Lead with calcium-based aluminum alloy1) Features:
A, the internal resistance is small, the resistivity is about 22 ¡Á 10-6? ¡¤ cm, close to pure lead;
b, the hydrogen is high, the decomposition voltage of water is higher than the battery of the lead antimony alloy, about 200mV ~ 250mV, so the loss of water is less maintenance;
c, calcium is negative potential, the calcium in the positive electrode does not transfer to the negative electrode, so the self-discharge is not accelerated.
2) Join the role of tin:
a, improve the grid and the active material interface, improve the charge acceptance capability of the electrode:
b, increase the mechanical properties of the alloy;
c, reduce polarization and corrosion, improve battery deep discharge capabilities
d, improve the flow performance of the alloy.
3) The role of adding aluminum:
Forming a thin film to prevent the loss of calcium in the molten calcium alloy. When there is aluminum, the calcium content can be no change in 36 hour 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
