HEL will be presenting an opening lecture to start off the session on New Energy Landscape on the 15th of November, at IChemE’s Hazards XXIII conference, Institution of Chemical Engineers, at Southport Convention Centre. This institution has pioneered conferences involving the safety of chemicals for over 40 years and this is the 23rd conference in this series.
The lecture is concerned with a different approach to green energy, namely the development of electric vehicles and in particular Li-ion battery research. The chemistry involved in these new, more powerful batteries is quite hazardous if handled without care and under accident conditions can lead to violent explosions. HEL will present both technical data and video evidence, describing the potential hazards of batteries and how these problems can be studied then minimised.
This presentation will focus on the use of adiabatic calorimetry to study battery safety, using its Battery Testing Calorimeter (BTC), which is a version of the classic ‘ARC’ device developed over 30 years ago by Dow Chemical Company. This instrument is mandatory for study of battery safety under “abuse” conditions, including situations such as overheating, overcharging or discharging too fast.
The BTC allows batteries of all sizes and shapes to be tested and helps to define the maximum safe temperature, maximum discharge rate and maximum over-voltage, before a battery or pack undergoes thermal runaway explosion. It will also highlight the use of a related calorimeter, the iso-BTC which operates isothermally and which can be used to study the heat events internal to batteries. The iso-BTC can also provide information for thermal control systems and for understanding how internal heat effects take place at different rates of battery charging and discharging, as well as the effect of environmental temperatures.
HEL is a leading supplier of techniques for the research into green energies including bio-diesel where several different reactor systems for process development have been supplied, focusing particularly on the heterogeneous catalyst screening often involving hydrogenation reactions where the operating pressure and temperature can be rather high. HEL has supplied parallel reactor systems to universities and private industry worldwide and the huge amount of research into alternate, renewable energy is likely to feature increasingly among applications supported by HEL.
