The silicon-based electrode forms an interface with a pair of layers that is 1. A thin semi-dielectric layer made of a lithium (Li) compound, such as lithium fluoride LiF, disposed on and adhered to the electrode surface of the silicon-based electrode, and 2. A molten ionic conductive layer containing a lithium salt (lithium salt layer) disposed on the semi-dielectric layer. One or more device layers may be disposed on the layer pair to fabricate a device, such as an energy storage device, such as a battery. The interface has low resistivity, which reduces energy loss and heat generated by the device. 硅基电极与层对形成界面，所述层对为：1.由锂(Li)化合物，例如氟化锂LiF，制成的薄的半介电层，其设置在硅基电极的电极表面上并与其粘附，和2.含锂盐的熔融离子导电层(锂盐层)，其设置在半介电层上。一个或多个器件层可以设置在层对上以制造诸如能量存储装置的装置，如电池。该界面具有低电阻率，其减少了能量损失和器件产生的热量。
