The advantages of lithium batteries are: high energy ratio, long life, high power endurance, light weight, green and environmentally friendly.
In order to adapt to the development of society, the advent of lithium battery products has greatly reduced the frequency of replacement of electric vehicle batteries, extended their service life, and saved energy and costs at the national level. However, because it is a new product, it has received limited attention and more and more people are not particularly aware of it. The advantages of lithium batteries include the following aspects:
1. light weight, small size, power of lithium battery electric bicycles Performance is similar to lead-acid batteries (single electric bicycles). It takes 6-8 hours to charge and can travel 30-45 kilometers depending on battery capacity. only represents approx.iron 1/5 of the lead acid battery. The biggest advantage of lithium battery electric bikes is their long lifespan. Warning: People who say lithium batteries are expensive are only looking at their appearance. In fact, if you carefully calculate their cost, they are almost the same as lead acid batteries. Nowadays, regular lithium batteries have a 2-year warranty. lead acid batteries have a one year warranty.
2. Lithium batteries have non-activation characteristics. When using lithium batteries, it should be noted that the battery will enter a dormant state after being left for a period of time. lower than the normal value and the usage time is also shortened. But lithium batteries are very easy to activate. It only takes 3-5 normal charge and discharge cycles to activate the battery and restore its normal capacity. Due to the characteristicsics of the lithium battery itself, it has almost no memory effect. Therefore, users do not need any special methods or equipment during the activation process of new lithium batteries.
3. Green and environmentally friendly, regardless of production, use or disposal, it does not contain or produce toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium .
1. At the same time, lithium batteries have the following disadvantages:
1) Primary lithium batteries have poor safety and may explode.
2) Lithium-ion batteries based on lithium cobalt oxide cannot be discharged at high currents and are unsafe.
3) Lithium batteries need protection circuits to prevent the battery from being overcharged or discharged.
2. The lithium-ion polymer batteryst the most commonly used lithium-ion battery, very common in various electronic devices. As an improvement over ordinary lithium-ion batteries, this lithium polymer uses a colloidal or solid polymer to replace the liquid organic solvent in ordinary lithium-ion batteries. It is safer, does not explode, and can be shaped into different battery cell shapes. . Therefore, this type of lithium polymer battery is used in various portable electronic devices and pure electric vehicles.
