What are the types of power batteries? What are the main types of power batteries?

There are lithium power batteries, nickel-metal hydride rechargeable batteries, fuel cells, etc.

1) Lithium power battery.

Lithium-iron battery is a new type of green high-energy chemical power supply launched by the United States Yongbei Company after 2000 and has been successfully marketed, and has shown very superior performance in electronic equipment and electric toys that require high-energy and high-power power supply. When the discharge current is above the medium current, the discharge time of the lithium-iron battery can reach about 6 times that of the alkaline manganese battery; Compared with nickel-metal hydride batteries, its discharge voltage platform and storage time have significant advantages.

2) NiMH rechargeable battery.

The use of nickel-metal hydride battery can quickly charge and discharge process, when the car is running at high speed, the electricity generated by the generator can be stored in the vehicle-mounted nickel-metal hydride battery, when the car is driving at low speed, usually consumes a large amount of gasoline than the high-speed driving state, so in order to save gasoline, the vehicle-mounted nickel-metal hydride battery can be used to drive the motor to replace the internal combustion engine at this time, so that the normal driving of the car is guaranteed, and a large amount of gasoline is saved.

3) Fuel cells.

A fuel cell is a device that converts chemical energy directly into electrical energy, its positive electrode is an oxygen electrode, and the negative electrode is a fuel electrode such as hydrogen or hydrocarbons or ethanol. The catalyst catalyzes the reduction reaction of oxygen at the positive electrode, and conducts electrons from the external circuit to the reaction site of the oxygen electrode. The oxidation of the fuel is catalyzed at the negative electrode, and electrons are conducted from the reaction site to the external circuit.

The electrolyte transports the ions produced by the reaction between the fuel electrode and the oxygen electrode and prevents the transfer of electrons. Electrons do work through external circuits and form an electrical circuit. As long as fuel and oxygen are continuously supplied to the battery from the outside of the device, discharge products are continuously discharged from the device (hydrogen-oxygen fuel cells).

Power batteries include nickel-metal hydride batteries. Ternary lithium battery.

It is divided into primary batteries, secondary batteries, reserve batteries and fuel cells.

There are several types of power batteries, such as nickel-cobalt-manganese oxide lithium batteries, lithium manganese oxide batteries, and lithium iron phosphate batteries

1. Lithium nickel-cobalt-manganese oxide battery.

Due to the lack of cobalt resources and nickel and cobalt high and large fluctuations, it is generally believed that it is difficult to become the mainstream of power lithium-ion batteries for electric vehicles, but it can be mixed with spinel lithium manganese oxide within a certain range.

2. Lithium manganese oxide battery.

Lithium manganese oxide battery refers to the battery with lithium manganese oxide material for the cathode, which is a cathode material with low cost, safety and low temperature performance, but the material itself is not very stable and is easy to decompose and produce gas, so it is mostly used for mixing with other materials to reduce the cost of battery cells.

However, its cycle life decay is fast, easy to bulge, high temperature performance is poor, and the life is relatively short, mainly used in large and medium-sized battery cells, power batteries, and its nominal voltage is.

3. Lithium iron phosphate battery.

Lithium iron phosphate battery refers to a lithium-ion battery that uses lithium iron phosphate as the cathode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material used in most lithium-ion batteries.

Pros:

Lithium-ion power batteries have the following advantages: high working voltage; High specific energy; Small size; Light weight; Long cycle life; Low self-discharge rate; No memory effect; No pollution, etc.

NiMH rechargeable battery: The use of NiMH battery can be used to quickly charge and discharge the process, when the car is running at high speed, the electricity generated by the generator can be stored in the on-board NiMH battery, when the car is driving at low speed, it usually consumes a lot of gasoline than the high-speed driving state.

Fuel cell: A device that converts chemical energy directly into electrical energy, its positive electrode is an oxygen electrode, and the negative electrode is a fuel electrode such as hydrogen or hydrocarbons or ethanol.

Lead-acid batteries: widely used as a starting power source for internal combustion engine vehicles. It has good reliability, easy access to raw materials, and low quality; The specific power can also basically meet the dynamic requirements of electric vehicles.

Sodium-sulfur battery: Sodium-sulfur battery can be discharged with high current and high power. It can release three times the intrinsic energy in an instant, and the charging and discharging efficiency is high.

The main types of electric vehicle batteries are as follows:

1. Lead-acid battery.

2. Nickel-metal hybrid battery (for electric vehicles).

3. The lithium-ion battery was first successfully developed by Sony Corporation of Japan in 1990. It is the embedding of lithium ions into carbon (petroleum coke and graphite) to form an anode (traditional lithium batteries use lithium or lithium alloy as the anode). LixcoO2 is commonly used as a cathode material

Also with LixNiO2, and LixMnO4, electrolyte with LiPff6 + diethylene carbonate (EC) + dimethyl carbonate (DMC).

4. Fuel cells.

Ternary power battery, lithium iron phosphate battery, lithium titanate battery, lead-acid battery.

At present, new energy passenger cars mainly use ternary power batteries, new energy buses mainly use lithium iron phosphate batteries, low-speed vehicles, electric bicycles and other lead-acid batteries used to be more, and now they also tend to use lithium iron and ternary.

