Which one has longer cycle life, lithium battery or lead-acid battery?

Because LiFePO4 has a stable oxidation state, good safety performance, high temperature performance, non-toxic, non-polluting, wide range of raw materials, and low price, LiFePO4 is considered as a new generation of positive electrode that is highly likely to replace existing materials. The phosphate cathode material represented by it is expected to be beneficial to solve the problems of poor safety of the current large-capacity lithium ion battery, and further expand the application space of the lithium ion battery.

Compared with other types of batteries such as lithium batteries, nickel cadmium, and nickel hydrogen, lithium iron phosphate batteries have high capacity density. 2) Recharge and discharge more than 2000 times. 3) The internal resistance is small and the self-discharge rate is low. 4) No "memory effect". 5) High security

The role of car batteries for cars is not only the radios that we can listen to, the lights that are turned on, and the car air conditioners. One of the most important functions is that the work of car starters also needs batteries to drive, that is, The battery is dead, or it is broken, and the car's ignition is a problem. How long can our car battery last? What should I pay attention to in order to make it last longer?

Just now, when the car is on fire, the battery will be discharged to the starter, and the starter will then drive the engine flywheel and crankshaft to start the car. Before the car starts, if we listen to music, listen to radio, drive lights, driving recorders, electronic handbrakes, etc., all of the electricity needs are powered by batteries.

When the engine is started, at this time, the power output from the engine will also drive the generator. At this time, the output voltage of the generator will be slightly higher than the battery. At this time, the battery will be converted to the charged state, and the power supply will be converted to generate electricity. The machine is the main type, and the battery is a form of auxiliary.

The storage capacity of our batteries is actually very limited. The two 55W headlights have been kept on. It will take about 5 hours to drain a 12V60A battery. In addition, the load of the battery at the moment of the starter ignition is relatively large, and it is also a factor that has a relatively large impact on the battery life.

Lead-acid battery life and how long _ lithium battery life of the pool which long

Generally, we use the car normally. The life of the car battery is about 3 years. If the number of times of the battery, the load, and the time are too long, the life may be shorter. For example, what habits will cause more battery power? After we stopped the car, we listened to the radio in the car; after the flame was turned off at night, the headlights were forgotten to turn off; and when we modified some electrical equipment, such as the driving recorder, we like to take power directly from the battery, which will reduce the battery. The life span; there are frequent starting engines, the instantaneous load on the battery is also very large, so many of our friends' cars have a start-stop function, and more worried about the battery life.

In fact, the battery with start and stop cars is quite special, called AGM type battery, the battery's cycle charging ability is about 3 times higher than our ordinary lead-acid battery capacity.

How long is the life of a lead-acid battery?

The life of the lead-acid battery used in most of our cars is relatively short, and it will take about 2 to 3 years. However, there is an advantage that the electrode of the battery is composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. If the battery cannot be charged and discharged, the distilled water can be replenished, and it can last for another 1-2 years. .

The other is called a maintenance-free battery. It seems that the name is relatively bullish. Yes, its biggest advantage is that it has a longer life than a lead-acid battery. It does not require maintenance or add distilled water. It can be said to be disposable. Just change. Its life is generally twice that of ordinary batteries.

How long is the life of a lead-acid battery?

So, let's summarize, how can we extend the life of our batteries?

First of all, we have to change our habit of Ma Daha first, like what to forget to turn off the headlights after parking; in addition, use as little as possible in the car when the car is turned off, the radio, the headlights of. In addition, if you do not use external electrical equipment as much as possible in the case of flameout, it will damage the battery and affect the life.

lithium battery. A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, MSWhitTIngham proposed and began researching lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream.

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 discharged, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In the state of charge, the main components of the positive and negative electrodes are lead sulfate.
