"Ni-MH batteries are a realistic choice, and lithium batteries are the development direction." Liu Jun, a researcher at Anxin Securities, said that the industrialization of lithium batteries will take time, and in the transition period of the next three to five years, the new energy power will also be nickel. Hydrogen batteries are the mainstay. According to the data, 90% of the global automotive battery market is dominated by nickel-metal hydride batteries, and Japan has the most core technologies. Nickel-metal hydride batteries have stable performance, mature technology and industrialization, and will become the key development direction of domestic new energy in the next five years. "From the perspective of commercial mass production, nickel-metal hydride batteries are indeed better than lithium batteries." Liu Jun said, but with the maturity of lithium battery technology, its market space will gradually be released in the future. At present, the whole market has a lot of discussion on the application prospects of lithium batteries in the field of new energy vehicles. However, there is little concern about its application prospects in the traditional field. Through careful study of the application of lithium batteries in the current main application areas, it is found that even if the development of new energy vehicles is lower than expected, the development prospects of the lithium battery industry are still optimistic.Currently, the notebook and mobile phone markets remain the two main markets for lithium batteries. In the future, the personalization and tableting trend of personal PCs will continue to drive the rapid growth of demand for lithium batteries. The smart phone and touch screen will also ensure a steady increase in shipments. And lithium batteries in the digital camera, PSP, e-books, power tools, electric bicycles and communication backup power supply and other fields in the field of "flowering everywhere" is also worth looking forward to. Through a summary analysis of the demand for lithium batteries, we found that in 2010, the total capacity of the global small lithium battery market is about 52.6 billion yuan. By 2015, this market capacity will reach 106.9 billion yuan, which is double the current. In the next five years, the average annual growth rate of the small lithium battery market will maintain a growth rate of around 15%. The subsequent development of small lithium batteries will provide solid support for the development of the lithium battery industry.
