Copper Electroplating PP Film, 6.5 Micron, Ideal Substitute For Pure Copper Foil Film, Excellent Cost Effectiveness
Copper Electroplating Polymer Film Structure and Product Advantages
Safety Improving | The base film made of polymer largely reduces the risk of out-of-control events such as short circuit due to punctures, overheating, etc.,and greatly improves the combustion safety factor. |
Energy Density Increasing | The middle layer of the composite current collector is made of lightweight polymer material that is 50-80% lighter than a pure metal current collector, increasing the battery's energy density by 5-10%. |
Extended Service Life | The elastic modulus of the polymer material is lower than that of metal, and a layered annular sponge structure is formed around the active material layer of the battery. The active material layer of the pole-piece expands due to the intercalation and desorption of lithium ions during the expansion and contraction of the active material layer of the pole-piece, and shrinks. During the charging and discharging process of the battery, the electrode interface absorbs stress to maintain long-term integrity, and the battery cycle life is increased by 5%. |
Compatibility | The current collector is not an integral part of the lithium ion transport inside the battery, and direct upgrading of a conventional current collector to a compound current collector does not affect the electrochemical reaction inside the battery. |
This product is an ideal substitute for pure copper foil film that will bring an excellent cost effectiveness.
