1. High energy density. The high storage energy density has reached 460-600wh/kg, which is about 6-7 times that of lead-acid batteries.
2. Long service life. The service life is more than six years. The battery is charged and discharged with a lithium iron phosphate battery as the negative electrode. The use time record can be used for 10,000 hours.
Lithium-ion batteries are generally used in automobiles because lithium-ion batteries are relatively large, the circulatory system has a long life, and there is no memory. There are two key methods for charging automotive lithium-ion batteries, random charging and full cycle charging.
3. High additional voltage. (Single standard voltage) is basically equivalent to the series voltage of three nickel-cadmium or nickel-hydrogen rechargeable batteries, and it is easy to form a battery pack.
Lithium-ion battery cathode materials include lithium cobalt, lithium manganese, lithium nickel, ternary materials, lithium iron phosphate and so on. The full name of lithium iron phosphate battery is lithium iron phosphate lithium ion battery, or lithium iron phosphate battery for short. Therefore, the thinner the battery, the lower the polymer production cost, and the higher the liquid production cost.
4. Lithium iron phosphate lithium ion batteries for pure electric vehicles have good carrying capacity, which can reach 15-30c battery charge and discharge capacity;
5. Low self-discharge rate This is the advantage of the battery. At this stage, it is generally 1% per month, which is much lower than 25% nickel cadmium and 30% nickel and mh.
The decrease rate of continuous charge and discharge batteries is slower, and the charge and discharge rate is lower than that of single pulse batteries. Since the introduction of the energy-saving and new energy automobile industry development plan, government subsidies, tax reductions and other measures have enabled the rapid development of my country's new energy automobile industry chain. In addition, considering the rational layout of the entire industry chain and the advantages of raw materials in the power lithium-ion battery industry , The new energy vehicle market has always been at the forefront of the world.
6. The net weight of a lead-acid battery with the same volume is about 1/5-1/6.
From upstream raw materials to downstream rechargeable batteries, how many lead-acid batteries have not been defeated before the lithium-ion batteries related to domestic listed companies? In addition to traditional digital technology, industries such as new energy vehicles have been occupied by lithium-ion in recent years, and the now-retired lithium-ion batteries have robbed the lead-acid battery sales market for birthday cakes.
7. High and low temperature applicability, can be used in the range of -20c to 60c, and can also be used in the range of -45c.
8. Green and ecological environment protection, even if it is manufactured, applied or processed, it does not contain or cause harmful heavy metal elements and chemical substances, such as lead and cadmium.
9. Most of the production does not consume water, so it is very beneficial to water shortage.
