Lithium battery applications

With the development of microelectronics technology in the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements on power supply. Lithium batteries have entered a large-scale practical stage.

Nickel–metal hydride battery is divided into high-voltage Nickel–metal hydride battery and low-voltage Nickel–metal hydride battery

Low-voltage nickel-metal hydride batteries have the following characteristics: (1) The battery voltage is 1.2~1.3V, which is equivalent to that of nickel-cadmium batteries; (2) The energy density is high, which is more than 1.5 times that of nickel-cadmium batteries; Good performance; (4) can be sealed, strong ability to withstand overcharge and discharge; (5) no dendrite formation, can prevent short circuit in the battery; (6) safe and reliable, no pollution to the environment, no memory effect, etc.
