Descrição

Descrição geral

Aluminum sulfate is a white crystalline solid that is highly soluble in water. It is thermally stable and has the ability to act as a coagulant and flocculant. It is widely used in the field of solar cells, water treatment and batteries.

Aplicação

Aluminum sulfate can be used:

• As a surface modification agent/co-adsorbent for dye sensitizers in solar cell. It improves the surface of photoelectrode and purify dye solution through flocculation.
• As an electrolyte additive for lead-acid batteries to effectively inhibit the passivation of electrodes. It helps to slow down cathode sulfation and improve the reversibility of the electrode reaction.
• To prepare aqueous electrolyte for high energy aluminum electrochemical cells. It helps to form artificial solid electrolyte interphase to attain high specific energy.
