3results about How to "Improve power reliability" patented technology

The application provides a battery monomer, a battery device and a power utilization device. The battery monomer comprises a shell and an electrode assembly; the shell comprises a mounting wall provided with an electrode terminal; the electrode assembly is accommodated in the shell and comprises a main body and a tab, the tab being connected to one end of the main body facing the mounting wall in a first direction; the mounting wall has a first inner surface facing the electrode assembly, the first inner surface is formed with a recess, the recess extends to at least one edge of the first inner surface, and at least part of the tab is accommodated in the recess. The space inside the shell can be fully utilized, the volume of the battery monomer is reduced, the energy density of the battery monomer is improved, the space of the recess is larger, the tab can be accommodated in the recess to a larger extent or a tab with a larger size can be accommodated in the recess, the tab occupies less space outside the recess inside the shell, and the energy density of the battery monomer is further improved.

The application provides a battery device and an electric device. The battery device comprises a battery cell, a box body and a temperature detection assembly. The battery cell has a pressure relief component for relieving the pressure inside the battery cell. The battery cell is accommodated in the box body. The box body has an exhaust passage for guiding the substances discharged from the pressure relief component to the outside of the box body. The temperature detection assembly comprises a protective shell and a temperature detection piece. The temperature detection piece is used for detecting the temperature in the exhaust passage. The protective shell is installed on the passage wall of the exhaust passage. At least part of the protective shell is located in the exhaust passage. At least part of the temperature detection piece is located in the exhaust passage. The temperature detection piece is accommodated in the accommodation cavity of the protective shell, so that the risk of damage of the temperature detection piece can be reduced. The protective shell is installed on the passage wall of the exhaust passage, so that the stability of the temperature detection assembly can be improved, and the ability of the temperature detection assembly to resist external impact can be improved.
