Military battery | What special requirements do military lithium batteries have on materials?
The continuous progress and maturity of lithium battery processing technology has also reduced the processing cost of lithium batteries. Lithium batteries can be widely used in power vehicles, energy storage equipment, military equipment, medical machinery and other fields. The advancement of lithium battery technology will not only accelerate the development of digital products, but also promote the development of defense industry and telecommunication technology.
The application of military lithium batteries covers land (individual soldier systems, army combat vehicles, military communication equipment), sea (submarines, underwater robots), air (unmanned reconnaissance aircraft), sky (satellites, spacecraft) and many other arms. The energy density, endurance time, volume weight, etc. of the power supply of military equipment are important factors affecting the combat capability of the troops. Military lithium batteries have high energy density, small size, light weight, long cycle life, low self-discharge rate, no memory effect, and low temperature. It has many advantages such as good performance, reliable use, low maintenance cost, fast charging, long discharge time under high current, etc. It is the first choice for military equipment power supply.
The design requirements of military lithium batteries are much stricter than those of civilian batteries. The specific requirements for military lithium batteries are as follows: High safety: During high-intensity shocks and blows, the battery must be safe and will not cause personal injury or death. High reliability: It is necessary to ensure that the lithium battery is effective and reliable in use. High environmental adaptability: It is necessary to ensure that it can be used normally under different climatic conditions, high-intensity electromagnetic environment, high/low pressure environment, high radioactive radiation environment and high salt environment.
Expanding the application of special equipment for lithium batteries has become a new growth point. The application of lithium-ion batteries in various fields of special equipment has gradually spread. Among them, in the fields of communication equipment, portable equipment, and small unmanned aerial vehicles, lithium-ion batteries have become the absolutely dominant energy storage equipment; at the same time, lithium-ion batteries have gradually Enter the field of underwater equipment, vehicle equipment and other fields. The application of battery energy storage systems represented by lithium-ion batteries in special fields can increase the concealment of equipment, improve equipment reliability, increase endurance and sailing time, and reduce logistics requirements related to fuel support.
For small lithium batteries (such as mobile phone batteries), it requires positive and negative electrode active materials to have as high an electrochemical specific capacity as possible, so as to ensure a higher capacity of lithium batteries, so the choice of positive and negative electrode materials is mainly Consider the electrochemical specific capacity of the material.
For medium and large lithium batteries, it requires the positive and negative electrode active materials to have the highest possible electrochemical specific capacity. Under the working principle of lithium battery, it must have excellent reliability and safety. Therefore, in the selection of positive and negative electrode materials, while considering the electrochemical specific capacity of the material, the main concern is the safety of the material.
