Problems solved by technology

[0002] Among the currently used walkie-talkie batteries, there are mainly nickel-metal hydride batteries and nickel-cadmium batteries. The specific energy of these two batteries is relatively small, the production process is relatively complicated, and the talk and standby time used on walkie-talkies is relatively short.
At the same time, these two batteries are bulky, heavy, inconvenient to carry, and have a memory effect
