Countersink magnets are a practical magnet shape type, in the previous article has introduced the role of sinkhole magnets, today's article for you to introduce it in the lithium battery applications.
With the popularization of intelligent products, the efficient charging and management of lithium batteries has put forward higher requirements. In order to optimize the charging process, improve safety and convenience, the use of 10x3x5mm countersunk magnet ring adsorption lithium battery charging interface is gradually becoming a new solution.
The picture shows the practical application of a 10x3x5mm ndfeb countersunk magnet in lithium batteries, suitable for cylindrical lithium batteries such as 18650 26650 21700.
Principle of the 10x3x5mm sunken hole magnet ring adsorption technology;
The principle of operation of the magnet ring with countersunk holes is based on magnetic attraction. When the battery comes into contact with the charging connector, the magnet ring connects to the metal material (usually electrically conductive) at the contact end of the charger through its powerful magnetic force. The countersunk design of the magnet ring allows it to be precisely positioned, making the contact more stable during charging and reducing the risk of poor or loose contact.
This design ensures a stable electrical connection between the battery and the charger, effectively reducing current loss and heat generation due to poor contact during battery charging, thus improving charging efficiency and safety.
The 10x3x5mm countersunk magnet ring has demonstrated great potential in lithium battery charging systems due to its strong magnetic force, stable adsorption capacity, and simple docking design. With the continuous advancement of technology, magnetic charging interfaces will become a standard configuration for more high-tech products, improving user experience and promoting innovation and development of charging technology.
On the application of magnets in lithium batteries there will be a diameter of 5mm, thickness of 1mm neodymium round magnets placed in the positive pole of the flat battery, so that it becomes pointed, commonly used in the series connection of 2 flat lithium batteries.
That concludes the article. Our company is a permanent magnet manufacturer and can customize various shapes and grades of countersunk magnets according to your application. We welcome your inquiries.
