18650 rechargeable battery lithium 3.7v 3500mah

　　Which is better, 18650 rechargeable battery lithium 3.7v 3500mah or lead-acid battery?

　　As the world's most advanced secondary battery (rechargeable battery), 18650 rechargeable battery lithium 3.7v 3500mah has become a high-capacity battery due to its small size, light weight, high specific energy, long life, no memory, environmental protection, and reliability. Ideal switching power supply for rechargeable batteries - instrument panel. Under the same operating voltage and volume, compared with lead-acid batteries, the volume decreases and the net weight is reduced by a quarter. The service life of rechargeable batteries is three times that of lead-acid batteries. The volume and weight of lithium batteries are only half that of nickel-metal hydride or nickel-cadmium batteries, and their service life is twice that of nickel-metal hydride rechargeable batteries.

　　Lead rechargeable batteries are one of the more widely used rechargeable batteries. Use a laminated glass or plastic pot, add hydrochloric acid, and then plug in two graphite plates. One positive terminal is connected to the charging head, and one negative terminal is connected to the charging head. After charging the battery for more than ten hours, the rechargeable battery is produced.

　　Lithium battery:

　　Rechargeable batteries using lithium as the negative stage are a new type of high-energy battery developed after the 1960s. Lithium battery electrolyte:

　　1. High temperature molten salt lithium battery;

　　2. Organic electrolyte lithium battery;

　　3. Inorganic non-aqueous electrolyte lithium battery;

　　4. Solid electrolyte lithium battery;

　　5. 18650 rechargeable battery lithium 3.7v 3500mah

　　The advantages of lithium-ion batteries are high operating voltage, high energy density, long storage life (up to ten years), high and low temperature test characteristics, and can be used in the range of -40°C to 150°C. The development trend of power engineering lithium batteries and new battery cathode materials, especially the development trend of lithium iron phosphate battery raw materials, has greatly promoted the development trend of lithium batteries.
