502030 battery.With the continuous development of lithium battery technology, the history of UPS may be rewritten

　　The IDC market is currently one of the areas with the strongest demand for UPS. According to statistics from relevant institutions, the compound growth rate of the domestic IDC market in the past eight years has reached 42.3%.

　　Among them, the IDC market was in a period of rapid growth from 2009 to 2011, with the annual growth rate maintaining above 40%.

　　Affected by the macroeconomic downturn in 2012 and 2013, the overall market growth rate dropped to less than 25%; since then, on the one hand, the government has strengthened policy guidance and gradually opened up IDC license applications. On the other hand, big data, cloud computing and other industries have emerged, and data The market demand for the center is increasing.

　　In 2014, the IDC market growth rate once again exceeded 40%. In 2015, the market growth rate was 39.3%. In 2016, the market growth rate also reached 38.1%. It is predicted that the market growth rate will continue to be around 40% this year and next. Next year, the IDC market size is expected to be close to 140 billion yuan, which will significantly boost the demand for UPS.

　　With the rapid development of the UPS market, the demand for UPS batteries is also increasing. As an important part of the UPS system, batteries have many specifications and types, and corresponding battery types must be selected for different application fields. Commonly used battery types for UPS are as follows:

　　1. Lead acid battery

　　The most commonly used lead-acid battery at present is the valve-regulated lead-acid maintenance-free battery. The electrolyte is mainly composed of lead and sulfuric acid. It is characterized by no need to add water or acid when used. It has good sealing performance and is relatively small in size. It is cost-effective as a UPS battery. .

　　2. Gel battery

　　As another commonly used type of UPS battery, gel batteries are called gel batteries because their electrolyte is in a colloidal state. The designed service life of gel batteries is longer than that of ordinary lead batteries, and their performance is more stable, so the price is relatively high.

　　3.Lithium battery

　　Lithium batteries are the first choice for green and environmental protection. Lithium batteries do not contain heavy metals such as lead, nickel, and chromium. Compared with ordinary lead-acid batteries, lithium batteries have the characteristics of light weight, high energy storage and low self-discharge, but the price is also relatively low. high.

　　The continuous breakthroughs and updates in lithium battery technology research may rewrite the history of UPS.

　　At present, many large companies at home and abroad have begun to deploy the UPS lithium battery market. Although lithium batteries are currently 2-3 times more expensive than lead-acid batteries, with the continuous development of lithium battery technology, its cost will also drop significantly. At present, The price difference between the two batteries is shrinking at a rate of 20% per year. It is expected that within two to three years, the price of lithium batteries will gradually converge with the price of lead-acid batteries.

　　The advantage of lithium batteries is that they are less sensitive to temperature fluctuations and can accept temperature changes, which allows customers to reduce their cooling capacity, reduce energy consumption, and reduce floor space. In the domestic market, UPS applications such as Shanghai Metro have begun to partially use lithium batteries to replace lead batteries. It is not difficult to see that lithium batteries are gradually changing the history of lead-acid batteries dominating UPS.
