What do you mean by battery?
Batteries are energy conversion and storage devices that convert chemical or physical energy into electrical energy through a reaction. According to the different energy conversion of the battery, the battery can be divided into chemical batteries and physical batteries.
What are the differences between primary and secondary batteries?
The main difference is the active substance, which is reversible in secondary batteries and not in primary batteries. The self-discharge of primary batteries is much smaller than that of secondary batteries, but the internal resistance is much larger than that of secondary batteries, so the load capacity is lower.
What are the main structural components of a NiMH battery?
The main components of nickel-metal hydride batteries are: positive electrode plate (nickel oxide), negative electrode plate (hydrogen storage alloy), electrolyte (mainly KOH), diaphragm paper, sealing ring, positive cap, battery case and so on.
What are the main structural components of a lithium-ion battery?
The main components of lithium-ion batteries are: upper and lower battery cover, positive electrode (active substance is lithium cobalt oxide), diaphragm (a special composite membrane), negative electrode (active substance is carbon), organic electrolyte, battery shell (divided into two kinds of steel shell and aluminum shell) and so on.
What is nominal voltage?
The nominal voltage of the battery refers to the voltage shown during normal operation, the nominal voltage of secondary Ni-Cd-Ni-MH battery is 1.2V; the nominal voltage of secondary lithium battery is 3.6V.
What is open circuit voltage?
Open circuit voltage is the potential difference between the positive and negative terminals of the battery when the battery is not in working condition, i.e., when there is no current flowing in the circuit. Working voltage, also known as terminal voltage, is the potential difference between the positive and negative terminals of the battery in the working state, i.e., when there is current in the circuit.
What are the main aspects of performance commonly referred to as secondary batteries?
It mainly includes voltage, internal resistance, capacity, energy density, internal pressure, self-discharge rate, cycle life, sealing performance, safety performance, storage performance, appearance, etc., and other overcharging, over-discharging and corrosion resistance.
