As we all know, the new market demand for lithium-ion batteries is forming very fast. Lithium-ion batteries currently come in three chunks. One is consumer electronics. Now people on mobile devices, smart phones, laptops, the vast majority of lithium-ion batteries have been used, this market capacity can be basically calculated as a unit of billions. The second is the rising demand for electric vehicles, whether pure electric vehicles or plug-in hybrid electric vehicles, the current demand has gradually formed. Third, lithium will be used in the field of energy storage. Its market capacity will be larger than that of electric cars, and it can even be measured in trillions of dollars of output value.
The demand of electric vehicles and energy storage market has created a new market space for lithium-ion batteries. At present, a group of enterprises with technical basis and production capacity are growing very fast, and the technological progress of power batteries is also very rapid.
Lithium battery is one of the battery types commonly used in electric vehicles, and is being used by more and more new energy vehicles. Even though lithium-ion batteries are nowhere near as energy-dense as gasoline, other battery technologies have struggled to match them. 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 improved. At present, lithium batteries equipped with mainstream electric vehicles mainly include lithium iron phosphate batteries and ternary lithium batteries. Compared with lithium iron phosphate batteries, ternary lithium batteries are much higher in weight and energy density. In addition, ternary lithium batteries have much higher low temperature resistance in winter than lithium iron phosphate batteries. That means a ternary lithium battery of the same weight can have a longer range than a lithium iron phosphate battery. As the energy density of lithium iron phosphate battery has little room to improve, and ternary lithium battery still has room for development, ternary lithium battery will become the technology 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 fairly mature technologies to match the rapid development of these two industries. For now, lithium-ion power batteries are the best option. The broad market demand is also attracting a lot of research and development and manufacturing investment in this industry, which promotes the rapid development of lithium-ion battery technology, so this industry has been developing very fast. When it comes to power batteries, they are actually very important in terms of technology. 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.
