As the data center market continues to grow, demand for backup data center batteries (UPS) will continue to rise.Lead-acid batteries are still the bulk of backup batteries in data centers, but lithium-ion batteries are expected to replace them in the future due to their long service life, fast charging and discharging speed and small size, according to EnergyTrend.Lithium-ion batteries will account for 12 percent of backup batteries in data centers in 2019 and are expected to grow to 16 percent by 2020.
The overall cost of ownership of lithium batteries is superior to that of lead-acid batteries
Jibang pointed out that lead-acid batteries have a history of 100 years and have been widely used in various energy storage systems.Excluding new energy vehicles, the lead-acid battery market exceeded 380GWh in 2019, with 92% of them starting lighting and ignition (SLI) and 75% of them using backup power (UPS).The other applications are mainly small and medium-sized batteries such as nickel metal hydride batteries or lithium ion batteries due to the limitation of product volume.Although lead-acid battery has the advantages of mature development and low initial purchase cost, it is still difficult to overcome the problems of small discharge range and frequent maintenance.
In contrast, lithium-ion batteries have gradually entered mass production, benefiting from the rapid expansion of new energy vehicles, and their price and technology have been optimized by successive manufacturers.In terms of energy density, charging and discharging speed and maturity of experience, lithium-ion batteries have the opportunity to be introduced into more applications.
From the perspective of total cost of ownership (TCO), lithium ion batteries have a long service life and a high discharge ratio, while lead-acid batteries need to add generators in installation considering their endurance, so their initial cost advantage is often lost due to the prolonged purchase time in cost competition.In addition, the lithium ion battery solution can effectively reduce the size of the backup power system, so it has been gradually adopted by large data centers recently.Jibang expects the proportion of future applications importing backup batteries to increase rapidly as li-ion batteries become more cost-effective.
Data center backup battery to share development
With the development of the server industry, the data storage configuration of data centers will shift from decentralization to sharing, which will also drive the ancillary standby battery function from single and decentralized to sharing.In addition to being the backup power of the data center, the standby battery can maintain the integrity and continuous transmission of data. In the future, when the power grid is overloaded and standby power needs to be started, the emergency standby power system of the large data center can be effectively connected to generate power.Although the energy storage system of the current power grid is still dominated by large-scale centralized battery system, in the future, as the smart power grid becomes more mature, the decentralization and sharing of energy storage is bound to become the future development direction.
