my country's battery technology international patents rank among the top four

A report published by the European Patent Office and the International Energy Agency on September 22 showed that my country's battery patent ranking has risen to fourth in the world, behind Japan, South Korea and Europe. In 2019, my country's electric vehicle sales reached 1.1 million, accounting for half of the world. The report shows that between 2005 and 2018, the global patents for batteries and other power storage technologies increased at an average annual rate of 14%. In 2018, more than 7,000 international patent families related to power storage were announced, far exceeding 1,000 in 2000. Nearly 90% of the patents aim to improve power storage and promote battery performance, especially lithium batteries used in consumer electronics and electric vehicles. In 2018, lithium battery innovation accounted for 45% of battery patent activity. The report pointed out that in the field of lithium batteries, my country has become one of the four major innovation powers. From 2014 to 2018, my country's patent applications in the field of lithium batteries accounted for 9% of the world's total. In the past ten years, my country has become a strong promoter of battery technology innovation. Since 2018, the number of patent applications in my country has increased significantly. In 2011, my country sold 5,000 electric vehicles, accounting for 11% of the global electric vehicle market. In 2019, my country's total sales of electric vehicles reached 1.1 million, and its share jumped to 50% of the global market. Fatih Birol, executive director of the International Energy Agency, said that energy storage will increase exponentially in the next few decades, which will help achieve global emissions reduction and sustainable development goals. Research shows that thanks to technological progress and economies of scale, battery prices have fallen sharply in recent years. Among them, lithium batteries for electric vehicles have dropped by nearly 90% since 2010, and fixed usage costs, including grid management, have dropped by approximately in the same period. Two thirds. With the further development of the technical potential of battery secondary utilization, the cost will be further reduced by 2040, and the battery price will be 70% cheaper than today.
