Abstract: A positive electrode active material in which a discharge capacity decrease due to charge and discharge cycles is suppressed and a secondary battery including the positive electrode active material are provided. A positive electrode active material in which a change in a crystal structure, e.g., a shift in CoO2 layers is small between a discharged state and a high-voltage charged state is provided. For example, a positive electrode active material that has a layered rock-salt crystal structure belonging to the space group R-3m in a discharged state and a crystal structure belonging to the space group P2/m in a charged state where x in LixCoO2 is greater than 0.1 and less than or equal to 0.24 is provided.

Abstract: The present invention relates to a secondary battery and an electronic device. The secondary battery includes a positive electrode active material which exhibits a broad peak at around 4.55 V in a dQ/dVvsV curve obtained when the charge depth is increased. The secondary battery includes a positive electrode active material which, even when the charge voltage is greater than or equal to 4.6 V and less than or equal to 4.8 V and the charge depth is greater than or equal to 0.8 and less than 0.9, does not have the H1-3 type structure and can maintain a crystal structure where a shift in CoO2 layers is inhibited. The broad peak at around 4.55 V in the dQ/dVvsV curve indicates that a change in the energy necessary for extraction of lithium at around the voltage is small and a change in the crystal structure is small. Accordingly, the positive electrode active material hardly suffers a shift in CoO2 layers and a volume change and is relatively stable even when the charge depth is large.

Abstract: An occurrence of a dimple during glass polishing is suppressed by scraping a fine scratch that will become the dimple to be grown in a pre-polishing, followed by main polishing. However, at a mark of the dimple in which the growth thereof is suppressed in the pre-polishing, fine roughening of a surface is generated. Further, a polishing liquid containing hydrofluoric acid, an alkali metal, water, and a surfactant that is a sulfonic acid-type or sulfate-type surfactant can suppress excess crystal growth of a deposit formed in a fine scratch in pre-polishing and suppress roughening of a surface after polishing.

Abstract: When an alkali-free glass is polished with a polishing liquid containing hydrofluoric acid as a main component, a sludge is generated on a glass surface and in a storage unit and a pipe of a polishing device. As a result, there arise problems such as deterioration of quality and stopping of the device. A washing liquid that dissolves a sludge containing aluminum and fluorine produced in a glass polishing device is characterized by containing Al3+ ions, and a sludge formed by bonding a divalent element such as Mg, Ca, Sr, and Ba with Al and F can be dissolved with this washing liquid. The problems are solved by washing the inside of the polishing device with this washing liquid.
