Explain the development status of large-capacity lithium battery energy storage systems at home and abroad in detail

The total capacity of the lithium battery energy storage market is considerable, and the potential for the user side is huge. The installed capacity of new energy will contribute 90% of the increase in energy consumption. The power of the supporting energy storage device is calculated based on 15% of the installed capacity of wind power and photovoltaics. By 2030, the demand for energy storage lithium batteries is expected to reach 850 million kWh, in kilowatt-hours. Calculating the price of energy storage system (lithium battery) at 1,200 yuan, China's wind and solar energy storage market space is expected to reach 1 trillion yuan (RMB). According to the current application scope, the three major categories of lithium battery energy storage are: large-scale wind and solar energy storage, Backup power supply for communication base stations and home energy storage. Among them, the backup power supply of communication base stations currently accounts for a large proportion. With the wave of energy households set off by Tesla, household energy storage has more room for further development and expansion. Large-scale wind and solar energy storage does not seem to have a strong momentum in a short time. Under the guidance of policies, the domestic lithium battery market has continued to expand. In detail, driven by the rapid rise of the new energy vehicle market, my country's new energy vehicle power lithium battery market has developed rapidly, with output rising from 1.2GWh in 2012 to 44.5GWh in 2017, and is expected to be around 70GWh in 2019. In terms of energy storage lithium batteries, in the next 5 years, my country's energy storage lithium battery industry will enter a growth period with great market potential. In the emerging energy Internet, due to the large-scale access of renewable energy and distributed energy in the large grid, combined with the popular use of micro-grid and electric vehicles, energy storage technology will be a crucial part of coordinating these uses. , The energy storage link will become the key node of the entire energy Internet; the rise of the energy Internet will significantly drive the demand for energy storage. The rapid progress of lithium battery processing technology has reduced the cost of lithium battery products, which will enhance the competitiveness of energy storage lithium battery products compared to other energy storage technologies. The market penetration rate of lithium batteries in the field of energy storage is gradually increasing, which will further promote the use of the market. The scale has risen accordingly. It is estimated that by 2022, the output value of my country's lithium battery energy storage will increase to 13.7 billion yuan. Compared with traditional batteries, lithium batteries have the advantages of high energy density, high working voltage, light weight, small size, small self-discharge, no memory effect, long cycle life, fast charging, etc. At the same time, because they do not contain heavy metals such as lead and cadmium, there is no Polluting and non-toxic materials, it is widely used in consumer electronic products such as smart phones, notebooks, and tablets, as well as new energy vehicles and energy storage. Battery cost and lithium battery energy storage technology limit the further large-scale use of battery energy storage in the grid. In terms of technology, the inconsistency and short-board effect of the battery limit the scale of battery series and parallel connection, resulting in the inability to achieve large-scale use of battery energy storage through simple electrical connections. On the other hand, in the scenario of large-scale battery energy storage, the consistency of a large number of energy storage batteries is bound to be more significant due to different batches, different aging characteristics, use time, operating environment, and even different manufacturers.
