NIMS Nanoporöse amorphe Silizium-Dünnschicht-Anode - Lithium-Ionen-Batterieausrüstung
The NIMS team combined nanoporous amorphous silicon films with inorganic solid electrolytes to address the problem of capacity fading. The nanoporous structure can accommodate the volume change of silicon, thereby limiting the mechanical fracture and pulverization of the anode.
Unlike liquid electrolytes, solid electrolytes do not decompose because of their wide electrochemical stability window. It has been proved by experiments that the capacity of silicon material is high, and even if it is charged and discharged 100 times, the attenuation of the capacity is also small.(Lithium - Ion Battery Equipment)
