Abstract:
PURPOSE: A battery module is provided to stably secure electric connection states of respective unit cells, to be easily manufactured and assembled, and to provide excellent durability. CONSTITUTION: A battery module structure comprise: unit cells(3) in which each battery tap of a positive electrode and a negative electrode is formed on the edge in order to discharge electricity; many receptacles(5) integrated to each battery tap of the unit cells; and a bus bar(7) electrically connecting between the receptacles. The receptacles comprises an insert groove opened along a direction vertical veto a plane formed by the unit cells in order to form an electric connection state by an insertion part of the bus bar inserted along a direction parallel with the plane formed by the unit cells.

PURPOSE: A process for manufacturing a negative electrode material for a lithium secondary battery is provided to manufacture various phosphate-based negative electrode materials without thermal process of high temperature and to reduce the time required for whole process. CONSTITUTION: A process for manufacturing a negative electrode material for a lithium secondary battery includes the steps of: mixing transition metal compounds dissolved in distilled water with poly acid phosphate-based compounds to prepare a mixed solution; stirring the mixed solution to prepare a precipitate by a co-precipitation method; drying the precipitate to a temperature of 50-80 °C; and heat-treating the dried material at a temperature of 300-500 °C.
Abstract:
PURPOSE: A battery pack is provided to automatically secure a cooling channel by windows and groove portions of a cell case without the interval between cell assemblies when modularize the cell assemblies through lamination. CONSTITUTION: A battery pack has laminated cell assemblies(100). In the cell assembly, a window(111a) is formed so that unit cells(120) are exposed at both sides of a cell case(110); a groove portion(111c) is formed at both ends of the cell case so that the window is communicated with the laminated cell assembly; and a cooling channel is formed between the window and the groove portion.
Abstract:
본 고안은 자동차의 인 사이드 리어 뷰 미러 어셈블리에 관한 것으로서, 특히 스위치 조작에 의해 리어 뷰 미러의 각도를 용이하게 조절할 수 있도록 함으로써 안전사고의 발생을 미연에 방지할 수 있는 자동차의 인 사이드 리어 뷰 미러 어셈블리를 제공한다. 본 고안은, 리어 뷰 미러(40)의 하측면을 커버(30)의 내측 하면에 회동 가능하게 힌지 결합시키고, 리어 뷰 미러(40)의 중심 일측면과 대응되는 커버(40)의 내측 중심면에는 전류의 공급에 의해 인력을 발생시키는 전자석(M)과 철편(41)을 각각 부착 고정하며, 리어 뷰 미러(40)의 상면과 커버(30)의 상면 사이에는 리어 뷰 미러(40)의 초기 위치 복귀를 위한 리턴 스프링(S)을 개재하여 구성된다.
