do you know how many pcs of lithium ion batteries would be used per year all over the world?
In terms of large secondary batteries, environmental protection and resource issues have become global topics in the 21st century. Although the demand for secondary batteries in the electric vehicle/motorcycle/bicycle industry is still in the embryonic stage, all countries are optimistic about the market potential in the future.
In terms of small secondary batteries, with the liberalization of the global telecom market, the rapid growth of the communications market and the increase in production of notebook computer information products, the demand for various types of small secondary batteries will be greatly expanded. It is predicted that the utilization rate of ni-mh batteries will decrease year by year due to environmental problems in the future, while the demand of ni-mh batteries and filing ion batteries will keep increasing due to the light, thin, short and small development trend of communication/information products.
At present, the Japanese manufacturers that have already invested in the production of lithium ion secondary battery include SONY, panasonic battery, sanyo motor, ATBattery, Hitachi Maxell, Japanese battery, Japan Moli and Fuji photo film and so on. There's also Moli of Canada. It is reported that the United States, France, Singapore, South Korea and other relevant enterprises will also be involved in this production field, especially noteworthy that the south Korean government or private enterprises are very active in the research and development of ionic rechargeable batteries, with the involvement of large consortiums, its development is worthy of attention. South Korea's biggest feature is finding foreign companies to work with to quickly build up its production capacity through technology introduction. The future development of potassium ion battery can be discussed from three aspects: positive pole, negative pole and electrolyte.
In the development of secondary lithium polymer battery. Because electrolyte belongs to high polymer. Therefore, high safety, long life and plasticity can be made into various shapes according to product requirements. However, there are some technical problems to be overcome in terms of electrolyte conductivity, electrode and stability of electrolyte interface.
take the new energy car for an example, 2017, the world's top 10 new energy car sales volumn reaches 441940 all over the world. each new energy car should use average 3000-4000pcs li ion battery cell, that is, 1,325,820,000 pcs lithium ion battery cell per year,
