Which type of lithium battery is better for solar street lights？
Solar street lights generally use lithium iron phosphate batteries.
1、 Types of lithium batteries required for solar street lights
Solar street lights are lighting devices that use solar energy as their energy source. During clear days, solar panels convert solar energy into electrical energy and store it in batteries. At night, the solar panels stop working and the batteries provide power to the streetlights. Therefore, solar street lights require the use of a battery that can store electrical energy, and this battery needs to have characteristics such as high efficiency, long lifespan, easy maintenance, and environmental friendliness.
The commonly used types of lithium batteries in the current market include lithium manganese oxide, lithium cobalt oxide, ternary lithium, and lithium iron phosphate. These four types of lithium batteries have their own advantages and disadvantages. Let's analyze them in detail below.
1. Lithium manganese oxide battery: Low cost, but small capacity and short lifespan, not suitable for solar street lights.
2. Lithium cobalt oxide battery: Large capacity, but expensive and environmentally friendly, may pose safety hazards during use, and is not suitable for use in solar street lights.
3. Ternary lithium battery: It has the advantages of high energy density and long lifespan, but also has the problem of high cost and is not suitable for use in solar street lights.
4. Lithium iron phosphate battery: Large capacity, moderate cost, good safety, environmental friendliness, and relatively long lifespan. Therefore, lithium iron phosphate batteries are currently the most commonly used type of battery in solar street lights.
2、 Advantages of
Solar Street Light Battery
Lithium iron phosphate batteries are more environmentally friendly and safe than other lithium batteries, without heavy metal pollutants and harmful substances. They also have advantages such as high efficiency, high energy density, long charging time, and long lifespan. Lithium iron phosphate batteries do not generate heat or cause fires during operation, making them a more reliable battery.
