The Challenge

The portable water purifier is a water purifier developed by Coway that can be used without mains power. However, the main problem faced by this water purifier is that in a humid and watery environment, it is easy to cause battery failure.

Short Battery Life

The battery pack fails to meet usage requirements after 300 cycles.


Finding A Solution

Ufine Battery improves the battery processing technology and battery cycle life based on the usage of this product.

1. The contact points of the finished battery are gold-plated to prevent rust caused by moisture. This also avoids the problem of contact point capacity rusting after long-term use.

2. Before battery processing, the protective board should be treated with waterproof glue. After the finished battery is assembled, the entire battery is filled with glue to make it 100% waterproof. This will prevent internal connection failure due to moisture. Situations that cause the battery pack to fail to function properly are eliminated.

3. Improve the cycle life of single battery cells. The life of a single battery cell has been increased from 300 to 1,000 times, and the life of the finished battery pack has been increased to more than 500 times. This ensures that the battery can meet normal use during the product life cycle.
