This joint study by the International Energy Agency and European Patent Office underlines the key role that battery innovation is playing in the transition to clean energy technologies. It provides global data and analysis based on the international patent families filed in the field of electricity storage since 2000 (over 65 000 in total). It
the evidence on the role of patents for innovation and international technology transfer in general. The literature suggests that patent protection in a host country encourages technology transfer to that country but that its impact on innovation and development is much more ambiguous. We then discuss the implications of these findings and other technology-specific evidence for the

2002 – Various patents are filed on nanomate-rials used in lithium and other batter-ies to achieve increases in charge and discharge rates of 10 to 100 times. 2002 – Commercialization of solid state lith-ium polymer thin film batteries based on patents from ORNL. 2003 – Teeters, Korzhova and Fisher, working at the University of Tulsa in the USA, patent the
Downloadable (with restrictions)! Battery electric vehicles (BEVs) have been in the fourth wave of the low emission vehicle development since 2006. Moreover, the BEV technology diffusion is beyond national boundaries due to the changes in the innovation mode and product characteristics. The paper adopts priority patent applications and international patent families
Battery advances so far suggest incomplete circular transition. This analysis of over 90,000 secondary battery innovations (measured by international patent families) provides a comprehensive account of the long-run progress of a knowledge base with a key role in the transition to a transformative, closed-loop, Circular Economy.
The battery sector itself also presents new business opportunities as an emerging technology area, evidenced by the strong growth of the annual patent applications, which rose from 424 to
The global pursuit of efficient, safe, and high-energy-density batteries has led to significant interest in solid-state battery (SSB) technologies. SSBs promise numerous advantages over traditional liquid electrolyte-based lithium-ion batteries (LIBs), including improved safety due to reduced flammability, higher energy densities, and better
Through an inductive, multi-case approach looking at light-emitting diodes and lithium-ion secondary battery technology, we expand prior intellectual property modularity to incorporate internationalization effects across borders. Relying on patent classifications, we trace the development of these two technologies and key multinational
This study provides a comprehensive analysis of global patent trends in battery recycling, focusing on secondary batteries and related technologies across Korea, China, and the United States. The methodology involved collecting data from various patent databases, followed by quantitative analysis to identify technology trends and guide future
As the drive towards renewable energy use gains pace, there has been an increase in global patent filings relating to battery technology. While lithium-ion batteries currently dominate the battery market, they have several

The paper adopts priority patent applications and international patent families to map the BEV transnational technology diffusion from the perspective of global technology
The core of technology commercialization is patent transfers (Choi et al., 2015). When a granted patent is deemed to bring commercial value, someone will buy it from the patent inventor or owner (Jeong et al., 2013; Kwon, 2020; Maurseth and Svensson, 2020). On the other hand, this paper combines the inventors and assignees'' information in

Mitsubishi Gas Chemical Co is focusing on ion conductors containing LiCB 9 H 10 and LiCB 11 H 12 (International patent application 2020040044 (27/02/2020)). Where next for battery technology? It seems likely that the next big move by innovators will be towards solid state batteries. Solid anodes, cathodes and electrolytes are potentially safer
The paper adopts priority patent applications and international patent families to map the BEV transnational technology diffusion from the perspective of global technology innovation (GTI). Our study finds the sources and recipients of BEV technology are concentrated in a few countries or regions, while the transnational technology diffusion is
Conclusions This study conducted a comprehensive global patent analysis on battery recycling technologies, focusing on secondary batteries across Korea, China, and the United States. The findings reveal significant differences in patent activities and technological focuses among these countries.
We find that global battery patenting activity grew significantly in the 2000–2019 period. This stylized fact means that the comparative advantages of secondary approaches (rechargeable, redeployable, reusable batteries) have been continuously on the rise driven by innovation, making a direct contribution to socio-technical circularity.
The majority of battery patents are found to originate in Asia while high battery patent intensities are revealed in the performance of several Asian and European countries. Overall, a considerable increase in annual battery patenting activity is observed from 2000–2009 to 2010–2019.
Given the IPF constraint deployed for this study and the IEA and EPO report , these solely nationally filed applications are not considered in either one. In fact, in the current study’s dataset, IPFs make up only 19.4% of all battery patent families.
Based on the information available, the battery technology patent race is intensifying among South Korea, China, and the USA, with significant developments and strategic moves observed in each country .
As such, the market and technology for battery recycling in Korea, China, and the United States are fully expanding. However, it is not easy to find a paper that analyzes in-depth battery recycling patents in Korea, China, and the United States.
