Research shows: energy storage lithium battery will lead the electrochemical energy storage technology

A new study by the Technical University of Munich (TUM) shows that the number of patent applications for electrochemical energy storage technology has risen sharply in recent years, most of which are based on lithium. The report 'Monitoring the Innovation of Electrochemical Energy Storage Technology: A Patent-Based Approach' provides a differentiated analysis that analyzes what energy storage technologies are feasible in the export of fossil fuel energy. It also made a sober assessment of the development of battery energy storage in the United States and Europe, pointing out that Western companies 'are economically lagging behind because the number of patents filed by Asian companies has increased significantly. The report pointed out that because wind and solar energy are themselves intermittent energy sources,' If you use renewable energy to process a large amount of electricity in the future, you must store the excess energy during the processing period to compensate for fluctuations. Now, a number of different electrochemical technologies are competing to meet these rising demands. The report says it knows what technology is more intensive The theme of the development activities of the company, and will enter the market in the near future, has important strategic significance for all stakeholders in the energy field, whether it is from the industrial, political or scientific fields. Because the company does not easily disclose its Ru0026D In the event, TUM researchers analyzed worldwide patent applications related to electrochemical energy storage from 1991 to 2011 as part of a large-scale interdisciplinary project on battery energy storage. The study showed that from 2006 to 2011, there were new Patent family, that is, patent applications and patent clusters of similar or equivalent inventions, including applications from different countries, has increased by 110%. In 2006, there were approximately 2,800 developments in intellectual property applications filed. In 2011, this number has been increased to 5,900 Application. Simon C. Müller, a physicist and economist, chairman of the strategy and organization of the TUM School of Management, said: “Given these investments, we can think that new electrochemical energy storage technologies will be ready to enter the market in the near future and will More cost-effective than existing products. 'Researchers have found that so far, most of the patent applications have been filed by lithium battery developers: in 2011, there were 4,900 new patent families. In fact, the number of applications in this field has gone through the curve in 2007. After a single decline, it has been showing a steep upward trend since 2008. Prior to this, many suppliers had to withdraw their products due to safety issues. Müller said: “Obviously, there is a concern that lithium batteries cannot be sufficiently safe. Has disappeared. In addition, new patent applications are cited more times by new patent families than other technologies-this is a quality mark, indicating that they have played a certain role in the continued development of technology. 'In terms of the number of patent applications, the battery ranked second, with only about 580 new patent families in 2011. The researchers also noticed that the number of patents for redox flow batteries has recently increased significantly, although the level is not high, but The energy storage chemical compounds are used in liquid form. From 2009 to 2011, the number of applications more than doubled, from 90 to 200. The number of new patent families for alkaline batteries dropped slightly to 240 However, sodium-sulfur technology has always played a marginal role, with only 20 applications. Müller added: “The field of lithium batteries is very dynamic, and we will soon reach a point where we can see the self-multiplier effect. As long as the technical and economic data are good enough, Ru0026D activities will attract more investment and thus a stronger lead. 'The fact that lithium batteries are also used in electric vehicles will only promote this development, because batteries will be in demand in the energy sector and in the automotive industry.
