Lithium polymer battery refers to the secondary battery, which uses lithium compound as anode and cathode material. In the charging and discharging process, lithium ion discharges and inserts back and forth between the two electrodes.
Compared with traditional lead-acid battery such as chromium and nickel batteries, lithium polymer batteries with high energy density, long cycle life, charge and discharge performance is good, the use of high voltage, no memory effect, less pollution and safety higher advantages, at the same time relative to the various types of fuel cells, air batteries and ultracapacitors batteries, lithium polymer battery technology mature.
In recent years, with the maturity of the process, the price gradually declined, the cost performance advantage is prominent. With excellent battery performance, environmental protection and price advantages, lithium polymer batteries continue to increase the market share in the battery industry.
Global lithium battery industry situation
With the rapid development of mobile devices, power tools, energy storage, etc., the global demand for lithium polymer batteries has grown rapidly and has driven the development of the lithium polymer industry.
In terms of market demand, according to Zhen Li Research, the market demand for lithium polymer batteries will continue to grow at a rapid annual growth rate of nearly 50% in the next five years.
2018, global demand will exceed 385 million kWh, which is 7 times over 2013, exceed the lead-acid battery to be the largest secondary battery product.
In terms of industrial scale, according to IIT statistics, from 2005 to 2013, the global lithium battery market grew from 5.6 billion US dollars to 14.1 billion US dollars, with a compound annual growth rate of 12.1%. It is estimated that the market scale will be 42.2 billion US dollars in 2022. The annual compound annual growth rate is expected to be 12.9%).
Lithium polymer battery industry situation in China
Lithium polymer battery market demand in China
Driven by national policies and downstream industries, the annual demand for lithium battery market in China from 2011 to 2014 was increased, with 44.79% in 2011, 67.26% in 2013, and a compound annual growth rate of 55.62% from 2011-2013. It is estimated to be more than 60% in 2014(Figure 3). Among them, the driving force for market growth in 2013 mainly came from smartphones, mobile power supplies, electric bicycles, etc. In addition to the above markets, the biggest driving force in 2014 came from electric vehicles and base station power supplies. Moreover, in the global market demand, the proportion of the Chinese market has also risen rapidly. In 2011 and 2012, it was between 17% and 18%. In 2013, it quickly rose to 21.5% (25%). The proportion in 2014 is still rising.
Lithium polymer battery production and industrial scale in China
The rapid growth of market demand has led to an increase in the production of domestic lithium batteries and an expanding industrial scale. In terms of production, according to AskCIData data, China’s lithium battery production in 2014 reached 5.28 billion pcs, an increase of 10.9% compared with last year. From 2010 to 2014, China’s lithium battery production continued to grow substantially, with growth rates above 10%.
In terms of industrial scale, according to CCM data, in 2014, the market size of the lithium polymer battery was 71.5 billion yuan, up 21.1% year-on-year. Among them, lithium polymer batteries in the 3C market grew by 6%, and the national sales scale was 58 billion yuan. Energy storage lithium polymer batteries, including communications and new energy applications, demand scale 1.5 billion yuan. In 2018, the lithium polymer battery industry surge to 400%, reaching 20 billion Ah, more than twice the global capacity in 2013.
