A method for displaying a terminal charging status and a terminal. The method includes: displaying a charging status region on a terminal screen when it is detected that a terminal battery is being charged, with a halo enlarging or shrinking with a preset frequency existing at the edge of the charging status region; according to a ratio of the current electric quantity of the terminal battery to the electric quantity of the terminal battery being fully charged, displaying a filled region having the same ratio in the charging status region. The method for displaying a terminal charging status and the terminal can realize visually displaying a charging status and a charging progress of the terminal.

A secondary electrochemical battery sealing body, including a negative electrode cap, a circuit board module and an insulating washer. The circuit board module is connected to the negative electrode cap via a connecting member. A charge indicator is disposed on the circuit board module at the position corresponding to an edge of the negative electrode cap. A notch is formed on the edge of the negative electrode cap as a light transmission port of the charge indicator. The notch has a height which does not exceed the height of the negative electrode cap. The insulating washer is a flexible and elastic annular insulating gasket, and is disposed in a gap between a battery housing, the circuit board module and the negative electrode cap. The insulating washer completely covers the light transmission port of the charge indicator to seal the negative electrode cap, the battery housing and the circuit board module.

Systems, devices, and methods for thermal malfunction detection in a liquid cooled vehicle battery are disclosed herein. Systems can include a housing enclosing at least a portion of one or more electrochemical cells, a flow path at least partially disposed within the housing and at least partially in thermal contact with at least a portion of the one or more electrochemical cells, and a thermal malfunction detector disposed at least partially within the flow path. The thermal malfunction detector can be capable of detecting matter output by the one or more electrochemical cells during a thermal malfunction.

To provide a lithium-ion storage battery or electronic device that is flexible and highly safe. One embodiment of the present invention is a flexible storage battery including a positive electrode, a negative electrode, a separator between the positive electrode and the negative electrode, an exterior body that surrounds the positive electrode, the negative electrode, and the separator, and a wiring provided along the exterior body. At least part of the wiring is more easily breakable by deformation than the exterior body. The wiring is more vulnerable to deformation than the exterior body and thus damaged earlier than the exterior body. Damage to the wiring is detected and an alert is sent to a user; thus, the use of the storage battery can be stopped before the exterior body is damaged.
