Lead-free piezoelectric materials for energy harvesting applications.
Energy-storage is pivotal in unlocking the full potential of green electricity derived from renewable energy sources. Currently, chemical batteries and fuel cells stand out as primary contenders for storing this electricity in the form of chemical energy. However, a significant limitation they face is their slow charging/discharging rates, which presents a bottleneck for the rapidly growing electric vehicle market. It takes over an hour to charge an electric car.
