What Is the Nominal Voltage? The nominal voltage of the battery refers to the voltage exhibited during normal operation. The nominal voltage of secondary nickel-cadmium nickel-hydrogen batteries is 1.2V. While the nominal voltage of secondary lithium batteries is 3.6V.
What Is the Internal Resistance of Battery? It refers to the resistance experienced by the current flowing through the battery when the battery is working. It is composed of ohmic internal resistance and polarization internal resistance. The large internal resistance of the battery will reduce the battery discharge working voltage and shorten the discharge time. … Read more

What Is the Main Structure of Ni-MH battery? The main components of nickel-metal hydride batteries are: positive electrode sheet (nickel oxide), negative electrode sheet (hydrogen storage alloy), electrolyte (mainly KOH), diaphragm paper, sealing ring, positive electrode cap, battery case, etc.
What Are the Commonly Used Standards for Batteries? Commonly used IEC standards for batteries: The standard for nickel-metal hydride batteries is IEC61951-2: 2003 The standards for lithium batteries are GB/T10077_1998, YD/T998_1999, and GB/T18287_2000. IEC, the International Electrical Commission, is a worldwide standardization organization composed of electrical committees of various countries. Its purpose is to promote … Read more
What Is the Electrochemical Principle of Lithium Ion Batteries? The main component of the positive electrode of the lithium ion battery is LiCoO2, and the negative electrode is mainly C. When charging: Positive electrode reaction: LiCoO2 → Li1-xCoO2 + xLi+ + xe- Negative reaction: C + xLi+ + xe- → CLix Total battery reaction: LiCoO2 … Read more
What Is the Electrochemical Principle of Ni-MH Battery? Ni-MH batteries use Ni oxide as the positive electrode, hydrogen storage metal as the negative electrode, and lye (mainly KOH) as the electrolyte. When the nickel-hydrogen battery is charged: Positive electrode reaction: Ni(OH)2 + OH- → NiOOH + H2O–e- Negative reaction: M+H2O +e-→ MH+ OH- When the … Read more
What Are the Differences Between Primary Batteries and Secondary Batteries? The main difference is that the active material is different. The active material of the secondary battery is reversible, while the active material of the primary battery is not. The self-discharge of the primary battery is much smaller than that of the secondary battery. But … Read more
What Is A Battery? Battery is device for energy conversion and storage, which converts chemical or physical energy into electrical energy through reactions. According to the different energy conversion of battery, battery can be divided into a chemical battery and a physical battery. A chemical battery or chemical power source is a device that converts chemical energy into … Read more
The Safety Valve for 18650 Lithium Battery What is the 18650 lithium battery safety valve? The function of the 18650 safety valve When the pressure inside the lithium battery reaches a set value, then the valve is lifted up and the circuit is disconnected to avoid danger. It is somewhat similar to the principle of … Read more
