Which battery is commonly used in photovoltaic power generationLead-acid, maintenance, battery
* Big characteristics is "maintenance", and lead-acid batteries than its electrolyte consumption is very small, basically no need to supplement distilled water in service life. It also has the characteristics of high temperature resistance, high temperature, small size and small discharge. Relative, its price is also more expensive than lead-acid batteries. As for the service life, the recommended replacement cycle of the battery is maintained in normal conditions is about 3 years, which is comparable to the lead-acid battery.
Ordinary lead-acid battery
The battery is invented by French Prante in 1859, has had a history of more than 100 years. The battery is mainly composed of a tubular positive electrode plate, a negative electrode plate, an electrolyte, a partition, a battery tank, a battery cover, a pole column, a liquid cover, and the like. The main advantage is that the voltage is stable, the price is cheap; the disadvantage is that the energy is low (i.e., electrical energy stored per kilogram battery), the service life is short of usual maintenance. Old-style ordinary battery is in a general life of about 2 years, and the height of the electrolyte is required regularly and add distilled water. However, with the development of technology, the life of lead-acid batteries has become longer and the maintenance is also simpler.

Time, deputy director of the Pengzhou Environmental Protection Bureau, the captain of the Environmental Monitoring Law Enforcement Brigade Zhou We Weiwei is subject to the party's warning. When he was a Pengzhou Environmental Protection Bureau, Song Tianwei was talked from the command. Problem Problem of Lichuan Wood and Sanmu Chemical Waste in Hejiang, China, Sichuan Province. On August 10, 2017, the masses raised to the central fifth Environmental Protection Inspector, Lichuan Wood and Sanyang Chemical, Lichuan Wood and Sanyang Chemical, who had long-term late night to the Yangtze River. After investigation, the mass reporting problem is true. Since 2016, the masses have repeatedly to the Hejiang Lingang Industrial Park Management Committee, the Hejiang County Environmental Protection Bureau, China, China, the Environmental Protection Bureau, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, Environmental Protection Bureau, has been reported to the environmental issues of Lifawa Wood and Sanmu Chemical Pollution Environment.
Colloidal battery
The colloid lead-acid battery is an improvement in the ordinary lead-acid battery of the liquid electrolyte, and the electrolytic solution is exchanged with a colloidal electrolyte, which is improved in terms of safety, storage capacity, discharge performance, and service life. There is no free-free liquid in the inner, in the same volume, the electrolyte capacity is large, the heat capacity is large, and the heat dissipation ability is strong. It can avoid the general battery to generate thermal out-of control; the electrolyte concentration is low, the corrosion of the plate is weak; concentration is uniform, there is no electrolysis Liquide layers.
