What Kinds Of Batteries Are Used In Solar Power Generation

DS New Energy | Updated: Aug 02, 2018

       1. Lead-acid Maintenance-free battery The biggest feature is "maintenance-free", and lead-acid batteries than its electrolyte consumption is very small, in the service life of the basic need not to replenish distilled water. It also has the characteristics of shock resistance, high temperature resistance, small volume and low self-discharge. In contrast, it will cost more than a lead-acid battery.

  As for the service life, under normal circumstances, maintenance-free battery recommended replacement period of about 3 years, and lead-acid battery equivalent.


  2. Common lead acid battery The battery was invented by the Frenchman Plantation (Plante) in 1859 and has a history of more than more than 100 years. The battery is mainly composed of tubular positive plate, negative plate, electrolyte, clapboard, battery tank, battery cover, pole column, injection liquid cover, etc. The main advantage is voltage stability, low price, disadvantage is lower than can (that is, the battery storage per kilogram of electrical energy), short service life and frequent daily maintenance. Old-style ordinary battery life in general 2 years or so, but also need to regularly check the height of the electrolyte and add distilled water.

  However, with the development of technology, lead-acid battery life becomes longer and maintenance is simpler.


  3. Colloid Battery The colloidal lead-acid battery is an improvement of the common lead-acid battery for liquid electrolyte, and the electrolyte is substituted by the colloid electrolyte, which is better than the ordinary battery in terms of safety, storage, discharge performance and service life.

        There is no free liquid inside, in the same volume of electrolyte capacity, large heat capacity, heat dissipation ability, can avoid the general battery easily produce heat out of control phenomenon, low electrolyte concentration, the corrosion of the plate is weak, uniform concentration, there is no electrolyte stratification phenomenon.


        4. Silicone Salt Storage Battery Silicone Salt Storage battery using "liquid silicone salt nano-electrolyte" and "multiple high tin lead-calcium alloy pole sheet" and other special materials carefully produced, superior performance, different. The development of silicone salt sealed storage battery successfully solved a series of shortcomings and problems such as acid corrosion, thermal failure, acid mist pollution, low energy density and power density and short service life of traditional lead-acid batteries in the process of production, use and waste.

  Kurt Battery is silicone salt battery professional production company.


  5. Alkaline Ni-CD battery Ni-CD Battery (nickel-cadmiumbattery) positive active substances are mainly made of nickel, and negative active substances are mainly made of cadmium as an alkaline battery. is extremely nickel hydroxide, negative extremely cadmium, electrolyte is the potassium hydroxide solution. Its advantages are light, seismic, long life, often used in small electronic equipment. Ni-CD battery can quickly charge, cycle life is longer, is lead-acid battery twice times more, can reach 2000 times, but the price of lead-acid battery 4~5 times. Its initial acquisition cost is high, but because of its advantages in energy color and service life, its long-term actual use cost is not high.


But the use of recycling needs to do a good job, otherwise heavy metal cadmium will pollute the environment. In the selection of batteries, it is necessary to understand the differences between the various kinds of batteries in the process and use, first of all to fully understand the user's own needs for the product. For example, reserve power system capacity requirements, the frequency of use, the use of the environment, the main use, service life, reliability requirements, instantaneous discharge rate, rectifier specifications and other battery-related performance requirements. The second is to understand the electrical properties of the battery, including product design parameters (battery model, appearance size, rated capacity, rated voltage, weight, weight ratio energy, volume ratio energy, design life, positive and negative plate number, positive and negative plate thickness ratio, electrolyte density, plate type, grid material, etc., product electrical performance parameters, The actual life of the products, installation and use of the environment, different models of performance and prices, different types of product warranty.