Power batteries for new energy vehicles mainly include lead-acid batteries, nickel-metal hydride batteries, lithium batteries, and hydrogen fuel cells. At present, lithium batteries have great advantages in energy density, life and environmental performance, and are the first choice for power batteries.

Pure electric vehicles were the first to use lead-acid batteries, lead and its oxide are made as electrode materials, sulfuric acid solution as electrolyte, which is the power source of most battery cars now, and low cost is its biggest advantage. But it has two major drawbacks; First, the specific energy is low, the mass and volume occupied are too large, and the mileage of a single charge is short; The other is that the service life is short and the cost of use is too high.

NiMH battery is a new type of green battery developed in the nineties of the twentieth century, which has the characteristics of high energy, long life and no pollution. Compared with lead-acid batteries, nickel-metal hydride batteries have a lot of improvements, and the electrolyte is non-flammable, the safety is guaranteed, and the manufacturing process is mature. However, the charging efficiency of nickel-metal hydride batteries is average, and high-voltage fast charging cannot be used, so after the widespread introduction of lithium batteries, nickel-metal hydride batteries also have a tendency to be completely replaced in automobiles.

Lithium battery is the mainstream choice of new energy vehicles at this stage, lithium compounds (lithium manganese oxide, lithium iron phosphate, etc.) as electrode materials, graphite as anode materials, its advantages are light weight, large energy storage, no pollution, no memory effect, long service life.

In the case of the same volume and weight, the storage capacity of lithium batteries is twice that of nickel-metal hydride batteries, and human beings have only developed and utilized 20% 30% of its theoretical power, and the development prospects are very bright. However, no matter what type, all lithium battery packs will face the "natural enemy" of low temperature.

Hydrogen is an ideal clean energy source. It is characterized by no pollution, no noise, high efficiency, as far as hydrogen itself is concerned, combustion can release a lot of energy, low temperature performance is good, and the most important thing is that the efficiency of hydrogen refueling is high, and hydrogen refueling can travel more than 600 kilometers in just 5 minutes. And there is still room for improvement in this data, which is far better than the existing lithium batteries.

However, hydrogen fuel cell cars weigh more than 200 kilograms and are more than 5 times more expensive than diesel locomotives of the same type. As for the investment of hydrogen fuel cell vehicles, car companies in Japan and South Korea have been researching for a long time, and now they have invested in the markets of their respective countries on a small scale.

What are the types of automotive power batteries? Most of the existing power batteries are lead-acid batteries and lithium-ion batteries (lithium iron phosphate batteries or ternary batteries). A small number of useful nickel-metal hydride batteries, as well as capacitors, etc.

Japanese, German, and recently domestically produced CATL are also good.

BAI is used as a power source (or using conventional vehicle fuel, using a new type of on-board DAO power unit), integrating advanced technology in vehicle power control and drive, forming a car with advanced technical principles, new technologies and new structures. New energy vehicles include four types of hybrid electric vehicles (HEVs), pure electric vehicles (BEVs, including solar vehicles), fuel cell electric vehicles (FCEVs), and other new energy vehicles (such as supercapacitors, flywheels and other high-efficiency energy storage) vehicles. The promotion of new energy vehicles is to cope with the needs of environmental protection and the oil crisis, and to reduce or abandon the current mainstream models that burn traditional gasoline or diesel to drive internal combustion engines.

The Roewe ER6 pure electric battery uses a ternary lithium battery of NCM523 cells, which is placed at the bottom of the car, and an explosion-proof valve and a balance valve are designed on the battery shell to reduce the probability of harm by adjusting the battery state in time.

Through years of accumulation, SAIC has a complete new energy system and profound technology accumulation. As the first model in the R brand's ER series, the ER6 is equipped with a highly integrated electric drive system and a reliable battery system to achieve a range of 620 km.

Power battery module.

Battery cell: The smallest unit that constitutes a power battery module. It is generally composed of a positive electrode, a negative electrode, an electrolyte and an outer shell. It can realize the direct conversion between electrical energy and chemical energy;

Battery module: the combination of a group of battery cells connected in parallel, and the rated voltage of this combination is equal to the rated voltage of the battery cell, and is the smallest grouping of battery cells connected in the physical structure and circuit, and can be replaced as a unit;

Module: A combination composed of multiple battery modules or single cells connected in series.

The C30DB project uses a lithium-ion power battery system, which is a rechargeable battery, which mainly relies on lithium ions to move between the positive and negative electrodes to work. When charging, lithium ions are de-intercalated from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; The opposite is true when discharging. Lithium-ion batteries can be divided into lithium cobalt oxide batteries, lithium manganese oxide batteries, lithium iron phosphate batteries and three-element batteries according to the different cathode materials.

From the perspective of energy access, there are three main types of fatigue:

1. Energy storage batteries (can be divided into many types);

2. a fuel cell;

3. Photovoltaic cells (currently unable to directly drive the car, and need to be used in conjunction with energy storage batteries);

Lithium iron phosphate batteries and ternary batteries are commonly used.
