Innovation in lithium battery monitoring electrochemical energy storage technology -Lithium - Ion Battery Equipment

Introduction: A new study from the Technical University of Munich shows that Asian developers are leading the way in energy storage systems and far outpacing their U.S. and European competitors.

A new study from the Technical University of Munich (TUM) shows that the number of patent applications for electrochemical energy storage technologies has risen sharply in recent years, with the majority being for lithium-based technologies.

The report, Monitoring Innovation in Electrochemical Energy Storage Technologies: A Patent-Based Approach, provides a differentiated analysis of what energy storage technologies are feasible as we exit fossil fuel energy. The report also provides a sobering assessment of battery storage development in the United States and Europe, noting that Western companies have fallen behind economically as Asian companies file significantly more patents.(Lithium - Ion Battery Equipment)

The report points out that since wind and solar energy are inherently intermittent energy sources, if renewable energy is used to produce large amounts of electricity in the future, excess energy must be stored during the production period to compensate for fluctuations. A number of different electrochemical technologies are now competing to meet these rising demands.

The report states that understanding what technologies are the subject of more intensive development activities and will enter the market in the near future is of strategic importance for all stakeholders in the energy sector, whether from the industrial, political or scientific spheres. .

It is understood that Asian developers have filed almost four times as many patent applications as their European counterparts.

Analysis shows that Asian companies will dominate the market. As early as 2011, 2,100 patent family applications related to electrochemical energy storage belonged to Asian developers; 530 belonged to European developers, and only 410 belonged to American developers. Despite the high initial numbers, applications from Asians have increased by 220% since 2001, while applications from Europeans have increased by 260% and Americans by 70%.

The report shows that if the quality of the investment portfolio is taken into account, Asian companies still occupy a very important position. The researchers used an index that took into account both quantitative data and the number of application citations. According to this index, the top ten in the lithium-ion battery field include 8 Japanese companies and 1 Korean company, with Fujifilm leading the way. Only one American company, Valence Technology, made the list. Europe's most successful institution, the Center National de la Recherche Scientifique (CNRS), ranks only 25th.

Isabell M. serves as chairman of strategy and organization. Professor Welpe said: "These results raise interesting questions about research policy and development management. For example, further research could examine what strategies have enabled certain companies to achieve technological leadership in this area, and where European and US rivals may have derived it from What lessons have been learned.”

The research is part of the EEBatt project, which focuses on decentralized stationary battery energy storage to enable the efficient use of renewable energy and support grid stability. The project is funded by the Bavarian Ministry of Economic Affairs and Media, Energy and Technology and is run jointly by TUM, the Bavaria Institute for Applied Energy Research (ZAEBayern) and VARTAStorage GmbH.
