Energy density is a measure of the amount of energy stored in a given system or region of space per unit volume or mass, crucial for evaluating the efficiency of energy storage systems. It plays a vital role in various applications, from batteries and fuels to food and materials, influencing performance, sustainability, and technological advancement.
Plug-in Hybrid Electric Vehicles (PHEVs) combine a conventional internal combustion engine with an electric motor and a rechargeable battery, allowing for both gasoline and electric-powered driving. They offer greater fuel efficiency and lower emissions than traditional vehicles, with the flexibility of using electric power for shorter trips and gasoline for longer distances.
Battery operation involves the conversion of stored chemical energy into electrical energy to power devices. This process is governed by electrochemical reactions within the battery cells, which can be recharged or disposed of depending on the battery type.
