What are the advantages and disadvantages of lead-acid batteries?

Advantages:

1 Long lifetime

2 Low prices

3 Can be discharged in large current

Disadvantages:

1 The pollution of lead

2 Energy density is low, means it is too big and heavy

Lithium-ion battery on electric vehicles and pros and cons of lead-acid battery

First, long lifetime

Cycle life of lead-acid battery is controlled in 200, the highest is 300 times. And lithium ion battery cycle life reached more than 300 times, the standard charging rate (5 hours) to use, up to 500 times, even more than 1000 times. Lead-acid battery also can use at most 1-1.5 years, and lithium ion battery used under the same conditions, will be three years.

Second, safe using, good performance

Lithium ion battery completely solve the problem of the lead-acid battery safety concerns. Lead-acid battery can produce explosion under the intense collision, pose a threat to consumer's life safety. And the safety of the lithium ion battery through strict test does not produce explosion.

Third, no memory effect

Rechargeable batteries after are often filled with not to put under the conditions of work, capacity quickly is lower than the rated capacity values, this phenomenon is called memory effect. Battery and lithium ion batteries do not have this phenomenon, no matter in what condition, can use increases with the increasing charge, do not need to first put the recharging.

Four, small volume, light weight, long time

Same specification volume of lithium ion battery capacity is two-thirds the size of lead-acid battery, weight is 1/3 of the lead-acid battery.

Fifth, expensive

Lithium ion battery of electric cars more expensive than lead-acid batteries of electric cars.

Six, environment friendly

Of lead-acid battery there are a lot of lead in lead-acid batteries in electric cars, after waste if not handled properly, it will produce pollution to the environment, and lithium materials do not have any poisonous and harmful substances, is considered by the world of green environmental protection battery, the battery in both production and use of pollution-free, become a widely concerned research hot spot.

Lithium-ion battery, lead-acid 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 Pool ", 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 GilbertN. 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 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.

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 (the provided open circuit is small, more series connections-- provides more open circuit of power supply)
