How is the future trend of electric vehicle lithium battery?

When it comes to the lifeblood of new energy vehicles, non-batteries are the only ones.

As a power source for electric vehicles, batteries play an important role. In essence, they are devices that convert stored chemical energy into electrical energy. In the current market, lithium batteries are widely used, and most of the vehicles such as BYD, Beiqi New Energy, and Chery New Energy have adopted this technology.

In addition to the current state of development, lithium battery technology has been developing steadily in the past decade, but whether it will be subverted in the future, it is not known!

The price will become the market-oriented, can lithium batteries still be "hot"?

The development of domestic new energy vehicles has exceeded ten years. In the past few years, under the impetus of the national new energy industry policy, there has been a wave of lithium batteries in all parts of the country. Lithium battery cells and package assembly companies once received more than 400 (including lithium batteries for new energy vehicles). Among them, there were 200-300 lithium battery companies involved in electric vehicles. However, the core materials such as the separator of the positive electrode material, the electrolyte and the aluminum plastic film for the flexible packaging battery are heavily dependent on imports, resulting in high cost of manufacturing lithium batteries, and the price of lithium batteries of the same capacity is the price of lead-acid batteries. More than three times, leading to difficult marketing.

In recent years, domestic lithium battery materials technology has continued to break through, and most of the core materials have basically achieved localization rate. At present, the lithium battery includes 48 v11ah (18650 cylindrical steel shell, each battery is 2200 mAh, 65 batteries in series and parallel) in groups, the price is less than 500 yuan, and the lead-acid battery More than, has a cost-effective advantage. This price is already about one-third of the lithium battery just introduced to the market. It can be seen that the lithium battery is gradually replacing the lead-acid battery is not an empty talk.

With the advancement of solar technology, how long can lithium batteries survive?

For the future development, lithium battery technology still has challenges. Although heat is reducing costs and improving thermal energy storage, from a long-term trend, it will eventually lose its impact on solar technology. At present, many countries have begun to develop medium- and long-term solar energy development plans, such as the US National Photovoltaic Program, Japan's Sunshine Program, and China's Western Province's No-Power Township Power-Up Program. Solar Applications Technology will be from monocrystalline silicon and advanced devices, thin films. Photovoltaic technology, PVMaT, photovoltaic components and system performance and engineering, photovoltaic applications and market development have gradually deepened.

For the current solar cell technology, it is divided into three types: monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells and amorphous silicon thin film solar cells. Currently, monocrystalline silicon solar technology is the most mature, but due to the high cost of single crystal silicon, Gradually replaced by polycrystalline silicon thin film solar cells, but the most promising is amorphous silicon thin film solar cells; second, nanocrystalline solar cells are gradually entering people's field of vision, with very low production costs and simple processes, but Stable performance is achieved at a cost of only 1/5 to 1/10 of the cost of silicon solar cells. Life expectancy can reach more than 20 years, which is one of the factors that make lithium batteries more challenging.

Summary: The battery is the core component of the electric car, which directly determines the most critical cruising range for electric vehicles. Currently, research on batteries for electric vehicles is still concentrated in lithium batteries, followed by lead-acid batteries, nickel-hydrogen batteries and sodium batteries. The number of patent applications for electric vehicles and their management systems in Japan and the United States ranks among the top two in the world. As new energy sources heat up, investment in the battery industry is also growing. In the next few years, battery technology will usher in rapid development.
