Lithium-ion battery coating separator peeling test machine Lithium-ion battery separator is one of the core key materials, and is a key component that restricts battery safety and cycle life
.
The main function of the separator is to separate the positive and negative electrode materials of the battery to prevent short circuit due to contact between the two electrodes, while the electrolyte ions pass through it
.
On the premise that the thickness is as thin as possible, it is necessary to ensure a certain physical and mechanical strength, including tensile strength, puncture strength, peel strength,
etc.
Definition of peel strength: The load per unit width that can withstand when the bonded sample is separated under the specified peeling conditions
.
Product model: WDB-01 Product use: With lithium ion battery polyethylene (PE) and other separators as the matrix, the uniform coating thickness on the surface is 1~2μm mixed with nano-alumina powder and gelling agent slurry, which can be used to make Inorganic composite ceramic coating lithium-ion battery separator
.
Ceramic-coated separators can effectively improve the thermal safety of lithium-ion batteries, and at the same time have good wettability and liquid retention properties for electrolytes, which can effectively improve the capacity retention performance of lithium-ion batteries
.
The quality of the coating is directly related to the performance of the battery's electrical performance.
The peel strength test can not only effectively identify the coating quality, display the slurry coating strength, uniformity and other indicators, but also guide the adjustment of the coating production line, so that the The finished product is more uniform and reliable
.
It can do mechanical properties tests such as longitudinal, transverse tensile, tensile, and tear properties of various papers, films, rubber, plastics, textiles, waterproof materials, non-woven fabrics, metal wires, metal foils, and metal sheets.
, self-adhesive and other adhesive materials peeling, splitting, shear strength test, elongation at break test, heat sealing tensile, tearing, strength test, etc.
