Who is Youmecs.com?

In 2013, among all functional coating battery separator manufacturers, YOUME was just a small reseller of battery separators. Our founder Jack Chiang learned battery separator is a vital material for securing the safety of batteries. And there is a great demand for battery separators with the growth of the battery business. Moreover, battery separators hold a large cost proportion of lithium battery manufacturing.

With the fast-growing demand for lithium batteries, finally, in 2016, he established the YOUME factory to produce ceramic-coated separators. YOUME’s manufacturing facility is located in Dongguang, China.

In the beginning, YOUME mainly focused on producing and developing ceramic-coated separators. After 6 years of growth, our product range covers all coated battery separators.
