锂系热电池中电解质粘合剂MgO的优选
Choice of MgO powders for immobilizing electrolyte in lithium-thermal battery
摘要
Abstract
In order to find superior MgO powders for immobilizing electrolyte in lithium-thermal battery,the surface morphology and melting point of five commercial MgO powders and EB materials were characterized by scanning electron microscopy (SEM) and DSC,respectively.The immobilizing effect of MgO powder was evaluated by electrolyte leakage behavior of separator pellets.The experimental results indicate that when the content of EB material increases from 30％ to 60％,the electrolyte leakage content decreases from 109 to 27 mg/cm2,the 3# MgO powder with small particle size,better dispersive particles and large pore size is the most excellent binder for molten salts.The other MgO materials exhibit disordered surface morphologies,and the powder is poor dispersive particles with small pore size and poor immobilizing effect for electrolyte.The EB materials were used as separator in thermal batteries.The discharge tests of single cell were performed at constant current density of 0.2 A/cm2,and pulse current was delivered on the load to gain the polarization resistance of batteries.The discharge tests show that thermal battery with 3# MgO powder as binder has the highest capacity and lowest polarization resistance.关键词
