The metrics of battery development: patenting patterns since 2000
| Resumo: | This study provides a technometric analysis of patent activity on secondary battery technologies from 2000 to 2019. Its goal is to enrich and bolster the existing literature on the topic by providing a deeper insight into how inventive dynamics in this field have been evolving. The research deeply explores which technologies and concepts are emerging, declining, or becoming established, both in absolute and in relative terms. We also delve into how geographic locations can be characterized in terms of their position in the technology space. Mapping and measuring battery progress is relevant as this technology is a capstone at the current intersection of energy and digital transitions. Worldwide battery patent counts are assembled and broken down alongside time, territory, and technological dimensions. We took international patent families as an indicator and extracted 92,700 patents from the PATSTAT database, which is the empirical source for this study. We found that global battery patenting activity had trended upwards in 2000-2019, the majority of battery patents originated from Asia, and that several Asian and European countries exhibited high battery patent intensities in the given timeframe. Comparing the two decades of 2000-2009 and 2010-2019, a considerable increase in yearly battery patenting activity was observed. We found that four battery types (redox flow, solid-state, sodium-ion, and lithium-sulfur) have displayed marked progress in recent years. Furthermore, countries can be clustered in a meaningful way using their patenting performance across these four emerging battery types and the already established lead-acid technology. Moreover, several other battery-related technologies such as energy storage systems, battery management systems, wireless power transmission, electric vehicle charging, and uncrewed aerial vehicles (i.e., drones) are growing in relevance. |
