What are the characteristics of lithium-ion power batteries? Detailed explanation of the characteristics for lithium-ion power battery

2021-11-09 11:32

Lithium ion power battery is a new type of high-energy battery which successfully developed in the 20th century. The cathode of this battery uses graphite and other materials, the positive electrode uses lithium iron phosphate, lithium cobalt acid, lithium titanate and so on. Lithium manganese acid, lithium iron phosphate and others as cathode materials for the power battery, are classified as lithium ion power battery, each has its own advantages, which is the development trend of a new generation on the lithium ion power battery. Following shows the characteristics of lithium ion power battery.

High Voltage

The voltage of lithium-ion power battery is 3 times of nickel-cadmium battery and nickel-hydrogen battery, nearly 2 times of lead-acid battery, which is also an important reason for the high specific energy of lithium-ion power battery. Therefore, when forming the power battery pack with same voltage, the number of series used for lithium ion power battery is much less than lead acid battery and nickel-metal hydride battery.

Light Weight

Lithium-ion power batteries have high specific energy, which is up to 150Wh/Kg, twice of nickel-metal hydride batteries and four times of lead-acid batteries. So the weight of lead-acid batteries with the same energy is one third to one quarter. From this point, lithium batteries consume less resources. Therefore, compared with lead-acid and ni-Mh batteries, the price may rise further, while the cost of lithium-ion power batteries is further reduced.

 

Long Life

The cycle times can reach 2000~10000 times. Counting the 70% capacity, the battery pack can be 100% charged and discharged above 200 times, cycle life can reach 5 to 8 years, which is about two to three times comparing with the lead acid battery. With the innovation of technology besides the improvement of equipment, the battery life will be longer and longer, and the cost performance will be higher and higher.

Wide Range

The low temperature performance of lithium ion power battery is good. Lithium ion power battery can work between -40℃ and +55℃. The performance of aqueous solution battery (such as lead-acid battery and nickel-metal hydride battery) will be greatly reduced due to the poor fluidity of electrolyte at low temperature.

No Memory

Lithium-ion batteries have no memory effect, so they don't need to discharge before charging like nickel-cadmium batteries and nickel-hydrogen batteries, and can be charged anytime and anywhere. The depth of charge and discharge of the battery has little effect on the life of the battery. It can be fully charged and discharged. Our cycle test is fully charged and discharged.

No pollution

Lithium-ion power batteries is called "green batteries"  as it doesnt contain toxic substances. And it is supported by the governmentAs lead acid battery and cadmium nickel battery content harmful substances such as lead and cadmium, which inevitably strengthen supervision and governance (lead acid battery export tax rebate cancellation, lead resource tax increase, lead acid electric bicycle export restrictions), the corresponding cost of the enterprise will also increase. Although lithium batteries are not polluting, it is considered from the perspective of resource conservation. The recycling of lithium-ion power batteries, the safety of recycling, and the cost of recycling also need to be considered.

High safety requirements

Due to the high energy and poor material stability of lithium ion power battery,safety problems are prone to occur. The capacity of power battery is more than 100 times comparing with mobile phone battery, which make the safety requirements of lithium electricity extremely high. Although lithium cobalt oxide batteries and ternary batteries have the advantages of lighter weight and smaller size, they are not suitable for electric vehicles as power batteries. Lithium ion batteries with mixed crystal lithium manganate and lithium iron phosphate are the most promising lithium ion power batteries.

Nice Price 

For same voltage and capacity, the cost of Lithium-ion power batteries are 3-4 times higher than lead-acid batteries. With the expansion of the lithium ion power battery market, the reduction of cost, the improvement of performance, and the increased price of lead acid battery, the cost performance of lithium ion power battery is likely to exceed the lead acid battery.

 (sized is customized)


Lithium ion power battery has been widely used in military and civil small electrical appliances due to its advantages of high energy, high battery voltage, wide operating temperature range and long storage life. Lithium-ion batteries have partially replaced traditional batteries in mobile phones, portable computers, video cameras and other applications. Large-capacity lithium-ion batteries have been tried out in electric vehicles and will become one of the main power sources for electric vehicles in the 21st century. They have been applied in artificial satellites, aerospace and energy storage.
