Lithium-ion battery breakthrough in energy storage

With the development of society, China's demand for energy continues to grow. Foreign countries attach great importance to the research and development of large-scale energy storage systems. China also attaches great importance to the development of energy storage technology, and focuses on energy storage technology. Energy storage technology is developing in the direction of large-scale, high-efficiency, long-life, low-cost, and non-polluting. In this process, battery energy storage technology is of great significance.

First, lithium ion battery energy storage

So far, various energy storage technologies have been proposed and developed to meet the needs of different fields and different needs. Lithium-ion battery energy storage is currently the most feasible technical route.

Lithium-ion batteries are known as green batteries because of their high energy density, low self-discharge, high safety performance, no memory effect, wide operating temperature range, fast charge and discharge, long service life and no environmental pollution. Currently, lithium-ion batteries, mainly lithium iron phosphate, lithium titanate and lithium manganate are used in the field of smart grids.

The lithium iron phosphate battery has relatively high energy density and strong endurance. With the application of lithium iron phosphate cathode material, the life and safety of the traditional carbon anode lithium ion battery have been greatly improved, and it is preferred in the field of energy storage.

Lithium titanate has a long cycle life, and in the future, the advantages of relatively low energy density, weak endurance and high price make the application of lithium titanate battery in the field of energy storage possible.

The lithium manganate battery has good rate performance, is easy to prepare, and has advantages such as improved high temperature performance and poor cycle performance in the future, which is more conducive to application in the field of energy storage.

Second, the market prospects of lithium-ion battery energy storage technology

Since 2015, the global lithium battery energy storage system is technically much higher than other battery energy storage systems, and lithium-ion batteries will become the mainstream of future energy storage. Statistics show that in 2016, lithium-ion batteries accounted for 50% of new energy storage solutions. In 2020, the market for energy storage batteries will reach 70 billion yuan. By 2025, lithium-ion batteries are expected to continue to dominate, accounting for 80% of global power battery storage deployments.

Driven by national policies, the demand for lithium batteries in the energy storage field is also growing rapidly. By 2018, the cumulative demand for energy storage lithium-ion batteries has reached 13.66Gwh, which has become a follow-up force to promote the growth of the lithium battery market.

Due to the continuous maturity and innovation of new materials development and production technology of lithium-ion batteries, and the active participation of relevant scientific research institutions and industries, lithium-ion batteries have significant advantages such as high specific energy, long cycle life and green environmental protection at low cost. It has become the main supporting power source for all kinds of advanced energy storage products.

Since 2015, a number of specialized energy storage companies have been established in China, and the planned storage capacity has exceeded 100,000 kilowatts. At present, the global annual demand for lithium-ion batteries has reached 1.3 billion, with annual sales of 27 billion US dollars. Lithium-ion batteries are undoubtedly the mainstream technology route for the future.

With the continuous development and application of lithium-ion batteries, it will become an ideal choice for a series of major high-tech applications such as energy storage.
