    摘要: An electrode for electrical power accumulators, in particular lithium-ion batteries, has a structured surface. In one embodiment, the cathode electrode is implemented as structured, this structuring occurring at the same time as the production in a laminator. Capillaries are produced. Upon filling of the cell, these capillaries conduct the electrolytes, because of their capillary action, into the middle of the coiled cathode electrode, i.e., into the middle of the cell. It is thus possible to fill the lithium-ion cell in a single step.
