Lithium ion battery (Lithium-ion Battery,LIB) as a secondary battery (rechargeable battery) representative, is currently more widely used battery. Lithium-ion batteries are usually composed of a positive electrode, a negative electrode, a separator, an electrolyte, a shell, etc. During cycling, lithium ions are inserted and removed between the positive electrode and the negative electrode through the internal circuit, and the back and forth of electrons in the external circuit to achieve charging and discharging. According to the cathode material, packaging and use can be classified, lithium ion battery in the long-term charge and discharge cycle, the internal will produce a series of side reactions, including lithium evolution, solid electrolyte interface (SEI) film growth, reduce the capacity of the battery, when the battery capacity is reduced to 80% of the initial capacity, that is defined as the end of the battery life. It is characterized by high specific energy, long life, high working voltage, wide operating temperature range, no memory effect, low self-discharge and environmental friendliness, so it is widely used in new energy vehicles, power grid energy storage and portable electronic equipment.

Advantages and disadvantages of lithium batteries
High working voltage: The working voltage of lithium-ion batteries is as high as 3.6V, which is 3 times that of nickel-chromium and nickel-hydrogen batteries, and 2 times that of lead-acid batteries. High energy density: Lithium-ion batteries have high working voltage and low lithium density, so the mass energy density (200Wh/kg) and volumetric energy density (350Wh/L) of lithium-ion batteries are very large, which is 3 times that of lead-acid batteries (50-70Wh/kg).

The development trend of lithium battery
As a region with more active development of lithium-ion batteries in the world, the market scale of lithium-ion batteries is increasing year by year. New energy vehicles are the larger engines driving the rapid growth of lithium-ion batteries. The demand for lithium-ion batteries in the energy storage market is also expected to accelerate. In addition to meeting domestic demand, it will also be exported to Europe, America, Australia, Southeast Asia and other places in batches.

Long-term energy storage demand outbreak of lithium battery mainstream status challenges (I)
With the development of new energy, the trillion-level energy storage track presents a thriving scene. However, just as the outside world is amazed by the "prosperity" of the energy storage market, companies in the industry are beginning to worry about the upcoming "knockout" of the industry. Under the background of "double carbon", with the continuous advancement of energy transformation, the new energy storage industry has ushered in explosive development opportunities. It is estimated that by 2025, the market size will exceed one trillion yuan.

Long-term energy storage demand outbreak lithium battery mainstream status challenges (II)
However, under the huge demand for long-term energy storage, the lithium battery energy storage route, which is now the mainstream energy storage route, may face challenges in its "dominant" market position. On May 29, Zheng Xiaohao told the 21st Century Business Herald reporter that with the increasing demand for long-term storage, although the lithium battery route still has huge economic advantages at the moment, in the long run, its dominant position may be more suitable for long-term storage such as liquid flow. The technical route replaces. The liquid flow energy storage technology co., ltd. where he works is currently a domestic energy storage company that adopts the dual technical routes of all-vanadium flow battery and iron-chromium flow battery.
