The types of batteries are:
1. Lead-acid batteries
Commonly used lead-acid batteries are mainly divided into three categories: ordinary batteries and dry charge batteries. and maintenance-free batteries, the plates of ordinary batteries are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main characteristic of dry charge batteries is that the negative plate has high energy storage capacity. Maintenance-free batteries have structural defects. Advantages: Electrolyte consumption is very low and there is virtually no need to replenish the distilled water during the shelf life.
Lead-acid batteries are widely used in electric power, energy storage, electric vehicles and other fields. Particularly, its advantages such as mature technology and low cost make itdifficult to replace it with other battery products in the short term.
2. UPS Battery
The UPS is called uninterruptible power supply because in the event of a power outage, it can quickly switch to the "inverter" state, preventing the use of the battery. . The computer loses important files due to a sudden power outage before it has time to store them.
3. Lithium iron phosphate battery
Lithium iron phosphate battery is the safest specific energy battery in the lithium-ion battery family. The discharge voltage is very stable, generally 3.2V. When discharged to The voltage changes rapidly when 10% remaining capacity is reached and the cut-off voltage is typically 2.5V.
4. Great battery
Great battery. It is also an engine starting power supply. This is a device that can provide starting power to the wordinternal combustion engine through rapid energy storage when the traditional battery equipped with the internal combustion engine fails and cannot start.
The battery is a widely used chemical “energy source” around the world. It has the advantages of stable voltage, safety and reliability, low price, wide application range, abundant raw materials and high recycling rate. the most produced and used battery among batteries.
Some issues that should be paid attention to when using and maintaining batteries:
1. If the battery is not used for a long time, it will slowly discharge until it is completely empty. discarded. Therefore, the car must be started at regular intervals to charge the battery.
2. When the ammeter pointer indicates that the battery capacity is insufficient, charge it in time. Battery capacity can be reflected on the dashboard.
3. The density of the electrolyte should be adjusted accordingly according to the standards of different regions and seasons.
4. If electrolyte loss occurs, distilled water or a special rehydration solution should be added. Do not use plain water instead. Since pure water contains various trace elements, it will have adverse effects on batteries.
5. When starting the car, continued use of the starter motor may damage the battery due to over-discharge.
6. When driving daily, you should always check whether the small hole on the battery cover is ventilated. If the small hole in the battery cover is blocked, the hydrogen and oxygen generated cannot be discharged. When the electrolyte expands, it will cause the battery shell to burst and affect its service life.
7. Check the positive and negative stages of the battery for signs of oxidation. You can pour hot water on the battery wires from time to time. The joints were cleaned with a copper wire brush and greased with butter.
8. Check for aging or short circuits in all parts of the circuit. Prevents the battery from prematurely discharging due to over-discharge.
Whether it is better to use lithium batteries or storage batteries for trams
No.
There are two types of lithium batteries:
Lithium-ion batteries do not contain metallic lithium and are rechargeable.
Lithium metal batteries are disposable batteries and cannot be recharged.
Non-rechargeable batteries are called disposable batteries. They can only convert chemical energy into electrical energy once and cannot pto restore electrical energy into chemical energy. Such as lithium manganese dioxide primary batteries and lithium thionyl chloride primary batteries.
Rechargeable batteries are called secondary batteries (also called storage batteries). It can convert electrical energy into chemical energy and store it when used, it can convert chemical energy into electrical energy, like common lithium-ion mobile phone batteries on the market.
Detailed information:
Lithium metal battery generally uses manganese dioxide as the positive electrode material, lithium metal or its metal alloy as the negative electrode material, and uses solution non-aqueous electrolytic.
Discharge reaction: Li+MnO2=LiMnO2
Lithium batterieswere first used in cardiac pacemakers. Lithium batteries have the advantages of extremely low self-discharge rate and gentle discharge voltage, allowing pacemakers implanted in the human body to work for a long time without recharging.
Lithium batteries typically have a voltage rating above 3.0 volts and are more suitable for integrated circuit power supplies. Manganese dioxide batteries are widely used in calculators, digital cameras and watches.
Disadvantages:
1. Primary lithium batteries have poor safety and explosion risk.
2. Lithium-ion batteries based on lithium cobalt oxide cannot be discharged at high currents, are expensive and unsafe.
3. Lithium-ion batteries require protection circuits to prevent the battery from being overcharged or damaged.discharged.
4. The production requirements are high and the cost is high.
5. The conditions of use are limited, and the use of high and low temperatures is very dangerous.

Whether it is lead-acid battery or lithium battery, they have their own advantages and disadvantages, so we can't say who is the best, only I can't say which one suits me best. After all, everyone's use situation is different. It is recommended that you refer to the advantages and disadvantages of lead-acid and lithium batteries combined with your actual usage situation. choose an electric vehicle battery that suits you best. byHere are their respective advantages and disadvantages:
Advantages of lead acid batteries:
1. Good performances security. Lead-acid batteries are easy to maintain. You can knock them over, fix them a little and continue to use them.
2. Cheap price. The price of lead-acid batteries is about 1/3 that of lithium-ion batteries, which shows how low the price is.
3. Recyclable reverse repair. Lead acid batteries are highly recyclable. Once worn out, you can go to an electric car store to exchange them for new ones. You can exchange them for a new set of batteries by paying the price difference, thus minimizing losses. a great advantage for users. Battery lead can also be recycled and reused, reducing environmental pollution.
Disadvantages of lead-acid batteries: high weight, limited battery capacity and short lifespan. Lead-acid batteries typically have a lifespan of about three years after 400 charges and discharges.deep ages.
Advantages of lithium-ion batteries:
1: Lightweight and small size. The volume of lithium-ion battery is 2/3 of the volume of lead-acid battery, and the weight is about 1/3 of the weight of lead-acid battery. Lithium-ion batteries of the same volume have a higher capacity than lead-acid batteries. The reduced weight makes electric vehicles lighter and their range is increased by around 10%.
2: Long life. The average lifespan of lithium-ion batteries is about 4 years, about a year longer than lead-acid batteries. It can be charged and discharged more than 500 times. The battery has no memory and is very shock resistant.
3: Resistant to overcharge, good resistance to charge and discharge. At normal temperatures, lithium-ion batteries can be charged continuously for 48 hours without causing expansion, leakage, rupture or other accidentsnts, and the capacity remains above 95%. And with a special charger, it can be charged and discharged quickly.
Disadvantages of lithium-ion batteries:
The production cost of lithium-ion batteries is high, the production equipment is expensive, and the labor costs represent approximately 40% of the production cost. The price is about three times that of lead-acid batteries. At three times the price, it's not great value for money, and it looks rather flashy. Additionally, lithium-ion batteries are not recyclable. Once worn out, they can only be thrown away or buried after thousands of times. years, future generations will not be able to use them. If you dig it up, it will be an antique.
Based on the quality, after-sales service and price of electric vehicle batteries, we recommend several good lead-acid battery brands: Changxin Battery, Shinhwa Battery et Mantingfang Battery.
