What is the defect in the metal monument of lithium batteries?

Lithium battery metal negative electrode materials mainly include metal monomi and intermetallic compounds. This type of material has an ultra-high anterior element, but as a lithium battery negative material, a large volume effect is generated, i.e., when a large amount of lithium is stored, the volume can be expanded to the original several times, which greatly causes electrode powder. The circulating performance of the material is poor, such as the formation of Li22Sn to form a high-rich lithium alloy with lithium, the theoretical capacity is as high as 994mA.h / g; the amount of atoms of aluminum is small, the weight is light, although the amount of lithium per mole of aluminum (2.5mol It is less than the metal SN of the lithium amount (4.4 mol), but its density is small, theoretical weight is as high as 2234 nsa ¡¤ h / g, but the metal moniral does not have the feasibility of directly use as a lithium battery negative electrode material. The intermetallic compound is generally a tin-based nanopathic material, and the selection principle is mostly the 'active material / non-active material "type, and some' active material / active materials" type. Since there is a strong mutual interregion between alloy groups, reasonable serequentity components can effectively inhibit the "volume effect" of nano metal mononis, improve the cycle properties of electrode materials, such as Ni3SN4 alloy, SN-Ni alloy, S N- SB alloy, SN-Cu-B alloy, Ni3SN2 alloy, Al-Cu alloy, Al-Mn alloy, etc. have high initial phosphithium capacity, but the irreversible capacity loss of the first charge and discharge process is too high, and the capacity is faster. Actual applications are still subject to many restrictions Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
