How extensive will the "big boom" of lithium batteries in electric cars be in the future?

When it comes to the lifeblood of new energy vehicles, it is the battery.

As the power source of electric vehicle, battery plays an important role. In essence, it is a device that can convert stored chemical energy into electrical energy. In the current market, lithium battery is widely used, such as BYD, BAIC new energy, CHERY new energy and most of the vehicles have adopted the technology form.

In addition to the current state of development, lithium battery technology in the past decade in a steady development, but the future will be overturned, also unknown!

Price will become the market - oriented, lithium battery can still "hot"?

The development of domestic new energy vehicles has exceeded ten years. A few years ago, driven by the national new energy industrial policy, a frenzy of manufacturing lithium batteries was set off across the country. At one time, there were more than 400 lithium battery cell and pack assembly companies (including lithium battery for new energy vehicles), among which there were 200-300 lithium battery companies involved in electric vehicles. However, the core materials, such as anode materials, electrolytes and aluminum plastic film for flexible packaging cells, are heavily dependent on imports, resulting in the high cost of manufacturing lithium batteries. The price of lithium batteries with the same capacity is more than three times that of lead-acid batteries, leading to a difficult market promotion.

   But in recent years, the domestic lithium battery material technology continues to break through, most of the core materials basically realized the localization rate. At present, the 48v11Ah (18650 cylindrical steel shell, each cell is 2200 mA, and 65 cells are connected in series and parallel) of lithium battery, including the charger, is in a group, and the price is less than 500 yuan. Compared with lead-acid battery, it has the advantage of cost performance. That's about a third of what lithium batteries cost when they first hit the market. This shows that lithium batteries gradually replace lead-acid batteries is not empty talk.

With advances in solar technology, how long can lithium batteries survive?

For future development, lithium battery technology still faces challenges. Although thermal energy has reduced costs and improved thermal energy storage, in the long run, it will eventually lose the impact of solar energy technology. At present, many countries have begun to formulate long-term solar energy development plan, such as America's national PV plan, Japan's sunlight without electricity and China's eastern provinces countryside electrification project, from mono crystal silicon solar energy application technology and advanced devices, thin film PV technology, PVMAT, PV modules and PV system performance and engineering, application and market development, and other fields gradually.

For the current solar cell technology, divided into mono crystal silicon solar cells, poly crystal silicon thin film solar cells and amorphous silicon thin film solar cells, three current mono crystal silicon solar technology is the most mature, but due to the cost of single crystal silicon prices high, will gradually be replaced by poly crystal silicon thin film solar cells, but the most promising or amorphous silicon thin film solar cells; Second, NANO crystal solar cells are gradually coming into people's vision. With extremely low production cost and simple process, NANO crystal solar cells can harvest stable performance. The production cost is only 1/5 ~ 1/10 of that of silicon solar cells.

Conclusion: battery is the core component of electric vehicle, which directly determines the most critical range for electric vehicle. At present, research on battery for electric vehicles is still focused on lithium battery, followed by lead-acid battery, nickel-metal battery and sodium battery. Japan and the United States lead the world in the number of patent applications for battery and its management system for electric vehicles. With the gradual warming of new energy, the investment in the battery industry is also increasing, in the next few years, the battery technology will usher in rapid development.
