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 system for an elevator includes at least one battery and an energy exchanger coupled to the at least one battery and configured to let a DC bus float between a first voltage and a second voltage. An energy storage device is coupled to the energy exchanger. The energy storage device is configured to recapture energy that is not recaptured by the at least one battery during a run of the elevator. The energy storage device is also configured to provide energy to the elevator when demand for energy by the elevator exceeds a threshold.

A system for explosively applying a fire-fighting foam is provided. The system includes a thermoelectric generator that is attached to a battery heat source. A temperature differential across the thermoelectric generator generates an electrical current having a temperature-dependent voltage. A detonator circuit is electrically connected to the thermoelectric generator. The detonator circuit measures the voltage of the electrical current. An explosive foam applicator is communicatively connected to the detonator circuit and includes a trigger mechanism that detonates a propelling charge in response to receiving a signal from the detonator circuit when the detonator circuit determines that the electrical current corresponds to temperature that is greater than or equal to a threshold temperature. The explosive foam applicator is oriented such that detonating the propelling the charge causes the explosive foam applicator to apply a foam to the battery heat source.

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

A cell for an electrical energy store is provided, including a cell housing within which there is arranged an electrode and on the outer side of which there is arranged a terminal which is galvanically connected to the electrode, wherein an electrical securing element is connected in a current path between the terminal and the electrode for the purposes of galvanic separation of the electrode and of the terminal. The cell is characterized by having the securing element arranged outside the cell housing. In this way, it is possible in a simple manner for the state of charge of the cell to be checked, and also for the cell to be discharged, from the outside.

A Low Earth Orbit (LEO) satellite has 95 to 105 minutes orbit time with only 60-65 minutes available for recharging. Due to the low charge capability of a Li-ion graphite cell, depth of discharge is limited for this application. The cell of the invention using a lithiated titanate oxide or a titanate oxide able to be lithiated in the negative electrode allows increase of depth of discharge. Increasing charge rate without amplifying capacity loss per cycle allows improvement of useful specific energy per cycle. Depth of discharge values up to 70-80% can be envisioned. Even if the cell exhibits low specific energy, the LEO application is a specific case where useful energy per cycle can be optimized to 70 to 80 Wh/kg.
