Introduction to Lithium Batteries

In terms of energy and power

• High energy density: Compared with traditional batteries, lithium batteries can store more electrical energy in a smaller volume and weight, making electronic products thin, light and portable, such as smart phones and laptops. It also provides longer driving ranges for electric vehicles, such as models like the Tesla Model 3 Long Range Edition.

• High power output: It can release a large amount of electrical energy in a short time, meeting the instantaneous high power demands of equipment. For instance, when power tools are in use, it can quickly provide strong power, and when electric vehicles accelerate, it can rapidly output high power.

Cycle life and self-discharge

• Long cycle life: Generally, it can withstand hundreds to thousands of charge and discharge cycles without significant performance degradation, reducing the trouble and cost of frequent battery replacement. For instance, lithium batteries made of materials like lithium iron phosphate can have a cycle life of over 2,000 times under suitable usage conditions.

• Low self-discharge rate: Less power loss when not in use, and more advantages for long-term storage. For example, a fully charged lithium battery can still retain most of its power after being placed for several months.

In terms of ease of use

• No memory effect: Users can charge at any time as needed without having to completely discharge the battery before recharging as in some traditional batteries, making it flexible and convenient to use.

• Wide operating temperature range: It can operate normally within the temperature range of -20℃ to 60℃. Although its performance may decline at low temperatures, it can adapt to more scenarios compared to other batteries.

In terms of safety and environmental protection

• High safety: It is relatively stable and reliable during normal use. Under conditions such as no overcharging, no overdischarging, and no short circuit, serious safety accidents such as fire and explosion rarely occur. Moreover, some lithium batteries, such as lithium iron phosphate, have even better safety.

• Green and environmentally friendly: It is relatively friendly to the environment during the production, use and disposal processes, and does not contain heavy metal elements such as cadmium, lead and mercury that pollute the environment.

In terms of application

Portable electronic devices: They are the main power sources for mobile phones, tablet computers, laptops, portable audio devices, etc., providing them with long-lasting and stable energy support.

• New energy vehicles: As the core power source, they promote the development of the automotive industry towards electrification and intelligence, reducing the environmental pollution caused by traditional fuel vehicles.

Grid energy storage: It can store excess electrical energy, balance energy supply and demand, improve energy utilization efficiency, and ensure the stable operation of the power grid.

• Industrial applications: It is widely used in industrial equipment and tools such as electric vehicles, unmanned aerial vehicles, wireless sensors, emergency lighting, and UPS systems.
