Basaltic underplating has deepened the CMB from 32 km to 42 km. The lower crust beneath Hannuoba consists mainly of two-pyroxene granulites, with minor felsic granulites, noritic granulites, spinel pyroxenites and spinel lherzolites.

该地温梯度线表明，华北克拉通北缘的岩石学壳幔边界很可能位于约42km处，与地震莫霍面近于一致。32-35km处的尖晶石二辉橄榄岩层可能反映了古岩石学壳幔边界的位置，玄武质底垫作用造成岩石学壳幔边界的深移。

The cathode is generally one of three materials: a layered oxide, such as lithium cobalt oxide, one based on a polyanion, such as lithium iron phosphate, or a spinel, such as lithium manganese oxide, although materials such as TiS2 were originally used.

阴极通常是以下三类材料：一种层氧化物，例如钴酸锂、一种阴离子聚合物，例如磷酸锂铁，或者是一种尖晶石，例如锰酸锂，象例如二硫化钛之类材料曾经是最初使用的材料。
