Pin Battery (Pin-Type Lithium Battery)

   Excellence of the pin battery product

1. Dry Room of JNJ

The Dry Room is a very important factor in the battery manufacturing.

Due to the nature of the lithium battery, the moisture in the raw material of the battery lowers the performance and accelerates electrical discharge. Therefore, JNJ made a major investment in the Dry Room and implemented in the whole process.

2. Sealing of Pin Battery

The second most important factor in the battery is the sealing.

If the sealing is bad, the liquid material inside the battery could leak, which causes product quality problems and also damages the product in use of the battery.

 

JNJ prevented leakage by use of high-performance sealing rubber and precision contact technology JNJ developed on its own.
