Abstract: A high energy density rechargeable metal-ion battery includes an anode energy layer, a cathode energy layer, a separator for separating the anode and the cathode energy layers, an anode current collector for transferring electrons to and from the anode energy layer, the battery characterized by a maximum safe voltage for avoiding overcharge, and an interrupt layer that interrupts current within the battery upon exposure to voltage in excess of the maximum safe voltage. The interrupt layer is between the anode energy layer and current collector. When unactivated, it is laminated to the cathode current collector, conducting current therethrough. When activated, the interrupt layer delaminates from the anode current collector, interrupting current therethrough.

Abstract: A battery cell may be formed to include a surplus lithium. The surplus lithium may be disposed inside a cavity formed by winding a separator, a positive electrode, and a negative electrode to form a jelly roll of the battery cell. The surplus lithium may be discharged in order to pre-lithiate the battery cell. For example, the surplus lithium may be coupled with the positive electrode and discharged while the battery cell is at least partially charged. Alternatively, the surplus lithium may be coupled with the negative electrode and discharged while the battery cell is at least partially discharged. Moreover, the surplus lithium may be coupled with a negative current collector of the battery cell in order to prevent one or more chemical reactions triggered by an over discharge of the battery cell from corroding the negative current collector of the battery cell.

The method comprises the following steps: embedding strain sensors in a plurality of scrapers of a scraper conveyor to measure the tension of weak coupling points between the scrapers and chains, converting acquired sensor signals into data signals through an A/D conversion unit, transmitting the data signals to a data control center using a wireless transmission module, further processing the tension data information of the weak coupling points through the data control center, establishing a chain tension distribution model, and determining an the estimated tension of the chain of the scraper conveyor. The method provided by the present invention is simple, efficient and practical, and the estimation of tension of the whole continuous moving chain is completed by the tension measurement at limited positions of the chain.

The delamination of the first electrode and/or the second electrode may generate at least one nonconductive gap that interrupts a current flow within the battery.
