Summary:In a method for manufacturing a solid electrolyte membrane according to the present invention, it is possible to check the degree of filling a porous sheet with a solid electrolyte material in a visual manner, so that the raw material selection and manufacturing process of the solid electrolyte membrane can be optimized in a simple manner. In addition, the solid electrolyte membrane manufactured by applying the selected raw material and manufacturing process according to the verification method can reduce manufacturing cost while shape transformation becomes easy, thereby making processing easy when applied to batteries of various shapes. In addition, the solid electrolyte membrane according to the present invention is advantageous in improving the energy density of a battery by being formed in a thin film type while having excellent strength due to a composite of a porous polymer material such as a nonwoven fabric and a solid electrolyte material. 본 발명에 따른 고체 전해질막 제조 방법은 가시적인 방법으로 다공성 시트에 고체 전해질 재료가 충진된 정도를 확인할 수 있어 고체 전해질막의 원재료 선택 및 제조 공정을 간이한 방법으로 최적화할 수 있다. 또한, 이러한 확인 방법에 따라 선택된 원재료 및 제조 공정이 적용되어 제조된 고체 전해질막은 제조 비용을 절감할 수 있으며, 형태 변형이 용이하므로 다양한 모양의 전지에 적용하는 경우 가공이 용이하다. 또한, 본 발명에 따른 고체 전해질막은 부직포 등 다공질의 고분자 재료와 고체 전해질 재료가 복합화되어 있어 강도가 우수하면서도 박막형으로 제조될 수 있어 전지의 에너지 밀도 향상에 유리하다.
