Which of the lead -acid batteries and lithium batteries is better?solar battery storage system wholesale

　　1. Price comparison

　　Price cost is the most concerned factor for many manufacturers. Lithium batteries are high, and lithium batteries are three times more expensive than lead -acid batteries.

　　Many manufacturers ultimately choose a large part of the lead -acid batteries because of the price. However, combined with the life analysis of usage, the same cost is still longer.

　　2. Safety performance comparison

　　As a commonly used item, safety must be the most important factor. After strict security testing, lithium batteries will not explode even in severe collisions. Lithium iron phosphate is high and stable, and the electrolyte oxidation capacity is low, so safety is high. The lead -acid battery will explode under a strong collision, which pose a threat to the safety of consumers.

　　3. Green and environmental protection comparison

　　Environmental protection has become a theme of today's era, and environmentally -friendly batteries are more vulnerable to the public. The lithium battery material does not have any toxic and harmful substances. It is considered a green and environmentally friendly battery by the world. The battery has no pollution in production and use. It complies with European ROHS regulations and is green environmentally friendly battery. There are a large number of lead in the lead -acid battery. If it is not handled properly after abandonment, it will pollute the environment.

　　4. Comparison of temperature tolerance

　　The working temperature of the common lithium battery is -20-60 degrees Celsius. However, the performance of lithium battery after 0 ° C will decrease, and the discharge capacity will be reduced accordingly. Therefore, the working temperature of the fully lithium battery performance is 0 ~ 40 ° C. The working temperature of the battery generally requires that the discharge capacity decreases between 20 ° C and 25 ° C. When it is lower than 15 ° C.

　　5. Comparison of cycle life

　　The cycle life determines the battery's usage cycle. Everyone likes to use a battery with a long period of use. The number of lithium batteries is generally around 2000-3000 times, while the number of cycles of batteries is about 300-500 times, and the cycle life of lithium batteries is about five or six times that of the battery.

　　6. Weight energy density

　　The energy density of lithium batteries is generally 200 ~ 260Wh/g, and lithium batteries are 3 to 5 times that of lead acid, which means that under the same capacity, lead -acid batteries are 3 ~ 5 times that of lithium batteries.

　　7. Different charge and discharge

　　The lithium battery has no memory effect. The battery can be charged and discharged at any time, the battery is low -discharge, and the battery can be stored for a long time; the power is strong, it can be charged quickly, it can be over 80%in 20 minutes, and the electricity can be finished in 15 minutes. The battery has a memory effect and cannot be charged at any time at any time. If there is serious self -discharge, the battery is easy to scrap for a period of time; the discharge multipliers are small, and it cannot be discharged for a long time.
