Lithium-ion batteries are a common rechargeable battery technology with the following key features:

1. High energy density: Lithium-ion batteries have relatively high energy density , more energy can be stored in a battery of the same volume or mass. This makes lithium-ion batteries the battery technology of choice for many mobile devices (such as smartphones, laptops) and electric vehicles.

2. Long cycle life: Lithium-ion batteries have a long cycle life and can be charged and discharged hundreds to thousands of times without significant loss of capacity. This makes lithium-ion batteries a reliable energy storage solution for applications that require frequent charging and discharging.

3. Low self-discharge rate: Lithium-ion batteries have a low self-discharge rate, that is, they lose less charge on their own when stored for a long time or not in use. This allows lithium-ion batteries to have longer retention times and perform better in storage and backup power applications.

4. No memory effect: Lithium-ion batteries have no "memory effect", that is, they do not need to be completely discharged and recharged. They can be partially discharged and charged without affecting their rated capacity. This makes devices using lithium-ion batteries more flexible and convenient.

5. Fast charging and discharging capabilities: Lithium-ion batteries have high charging and discharging efficiency and can quickly store and release electrical energy. This is important for applications that require fast charging or rapid release of energy over a short period of time.

6. Environmental protection and safety: Lithium-ion batteries have advantages in environmental protection and safety compared to other chemical battery technologies. They do not contain heavy metal contaminants (such as cadmium, lead) and can be designed and manufactured with appropriate safety measures to reduce the risk of fire and explosion.

It should be noted that lithium-ion batteries also have some limitations, such as limited charging speed, temperature sensitivity, high cost, etc. When using them, you still need to follow the relevant usage and charging requirements to ensure Ensure safety and optimal performance.
