The increase in energy density and weight reduction of lithium batteries are the key to future expansion of demand. Especially in recent years, the market for "gadgets" for ordinary consumers that can perform multitasking has expanded, which has increased the demand for lithium batteries with high energy density and low weight.

　　Industry analysts pointed out that in addition to traditional main applications such as notebook computers and mobile phones, new applications such as electric hardware tools, other consumer electronics, light electric vehicles and electric vehicles have injected high growth momentum into lithium batteries and will become 2016 The annual total output value of lithium batteries is the main driver of the challenge of 10 billion US dollars. The rise of the aforementioned emerging applications, in addition to accelerating the expansion of demand for lithium batteries, will also help the lithium battery industry escape the single industry cycle of consumer electronics such as notebook computers and mobile phones.

　　From the perspective of the supply of products of different shapes, 46% of the cylindrical shape, 41% of the square shape, and 13% of the polymer shape (containing aluminum shell batteries). There are 4 or 6 more cylindrical batteries in laptop batteries. A new market for power tools is forming, and each machine is also equipped with multiple batteries. In terms of prismatic batteries, mobile phones, especially low-priced models supplied to emerging market countries, have played a driving role. Sales of lithium-ion polymer batteries, centered on mobile phones, are increasing.

　　"2015-2020 China Lithium Battery Industry Market Survey Research Report" shows that from the perspective of different uses, 49% for mobile phones, 36% for laptops, and 4% for digital cameras.

　　my country’s lithium battery industry accounts for a large proportion of low-tech products, which are far from being able to meet the needs of all downstream sectors. Some high-end products with special functions are currently mainly dependent on imports.

　　In addition, one of the biggest problems in domestic development is duplication of construction. When a new product or new technology comes out, it will soon imitate each other and compete with each other. In a short period of time, there will be oversupply and competition with lower prices. Generally speaking, there is still a certain gap between my country's lithium batteries and developed countries in terms of overall technical level, innovation level, equipment level and management level.
