1. Regional competition pattern of global energy storage battery technology
(1) Distribution of technology source countries: China accounts for the highest proportion
Currently, the largest technology source country for energy storage batteries in the world is China, and China’s energy storage battery patent applications account for the largest share of global energy storage It accounts for 67.56% of the total battery patent applications; followed by the United States, which accounts for 6.19% of the total global energy storage battery patent applications. Although the United States, Japan and South Korea rank second, third and fourth, there is a large gap between the number of patent applications in China and China, which ranks first.
Statistical instructions: ① Statistics are based on the deduplication rule of displaying one public text for each application, and the latest text on the public date is selected for calculation. ② Statistics are based on the country of patent priority. If there is no priority, calculation is based on the country of the receiving office. If there are multiple priority countries, the earliest priority country will be used.
(2) Patent application trends: China overtook the United States and Europe in 2016
From a trend perspective, from 2010 to 2015, the United States and the European Patent Office were far ahead in the number of energy storage battery patent applications, but they were overtaken by China after 2016. In 2020, there were 5,520 energy storage battery patent applications in China, 589 energy storage battery patent applications in the United States, and 110 energy storage battery patent applications in Europe.
Statistical instructions: ① Statistics are based on the deduplication rule of displaying one public text for each application, and the latest text on the public date is selected for calculation. ② Statistics are based on the country of patent priority. If there is no priority, calculation is based on the country of the receiving office. If there are multiple priority countries, the earliest priority country will be used.
(3) Distribution of regional patent applications in China: Guangdong has been at the top of the list since 2015.
In China, Guangdong is the province with the largest number of energy storage battery patent applications in China, with a total of 2,347 energy storage battery patent applications. The number of energy storage battery patent applications currently applied for in Jiangsu, Beijing, Shanghai, and Zhejiang exceeds 1,000. Anhui, Shandong, Hubei, Hunan and Sichuan are currently among the top ten provinces in China that have applied for provincial (municipal, autonomous region) energy storage battery patents.
statistical caliber description: Statistics are based on the address submitted by the patent applicant.
In terms of trends, from 2010 to 2016, the number of energy storage battery patent applications in Guangdong, Jiangsu, and Beijing was basically the same. However, since 2017, Guangdong has gradually widened the distance from Beijing and has always ranked first. There is not much difference in the number of energy storage battery patent applications between Shanghai, Zhejiang, Anhui, Shandong and Hubei from 2010 to 2020.
statistical caliber description: Statistics are based on the address submitted by the patent applicant.
2. Competitive landscape of global energy storage battery technology applicants
(1) Concentration of patent applicants: market concentration is not high, CR10 fluctuations decrease
From 2010 to July 2021, global energy storage battery patent applicants CR10 showed a fluctuating downward trend. The fluctuation dropped from 86.11% in 2010 to 12.94% in July 2021. Overall, the concentration of global energy storage battery patent applicants is not high, and the concentration is showing a downward trend.
Statistical Caliber Description: Market Concentration - CR10 is the proportion of the patent applications of the top 10 applicants in the total number of applications to the total number of patent applications in the field (wherein, when there are joint applications, the number of patents will not be deduplicated calculate).
(2) Top 10 patent applicants
- Total amount and trend: State Grid Corporation of China takes the crown
The top 10 patent applicants in the global energy storage battery industry are State Grid Corporation of China, LG Chem Co., Ltd., and China Electric Power Research Institute Ltd., Robert Bosch GmbH, BMW AG, Jiangsu Electric Power Company, CATL New Energy Technology Co., Ltd., North China Electric Power University, General Motors Global Technology Operations Co., Ltd., and Tianjin University.
Among them, State Grid Corporation of China has the largest number of energy storage battery patent applications, with 1,175. LG Chem Co., Ltd. ranks second, with 510 energy storage battery patent applications.
Note: The number of joint applications has not been eliminated.
In terms of trends, from 2010 to 2017, there was not much difference in the number of energy storage battery patents applied by the top ten energy storage battery patent applicants in the world. Until 2018, the State Grid Corporation began to stand out. In 2020, the State Grid Corporation of China applied for energy storage battery patents. The number of patent applications for energy storage batteries reached 362, which is more than three times the number of energy storage battery patent applications of the second-ranked China Electric Power Research Institute Co., Ltd.
- Patent technology distribution: H01M10 subdivision has many layouts
At present, the technologies of the top 10 applicants in the global energy storage battery industry with the number of patent applications are mainly deployed in the H01M10 subdivision, among which the company ranks second in the world in terms of the number of energy storage battery patent applications. LG Chem has applied for 325 patents in this segment.
(3) Applicant of the TOP10 patents with the highest market value: Baymark Co., Ltd. has the highest patent value
Among the TOP10 patents with the highest market value for energy storage batteries in the world, Baymark Co., Ltd. has the highest patent value of US$8.48 million, and the rest have a market value of The highest TOP10 patents are as follows:
Note: The most valuable patents refer to the simple sibling with the highest patent value in the technical field. The current statistical caliber is based on the deduplication rule of one patent representative for each group of simple families, and any patent with patent value in the family is selected for display.
(4) New entrants in patent applications: Top ten new entrants
There are ten new entrants in the world, namely Xi'an Thermal Engineering Research Institute Co., Ltd., Shanghai Electric Power University Sungrow Power Supply Co., Ltd., Xi'an Jiaotong University, and Guangdong Power Grid Co., Ltd. Responsible Company, Southeast University, Zhejiang University, Nanjing Institute of Technology, Guangdong University of Technology, Zhejiang University of Technology, and these top ten new entrants will be more active in applying for energy storage battery patents in 2020. Among them, the number of energy storage battery patents applied by Xi'an Jiaotong University The maximum is 53 items.
New entrant definition: Applicants who have submitted patent applications only within the past 5 years.
