Relationship between the total energy efficiency of a sodium-sulfur battery system acid the heat dissipation of the battery case
The relationship between the total energy efficiency of an Na/S battery system and the heat dissipation through its battery case, was investigated. The total energy efficiency was heavily influenced by the heat dissipation of the battery case, and little influenced by the energy efficiency of its cells. In order to obtain a higher total energy efficiency, it is essential to design the battery case with less heat dissipation.
