Which battery is commonly used in photovoltaic power generation
Lead-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.
YA Xinxun (correspondent Du Pengfei) The Eighth Environmental Protection Inspect of Central Environmental Protection Inspect on August 11th, the Xinjiang Uygur Autonomous Region and Xinjiang Production and Construction Corps will carry out environmental protection inspections. At the mobilization meeting, Chen Nation, the party secretary of the autonomous region, requested that all units at all levels should take the initiative to accept inspections, resolutely cooperate with inspections, and fully support the inspectors, in accordance with the highly responsible attitude, real report work, objectively deliberately provide Seeing truth from facts reflecting the problem, ensuring that the Central Inspector Team successfully carried out various work. In the past few days, Altai region quickly acts quickly according to the requirements of the Central Environmental Protection Inspector, does not wait, not delayed, carefully check the problem, and seize the development of rectification measures, promoting the ecological environmental protection task with a high degree of responsibility. .
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.
