What is important to mature battery technology at present? The development trend of power lithium battery technology -Lithium - Ion Battery Equipment
The support of electric vehicle research and development of electric vehicles will help the industrialization of electric vehicles. But in the end, the industrialization of electric vehicles must be preferred to solve the technical problems faced by electric vehicles. The battery is still the core technical problem. At present, countries around the world are seeking more advanced electric vehicle battery technology.
What is the current mature battery technology?
The development of battery technology has been developed for more than 300 years. Today, the battery technology has early lead -acid batteries to the current lithium ion battery technology, solid battery technology, nuclear battery technology, colloid battery technology, fuel power battery technology, etc. However, the current mature battery technology is important for lithium ion battery, lead -acid battery and collagen battery technology.
1. Battery technology: The battery technology was first invented. At present, there are two types of lead -acid batteries and colloid batteries. They are relatively stupid batteries. At present, most of the battery used in electric bicycles on the market is lead -acid battery.
2. Collagen battery technology: The raw material of colloidal battery is a white, non -fondable, non -toxic and non -polluting inorganic nano -powder material made by haloglobine. Large surface area, high surface activity, and high purity.
3. Fuel power battery technology: Fuel power batteries are an important oxidation reaction through oxygen or other oxidant, and the chemicals in fuel can be converted into electrical batteries. There are many types of fuel power batteries, but they all have the same working mode, which is composed of three adjacent regions: anode, electrolyte and cathode.
The development trend of power lithium battery technology
From the perspective of technical potential, the theoretical energy density of the lithium iron phosphate system is about 170Wh/kg, and the theoretical energy density of the ternary lithium-ion battery is 300-350Wh/kg. The energy density of energy density is relatively small. However, the energy density of the all -solid lithium -ion battery has great potential, which is more feasible in theory.
The technical improvement of power lithium batteries has a close relationship with the country's entire strategic orientation. The state takes pure electric drives as an important orientation. From this perspective, lithium -ion batteries should be developed in the direction of high -quality energy. Do some changes. At present, the state has made some layouts in solid -state batteries, and some universities and scientific research institutions have done a lot of research work and made relatively large progress.
The most important thing for power lithium batteries is these four application areas. The low -speed electric vehicles we usually see are very large application areas of power lithium batteries. Two aspects: one is technology; the other is the industrial level.
As the core competitiveness of the global automotive industry in the future, its technological progress has plays a key use for domestic electric vehicles. With the improvement of the concentration of the power lithium battery industry and the gradual maturity of the technical route, the future power lithium batteries will develop in a faster direction in a more secure, longer life, and charging speed.
At present, power lithium batteries are important in East Asia. From the perspective of global perspectives, Japanese technology is relatively leading. The progress of my country's battery technology is also huge. I believe that in the next three or five years, my country's battery technology will achieve the world. The first one.
