Evaluation of Lithium Ion Battery

Our competency

We have started to develop R&D of LIB since 1991, and the analysis experiences including disassembly reach to more than 2,000 individual LIB cells, from consumer usage to traction usage for EV.
Accumulated knowledge for LIB analysis lies on disassembly technology, sample transport and electro-chemical measurement under inert atmosphere..
