The battery contact / shrapnel is an important component of the battery, which has the following characteristics:
Strong electrical conductivity: The battery contact has good conductivity, which can ensure the stable transmission of current and reduce resistance and power consumption.
Good elasticity: The battery shrapnel has good elasticity and resilience, which can return to its original state after the pressure is released, and adapt to the deformation and vibration of the battery during use.
Strong mechanical properties: The battery contact has a certain strength and toughness, which can withstand various external forces during the use of the battery, and is not easy to deform or damage.
Good corrosion resistance: Battery contact / shrapnel is usually made of stainless steel, copper and other materials with good corrosion resistance, which can adapt to corrosive factors such as chemicals or humidity in the battery working environment.
Easy installation: The battery shrapnel is usually installed on the battery conductive film, which is easy and quick to install, and can quickly complete the assembly and production of the battery.
Battery shrapnel has the characteristics of strong conductivity, good elasticity, strong mechanical properties, good corrosion resistance, easy installation, etc., and is an important part of the battery, which is widely used in various electronic devices.
The U Shape Copper Metal Stamping offers a number of important features and application advantages:
Excellent conductivity: high conductivity of copper ensures high efficiency and stability of battery current transmission and reduces energy loss and heating problems. For example, in a high-performance battery pack, this highly effective conductivity facilitates fast charging and discharging.
Precise size and shape control: the punching process can produce the U-shaped parts with accurate size and consistent shape to ensure the close and accurate contact with the positive and negative poles of the battery.
Good elasticity and recovery capacity: the contact can maintain good contact pressure during repeated plug and use to ensure the reliability of connection.
High-temperature resistance: it can still maintain the stability of its physical and electrical properties under the high temperature environment that may occur during the operation of the battery.
It is widely used in different fields:
In the field of consumer electronics, such as contacts of laptop batteries, U-shaped copper stamping parts can provide stable power connection and support normal operation of equipment.
In the new energy vehicle, the internal connection of the power battery also often adopts this kind of stamping parts to deal with the large current and complex working conditions.
However, it also has some challenges:
High material cost: copper is relatively expensive, which may increase the battery production cost.
Great processing difficulty: high requirements for stamping die and process, and high-precision equipment and technical support are required.
