High energy density
Compared with other batteries, the energy density of lithium batteries is very high, and it has reached 460-600Wh/kg, which is about 6 to 7 times that of lead-acid batteries. This means that under the same charge capacity, the lithium battery is lighter. According to calculations, the weight of the same volume is about 1/5 to 1/6 of that of lead-acid products.
No memory effect
Lithium batteries have no memory effect, which means that they do not require a fixed amount of electricity to be charged like nickel-cadmium batteries. They can be charged as they go according to their actual needs, giving users a more efficient and convenient experience. The operating temperature of lithium batteries is usually between -20°C and 60°C, but some specially customized lithium batteries can be more adaptable to temperature, and some can even operate normally in an environment of hundreds of degrees Celsius.
Composition materials are environmentally friendly
LixCoO2, LixNiO2, and LixMnO4 are commonly used as positive electrode materials for lithium batteries, and LiPF6+diethylene carbonate (EC)+dimethyl carbonate (DMC) is used for the electrolyte. Petroleum coke and graphite are non-toxic and abundant resources as negative electrode materials. Lithium ions are embedded in carbon, which overcomes the high activity of lithium and effectively solves the safety problems of traditional lithium batteries. The positive electrode LixCoO2 can reach a higher level in terms of charge and discharge performance and lifespan, which reduces the cost and improves the comprehensive performance of the lithium battery.
Compared with materials such as sulfuric acid solution, lead and its oxides in lead-acid batteries, the composition of lithium batteries has a great guarantee for the environmental protection and safety of users and the surrounding environment. Lithium battery used as energy storage power supply for UPS power supply has many advantages. Compared with lead-acid battery, it also has higher use efficiency. Many, when users choose UPS power supply, they also favor lithium battery UPS.
