Abstract: We studied the possibility of using composite films representing amorphous silicon reinforced with crystalline inclusions of copper silicide as an anode material for lithium-ion batteries with liquid electrolyte. The films were made by layer-by-layer magnetron sputtering of amorphous silicon and copper, followed by low-temperature (100–200$^\circ$C) annealing of the structure. The tests of the anodes revealed the effect of prolonged intense growth of their reversible capacity. To describe the effect, a phenomenological model based on the multidirectional migration of silicon and copper atoms in an inhomogeneous field of elastic mechanical stresses arising during electrode cycling is proposed.
Keywords: nanocomposite film, capacitive profile, vacancy voids, gradient of elastic stresses, atomic migration.
