Abstract: To provide a positive electrode active material in which a phase transition is inhibited and a secondary battery including the positive electrode active material. An unprecedented synthesis method has been developed in which lithium cobalt oxide particles are treated with a molten salt of MgF2—LiF as a reaction accelerator to facilitate the diffusion and doping of magnesium into lithium cobalt oxide bulk and to form a stable coating layer in the particle surface portion. Ex situ XRD analysis confirms the inhibition of the harmful phase transition and the emergence of a novel phase as the modified LiCoO2 is charged up to 4.7 V. The modified LiCoO2 shows high electrochemical performance during high-voltage operation. This technology provides a guideline for suppressing fundamental degradation associated with phase transition and achieving ultra-high energy density LiCoO2 positive electrodes.

Abstract: A positive electrode active material that has high capacity and excellent charge and discharge cycle performance for a secondary battery is provided. A positive electrode active material that inhibits a decrease in capacity in charge and discharge cycles is provided. A high-capacity secondary battery is provided. A secondary battery with excellent charge and discharge characteristics is provided. A highly safe or reliable secondary battery is provided. A positive electrode active material contains lithium, cobalt, oxygen, and aluminum and has a crystal structure belonging to a space group R-3m when Rietveld analysis is performed on a pattern obtained by powder X-ray diffraction. In analysis by X-ray photoelectron spectroscopy, the number of aluminum atoms is less than or equal to 0.2 times the number of cobalt atoms.

Abstract: A positive electrode active material has a small difference in a crystal structure between the charged state and the discharged state. For example, the crystal structure and volume of the positive electrode active material, which has a layered rock-salt crystal structure in the discharged state and a pseudo-spinel crystal structure in the charged state at a high voltage of approximately 4.6 V, are less likely to be changed by charging and discharging as compared with those of a known positive electrode active material. In order to form the positive electrode active material having the pseudo-spinel crystal structure in the charged state, it is preferable that a halogen source such as a fluorine and a magnesium source be mixed with particles of a composite oxide containing lithium, a transition metal, and oxygen, which is synthesized in advance, and then the mixture be heated at an appropriate temperature for an appropriate time.

Abstract: An information processing apparatus is configured to communicate with a communication terminal. The apparatus includes a receiver, circuitry, and a transmitter. The receiver receives, from the communication terminal, a transmission request that requests that the information processing apparatus transmit a disconnection request to the communication terminal. The disconnection request is a request for requesting disconnection of a communication between the information processing apparatus and the communication terminal. The circuitry issues, in response to receiving the transmission request, an instruction for transmission of the disconnection request to the communication terminal. The transmitter transmits the disconnection request to the communication terminal in accordance with the instruction. The transmitter disconnects the communication between the information processing apparatus and the communication terminal in response to receiving a reply to the disconnection request from the communication terminal.
