Introduction to the characteristics and classification of lithium-ion batteries

The characteristics of lithium-ion batteries 1. It has a higher weight-to-energy ratio and volume-to-energy ratio; 2. The voltage is high, and the voltage of a single-cell lithium-ion battery is 3.6V, which is equal to the series voltage of three nickel-cadmium or nickel-hydrogen rechargeable batteries; 3. The self-discharge is small and can be stored for a long time, which is the most prominent advantage of the battery; 4. No memory effect. Lithium-ion batteries do not have the so-called memory effect of nickel-cadmium batteries, so lithium-ion batteries do not need to be discharged before charging; 5. Long life. Under normal working conditions, the number of charge/discharge cycles of lithium-ion batteries is far greater than 500; 6. It can be quickly charged. Lithium-ion batteries can usually be charged with 0.5 to 1 times the capacity current, which shortens the charging time to 1 to 2 hours; 7. They can be used in parallel at will; 8. Because the battery does not contain heavy metal elements such as cadmium, lead, mercury, etc., it is environmentally friendly It is pollution-free and is the most advanced green battery in the contemporary era; 9. High cost. Compared with other rechargeable batteries, lithium-ion batteries are more expensive. In addition, there are many types of lithium-ion batteries, let’s take a look at them together: 1. According to the appearance of lithium-ion batteries: square lithium-ion batteries (such as commonly used mobile phone battery cells) and cylindrical lithium-ion batteries (such as 18650) ); 2. According to the lithium-ion battery outsourcing materials: aluminum shell lithium-ion batteries, steel shell lithium-ion batteries, soft pack batteries; 3. According to the positive and negative electrode materials (additives) of lithium-ion batteries: lithium-ion battery (LiCoO2) batteries Or lithium manganese oxide (LiMn2O4), iron phosphate lithium ion battery, disposable manganese dioxide lithium ion battery; another classification method: lithium ion LIB, polymer PLB4. Different performance and use aspects: disposable lithium ion battery- --Lithium manganese battery--Button 3V battery high capacity (high platform) lithium ion battery--Used in mobile phone digital products with high rate lithium ion battery;---Used in electric vehicles and power tools and high temperature aircraft models Lithium ion battery; ---Miner's lamp, indoor lighting, machine built-in backup power; low temperature lithium ion battery; ---outdoor environment, north (winter) south pole; 5. Lithium ion batteries are also divided into two categories: non-rechargeable and rechargeable There are two types of charging.
