Comparison of advantages and disadvantages of lithium batteries and lead-acid batteries

Lithium batteries generally have a life span of about 5 to 6 years, and the warranty period is generally about 3 years. This is much more than the average battery's life span of only one year or one and a half years, so there is no need to worry about changing the battery every year. And consumers using lithium batteries are about 100 yuan lower than the annual battery usage rate of ordinary electric vehicles.

3, lithium battery electric vehicle lithium battery is safer than ordinary batteries, the lithium battery in other ordinary batteries have a qualitative difference, when there is pressure, impact, short circuit, and other circumstances will not explode.

Lithium batteries are greener than ordinary batteries and have little environmental pollution because long service life can avoid environmental pollution caused by the replacement of ordinary batteries.

lithium battery Electric Vehicles Because the battery is small in size and low in weight, it is generally light and beautiful, easy to move, and many Lithium battery electric vehicles can also be folded.

When consumers charge ordinary lead-acid battery electric vehicles, they have always been worried about the memory effect of batteries. When lithium batteries are used, everyone can relax. Lithium batteries do not have memory effects.

1. Rechargeable batteries(alkaline batteries-lead-acid batteries)

2. Recycling life(1200 to 2000 times-500 to 900 times)

3. Specific energy(150W · h/kg-40W · h/kg)

4. Charge time(2 to 4 H-fast charge 3 to 6 H(fast charging technology is not yet mature) slowly charge at 8h or more)

5. Charge and discharge electric energy efficiency(Lithium-ion battery charged and discharged electric energy conversion efficiency can be greater than 97 %-lead-acid battery charge and discharge electric energy conversion efficiency is about 80 %)

6. Price(higher 24V/10Ah price: 750 to 1200 yuan-lower 24V/12Ah price: 200 to 300 yuan)

7. Volume(the volume of a small lithium-ion battery is 2/3 of the volume of a lead-acid battery-large size)

8. Weight(lightweight is only 1/3 to 1/4 of lead-acid battery-weight)

9. Range(Power-Environmental)

10. There is no pollution in production and use(there is pollution in production-there is a large amount of lead in lead-acid batteries, which will cause pollution to the environment if properly disposed of after disposal).

11. Lithium-ion batteries(charging at constant current-constant pressure-lithium batteries are vulnerable to overcharging, deep discharge and short circuit damage)

12. Charging and maintenance(complex, high maintenance cost-simple, low maintenance cost provides open circuit)

13. Power supply(small open circuit power supply, more series-large open circuit power supply provided)

"Lithium battery" is a type of battery that uses lithium metal or lithium alloy as a negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by GilbertN. Lewis. In the 1970s, M.S. Whittingham proposed and began to study lithium-ion batteries. Due to the very lively chemical properties of lithium metals, the processing, preservation, and use of lithium metals require very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become the mainstream.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and can be charged. The fifth-generation lithium metal battery of rechargeable batteries was born in 1996, and its safety, specific capacity, self-discharge rate, and performance price are better than those of lithium-ion batteries. Due to its own high-tech requirements, companies in only a few countries are now producing this lithium metal battery.
