The method, which the scientists referred to as operando electrochemical transmission electron microscopy (TEM) reportedly allowed them to watch chemistry in action and collect real-time movies revealing what happens to energy materials during temperature changes.
“We now have an opportunity to investigate battery operation down to minus 50 degrees Celsius (minus 58 degrees Fahrenheit), as in extremely cold Arctic climates, and catalyst activation and degradation up to 300 degrees Celsius (572 degrees Fahrenheit) as in many industrial catalysts and every car’s catalytic converter,” Yang pointed out.
