Batteries - A detailed comparison of two types of VRLA batteries

There are two types of VRLA batteries: one is VRLA battery using ultra-fine glass fiber membrane (AGM); the other is VRLA battery using colloidal electrolyte (GFL) (abbreviated as GFL-VRLA battery). They all use the principle of cathode absorption to seal the lead-acid battery. Therefore, there must be about 10% of the diaphragm gap in the […]

Colloidal lead-acid battery - the structure and advantages and disadvantages you must understand

Colloidal lead-acid battery Lead-acid batteries have been the most widely used chemical power sources in military and civilian fields since their inception to the present. Since it uses sulfuric acid electrolyte, acid will flow out during transportation, and acid mist will be precipitated during charging, which will cause damage to the environment and equipment. People […]

What are the discharge characteristics of VRLA battery?

Discharge characteristics VRLA batteries are subject to capacity test before leaving the factory. According to YD / t799-1996 standard, the steps of capacity test are as follows: (1) First, fully charge the tested VRLA battery. (2) Leave the VRLA battery under test for 1 ~ 24h to make the surface temperature of the battery reach […]

What is the working principle of the lead-acid battery of the LED street light system?

In the mid-19th century, the advent of lead-acid batteries solved the problem of random power consumption of some electrical equipment. But after more than 100 years of development, its working principle has basically not changed. The chemical equation of its normal charge and discharge is:PbO2+2H2SO4+Pb↔2PbSO4+2H2O The above normal charge and discharge chemical equations are idealized […]

What are the technical indicators of the battery?

1) The capacity of the batteryThe amount of electricity that the battery can give under certain discharge conditions is called the capacity of the battery, which is commonly expressed as C. However, when a battery is used as a power source, since its terminal voltage is a variable value, it is more accurate to use […]

What is the classification of batteries for new energy LED street lights?

For the types of batteries, as far as the mainstream products on the market are concerned, there are four types of batteries: lead-acid batteries, nickel-cadmium (NiCd) batteries, nickel metal hydride (NiMH) batteries and lithium ion (Liion) batteries. The battery can be used repeatedly, which is in line with the principle of economy and practicality. This […]

What are amorphous silicon solar cells for photovoltaic systems?

Two key issues in developing solar cells are: improving conversion efficiency and reducing cost. Due to the low cost and easy mass production of amorphous silicon thin film solar cells, they have been widely paid attention to and developed rapidly. As early as the early 1970s, Carlson et al. started the research and development of […]

What is a polycrystalline silicon solar cell?

Although monocrystalline silicon solar cells have their advantages, their high price hinders the development of monocrystalline silicon solar cells in the low-cost market. The polycrystalline silicon solar cell is the first to reduce costs, followed by efficiency. Although polycrystalline silicon solar cells and monocrystalline silicon solar cells have different crystal structures, the photovoltaic principle is […]

What is a monocrystalline silicon solar cell?

Monocrystalline silicon solar cells are cut from cylindrical ingots, not complete squares, resulting in some waste of refined silicon materials. Therefore, most of the monocrystalline silicon will have gaps in the four corners, which are easy to distinguish in appearance. The structure and production process of monocrystalline silicon solar cells have been finalized, and the […]
