When buying a new energy vehicle, how much do you know about its battery life? What are the impacts of batteries on performance in new energy vehicles? Shandong Dejin New Energy will learn some things about batteries together with you.
In general, there are three main types of batteries in the automotive field: chemical batteries, physical batteries, and biological batteries. Let's introduce them separately below:
1. Storage battery, also known as secondary battery, is because after the storage battery is discharged, it can regenerate the internal active material by charging, thereby storing electric energy as chemical energy; when it needs to be discharged, the chemical energy is converted into electric energy again. The battery of a mobile phone is also a storage battery. Lead-acid batteries and nickel-metal hydride batteries are the most commonly used car batteries.
Lead-acid batteries were once commonly used as internal combustion engine cars. Its reliability is good, raw materials are easily available, and the price is low; it can basically meet the requirements of electric vehicles for power performance. However, lead-acid batteries have small specific energy, large mass, large volume, short charging mileage, short life, and high cost, which cannot meet the development needs of new energy vehicles in the future.
Nickel hydride batteries have more energy storage, lighter weight, longer life and no pollution to the environment, but their manufacturing costs are too high and their performance is poor.
2. A fuel cell is a power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy through an electrochemical reaction. It is the fourth power generation technology after hydropower, thermal energy and atomic energy. It has the advantages of high power generation efficiency, low environmental pollution, high specific energy, low noise, large combustion volume, high reliability, and simple construction. It is currently recognized as a power generation technology with great development prospects. It is mainly used in the field of space flight and has not yet been commercialized for civilian use.
Lithium battery is a kind of physical battery that uses lithium metal or lithium alloy as positive/negative material. It uses non-hydrolyzed solution. At present, lithium batteries are commonly used in electric vehicles and new energy vehicles, and their main advantages include:
(7) Green and environmental protection, no matter it is produced, used or discarded, it does not contain or manufacture toxic and harmful heavy metal elements, such as lead, mercury, cadmium, etc.
Lithium batteries for electric vehicles currently on the market mainly include lithium cobalt oxide batteries, lithium iron phosphate batteries and ternary lithium batteries.
Lithium cobalt oxide battery has mature production technology, high energy ratio, but poor stability. Usually used in laptop batteries.
At present, lithium iron phosphate batteries for automobiles are relatively stable, but have low energy density and are not suitable for low-temperature environments. Therefore, models of lithium iron phosphate batteries are not suitable for driving in the north.
Compared with lithium cobalt oxide batteries, ternary lithium batteries are safer and more stable at low temperatures, which is more in line with the future development trend of new energy vehicle batteries. But its voltage is low, and its energy density is between lithium iron phosphate batteries and lithium cobalt oxide batteries.
Although these three types of lithium batteries have been widely used in various areas of life, they all have certain safety hazards and are prone to explosion accidents. For example, battery accidents have occurred in both Samsung and Apple mobile phones; at the same time, the production conditions for lithium batteries The requirements are high and the cost is high. Some lithium batteries have restrictions on the ambient temperature of use, and high or low temperatures are risky. Therefore, the development of more efficient and safer batteries is still an important research topic.
Nowadays, in addition to the above-mentioned three kinds of ordinary batteries, graphene batteries with greater advantages have gradually entered the R&D vision of major automobile manufacturers. Graphene is added to the lithium battery to develop a new type of energy battery. The graphene battery has a short charging time, which can compress several hours of charging time to less than one minute. The composition of graphene can help the lithium battery reduce heat when it is working, so as to reduce energy loss and reduce heat damage to the battery, thereby extending The service life of the battery. However, graphene batteries are currently too expensive to be used on a large scale.
"Bio battery" is a device that directly converts biological energy into electrical energy. In 2013, scientists discovered that the energy produced by bacterial epidermal proteins can be collected into electrical energy. As an important development direction of electric vehicle batteries. The existing bio-battery technology is mainly to provide power for spacecraft and has not yet been implemented in the civilian field.
