    Abstract: Disclosed is a power storage unit which can safely operate over a wide temperature range. The power storage unit includes: a power storage device; a heater for heating the power storage device; a temperature sensor for sensing the temperature of the power storage device; and a control circuit configured to inhibit charge of the power storage device when its temperature is lower than a first temperature or higher than a second temperature. The first temperature is exemplified by a temperature which allows the formation of a dendrite over a negative electrode of the power storage device, whereas the second temperature is exemplified by a temperature which causes decomposition of a passivating film formed over a surface of a negative electrode active material.

    Abstract: Disclosed is a power storage device including a negative electrode and a positive electrode. The negative electrode includes a negative electrode current collector including a common portion and a plurality of protrusions protruding from the common portion, and a negative electrode active material layer which covers a side surface of the protrusion. The positive electrode faces the negative electrode with an electrolyte provided therebetween. In the plurality of protrusions, a distance between adjacent protrusions is a distance with which adjacent negative electrode active material layers are in contact with each other before the capacity of the negative electrode active material layer reaches the theoretical capacity of the negative electrode active material layer by insertion of carrier ions from the positive electrode.

    Abstract: A secondary battery suitable for a portable information terminal or a wearable device is provided. An electronic device having a novel structure which can have various forms and a secondary battery that fits the forms of the electronic device are provided. In the secondary battery, sealing is performed using a film provided with depressions or projections that ease stress on the film due to application of external force. A pattern of depressions or projections is formed on the film by pressing, e.g., embossing.

    Abstract: The adhesion between metal foil serving as a current collector and a negative electrode active material is increased to enable long-term reliability. An electrode active material layer (including a negative electrode active material or a positive electrode active material) is formed over a base, a metal film is formed over the electrode active material layer by sputtering, and then the base and the electrode active material layer are separated at the interface therebetween; thus, an electrode is formed. The electrode active material particles in contact with the metal film are bonded by being covered with the metal film formed by the sputtering. The electrode active material is used for at least one of a pair of electrodes (a negative electrode or a positive electrode) in a lithium-ion secondary battery.

    Abstract: A charging device used for charging a storage battery includes a first circuit that generates a current which depends on a charging current of the storage battery; a second circuit in which charge is accumulated by periodical supply of the current which depends on the charging current; and a third circuit that outputs a signal indicating completion of charge of the storage battery when the potential of the second circuit reaches a reference potential. The second circuit includes a capacitor and a transistor in which an oxide semiconductor is used for a channel formation region. The transistor is turned on or off in response to a pulse signal input to a gate of the transistor. The capacitor accumulates charge when the current depending on the charging current flows through the transistor.
