A new battery cell structure uses a battery cell structure comprising a plurality of strips so that only a fraction of the power in the cell can be fed to a dendrite which has shorted an anode and cathode. The dendrite still occurs, but can be rendered benign. In addition, a fuse can be added to the cell structure so that shorted cells can be removed from the circuit.

A battery balancing system (100) for parallel connected batteries (101) for balancing batteries that are at dissimilar voltages. The system has a high and a low bus (108, 109), connected by a current limiter (107). The high bus (108) takes energy from the highest voltage battery or batteries in the system and transfers the energy through the current limiter (107) to the low bus (109), which in turn delivers energy to the lowest voltage battery or batteries in the system.

Des Weiteren betrifft die Erfindung eine Batterie mit einer Mehrzahl solche Batteriezellen (10), ein Kraftfahrzeug und ein Verfahren zum Betreiben einer Batteriezelle (10).
摘要:
A nonaqueous electrolyte secondary battery includes: an electrode body that includes a positive electrode and a negative electrode; a battery case that accommodates the electrode body and a nonaqueous electrolytic solution; an external connection terminal that is electrically connected to one electrode of the positive electrode and the negative electrode; and a current interrupt device that interrupts a conductive path, through which the electrode and the external connection terminal are electrically connected to each other, when an internal pressure of the battery case exceeds a predetermined value. The positive electrode includes a positive electrode current collector and a positive electrode mixture layer that contains a positive electrode mixture. When a ratio of an actual capacity to a nominal capacity is 95% or higher, an amount of fluorine contained per 1 mg of the positive electrode mixture is 0.15 μηιοΐ to 0.20 μmol.
