이차전지는 형태에 따라 원통형, 각형 및 파우치 타입으로 구분할 수 있으며,최근 안정성과 제품 응용력이 우수한 파우치 타입의 이차전지가 크게 주목 받고 있다.Secondary batteries can be classified into cylindrical, prismatic, and pouch types depending on the shape. Recently, the pouch-type secondary battery, which has excellent stability and product application power, has attracted much attention.

리튬 폴리머 이차전지는 외장재가 캔(Can) 타입이 아닌 알루미늄 파우치를 적용한 전지로서 소량의 전해액 또는 겔(Gel) 타입의 전해액을 사용하기 때문에 전해액 누액의 염려가 거의 없고, 안정성 확보, 형상 다변화, 박형화 및 경량화의 장점을 가지고 있다.The lithium polymer secondary battery is a battery that uses an aluminum pouch, not a can type, as the exterior material is a small amount of electrolyte or gel type, so there is little concern about electrolyte leakage, securing stability, diversifying shape, and thinning And light weight.

[실험예][Experimental Example]

합지 조건에 따른 파우치 필름의 초기접착력 및 내전해액성 등의 물성 변화를 확인하기 위하여, 나일론/알루미늄 필름과 CPP의 합지 속도(6.0, 18.0 M/min), 온도(50 - 130℃) 및 압력(∼80 kgf/㎠)의 조건으로 실험하였다. In order to confirm changes in physical properties such as initial adhesive strength and electrolyte resistance of the pouch film according to the lamination conditions, the lamination speed of the nylon / aluminum film and CPP (6.0, 18.0 M / min), temperature (50-130 ° C) and pressure ( ∼80 kgf / cm 2).

각각의 합지 조건은 다음과같다.The conditions of each lamination are as follows.

나일론/알루미늄 필름과 CPP의 합지 조건으로 50 ∼ 130℃ 의 온도 범위와 80 kgf/㎠의 고정 압력에서 6.0 m/min과 18.0 m/min의 속도 조건으로 합지하였다. The lamination conditions of the nylon / aluminum film and CPP were combined at a temperature range of 50 to 130 ° C. and a fixed pressure of 80 kgf / cm 2 at a speed condition of 6.0 m / min and 18.0 m / min.

분석방법으로는 알루미늄과 CPP 필름간 접착강도 확인을 위하여 동일시마즈사의 인장강도 시험기(Autograph AGS-X 500N)를 사용하였으며, 180° Peel Test 방법으로 300 mm/min의 속도조건으로 측정하였다. As an analysis method, a tensile strength tester (Autograph AGS-X 500N) manufactured by Dongil Shimadzu was used to check the adhesive strength between the aluminum and CPP films, and it was measured at a speed condition of 300 mm / min by the 180 ° Peel Test method.

파우치 필름의 내화학성 실험으로는 활성도가 큰 전해액의 영향에 따른 파우치 필름의 접착강도 변화를 확인하기 위하여 수행하며 작동되는 전지환경에서의 발생되는 열은 전해액의 활성을 크게 하여 필름의 접착력을 떨어뜨린다. The chemical resistance test of the pouch film is performed to confirm the change in the adhesion strength of the pouch film according to the influence of the electrolyte having high activity. Heat generated in the operating battery environment increases the activity of the electrolyte to degrade the adhesion of the film. .

그러므로 내화학성 실험은 통상적으로 85℃의 높은 온도에서 수행된다. 전지에 사용되는 전해액(EC : DEC : DMC = 1 : 1 : 1, LiPF6 1M)에 파우치 필름을 함침하여 85℃ 조건에서 7일간의 시간 경과에 따른 알루미늄 필름과 CPP 필름의 층간 접착강도 변화를 확인하였다Therefore, the chemical resistance experiment is usually performed at a high temperature of 85 ° C. Impregnation of the pouch film in the electrolyte used in the battery (EC: DEC: DMC = 1: 1: 1, LiPF6 1M) confirms the change in the adhesion strength between the aluminum film and the CPP film over time at 85 ° C for 7 days.

Under the condition of lamination speed of 18.0 m / min (red line graph), the adhesive strength of 1000 gf / 15 mm or higher was shown at a higher temperature of 110 ° C., and it was confirmed that the adhesive strength was high at a relatively low speed.

도 6은 나일론/알루미늄과 CPP 필름이 110℃의 온도와 80kgf/cm2의 압력 조건으로 고정하고, 6.0m/min과 18.0m/min의 합지속도로 제작한 파우치 필름의 내전해액성 결과를 보여준다. 6.0m/min과 18.0m/min 시료의 초기접착강도는 각각 1200 gf/15mm와 1050gf/15mm의 강도를 나타냈다. 85℃ 오븐에서 전해액에 함침 후 7일간의 경과 시간동안의 알루미늄과 CPP 필름 간 접착강도를 확인한 결과 두 시료 모두 시간이 경과하면서 접착강도는 일정하게 감소하는 경향을 보였으며 7일 경과 후 6.0m/min과 18.0m/min 시료의 내전해액은 각각 600과 500 gf/15mm으로 상대적으로 낮은 속도에서 합지한 파우치 필름의 접착 강도가 다소 높은 결과를 보여주었다. 1일 경과에서는 18.0m/min조건의 시료가 다소 높은 내전해액성을 보였다.6 is a nylon / aluminum and CPP film is fixed at a temperature of 110 ℃ and a pressure condition of 80kgf / cm2, shows the results of the electrolyte resistance of the pouch film produced at a lamination speed of 6.0m / min and 18.0m / min. The initial adhesive strengths of the 6.0 m / min and 18.0 m / min samples showed strengths of 1200 gf / 15 mm and 1050 gf / 15 mm, respectively. As a result of checking the adhesion strength between the aluminum and CPP films for 7 days after immersion in the electrolyte in an oven at 85 ° C, both samples showed a tendency to decrease the adhesion strength over time and 6.0m / after 7 days. The min and 18.0m / min samples showed 600 and 500 gf / 15mm, respectively, and the adhesive strength of the laminated pouch film was relatively high at relatively low speeds. After 1 day, the sample under the condition of 18.0 m / min showed somewhat higher electrolyte resistance.
