Which is the comparison between alumina battery and lithium battery?

There are three types of batteries commonly used, lead batteries, nickel-metal hydride batteries, and lithium-ion batteries. Lead storage batteries are commonly used batteries for electric vehicles. The disadvantages are large weight, long life and memory effect. The advantage is low price. Lithium-ion battery is a commonly used battery for general mobile phones. It has the advantages of light weight, large capacity, long life and no memory effect. The disadvantage is poor stability (it is a safety problem). NIMH batteries should be bound between the two. Because the voltage and current of electric vehicles are very high, lithium-ion batteries are the best choice, but due to safety issues, it has been difficult to use them successfully. Only some foreign manufacturers have changed their internal components and added protection circuits better solved the problem. So if you want to buy an electric car with a lithium battery, be sure to check out the battery manufacturer.

Lithium battery is usually a lithium-ion battery. The common simple description is cobalt lithium, manganese lithium and iron lithium. The safety problem of lithium battery used to refer to cobalt lithium, but the technology continues to improve, the current manganese lithium and iron Lithium can guarantee safety problems. Otherwise, most of the products that use lithium batteries, such as power tools and IT products are not time bombs. Especially iron-lithium batteries will be the most efficient batteries for electric vehicles in the next few years. For example, BYD's "iron battery" for electric vehicles is actually a lithium-lithium battery.

The cycle life of lead-acid batteries is about 300 times, the cycle life of manganese-lithium batteries reaches 500-800 times, the cycle life of iron-lithium batteries reaches 2000 times, and the new lithium-ion power of Toshiba reaches 5,000 times.

Lead-acid battery charging time is generally 6-8 hours or more, lithium battery uses a dedicated charger, charging time is only 2-3 hours, Toshiba new lithium battery charging can restore 90% of electricity in a few minutes.

The 48V10Ah lead-acid battery weighs about 17 kilograms, while the same capacity lithium battery is only 3-5 kilograms.

Lead-acid batteries will have a capacity drop of more than 40% in winter, and lithium batteries have good temperature suitability. Even in winter at -20 °C, their capacity drops by no more than 15%.

The hazards of lead are not much to say. Lithium batteries do not pollute the environment during production and use.

The most important cost issue is that lithium battery cost is not much more expensive than lead acid. In the case of small energy storage batteries, lithium battery is more competitive than lead acid. At present, the reason why lithium battery is expensive is because its technology is still improving, the old production process is quickly eliminated, and the manufacturer has to recover the cost in a short time. There must be a higher profit rate than other industries. When the technology is mature, the industry scale is formed, and the lithium battery The price will definitely be cheaper than lead acid.

Of course, technology is constantly improving. The replacement of lead acid in lithium battery is not the direction of the future battery. Lithium battery is not a revolutionary technological advancement. The scientific community is more inclined to the direction of fuel cells. For the foreseeable future, the fuel cell may be The most ideal solution for human energy storage.

Lead-acid batteries are safe, durable and low cost, making them suitable for civilian use. There are many types of lead-acid batteries. There are electric vehicles for electric vehicles, batteries for UPS, and batteries for starting batteries. You can choose the right lead-acid battery according to your field of use. It cannot be mixed. The functions are different. Life in the field can be greatly affected.

General warranty for one year, your battery is your own for a long time, there is dormancy, you need to charge the charger with the electrolyte, about 5-6 hours can be used, the dry battery is added within about 90 days after leaving the factory The electrolyte can be used after standing for half an hour, but it takes a long time to activate.

A lead-acid battery (VRLA) is a battery whose electrode is mainly made of lead and its oxide, and the electrolyte is a sulfuric acid solution. When the lead-acid battery is charged, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In the discharge state, the main components of the positive and negative electrodes are lead sulfate. A single-lead lead-acid battery has a nominal voltage of 2.0V, can be discharged to 1.5V, and can be charged to 2.4V. In applications, 6 single-cell lead-acid batteries are often used in series to form a 12V lead-acid battery. There are also 24V, 36V, 48V and so on.

It may be that I have a shallow understanding, I really have never heard of an alumina battery. Lead-acid batteries are safe, durable and low cost, making them suitable for civilian use. There are many types of lead-acid batteries. There are electric vehicles for electric vehicles, batteries for UPS, and batteries for starting batteries. You can choose the right lead-acid battery according to your field of use. It cannot be mixed. The functions are different. Life in the field can be greatly affected.

1. After each use, fully charge as soon as possible. The battery is damaged by a loss of electricity.

2. Do not expose to the sun under the sun, when the battery is too hot, the use of the battery is likely to lead to thermal runaway, serious drums, scrapped.

3. Do not invert the battery when it is charged or discharged or used. If there are conditions, it can be placed on the side for ten minutes when charging, but avoid electrolyte flow. This allows the bottom electrolyte to be mixed repeatedly with the top. Avoid electrolyte stratification.

4. When charging, you can float properly (continuous use of constant voltage or small current, about 0.001C), can effectively avoid the passivation of positive and negative active substances.

5. Under conditions, you can properly over-discharge, that is, use no electricity, stop for ten minutes, continue to put no electricity. Then charge immediately, this is called deep discharge, and it is also effective to avoid passivation of positive and negative active materials.

6. Check if the electrolyte is dry (observe the electrolyte wetting and liquid level of the upper diaphragm under floating charge). This basically users do not have this ability and condition.

After using the lead-acid battery for a period of time (months), a deep charge and discharge can be performed, and the capacity will rise, but avoid frequent deep discharge. Frequent deep discharge will consume the battery life.
