Abstract
The effects of different lithium salt contents on the crystallinity and conductivity of solid polymer electrolytes PEO-LiClO4 were analyzed by DSC thermal analysis method and AC impedance method. Furthermore, the variation of bonding current and time during the bonding process between metal aluminum and PEO-LiClO4 with different LiClO4 content was studied under different bonding voltages. The results show that with the addition of lithium salt and increasing its content, it can effectively hinder the crystallization of PEO and improve its room temperature conductivity. The more the lithium salt content, the higher the bonding voltage, the larger the peak current generated during the bonding process, the thicker the intermediate transition layer, and the higher the bonding strength.
