Comparative analysis of lithium battery and lead acid battery
First, the difference between lithium battery pack and lead-acid battery
Lithium battery: A type of battery that uses a lithium metal or a lithium alloy as a negative electrode material and uses a nonaqueous electrolyte solution.
Battery: It is one of the batteries. Its function is to store limited electric energy and use it in a suitable place. It works by converting chemical energy into electrical energy.
Second, from the perspective of weight energy density, volume energy density, service life, price, applicability, charging, etc.
1 weight energy density
The lead-acid battery pack weighs 16-30 kg and has a large volume; while the lithium battery generally weighs 2.5-3.0 kg and has a relatively small volume.
2 volume energy density
The volume capacity density of a lithium battery pack is usually about 1.5 times that of a lead-acid battery, so in the case of the same capacity, the lithium battery is about 30% smaller than the lead-acid battery.
3 service life
The lithium battery of the lithium iron phosphate cathode material can reach about 2000 times, and the number of cycles of the lead acid battery is usually about 300 to 350 times.
4 price
At present, lithium batteries are more expensive than lead acid in price, about three times.
Lithium battery packs are slightly less safe than lead-acid batteries. Therefore, various safety precautions must be taken during use, such as preventing damage to lithium batteries caused by external forces or accidents, as this may cause fire or explosion.
6 charging speed
Lithium batteries have a wide range of charging efficiencies, which is a unique advantage of lithium batteries. When necessary, the charging time can be controlled from 20 min to 1 h, and the charging efficiency is over 84%.
Zhengzhou Kanglida Electronic Power Co., Ltd. was established in 2000, focusing on the production and sales of 4V, 4V, 6V, 12V four series of maintenance-free lead-acid batteries, gel batteries and their electronic chargers. Products through the EU CE, the United States UL certification, MSDS testing, Shanghai Chemical Industry Institute test report, cargo transport conditions identification book, national battery testing center testing.
After 20 years of continuous transformation and growth, Kanglida has become a well-known brand in the domestic industry with its high-quality products and first-class service. It has successfully entered the foreign battery market. The international trademarks have been in 23 countries including the United States, Japan and South Korea. And the region passed, the product information was recorded in the "China Public Safety Industry Guide", "China Public Safety" "Intelligent Security" and recommended to the national security companies. It has won “100 National Honests” for ten consecutive years and was rated as “Advanced Unit of Heavy Quality and Trustworthiness” by Henan TV Station.
