Category: Batteries

The electrically active material compromising the electrodes of most modern battery designs are powders and require a mechanical support structure to hold them in place during the manufacturing process. This support structure also functions as a current collector and provides the electrical connection point for the external circuit. In the battery production, the expanded metal foils are coated with active electrode material and then roll to cylinder, which is the main structure of battery core.

Description

Product Description

In addition to the anode material, cathode material, separator (also known as membrane) and electrolyte, the Current Collector is really an indispensable part of the battery. The main role of the collector is to collect and transfer electrons to ensure the smooth flow of current between the internal and external circuits of the battery. In batteries, anodic current collector or cathodic collector connect the anodic material or cathodic material respectively, and conduct the current flow to the outside of the battery.

As a common material of current collector, expanded metal mesh/foil has the following characteristics

●Improve active material utilization

●Reduce battery internal resistance

●Increase battery cycle life

●Increase battery stability and safety

●Reduce battery cost

KINSON can provide processing technology and value-added services like

1. Flatten mesh: make the metal mesh and raw material thickness consistent, forming a smooth mesh surface, can also be lower than the thickness of the raw material to enhance the strength of the finished product.

2. Raising mesh: after expanding the mesh process to form products, can increase the overall thickness of the product.

3. Edge-folding process.

4. Solid foil at intervals along with the mesh.

5. Heat treatment.

6. Continuous plating process.

7. Continuous sand blasting process.

Aerospace

Generally speaking, metal aircraft made of aluminum can be used safely for decades, because the metal aircraft's own electrical conductivity is enough to protect the aircraft from lightning strikes, with the development of science and technology, composite materials are widely used in aviation aircraft, when lightning strikes or lightning current flows through the composite structure, it will cause this composite structure embrittlement, delamination or fracture. And the most serious damage to the composite structural parts is usually the highest energy density of the lightning inflow point or out point.

Wind turbine blade lightning protection net

In the current wind power market, the composite materials, because of its unique performance advantages to become the mainstream of wind turbine blades, in order to achieve high-strength and lightweight. The traditional flashing system can not provide complete protection. In the cases of actual lightning damage, the lightning strike can bypass the flashing device and hit the blade, which is very common.

Electromagnetic Shielding

The screen net can not only shield electromagnetic radiation interference, but also transmit light, so it is the only available shielding material for observation and display holes. At present, it has been widely used in radar display, computer display terminal, printer, radio, spectrum meter, precision instrument and so on digital and image display window, electronic shelter and electromagnetic shielding of shielding room observation window.

Industrial

Expanded metals, along with our other metal alternatives, is manufactured with no waste and is available in 2D and 3D appearances. It has exceptional corrosion, heat, and impact resistance. The unique properties of lower and higher alloyed grades provide resistance to corrosion in many different environments. Moreover, 2D and 3D appeared can expand the area and carry much more catalysts. The manufacturing process adds rigidity to the original material and the mesh can be annealed to improve its formability. Expanded metal mesh is a versatile and durable one-piece construction that is used for a wide range of applications. Industries we commonly serve include HVAC services, filtration, petrochemical, food service, automotive, acoustics, architecture and more.
