The reason for the development of lithium battery pack technology -Lithium - Ion Battery Equipment
In recent years, researchers have worked hard to improve the energy density, value, safety, environmental impact, and trial life of lithium -ion battery packets, and design new types of batteries. So, when can battery technology have revolutionary breakthroughs?
1. The development of traditional lithium -ion battery packs is slow, and the space for further optimization is limited
Consumer electronics, automobiles and power grid storage are currently three industries in battery applications. The editor referred to these three industries as the three major areas of people connected to the battery. Each field has different requirements for batteries, so the battery used may be very different.
The mobile phone in your pocket must be strong and safe battery, and the weight and cost need to be considered too much.
As far as the car battery industry is concerned, there are many batteries, so cost and weight and cycle service life (if New Tesla changes new batteries every two years, you will crazy) become very important.
The batteries used to store houses and grids are not high in weight or size.
Almost every part of the electronics industry has to be battery, which is also limited by the power output and energy life of the battery. The development or progress of the battery is much slower than other fields. This is the limitations of the battery itself. You cannot expect batteries that can supply mobile phones for one or one month. Because the maximum energy stored in the battery is determined by the inherent elements.
Because lithium ion is the lightest alkaline metal element and has the characteristics of smaller, lighter, and energy density, it quickly replaces nickel batteries. Among the constituent substances of lithium ion battery packets, there are other metal and non -metal materials such as iron phosphate, manganese, graphite, titanate, etc., but the element of lithium ion is embedded and removed in the positive and negative electrodes before it can be achieved before it can be achieved before it can be realized. The transformation of electrical energy and chemical energy finally completed the charge and discharge process.
However, the technological progress of lithium -ion battery packets has developed slowly. At present, lithium -ion batteries are much higher than lead -acid and nickel -metal hydride batteries in terms of energy density, high and low temperature characteristics, and multiplier performance, but it is still difficult to meet the needs of rapidly rising electronic products and electric vehicles. Now the traditional lithium -ion battery technology is close to the bottleneck, and the space for further optimization is limited.
2. Scientists are committed to developing new lithium -ion batteries
At present, scientists are committed to developing new batteries with stronger energy storage and longer life, especially developing more suitable batteries in different fields, because no battery can apply all fields.
1. Not long ago, Chinese scientists have developed a lithium -ion battery that can be used at minus 70 degrees Celsius. It is expected to be used in the extremely cold area of the earth and even outer space in the future. According to researchers, the cost of materials used in this new battery is not high and environmentally friendly. However, it remains to be commercialized. The important problem is that its energy density is too low, and it is not comparable to the traditional lithium -ion battery bag.(Lithium - Ion Battery Equipment)
2. In the automotive industry, the battery finally determines the life of the car, and also determines the fear and anxiety of electric vehicles. To solve this problem, engineers and scientists are trying to fill more voltage capacity into the battery. At present, a large number of studies are committed to finding new materials and chemicals to assist or replace the lithium ion pattern or other parts of the battery.
For example, some innovative practices can replace the traditional graphite anode lattice to silicon, which will have more than 10 times lithium ions, but silicon will swell when absorbing lithium ion The lattice acts as anode, but it may occur in a short circuit when charging. And this is the problem that the boss has been headache for the headache of battery manufacturers in the 2030 years since the launch of lithium -ion batteries.
3. Care the battery's cardiac electrode/electrolyte interface. Among all environmental factors, temperatures have the greatest impact on the battery charging and discharge performance. Xia Yongyao, a professor at the Department of Chemistry and New Energy Research Institute of Fudan University in my country, led the team to develop a new cold -resistant battery. The ethyl acetate with low coagulation point and conducted electricity under extreme low temperature conditions is used as an electrolyte. The cathode and anode.
