reaction, a technical fusion is made in this link, by using L absorption The limited X-ray absorption spectrum can observe the electrons directly involved in the electrolysis reaction, combined with the earth simulator (a supercomputer jointly developed by the Japan Space Development Corporation, the Japan Institute of Atomic Energy, and the Ocean Science and Technology Center, this computer is for Calculation processing developed for the purpose of predicting and analyzing the atmospheric circulation and crustal changes of the entire earth) can accurately analyze the number of electron movements.

The battery developed by the new analysis technology has a 150% improvement in energy density compared with the traditional battery, which means that Nissan has taken a big step forward in the field of lithium battery technology, and the battery life of electric vehicles The mileage will also be greatly improved.

Edit summary:

Battery technology is the key to the development of electric vehicles. Nissan conducts monitoring and research on the electronic activity inside the lithium battery through cooperation with colleges and universities, so as to better understand the internal activity characteristics of the battery. Compared with the lithium battery researched by this analysis technology Existing products can have a 150% increase in battery capacity. Taking Nissan Leaf as an example, if the new battery technology is put into use in the future, the cruising range of the Leaf is likely to be close to 300 kilometers (the cruising range of the 2014 Leaf is about 200 kilometers). The new battery analysis technology will not only further promote Nissan The development in the field of electric vehicles will also be a stimulus for the entire electric vehicle industry.
