Primary battery: active substance consumed to a certain degree, can not be used. For example: Zn-MnO2, Zn-HgO, Zn-AgO, lithium batteries, etc.
♦ Features ♥ Applications
Zn-Mn battery
♦ Ordinary, low price, available in various sizes
♥ Radio, electronic equipment, toys, quartz clocks, etc.
Alkaline Zn-Mn battery
♦Can discharge at a large current, good low temperature performance
♥Walkman, electric instrument, toy, razor, etc. need to discharge with a large current
Li-SO2 battery
♦Cylindrical-based, suitable for large current discharge, excellent low temperature performance, long life, safety performance is worse than zinc-manganese battery, higher price
♥Night vision viewer, missile ignition, aircraft first aid instructions, cameras, etc.
Li-MnO2 battery
♦ Larger specific energy, stable discharge voltage; better storage life; less self-discharge; relatively low price, poor safety of large-capacity high-power battery
♥Electronic watches, calculators, hearing aids, tape recorders, etc., are widely used
Li/SOCl2 battery
♦Larger specific energy, stable discharge voltage; better storage life; less self-discharge; excellent temperature characteristics, poor safety of large-capacity high-power batteries ♥Night vision viewer, missile ignition, aircraft first aid instructions, cameras, etc.
Zn/Ag2O battery
♦ Button-type, high specific energy, stable discharge voltage, long life; high cost
♥Small current continuous discharge ultra-small measuring instruments such as electronic watches, calculators, hearing aids, cameras, etc.
Zinc air battery
♦Wide capacity range, high specific energy, stable discharge voltage, long life and low price. ♥Electronic watches, hearing aids, navigation lights, railway signals, communication-testers, field surgery lighting, electric toys, electronic instruments.
