Lithium ion battery is widely used in various fields

Release Time: 2022-03-25
As we all know, new market demand for lithium ion batteries is forming very quickly. Lithium-ion batteries are currently divided into three blocks. The first is consumer electronics. Now most of us have used lithium ion batteries in mobile devices, smart phones and laptops. The market capacity can be calculated in billions of dollars. The second is the emerging demand for electric vehicles, whether pure electric vehicles or plug-in hybrid vehicles, which is gradually forming. Third, remind colleagues to pay attention to is, in the future lithium electricity used in the field of energy storage. Its market capacity will be wider than electric cars, and even such an output value can be used to measure its market.

The demand of electric vehicle and energy storage market has formed a new market space for lithium ion battery. At present, a number of enterprises with technological foundation and production capacity are growing very fast, and the technological progress of power battery is also very fast.

Lithium battery is one of the commonly used batteries for electric vehicles and is being used by more and more new energy vehicles. Although lithium-ion batteries are nowhere near as energy-dense as gasoline, other battery technologies have struggled to match lithium-ion batteries. Lithium-ion batteries cannot be replaced by other batteries in terms of energy density and service life. From lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries, the energy density has been constantly increasing. At present, lithium batteries equipped with mainstream electric vehicles mainly include lithium iron phosphate batteries and lithium ternary batteries. Compared with lithium iron phosphate batteries, ternary lithium batteries are much higher in weight and energy density. In addition, the low temperature resistance of ternary lithium batteries in winter is much higher than that of lithium iron phosphate batteries. That means a ternary lithium battery of the same weight has a longer range than a lithium iron phosphate battery. As the energy density of lithium iron phosphate batteries has little room to improve, while ternary lithium batteries still have room for development, ternary lithium batteries will become the technological trend of electric vehicles in the future.

At present, the requirements of electric vehicles and energy storage applications require the industrialization of products with safety, high energy density, long life, low cost and relatively mature technology to match the rapid development of these two industries. For now, lithium-ion batteries are a good choice. The broad market demand is also attracting a lot of RESEARCH and development and manufacturing into this industry, which promotes the rapid development of lithium ion battery technology, so the industry has developed very fast recently. When it comes to power batteries, they are technically very important. Power batteries pursue five aspects of performance, safety is placed in the first place, the other two pursuit, one is energy density, one is power density, and then very important is the service life.
