Why are there more and more new energy vehicles? Detailed explanation of the technological development path of LR6 alkaline battery!

　　Prospects are divided into new Yang Hong. Information technology is developing rapidly at home and abroad. The information and communication industry has become one of the pillar industries of national economy and social development. This has also greatly promoted the development of new green battery technology and its industrialization process.

　　As batteries for communications, the following new green battery technologies and related industries have developed particularly rapidly: hydrogen storage materials and metal hydride nickel batteries lithium ion embedded materials and liquid electrolytes lithium ion batteries polymer electrolyte lithium batteries or lithium ion batteries zinc air batteries In 2001, Japan's Nomura Co., Ltd. published a detailed survey report on the development and prospects of new green batteries in the world of Japanese fuel cells. It showed that from April 1999 to March 2000, the world's primary battery and storage battery market totaled US$28.5 billion. , of which the total primary battery market is US$100 million, the total lead-acid battery market is US$800 million, and the total small battery market is also US$6.5 billion. At the same time, it is clearly pointed out that in the small battery market, the growth of new metal hydride nickel lithium-ion batteries and polymer lithium-ion batteries has tripled since the mid-1990s, and will continue to rise. This is also related to the continued increase in the proportion of their application in mobile phones. The research direction of small battery applications continues to look for new materials to further improve battery performance and reduce battery costs. Now used in most battery products, 3, 2. There are also a small number of products called Japanese Moli square batteries that have begun to be used. 8, 0.2, 2 and 2, 4 are substituted. The former can increase the specific energy of the battery, while the latter can reduce the cost of the battery. There are many kinds of negative electrode materials. Recently, it has been found that natural graphite is not only affordable, but also can reach a very high temperature. The high specific volume and low capacity loss are reduced from the original 6 to less than 4. In addition, research on electrolyte materials and separator materials continues.

　　Product performance continues to improve, product specifications and varieties continue to increase, and application fields continue to expand. As mobile phones become smaller and smaller, small prismatic batteries are favored. In order to reduce weight, Nippon Yang's prismatic batteries have adopted aluminum casings and solved key technical problems such as series sealing and welding. At the same time, with the application of new materials and optimized battery design, the specific energy of lithium-ion batteries has increased from the initial level to more than 150. Among them, the capacity of the 18650 batteries produced by various Japanese companies has reached 1800 ㎡, and the products developed have reached 2000 ㎡. At the same time, the thickness of the square battery is 3.8 ㎡, and its weight and volume specific energy have reached 60 ㎡ and 360 ㎡ respectively. The battery is apparently a competitor to polymer lithium-ion batteries.

　　The development and application market status and prospects of my country's new green batteries. Since the 1990s, my country has increasingly become the world's largest battery producer and largest battery consumer. According to statistics, by the end of 1999, my country's annual battery output reached 14 billion, of which Domestic consumption is 6 billion, with an average of 5 per capita. By the end of 2000, my country's annual battery production increased to 17 billion units, domestic consumption increased to 7 billion units, and per capita consumption reached 6.6 units. Already used, the following analysis of batteries for mobile phones and cordless phones is in rapid growth.

　　1. China’s primary battery industry Before 1998, most of my country’s automated alkaline zinc-manganese battery assembly lines were imported. On January 8, 1998, the first domestic 86-type alkaline zinc-manganese battery production line was completed at Xinda Company in Ningbo. This production line has been improved and innovated in appearance material selection process and electronic control. It has reached the international advanced level of imported equipment in the 1990s. Recently, Nanfu Company, my country's largest alkaline zinc-manganese battery manufacturer, designed and manufactured an LR6 series automatic assembly line, with a maximum speed of 400 units, and won the 2001 National High-tech Progress Award through preliminary evaluation.

　　The company's output in 2000 was 450 million, an increase of 50% compared with 1999. This productivity has ranked among the world's largest alkaline battery manufacturers. 14, 16, 03, 61 and 1 series products.

　　2. my country's metal hydride nickel battery and lithium-ion battery industry my country's new metal hydride nickel industry was developed under the promotion of the 863 plan. At present, domestic companies that have formed large-scale production capabilities include Tianjin Peace Bay Company, Tianjin Blue Sky Ocean Company, and Tianjin Tianjin Company, Guangdong Province Taiyi Company and Jiali Company, Liaoning Province Pu Company, Jiangsu Qidong Company and Zhejiang Zhongda Company, etc. Among them, the annual production capacity of Peace Bay metal hydride nickel batteries is 40 million units. The main production equipment and technology are provided by Japan's former Toshiba The nominal capacity of the type 6 batteries introduced by the company and currently produced is 600 ㎡. The nominal capacity of the type 6 batteries will increase to 700 ㎡ in the near future. In addition, it also produces prismatic 6-cell batteries and other products. These products are mainly used in mobile phones. From the current situation and development forecast of domestic and foreign mobile phone and notebook computer technology markets, it can be seen that from the perspective of my country’s mobile phone market, it is expected that the annual production of mobile phones in my country will reach 70 million units this year, and mobile phone users will The number of households increased from 70 million at the end of last year to more than 120 million. Therefore, the demand for new lithium-ion batteries is very large, which brings good opportunities to the development of my country's new battery industry.
