Prospects for the Development of Lithium Batteries.best rv deep cycle battery

　　Analysis suggests that in the next few years, Japan will lead the United States, Europe, and other countries in intellectual property competition in the field of new energy vehicles. However, due to the rapid growth of the new energy vehicle industry and the lack of mature solutions for many key technologies, the United States and Europe, relying on their strong basic research advantages, are highly likely to make breakthroughs in certain key technologies and regain competitive advantages. In addition, rising stars in the automotive industry such as South Korea and China are continuously increasing their investment in the research and development of new energy vehicles, which can be expected to make the competitive landscape of new energy vehicles more complex in the future.

　　At present, the research on battery for pure new energy vehicles in Japan mainly focuses on lithium battery, followed by lead-acid battery, Nickel–metal hydride battery and sodium battery. From the total number of patent applications worldwide, Japan has the highest number of patent applications related to pure new energy vehicle batteries and their management systems. From the domestic patent application volume in Japan, over 90% of patent applications also come from Japanese applicants. Whether from the perspective of the ownership of world patent applications or the share of Japanese applicants in Japanese patent applications, Japan is the strongest in the field of pure new energy vehicle batteries and their management systems, controlling the vast majority of patented technologies.

　　As the largest automobile production and consumption country in the world, the research on batteries for pure new energy vehicles in the United States mainly focuses on lithium batteries. The number of patents related to lithium batteries accounts for more than 70% of the number of power battery patents, followed by lead-acid batteries, Nickel–metal hydride battery, air batteries and sodium batteries. From the total number of patent applications worldwide, as of June 2010, the United States ranked second in the number of patent applications related to pure new energy vehicle batteries and their management systems after Japan. From the perspective of domestic patent applications in the United States, among patent applications related to pure new energy vehicle batteries and their management systems, Japanese applicants have the highest number of patents, accounting for nearly 60% of the total, while the number of patent applications from American applicants is second to Japan.

　　The research of pure new energy automotive batteries in Germany mainly focuses on lithium batteries, followed by lead-acid batteries, Nickel–metal hydride battery, sodium batteries and air batteries. From the total number of patent applications worldwide, as of June 2010, Germany ranked 6th in the world in the number of patent applications related to pure new energy vehicle batteries and their management systems, which is significantly different from the number of Japanese patents ranked first, accounting for only 11% of Japan's patent applications. From the perspective of domestic patent applications in Germany, German applicants hold about 43% of the total number of patents, higher than Japan, which ranks second. On a global scale, Germany's technological strength in the field of pure new energy vehicle batteries and management systems is far inferior to that of Japan. However, within its own country, Germany has a strong technological advantage, with a higher patent ownership than Japan.
