According to one embodiment, a battery module includes first to fourth batteries and a case in which these batteries are housed. In the case, a first partition wall partitions the first and the second batteries and partitions the third and fourth batteries in a first direction, and a second partition wall partitions the first and third batteries and partitions the second and fourth batteries in a second direction intersecting the first direction. A fastening member fastens case members to each other at an intersection of the above two partition walls. The case includes a rib protruding on a surface of at least one of the first and second partition walls.

A battery for use in electronic devices and which is safely ingested into a body and a related method of making the battery. The battery includes an anode, a cathode and a quantum tunneling composite coating. The quantum tunneling composite coating covers at least a portion of at least one of the anode or the cathode and provides pressure sensitive conductive properties to the battery including a compressive stress threshold for conduction. The compressive stress threshold may be greater than a pre-determined applied stress in a digestive tract of the body in order to prevent harm if the battery is ingested. The battery may include a waterproof seal that extends between the quantum tunneling composite coating and a gasket separating the anode and cathode to inhibit the battery from short circuiting in a conductive fluid below the compressive stress threshold.

A battery having flat, stacked, anode and cathode layers. The battery can be adapted to fit within an implantable medical device.

A battery system has a battery with a plurality of battery modules which can be selectively activated or deactivated by means of actuation, wherein, in the activated state, the battery module voltage of a respective battery module contributes to an output voltage of the battery and, in the deactivated state, the battery module is uncoupled from the current path of the battery. The battery system comprises a circuit for charging the battery modules which has components which are arranged in accordance with a switching converter topology, which is integrated in the battery system in such a way that the battery modules can be charged independently of whether a respective battery module which is to be charged is in the activated or in the deactivated state. A method for charging battery modules, a method for balancing battery modules, and a motor vehicle include the battery system.
