Facility

The Chen laboratory is located in SME Building Room 213 at University of California, San Diego. The laboratory (SME 213) has solid state and solution chemical synthesis capabilities (two chemical hoods), low and high temperature box furnaces and tube furnaces, materials processing equipment, porous materials characterization capability, and electrochemical characterization equipment. The following equipment listing provides details of our major equipment:

Autosorb iQ from Quantachrome, model ASIQM0001000-6. It is a dual-port physisorptiion (chemisorption can be integrated) gas sorption analyzer that is used to analyze surface area, pore size and distribution of porous materials (including both micropore and mesopore analysis capability).

Metrohm Autolab electrochemical workstations , model M204. It is a multi-channel potentiostat/galvanostat which allows different measurements on each channel at the same time. It could perform all kinds of electrochemical measurements including cyclic voltammetry, galvonostatic charging and discharging, electrochemical impedance spectroscopy, etc.

Pine modulated speed rotating electrode system for electrochemical catalytic reaction testing.

Dual-user glovebox from Vigor, model SciLab. The inert atmosphere such as argon or nitrogen is maintained inside the glovebox. Water or air sensitive synthesis, materials preparation and cell assembly are done in this equipment.

Vacuum oven from VWR, model 6291.

Gravity convection oven from Thermo Scientific, model 658.

Forced air convection oven from MTI Corp, model BPG-7032.

Tube furnace from Thermo Scientific, model TF55035A-1.

Tube furnace from Thermo Scientific, model STF55666C-1.

Battery testing systems from LANHE and Neware. The multi-channel battery analyzer could analyze coin cells, cylindrical cells and pouch cells from 1 mA to 1000 mA.

Thinky Mixer: Model ARM-310. This professional mixer is designed to prepare viscous solution and slurries with high homogeneity in a short period of time.

Centrifuge from ELMI, model CM-7S.

Ball mill from SPEX Sample Prep, model 5100.

Analytical balance from Mettler Toledo, model ME104TE.

Multiple magnetic stirrers from Thermo Scientific, model SP88857100.
