1235 H22 battery foil market has great potential

Date: 2019-08-21 17:33

1235 H22 battery foil, actually refers to the aluminum foil used for the positive electrode material of lithium ion battery, and aluminum foil for other purposes, such as aluminum plastic film for battery soft pack, ear, and modified carbon coated foil, electrolytic foil, etc. Covered. Therefore, simply calling it a battery foil is not accurate enough (the habit of the market is called).

 The 1235 H22 battery foil is used as a current collector:

 The 1235 H22 battery foil is used as a current collector for lithium-ion batteries. In general, the lithium ion battery industry uses rolled aluminum foil as a positive electrode current collector.Lithium batteries usually have both cylindrical and square shapes. The inside of the battery is spirally wound and is formed by a very fine and highly permeable polyethylene film insulation material between the positive and negative electrodes. The positive electrode includes a current collector composed of lithium cobaltate (or lithium nickel cobalt manganate, lithium manganate, lithium iron phosphate, etc.) and a 1235 H22 battery foil. The negative electrode is composed of a current collector composed of a graphitized carbon material and a copper foil. The battery is filled with an organic electrolyte solution, and a safety valve and PTC element (partially cylindrical) are also installed to protect the battery from damage during abnormal conditions and output short circuits.

1235 H22 battery foil

1235 H22 battery foil quality requirements:

   The surface of the first aluminum foil has uniform color, cleanness and flatness, and no obvious roll marks, pitting, pinholes and corrosion marks;The second aluminum foil surface has no rolling defects such as creases, spots, and bright lines;The third aluminum foil has no color difference on the surface;The fourth surface is oil-free, has no serious oil odor, and has no oil spots visible to the naked eye;Fifth surface tension, Dyne pen test is not less than 32 dyne;

1235 H22 battery foil used as a positive electrode:

      The latest research in the lithium-ion battery industry has found that the surface of the 1235 H22 battery foil used as a positive electrode current collector for a lithium ion rechargeable battery can be etched and roughened to improve the charge and discharge characteristics of the battery. The surface-roughened 1235 H22 battery foil has a significantly higher adhesion to the active material than the untreated aluminum foil. This plays an important role in the development of rechargeable batteries for hybrid vehicles and electric vehicles, as well as rechargeable batteries for power storage for wind power generation and solar power generation.
