초록 ▼

An electrochemical cell may have a PVDF microporous membrane that may be adhesively bonded to electrodes. The adhesive may be a mixture of a solvent and non-solvent that may cause the PVDF membrane to become tacky and adhere to an electrode without collapsing. An adhesively bonded cell may be constructed using multiple layers of adhesively bonded membranes and electrodes. In some embodiments, the adhesive solution may be used as a sizing to prepare electrodes for bonding.

대표청구항 ▼

1. An adhesive for bonding a microporous PVDF membrane, said adhesive comprising: PVDF polymer dissolved in a solvent, said solvent being acetone and having a first surface energy; anda non-solvent comprising a first liquid non-solvent and a second liquid non-solvent;wherein the first liquid non-solvent having a second surface energy that is lower than said first surface energy, and the second liquid non-solvent having a surface energy that is different from said second surface energy, andwherein said solvent being included in an amount of greater than or equal to about 78.875 weight percent, said first liquid non-solvent having a second surface energy that is lower than said first surface energy being included in an amount of greater than or equal to about 12.5 weight percent, said second liquid non-solvent having a surface energy that is different from said second surface energy being included in an amount of greater than or equal to about 0.875 weight percent, and said PVDF polymer being included in an amount of at least 2 weight percent, based on the total content of the adhesive. 2. The adhesive of claim 1, wherein said second liquid non-solvent is water. 3. The adhesive of claim 1, wherein said first liquid non-solvent is isopropanol. 4. The adhesive of claim 1, wherein the PVDF polymer being included in an amount of up to 10 weight percent based on the total content of the adhesive. 5. The adhesive of claim 1, wherein the PVDF polymer being included in an amount of up to 6 weight percent based on the total content of the adhesive.
