摘要: The present invention provides a water based lithium secondary battery that can inhibit deteriorations in capacity owing to charge-and-discharge operations and maintain a high capacity even after it is charged and discharged repeatedly. The water based lithium secondary battery includes a positive electrode, a negative electrode, a separator 4 sandwiched between these, and an aqueous electrolyte solution obtained by dissolving an electrolyte made of a lithium salt in a water based solvent. As the water based solvent, a pH buffer solution is employed. The buffer solution is obtained by dissolving an acid and its conjugate base's salt, a base and its conjugate acid's salt, a salt made from a weak acid and a strong base, a salt made from a weak base and a strong acid, or a salt made from a weak acid and a weak base in water.

摘要: A rotating spraying type coating apparatus having a spraying head attached to a rotating shaft of a rotating drive device, a paint supply passage connected to the proximal end of the spraying head, and a paint radiating portion formed at the distal end of the spraying head to thereby spray paint particles from the paint radiating portion. The apparatus is provided with a partition member which is disposed around the outer periphery of the spraying head in opposing relation to the latter, and at least a pair of air outlet ports which are disposed in such a manner that air is jetted out forwardly from the air outlet ports toward the outer peripheral surface of the partition member. Thus, the direction of spray of paint particles from the paint radiating portion is controlled by means of the jetted air, and it is possible to obtain elliptical and dumbbell-shaped spray patterns which cannot be obtained by the conventional rotating spraying type coating apparatuses.

摘要: An electric power storage system 10 of the present invention includes a lithium secondary battery; a detection device to detect the temperature of the lithium secondary battery; and a control device to decrease a remaining capacity of the lithium secondary battery based on an increase of the detected temperature and a temperature Tbx of the lithium secondary battery. When a self-heating rate of the lithium secondary battery at a temperature T (K) and a remaining capacity x (%) is represented by Hs(x, T) (K/min), and a heat dissipation rate at a temperature T (K) of the lithium secondary battery is represented by Hd(T) (K/min), the temperature Tbx is a temperature at which Hs(x,Tbx)>Hd(Tbx) holds. That is, this temperature Tbx is a temperature at which the heat generating rate is higher than the heat dissipation rate and at which the battery temperature T starts to increase.
