Energy Storage

Our Energy storage lab stored energy.

 

For access to the lab, or for any general training, please contact the lab leader Dr Kai Xi, or their deputy Mr Dylan Maxwell.  For training on any of the equipment, please contact the Principal User or their deputy for the listed equipment.

All equipment in the Energy Storage lab needs to be booked before use. The booking system can be found here.

 

Battery Cyclers

Deputy: Mr Dylan Maxwell

DSC Q20
Differential Scanning Calorimeter

Principal User: Dr Kai Xi

Deputy: Mr Dylan Maxwell

The Q20 is a cost-effective general purpose DSC that gives accurate and reproducible data. The Q20 can be equipped with a 50-position autosampler (Auto Q20) that provides a high-throughput platform for basic DSC experiments, with performance comparable to competitive research-grade instruments.

  • Temperature Range: Ambient to 725 ℃
  • Measuring Range: +/- 350 mW
  • Temperature Precision: ± 0.05 ℃

Argon Glovebox

Sartorius Micro Balance

Principal User: Dr Kai Xi

Deputy: Mr Dylan Maxwell

  • Wherever maximum accuracy is required, even for minimal sample quantities
  • Serial weighing that benefits from very fast response times and a fully automatic draft shield
  • µg-accurate weighing of toxic, hygroscopic, or heavily oxidizing samples can be done in laminar flow boxes, glove boxes or under fume hoods
  • Areas with strict demands on cleanliness
  • Differential weighing (ashing or incineration, drying, measurement of coatings, checking spillage quantities, etc.)
  • Mass determination that allows for air buoyancy
  • Air density determination for metrological weight analyses
  • Complete calibration, adjustment and documentation routines for monitoring test and measuring equipment when integrated into a quality system 

VSP-300 Potentiostat

Principal User: Dr Kai Xi

Deputy: Mr Dylan Maxwell

The VSP-300 multichannel potentiostat / galvanostat offering 6 slots to set from 1 to 6 channel boards. Each channel board can accomodate an ultra low current cable and can be  associated with one or several booster kits. Two kinds of booster kits are available: ±4 A / 14 V and ±1 A / 48 V. Up to five boosters of 4A can be plugged in one VSP-300 chassis. They can be  parallelized to reach up to 20 A. Each channel board can be equipped with a linear scan generator. Not only a  multichannel system, this instrument can be controlled independently by several  users thanks to the LAN connection.

Gas Sorption Analyzer (BET instrument)

Principal User: Dr Kai Xi

Deputy: Mr Dylan Maxwell

Simultaneous surface area and pore size analysis of up to four samples with NOVA 4200 for dramatic increase in productivity. Degas up to four samples while pore size and surface area analysis is in progress for maximum throughput. 

Automatic surface area and pore size analysis, computation, display and printing of results. Wide variety of sample cells to accommodate any sample.  Compact, benchtop design to conserve valuable lab space.  Protective doors for safety. 

Thermogravimetric Analyzer (TGA)

Principal User: Dr Kai Xi

Deputy: Mr Dylan Maxwell

This instrument is basically a sophisticated ash content test and is useful in measuring the inorganic filler content of plastics. TGA analysis continuously weighs a sample to the nearest millionth of a gram as it is heated to temperatures of up to 1000°C. As the temperature is increased, various components of the sample burn off and the weight percentage of each can be measured. Results are in the form of a graph with temperature plotted on the X-Axis and weight percentage plotted on the Y-Axis. A typical TGA scan looks similar to a staircase with each step representing a different compound. Our typical run is to ramp at 10°C per minute to 700°C in nitrogen followed by 10°C per minute to 900°C in air. Highly volatile matter is the material that burns off in nitrogen between ambient and 150°C. Medium volatile matter is the material that burns off in nitrogen between 150°C and 700°C. Combustible matter is the material that burns off in air but not in nitrogen at 700°C. Ash content is the material left at 900°C in air
