Once a dream, now reality: the Solar Energy Industries Association (SEIA) reports in its Solar & Storage Supply Chain Dashboard that the entire solar supply chain has been reshored, from polysilicon refinement to module assembly, and U. manufacturing capacity has grown. U. Manufacturing Renaissance Driven by Policy Support: American solar manufacturing has reached a critical milestone in 2025, with domestic factories now capable of producing enough panels to meet nearly all U. 🡥 This reliance on imports raises concerns about energy security, economic resilience, and the sustainability. Solar panel production is heavily concentrated in a small group of countries, particularly in Asia. In reality, the most consistent, comparable global series is published with a lag. solar manufacturing pipeline is robust, however, Trump Administration policies, regulations and trade actions could stall progress and dampen demand for U.

Despite the Covid-19 crisis, patenting activity on solid-state Li-ion batteriescontinued to grow in 2022, strongly driven by important patent applications in China filed by not only Chinese patent a. In 2022, more than 320 new patent applicants entered the solid-state Li-ion battery–related patent landscape, with three-quarters filing only one patent family (i.e., unique inve. Several non-Chinese startups incorporated after 2016 entered the solid-state Li-ion battery patent landscape in 2022, mainly originating from South Korea and the U.S. Even though most Japanese companies had started filing patents on solid-state batteries many years earlier, some of them only joined the IP landscape in 2022, such as material manu. Several South Korean material manufacturers entered the patent landscape in 2022 (i.e., their first solid-state battery-related patent was published in 2022). Kolon Ind.
[PDF Version]To be very clear: This especially means that the lithium-ion battery category does not contain any patent families tagged as solid-state battery inventions. The fourth step's purpose was to add patent data related to redox-flow and nickel–hydrogen batteries to the dataset.
Currently, more than 4,000 patents have been granted, mainly in Japan and China, and more than 3,600 patent applications are pending, mainly in the USA and China. More than 590 patent applicants can be found on the NMC Lithium-ion Battery patent landscape.
Kittner et al. and Ziegler and Trancik employed the patent proxy in their efforts to model the forces driving the prices of lithium-ion batteries, and found that cumulative patent filings is the best predictor of real prices scaled by energy capacity.
In 2022, more than 320 new patent applicants entered the solid-state Li-ion battery–related patent landscape, with three-quarters filing only one patent family (i.e., unique invention). Most of these IP newcomers are Chinese companies and R&D labs, with less than 30% of them publishing more than one patent family that year.
Their patent output related to lead–acid batteries is the lowest of the three clusters and their sodium-ion-related IPF share is close to zero. This cluster contains high-tech industrial nations like the US, Germany, and Taiwan, countries that are known to have explicitly expressed their ambitions in the field of battery technology.
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.
