Sigma-Aldrich 1 M Biphenyl in THF，制备用于无序碳、SiO、Sn、Sb、P和S电极的预锂化/预分散试剂的前体溶液

产品概述

制备用于无序碳、SiO、Sn、Sb、P和S电极的预锂化/预分散试剂的前体溶液

应用领域

This product is biphenyl (Bp) solution in anhydrous THF (1 mol/L) is a precursor reagent that could be easily handled to prepare prelithiation or presodiation reagent. By direct reaction of Li metal, it forms a strong reducing reagent of Li-Bp. The resulting Li-Bp/THF reagent has the redox potential of 0.41 V vs. Li/Li⁺, which is applicable to prelithiate most of the active materials for Li ion batteries, such as Sn, Sb, P, S, SiO and other metal oxide. On the other hand, a presodiation reagent can be prepared by reacting Bp/THF solution with Na metal. Na-Bp/THF reagent can be used to presodiate hard carbon, a promising anode material in Na ion batteries.PMID 30777747

制备/使用说明

建议用途：为了制备1M Li-Bp/THF试剂，将> 0.07g的Li金属加入到每10ml的1M BP/THF溶液中。为了制备1M Na-Bp/THF试剂，将> 0.23 g Na金属加入到每10 ml 1 M BP/THF溶液中。步骤2电极的浸渍/预辐射对于每cm 2具有1 - 3 mg活性材料的1 cm直径电极，（10 - 60 min，时间因材料而异）将电极置于0.5 - 1 mL预锂化/预辐射试剂中，弃去溶液，然后用THF清洗电极两次。长时间的预锂化/预辐射可能会导致电极结构变形，导致放电/充电容量下降。
