The development of battery industry and application were reviewed

Source: 2020 - 04 - 6: now click traffic time battery industry are reviewed in this paper the development and application of summary: China has gone from focus on economic development gradually transition to the economy, society and nature coordination development stage, from the aspect of national policy and the ideology of people pay more and more attention to environmental protection. In this background, the development of battery technology is not only to meet the growing market demand, more to realize its own technological revolution, toward the high-energy, large capacity, lightweight, unified, long life, intelligent direction. Lead-acid battery as of December 2013, the Ministry of Commerce and industry registration, lead-acid battery production enterprise's qualification of nearly 2000, more than 1800 people have a production license, 17 company annual sales income over 1 billion yuan, staff more than 2 million, for the whole industry chain directly engaged in lead-acid battery production, sales and management staff have close to 200000. From the perspective of the lead-acid battery industry, according to analysis of industry association statistics, in 2013 the industry's total sales income is 112 billion yuan, up 9% from a year earlier, accounts for two-thirds of the total sales revenue of battery industry, its main products are chemical electric power industry. 2, alkaline batteries, alkaline batteries is a battery with KOH aqueous solution as the electrolyte, its shape is square, flat shape, etc. , voltage stability, small impedance, high energy, temperature and wide range of advantages, so in railway, electric tools, aerospace, electronics and other fields often can see the figure of alkaline batteries. Three, lithium ion battery Japan, China and South Korea is the world's top three lithium ion battery producer, accounts for about 95% of global production. The positive material of the lithium ion battery using different source of lithium, main material is still the lithium cobalt oxide ( LiCoO2) 。 Different anode materials is not only the cost is different, and the working voltage of the battery, electrical, and safety are also different. Lithium ion secondary battery for the high output voltage and the advantages of larger than can, long cycle life become a new force in the field of battery. Especially in the current commercial rechargeable batteries, polymer lithium ion battery than the highest energy density, can realize the thickness of the rechargeable battery. Lithium ion battery is mainly used in mobile phones, electronic products, such as lithium ion batteries due to domestic has not yet formed a mature industry standards, many manufacturers products lack of consistency, plus the laptop security requirement is higher, this makes the domestic market share of laptop battery is relatively small, there are a lot of potential. Zinc manganese battery zinc manganese dry cell production in China has been the first in the world. Ordinary zinc manganese battery a large number of exports to the Middle East, Africa and other regions, alkaline zinc manganese battery a large number of exports to the United States, Europe and other regions. Zinc manganese battery grows steadily, and sales income is 19. 4 billion yuan in 2011, eight in zinc manganese battery year-on-year growth. 7%, compared with 10 alkaline manganese batteries. 6%, accounting for 13 battery sales income in China. 3%. In the modern society, with the rapid development of information technology, digital products become an indispensable part of people's life, as a kind of digital product the product power supply zinc manganese battery development prospect will be broader, will continue to continue its long glorious history. Five, the conclusion from the focus on the economic development of our country, and gradually transition to the economy, society and nature coordinated development stage, from the national policy level and people's ideology, more and more attention to environmental protection, in this context, also promoted the development of battery technology, to meet the growing market demand, should also be aware of their technology revolution, high energy, high capacity, is a, unification, long life, intelligent direction. At present, the development of battery industry displays the following main characteristics: first, pay attention to environmental protection concept; 2 it is to implement the concept of sustainable development, a battery out of the market gradually, the application of the battery is more and more widely; Third, the structure of the battery are smaller, lighter, thinner.
