We offer analysis services for a range of batteries, such as lithium-ion rechargeable batteries (LIB) (which have drawn attention as next generation energy sources that offer high performance and are environmentally-friendly), fuel cells (FC), and photovoltaic cells (PV). We analyze, test, and evaluate a wide range of materials and parts, including disassembly in inert atmospheres (such as helium or argon), component parts of batteries (such as electrolytes, catalysts, electrodes, binders, separators), and even generated fluid.
