At present, energy shortage has become a worldwide problem. In order to alleviate the shortage of oil resources, the development of new energy vehicles that replace traditional fuel vehicles has reached an urgent point. For the time being, countries have made certain achievements in the development of new energy vehicles, including solar energy, hydrogen fuel, and wind energy. One of the most popular and widely used is the lithium-ion battery.


1. An application status of lithium-ion battery for new energy vehicles


At present, the application status of lithium-ion batteries of new energy vehicles shows that the development prospects are good, the technology needs to be perfect; the specific energy is insufficient, and it acts as auxiliary power; the use range is wide, and the types of batteries are many, the specific performance is as follows.


1.1 Good development prospects, technical needs to be improved


Compared with other new energy sources, lithium-ion batteries have been developed and used for a long time in decades, and have certain advantages in terms of battery performance and quality. Most researchers hope to promote the generation and development of new energy vehicles through the improvement of lithium-ion battery application technology. However, China has encountered some difficulties in the development of lithium-ion batteries, for example, lithium-ion batteries are key. Raw materials (positive and negative electrodes, separators, electrolytes, etc.) are also dependent on imports. Some production processes and equipment need to be imported from abroad, which limits the development and manufacturing level of lithium-ion batteries in China to a large extent. It can be seen that although lithium-ion batteries have good development prospects, in the actual application process, researchers still need to increase research and development efforts, and effectively improve the application technology of lithium-ion batteries.


Exploring the application status of lithium-ion batteries for new energy vehicles


1.2 is less than energy, acting as auxiliary power


Specific energy is a statement of the basic concept of battery release energy. The higher the specific energy of a battery, the more it meets the needs of new energy vehicle power. By analyzing the application of lithium-ion batteries, we can find that there are some shortcomings in the specific energy of lithium-ion batteries, which leads to the unsatisfactory driving range of current pure electric vehicles. Therefore, in response to this deficiency of lithium-ion batteries, the hybrid vehicle was developed, and the lithium-ion battery was used as auxiliary power to reduce the amount of fuel.


1.3 Wide range of uses, many types of batteries


Although lithium-ion batteries have certain shortcomings, they still have a wide range of applications. Most countries have made lithium-ion batteries a key research object and have been put into use in a wide range. By analyzing and researching the materials for lithium-ion batteries, we can find that at present, lithium-ion batteries used in the world can be divided into lithium manganate, lithium cobaltate, lithium titanate from the perspective of materials. Lithium iron phosphate, ternary materials and other types among them, lithium cobalt oxide is mainly used for small-capacity batteries such as notebook computers and tablet computers, and other types can be used as large-capacity power batteries, and are widely used in new energy vehicles.


2. Effective ways to promote the development of lithium-ion battery applications in new energy vehicles


2.1 Improve innovation capabilities and develop advanced technologies


In order to effectively promote the development of lithium-ion battery application technology for new energy vehicles, relevant R&D personnel should incorporate innovative spirit into the R&D process in the future work process, and make bold attempts to solve the problems existing in lithium-ion batteries. For example, replacing the material of a lithium-ion battery, or combining a lithium-ion battery with solar energy technology, the lithium-ion battery is charged at a time by converting solar energy into electrical energy. In addition, researchers should also pay attention to the advanced nature of technology. In the process of independent research and development, they should pay attention to the latest technological developments in the world and actively introduce advanced technologies.


2.2 Improve quality standards and improve battery performance


For the time being, lithium-ion batteries are superior to other types of batteries in many ways. However, in the future, in order to become the main power source of automobiles, in addition to improving the specific energy, lithium-ion batteries should also effectively improve the quality of other aspects, such as the storage capacity, charging speed and usage time of lithium-ion batteries. Wait. In view of this, relevant R & D personnel should appropriately improve the quality standards of lithium-ion batteries, strictly manage the application requirements of lithium-ion batteries, and improve the performance of lithium-ion batteries by continuously improving the quality of lithium-ion batteries.


2.3 Increase policy support and focus on positive guidance


It is difficult to rely solely on the company's own research and development of lithium-ion batteries for new energy vehicles. Whether it is technical support or supply of funds, it has obvious limitations. Therefore, the Chinese government should pay attention to the application of lithium-ion batteries for new energy vehicles, and introduce some support policies to encourage enterprises to carry out related research and development. For example, companies that develop new energy vehicles are given tax-free or preferential treatment. Or arrange relevant experts to guide the R&D enterprise. Through the positive guidance of the government, the majority of auto companies can see the development potential of new energy vehicles and actively invest in the research and development of lithium-ion batteries.


3. The conclusion


In summary, new energy vehicles will inevitably become one of the main means of transportation in the future. In order to promote the research and development of new energy vehicles as soon as possible, relevant national ministries, research institutes, and production enterprises should work together to integrate existing scientific and technological resources and build a sound The basic platform for technological innovation, the construction of a number of internationally advanced engineering platforms, the development of a number of enterprise-led, scientific research institutions and institutions of higher learning to actively participate in the industrial technology innovation alliance, focusing on the construction of power battery industry gathering areas. Actively promote the large-scale production of lithium-ion power batteries, accelerate the cultivation and development of a number of power battery manufacturers with continuous innovation capabilities, and form leading enterprises with production and sales scales exceeding 10 billion watt-hours, with key materials research and development production capacity, and in the positive and negative poles. Key materials such as diaphragms and electrolytes form key production enterprises, improve the overall technical level of lithium-ion batteries, and promote the rapid development of new energy automobile industry.
