How much do you know about explosion-proof walkie-talkie lithium batteries?

Explosion-proof walkie-talkie lithium batteries have a higher power-to-weight ratio: under the same size or weight, lithium-ion batteries can store more power than nickel-cadmium or nickel-metal hydride batteries.

Low self-discharge rate of explosion-proof walkie-talkie lithium batteries: Li-ion batteries are suitable for use in standby or intermittent use equipment. Depending on the temperature at which the electrical energy is stored, nickel-metal hydride and nickel-cadmium batteries lose 1-5% of their power each day.

Discharge mechanism of lithium-ion rechargeable batteries: Although it is called a lithium battery, the battery does not contain lithium metal. Its working principle uses the implantation and extraction of lithium ions on the electrode. The negative electrode is made of a graphite mixture, and the positive electrode is made of a lithium cobalt oxide material.


Explosion-proof walkie-talkie lithium battery has a higher nominal battery voltage: The nominal voltage of a lithium battery is usually 3.7V, allowing a higher standard voltage to be easily achieved. Traditional nickel-cadmium batteries or Ni-MH batteries are only 1.2V. When designing a 12V or higher battery pack, more batteries are required and the internal resistance is higher.

Explosion-proof walkie-talkie lithium batteries have a longer service life: lithium-ion batteries can be recharged about 1,000-1200 times, while nickel-metal hydride batteries of similar capacity are only 500-1000 times.

Small "memory" effect: If the Ni-Cd battery is repeatedly charged half-charged and then discharged, chemical changes will occur inside the battery and the battery will no longer be fully charged; the same is true for Ni-MH batteries, but the performance is slightly better, Lithium-ion batteries are largely free of such phenomena.

Higher peak discharge current: Although not as good as nickel-cadmium batteries, TV lithium batteries can also provide high peak currents; continuous improvement in the structure of lithium electronics has fully blossomed in the walkie-talkie industry, and nickel-cadmium batteries can only be selected before lithium Or nickel-metal hydride batteries, which makes many walkie-talkie users helpless choice.
