In physics, the process of emission and transmission of energy in the form of electromagnetic waves or photons is called electromagnetic radiation. Light is a part of electromagnetic radiation, which is electromagnetic radiation with wavelengths between the transition region to X-rays (λ≈1 nm) and the transition region to the radio band (λ≈1 mm). Not all […]
Valve regulated lead acid battery (VRLA battery for short) was born in the 1970s. Although this battery is also a lead-acid battery, it has many advantages compared with the original lead-acid battery, and is popular with users, especially for users who need to install battery supporting equipment together (or a workshop), such as UPS, telecommunications […]
After understanding the charging and discharging characteristics of battery, how to control the charging and discharging process is the key to the application of battery in photovoltaic power generation system. In 1967, American scientist J.A. MAS made a lot of experimental research on the gas evolution problem in the charging process of lead-acid batteries, and […]
1. The development of lead-acid batteriesThe lead-acid battery was invented by Plante in 1859 and has a history of more than 100 years. Since its invention, lead-acid batteries have always had an absolute advantage in chemical power sources. This is because of its low price, easy availability of raw materials, sufficient reliability in use, suitable […]
In photovoltaic systems, especially stand-alone photovoltaic systems, it is very important to choose a suitable battery. When choosing a battery, power, weight and quality are mainly considered, so the battery is required to be small in size, high in energy density, light in weight, durable and cost-effective. At present, the types of batteries used in […]
Supercapacitors are also called electrochemical capacitors. Its performance is between ordinary capacitors and batteries. It has excellent pulse charge and discharge performance and high-power energy storage performance. Because of its large stored energy, light weight, and multiple charge and discharge A new type of energy storage device. At present, there are many kinds of super […]
A fuel cell is an energy conversion device that directly converts the chemical energy of the supplied fuel into electrical energy through an electrode reaction. It is a power generation device that can continuously obtain electricity by continuously supplying fuel. The biggest feature of this device is that since the reaction process does not involve […]
Lithium batteries are batteries that use lithium metal as the anode. Because lithium metal has lower mass density, higher specific power and higher electrode potential, lithium batteries have higher energy density. Lithium batteries are divided into primary lithium batteries and secondary lithium batteries. The primary lithium battery uses lithium metal as the anode and MnO2 […]
KOH and NaOH aqueous solutions are alkaline, and batteries using them as electrolytes are called alkaline batteries, including iron-nickel, nickel-cadmium, nickel-hydrogen, nickel-hydride, and zinc-silver batteries. At present, nickel-cadmium batteries are commonly used in alkaline batteries. The basic structure is shown in Figure 1. It is mainly composed of nickel hydroxide positive plate, cadmium negative plate […]
The acid battery refers to the battery whose electrolyte is an acidic aqueous solution. At present, the lead-acid battery is the most common application. A typical lead-acid battery consists of positive and negative plates, electrolyte and electrolytic cell, and its basic structure is shown in Figure 1. The active material of the positive plate of […]
