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: An electronic device includes a display portion, an imaging portion, a control portion, an input portion, and a sensor portion. The display portion has a first display element that reflects visible light and a second display element that emits visible light. The display portion has a function of displaying an image using one of or both first light reflected by the first display element and second light emitted from the second display element. The imaging portion takes an image of an object, the control portion controls the display portion and the imaging portion, the input portion inputs a signal for controlling the display portion and the imaging portion to the control portion, and the sensor portion outputs sensing data to the control portion, in consideration of illuminance of external light. Such a display device increases the display quality, or keeps high-quality display regardless of environmental conditions and reduces power consumption.
