In 2022, shipments of lithium batteries for energy storage rised
According to research data from the GGII, the shipment of lithium-ion batteries for energy storage in 2022 continued the strong growth momentum of the previous year, with the annual shipment reaching 130GWh, a year-on-year increase of 170.8%.
From the perspective of segmented tracks, the shipments of electric energy storage, home battery storage, and portable power station have climbed. Among them, the shipment of home battery storage grew the fastest, with a growth rate of over 3.5 times, and the growth rate of electric energy storage and portable energy storage both exceeded 2 times, when the communication energy storage batteries has slowed down, and had a negative growth in 2022, a year-on-year decrease of 25%.
According to GGII analysis, there are three main drivers of rapid market growth in 2022: 1) the European energy crisis caused by the geopolitical conflict between Russia and Ukraine; 2) China’s power market reform; 3) the power grid security crisis in some parts of the United States and the latest policy subsidy plan.
Electric energy storage industry has huge space for development
Compared with last year, in 2022, electric energy storage ushered in the spring of the industry.
From the perspective of the electric energy storage market, the dual driving factors of the domestic and overseas markets are obvious. Chinese market: With the continuous outbreak of China's shared energy storage construction + wind power distribution and storage demand, domestic investors continue to increase the purchase scale of energy storage batteries and systems, and purchase orders for GWh-level lithium battery energy storage come and go. Overseas markets: The US IRA Act extends the ITC tax rebate subsidy, Japan's photovoltaic FIT is transformed into a FIP policy encouragement, and the enthusiasm for investment in energy storage projects has increased under the European energy crisis.
Judging from the dynamics of major mainstream energy storage lithium battery companies, major companies accelerated overseas market expansion in 2022, and their lithium battery export business has entered a period of rapid growth.
From the point of view of the electric energy storage battery itself, the battery capacity and the number of cycles are obviously competing. 280Ah cells have gradually become the mainstream of power storage, and will quickly enter the post-280Ah cell era, with a capacity of more than 300Ah.
GGII annual statistics show that the shipment of electric energy storage batteries in 2022 is 92GWh, increased 216.2%.
Portable energy storage accelerates into the "blue ocean"
Portable energy storage continue to grow rapidly in 2022.
For a long time, the portable energy storage track has been regarded as a blue ocean track by the industry. GGII also believes that the three major driving forces for portable energy storage are obvious: 1) The charging capacity of mainstream systems increased from below 300Wh to 800-1000Wh in 2022, and the trend of high power is obvious; 2) Export demand continues to be fulfilled. Stimulated by the camping economy of the United States and Australia, the natural gas shortage crisis in Europe, and Japan and South Korea’s disaster relief and backup power demand, portable energy storage became one of the hottest categories of cross-border e-commerce in 2022, and shipments continued the high growth trend in 2021; 3) Since 2022, a large number of Chinese enterprises have poured into the portable energy storag field, and consumer electronics giants have entered the market one after another, stimulating a large amount of capital injection into the industry.
From the point of view of the portable energy storage battery (portable power statio) itself, there is an obvious trend of upgrading to large capacity and long cycle. Among them, the capacity of cylindrical cells is increased to more than 3Ah/ cycle life is increased to more than 800 times. On the whole, portable energy storage cells are still dominated by cylindrical 18650 cells, and cylindrical 21700 and larger cylinders have been applied in small batches in some occasions with more stringent charging requirements.
