As a  Power Tool Batteries Supplier , let's share with you the advantages of Ni-Cd Battery. Ni-Cd Battery The positive active material is mainly made of nickel, and the negative active material is mainly an alkaline storage battery made of cadmium. The positive electrode is nickel hydroxide, the negative electrode is cadmium, and the electrolyte is a potassium hydroxide solution. Its advantages are light weight, shock resistance and long life, and it is often used in small electronic devices. Ni-Cd Battery The positive electrode material of  Ni-Cd Battery  is a mixture of nickel hydroxide and graphite powder, and the negative electrode material is sponge mesh cadmium powder and cadmium oxide powder, and the electrolyte is usually sodium hydroxide or potassium hydroxide solution. When the ambient temperature is high, a sodium hydroxide solution having a density of 1.17 to 1.19 (at 15 ° C) is used. When the ambient temperature is low, a potassium hydroxide solution having a

Since its inception in 1990, Lithium Battery For solar has been rapidly developed for its superior performance and is widely used in society. Lithium-ion batteries quickly occupy many fields in the incomparable advantages of other batteries, such as mobile phones, laptops, small cameras, and so on. As an  Emergency Lighting Products Manufacturer , let's share with you. The basic principle recognized by lithium batteries at present is the so-called "rocking chair theory". The discharge and discharge of a lithium battery is not a transfer of electrons in a conventional manner, but an energy change occurs by the passage of lithium ions in the crystal of the layered substance. In the case of normal rushing and discharging, the ingress and egress of lithium ions generally only causes the change of the layer spacing without causing the destruction of the crystal structure. Therefore,  Lithium Battery For solar  is an ideal reversible battery in terms of impulse discharge. Du

What is the difference between Ni-MH Battery and lithium battery? As a  Ni-Cd Battery Pack Supplier , let's explain it to everyone. First, the weight aspect In terms of the voltage of each unit cell, nickel-metal hydride and nickel-cadmium are both 1.2V, while lithium batteries are indeed 3.6V, and the voltage of lithium batteries is three times that of the other two. And the weight of the same type of battery lithium battery is almost equal to the nickel-cadmium battery, while the Ni-MH Battery is relatively heavy. It can be seen that the weight of each battery itself is different, but the lithium battery is reduced by 1/3 of the single battery when outputting the same voltage due to the high voltage of 3.6V, so that the weight and volume of the battery after molding are reduced.  Second, the memory effect Ni-MH Battery  has the same memory effect as nickel-cadmium batteries. Therefore, regular discharge management is also required. This kind of periodic discharge managem

As an  Emergency Lighting Products Supplier , let's talk about the difference between Ni-Cd Battery and Ni-MH Battery. 1. Different battery materials: (1) The active material on the Ni-Cd Battery positive electrode plate is composed of nickel oxide powder and graphite powder, and its main function is to enhance conductivity. The active material on the negative electrode plate is composed of cadmium oxide powder and iron oxide powder. The function of the iron oxide powder is to make the cadmium oxide powder have high diffusibility, prevent agglomeration, and increase the capacity of the electrode plate. (2)  Ni-MH Battery  positive active material is Ni(OH)2 (called NiO electrode), negative electrode active material is metal hydride, also called hydrogen storage alloy (electrode called hydrogen storage electrode), electrolyte is 6mol/L hydrogen Potassium oxide solution. 2. Different classifications: Ni-MH Battery is divided into high-voltage nickel-metal hydride batteries

Generally, the newly purchased electric vehicle lithium battery is new, the capacity is also large, the charging time will be longer, and the lamp will be kept for more than 10 hours. It will be faster and faster in the future, and will be reduced to 6 hours in about 2 months. After that, it will last for about half a year, and the battery capacity will continue to decay. It can be filled in 3-4 hours after one year. Of course, the battery should be replaced or need maintenance. E-bike Battery Exporter  recommends: charging time for the first charge, because the battery car battery has not been used before charging, has not experienced charging and discharging, to ensure the normal operation of the battery. Under normal circumstances, the charging time is about 5-6 hours, so that the battery can be fully charged, and the subsequent application can be charged a little longer. After the first charge, although it is not the first time to charge, but the second time is considered a ne
