lithium-ion battery - Names and Identifiers
lithium-ion battery - Introduction
Lithium-ion batteries are a common type of rechargeable batteries. Its main feature is the use of lithium ions for charge transfer between positive and negative electrodes to store and release electrical energy. The following is an introduction to the nature, use, preparation and safety information of lithium-ion batteries:
Nature:
1. High energy density: Lithium-ion batteries have high energy density, which means they can store more electricity, making them widely used in small devices.
2. Long cycle life: Lithium-ion batteries usually have a long cycle life and can be reused hundreds of times.
3. No memory effect: Lithium-ion batteries have no memory effect and do not need to be fully discharged before charging.
4. Low self-discharge rate: Compared with other types of batteries, lithium-ion batteries have a lower self-discharge rate and are not easy to lose their charge.
Use:
1. Electronic devices: Lithium-ion batteries are widely used in mobile phones, laptops, tablets and other portable electronic devices to provide a long-lasting power supply.
2. Electric vehicles: With the rise of electric vehicles, lithium-ion batteries have also become the preferred power source for electric vehicles.
3. Solar energy storage: Lithium-ion batteries are used in energy storage devices for solar panels and wind power generation systems to provide electricity in the absence of light or wind.
Preparation Method:
The production of lithium-ion batteries involves a variety of materials, such as lithium-ion conductors, cathode materials and anode materials. The specific steps of the preparation method include stirring, forming, assembling and sealing.
Safety Information:
1. Avoid overcharging and overdischarging, so as not to damage battery performance or cause heat generation.
2. Avoid the use of high temperature environment, so as not to cause thermal runaway and fire.
3. Avoid physical damage, such as extrusion, impact and puncture, to prevent short circuit and leakage of the battery.
4. During long-term storage, the battery should be kept at a moderate level, not fully charged or discharged.
5. When there is no suitable battery recycling and disposal facilities, do not discard lithium-ion batteries at will.
