연축전지 전극의 제조방법{Manufacturing method of electrode for lead storage battery}Manufacturing method of lead-acid battery electrode {Manufacturing method of electrode for lead storage battery}

본 발명은 연축전지의 전극 제조방법에 관한 것으로, 더욱 상세하게는 미크론 사이즈의 유기합성 극세사를 활물질에 첨가하여 전극을 제조하는 전극 제조방법에 관한 것이다The present invention relates to a method for producing an electrode of a lead-acid battery, and more particularly to an electrode manufacturing method for producing an electrode by adding a micron-size organic synthetic microfiber to an active material.

일반적으로, 연축전지의 전극은 활물질의 기계적 강도의 향상을 위하여 활물질 혼합시 유기합성 단섬유를 0.01 ~ 0.5 wgt %를 첨가하고 있다. 이때 첨가되는 유기합성 단섬유는 통상적으로 2~5 데니어의 섬도를 갖으며, 길이는 2 ~10밀리미터 정도이다. 유기합성 단섬유의 성분은 내산성 및 내산화성이 우수한 폴리프로필렌, 폴리에스테르, 모드아크릴 계열이 주종을 이루고 있다.In general, the electrode of the lead-acid battery is added 0.01 ~ 0.5 wgt% of the organic synthetic short fibers when the active material is mixed in order to improve the mechanical strength of the active material. At this time, the organic short fibers are added usually has a fineness of 2 ~ 5 denier, the length is about 2 ~ 10mm. The main components of the organic synthetic short fibers are polypropylene, polyester, and modacrylic series having excellent acid resistance and oxidation resistance.

근래의 연축전지 업계는 하이브리드 전기자동차용 고출력전지 개발에 힘쓰고 있으며, 이를 위해 활물질의 전기 및 이온전도도 향상을 위한 연구가 이루어지고 있다. In recent years, the lead-acid battery industry has been making efforts to develop high-output batteries for hybrid electric vehicles. To this end, research has been conducted to improve the electrical and ion conductivity of active materials.

전지의 고율 방전 특성 향상을 위해서 본 발명에서는, 활물질의 기계적 강도 보강을 위해 첨가하던 유기합성 단섬유를 미크론 사이즈의 유기합성 극세사로 대체하여, 활물질내에 분포한 유기합성 극세사 내부 및 표면의 모세관 현상을 통해 이온전도도를 증가시키는 방안을 검토하였다.In order to improve the high rate discharge characteristics of the battery, the present invention replaces the organic synthetic short fibers, which are added to reinforce the mechanical strength of the active material, with a micron-sized organic synthetic microfiber, thereby preventing the capillary phenomenon inside and the surface of the organic synthetic microfiber distributed in the active material. The method of increasing ion conductivity was examined.

유기합성 단 섬유는 전지 활물질의 기계적 강도를 증가시킬 목적으로, 활물질의 혼합시 첨가하게 된다. 재질은 전해액인 황산수용액에 대한 내산성을 고려하여, 폴리프로필렌이나 폴리에스테르 및 모드아크릴계열이 사용되고 있다. 사용되는 유기합성 단섬유는, 직접 방사법으로 제조되는 통상적인 합성 단 섬유의 사양인 2~5 데니어(직경은 약 12~20 마이크로미터)의 섬도를 갖으며, 길이는 2~10 밀리미터이다. 혼합시 투입되는 양은 0.01 ~ 0.5 wgt % 로, 이를 통해 최종적인 전극 활물질의 기계적 강도를 향상시켜 진동 및 충방전에 의한 활물질의 수축팽창으로 인해 활물질 구조가 파괴되는 현상을 억제하게 된다.Organic synthetic short fibers are added when the active material is mixed for the purpose of increasing the mechanical strength of the battery active material. As a material, in consideration of acid resistance to an aqueous solution of sulfuric acid, polypropylene, polyester, and modacrylic series are used. The organic synthetic short fibers used have a fineness of 2 to 5 deniers (about 12 to 20 micrometers in diameter), which is the specification of the conventional synthetic short fibers produced by direct spinning, and has a length of 2 to 10 millimeters. The amount added during mixing is 0.01 to 0.5 wgt%, thereby improving the mechanical strength of the final electrode active material, thereby suppressing the phenomenon of the active material structure being destroyed due to shrinkage expansion of the active material by vibration and charging and discharging.

극세사는 일반적인 섬유 제조방법인 직접 방사법의 한계인 0.5 ~ 1 데니어 사이의 섬유를 말하였으나, 해도형 초극세사와 분할형 초극세사가 개발됨에 따라 최소 0.001 데니어 까지 확장되었다. 이러한 극세사로 만든 직물 또는 부직포는 우수한 흡수성으로 인해 주방용품, 청소용품 목욕용품으로 사용되고 있으며, 기공이 미세해짐에 따라 고성능 방진 및 정수 필터 등으로 사용되고 있다.Microfiber refers to fibers between 0.5 and 1 denier, which is the limit of the direct spinning method, which is a general fiber manufacturing method, but expanded to at least 0.001 denier with the development of island-in-the-sea microfiber yarn and split microfiber yarn. Fabrics or non-woven fabrics made of such microfibers are used as kitchen utensils and cleaning utensils due to their excellent absorbency, and are used as high-performance dustproof and water filters as the pores become finer.

본 발명은, 투입되는 유기합성 단섬유(직경 10 ~ 50 마이크로미터)를 유기합성 극세사(직경 0.5 ~ 10 마이크로미터)로 대체함으로써, 단섬유의 표면적을 증가시키고, 섬유간 또는 섬유내부의 모세관 현상을 이용해 전해액의 확산을 용이하게 하여 이온전도도를 향상시키고 최종적으로 전지의 고율방전 특성을 향상시키기 위한 것이다.The present invention, by replacing the organic synthetic short fibers (diameter of 10 to 50 micrometers) into organic synthetic microfibers (0.5 to 10 micrometers in diameter), thereby increasing the surface area of the short fibers, the capillary phenomenon between the fibers or in the fiber It is intended to facilitate the diffusion of the electrolyte solution to improve the ion conductivity and finally to improve the high rate discharge characteristics of the battery.

따라서, 전해액인 황산에 대한 내산성, 주기적인 산화환원반응에 대한 화학적 안정성이 요구되는 재질을 갖고, 마이크로 미터 수준(1~10마이크로미터)의 굵기를 갖는 유기합성 초극세사를 선정, 전극 활물질에 첨가하여 고율방전특성에 대한 영향을 확인하였다. Therefore, an organic synthetic microfiber having a material requiring acid resistance to sulfuric acid as an electrolyte and chemical stability against periodic redox reactions and having a thickness of micrometer level (1 to 10 micrometers) is selected and added to the electrode active material. The effect on high rate discharge characteristics was confirmed.

또한 상기 극세사는 폴리에스테르 또는 폴리아미드 재질의 단일성분 이거나 두개이상의 복합성분으로 형성시킬 수 있으며, 복합방사 또는 고분자블렌드 방사법으로 제조되고, 0.001~0.5 데니어의 섬도를 갖는 해도형 또는 분할형 극세사로 길이 1~10mm인 스테이플 화이버로 구성시킬 수 있다.In addition, the microfiber may be formed of a single component or two or more composite components of polyester or polyamide, and may be formed by a composite spinning or polymer blend spinning method, and the island-in-the-sea or split microfiber having a fineness of 0.001 to 0.5 denier It can be composed of 1 ~ 10mm staple fiber.
