Comparison of advantages and disadvantages between lithium-ion battery and lead-acid battery

Lithium-ion batteries and lead-acid storage battery

1. The rechargeable battery (alkaline battery, lead acid battery)

2. The circulation service life (1200-2000-500-500)

3. The specific energy (w. h/kg 150-40 w. h/kg)

4. The charging time (2 ~ 4 h - quick charge 3 ~ 6 h (fast charging technology has yet to mature) slow filling in more than 8 h)

5. Charge and discharge energy efficiency (lithium ion battery charging and discharging power conversion efficiency can be greater than 97%, lead-acid battery charge and discharge electricity energy conversion efficiency is about 80% or so)

6. Price (24 v / 10 ah high price: 750 ~ 1200 yuan - 24 v / 12 ah low price: RMB 200 ~ 300)

7. Volume (the volume of a small volume of lithium ion battery is two-thirds the size of lead-acid battery, large volume)

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

9. Range (power, environmental protection)

10. No pollution in the production and use of (there is pollution in production - there are a lot of lead in lead-acid battery, if mishandled, after waste will produce pollution to the environment).

11. Lithium ion battery (in constant circulation of constant voltage charging way --The lithium battery vulnerable to overcharge, deep discharge and short circuit damage)

12. The charging and maintenance (complex, high maintenance cost, simple, low maintenance costs provided by the open circuit)

13. Power supply (provided by small power supply, open series -- provides more open circuit of power supply)

"Lithium electricity ", is a kind of lithium metal or lithium alloy anode materials, the use of water battery electrolyte solution. Lithium battery as early as 1912 by Gilbert N. Lewis is put forward in this study. In the 1970 s, M.S.W Hittingham and began to research on lithium ion battery are put forward. Due to the lithium chemistry is very lively, making lithium metal processing, storage, use, very high demand on the environment. So, the lithium battery has not been applied for a long time. With the development of science and technology, the lithium battery has now become the mainstream.

Lithium-ion battery can be roughly divided into two categories: lithium battery and lithium ion batteries. Lithium-ion battery does not contain lithium metal state, and can be recharged. The fifth generation of rechargeable battery product lithium battery was born in 1996, its security, specific capacity, self-discharge rate and cost performance is better than that of lithium ion batteries. Because of its high technical requirements limit, now only a few countries in the production of this kind of lithium battery.

10. No pollution in the production and use of (there is pollution in production - there are a lot of lead in lead-acid battery, if mishandled, after waste will produce pollution to the environment).

11. Lithium ion battery (with constant flow constant pressure method for charging, lithium batteries are susceptible to recharge, deep discharge and short circuit damage)

12. The charging and maintenance (complex, high maintenance cost--simple, low maintenance costs provided by the open circuit)

13. Power supply (provided by small power supply, tend to connect in series -- provides larger power supply of open circuit)
