Summarize the circuit design knowledge of lithium-ion batteries

Summarized the circuit design of lithium ion batteries. Lithium ion batteries have the advantages of small size, large capacity, light weight, no pollution, single voltage, low self-discharge rate, and many battery cycles, but they are more expensive. Due to low capacity, serious self-discharge and environmental pollution, nickel-cadmium batteries are being phased out. Ni-MH batteries are cost-effective and do not pollute the environment, but the single voltage is only 1.2v, and the range of use is limited. Li-ion battery characteristics: 1. Long life. Under normal working conditions, the number of charging and discharging of lithium-ion batteries far exceeds 500 times; 2. Can be used in parallel at will; 3. Higher weight-to-energy ratio and volume-to-energy ratio; 4. No memory effect. Lithium-ion batteries do not have the so-called memory effect of nickel-cadmium batteries, so do not discharge lithium-ion batteries before charging; 5. The self-discharge is small and the storage time is long, which is the most prominent advantage of the battery; 6. The cost is too high. Lithium-ion batteries are more expensive than other rechargeable batteries. 7. High voltage. The voltage of a single lithium-ion battery is 3.6v, which is equal to the series voltage of three nickel-cadmium or nickel-metal hydride rechargeable batteries; 8. The battery is the most advanced green battery because it does not contain heavy metal elements such as cadmium, lead, mercury, and has no impact on the environment. Pollution.
