    We propose aluminum foil (positive electrode current collector), copper foil (negative electrode current collector), separator, and insulation spacer as materials for lithium ion secondary batteries.

    Inquiries about the Products
    Product Name
    Aluminum foil (positive electrode current collector)

    Details

    		 As a positive electrode current collector for lithium ion secondary batteries, high strength and high purity are required, even though they are thin foils.
    Product Name
    Copper foil (negative electrode current collector)

    Details

    		 As a negative electrode current collector for lithium-ion rechargeable batteries, it is required to have a high-purity of more than 3N, an ultimate thin thickness of several micrometers, and high strength.
    Product Name
    Separator

    Details

    		 It isolates the positive and negative electrodes of the lithium-ion secondary battery, offering excellent heat-resistant dimensional stability, and prevents thermal runaway due to internal short-circuiting.
    Product Name
    Insulating spacer (under development)

    Details

    		 This spacer is used to suppress heat transfer to adjacent cells in the event of abnormal heat generation in LIB cells.
