What material is the shell feature of lithium battery products made of?

It is mainly different from the starting battery used for starting automobile engines. Lead-acid batteries with sealed valve ports, open-tube lead-acid batteries and lithium ferrous phosphate batteries are mostly used. The lithium battery case is a kind of protective case for users to protect lithium-ion batteries, which can play a protective role. The main purpose of the lithium battery case is to protect the internal materials of the battery and increase the protective layer with the increase of the strength of the case. Otherwise, it is not only unsightly, but also low in strength. Generally, there are stainless steel, aluminum and aluminum-plastic films. Of course, inert materials that can resist HF acid corrosion and do not participate in electrode reaction can be used, as long as there is good insulation between the positive and negative electrodes. What material is used depends on the application field and environment of the battery. We can customize it according to the needs of users. The shell of lithium battery is made of high quality aluminum. After extrusion, the product has good brightness and accurate size. Products have various specifications and models, and their specifications can also be customized according to customer needs. Suitable for all kinds of aluminum capacitors and other related electronic products. It has the characteristics of explosion protection, high temperature resistance and corrosion resistance. Good surface treatment performance, stable chemical properties, non-magnetism, and can be recycled.

Lithium battery shell characteristics, atomic number 3, atomic weight 6.94 1, is the lightest alkali metal element. In order to improve safety and voltage, scientists invented materials such as graphite and lithium cobaltate to store lithium atoms. The molecular structure of these materials forms a nano-scale fine storage lattice, which can be used to store lithium atoms. In this way, even if the battery case breaks and oxygen enters, oxygen molecules are too big to enter these tiny batteries, so that lithium atoms will not contact with oxygen and avoid explosion. This principle of lithium-ion battery enables people to realize its high capacity density and safety at the same time. When the lithium-ion battery is charged, the lithium atoms in the anode will lose electrons and be oxidized into lithium ions. Lithium ions swim to the negative electrode through the electrolyte, enter the battery of the negative electrode, obtain an electron, and are reduced to lithium atoms. When discharging, the whole process is the opposite. In order to prevent short circuit caused by direct contact between the positive and negative electrodes of the battery, separator paper with many fine holes will be added to the battery to prevent short circuit. Good separator paper can also automatically close the air holes when the battery temperature is too high, so that lithium ions can't pass through, so as to waste martial arts and prevent danger.
