An object to be cooled is quickly brought to a suitable temperature. An object to be cooled is quickly brought to a suitable temperature. A thermal energy storage packaccording to the present invention is a thermal energy storage pack that performs temperature management of food and/or beverage, and includes a first deep-drawn container filled with a first thermal energy storage material that exhibits phase change at a predetermined temperature, a second deep-drawn container that is overlaid by the first accommodation portion and that is filled with a second thermal energy storage material that maintains a liquid phase state at the phase change temperature of the first thermal energy storage material, and a cover material that closes off the first deep-drawn container. The second deep-drawn container comes into contact with a wine bottle.

A positive electrode for lithium ion secondary batteries includes a collector and a positive electrode active material layer formed on at least one surface of the collector. The positive electrode active material layer contains a lithium-containing metal oxide having a unit cell represented by the following formula and a conductive material and has voids with a volume of 0.82&#xd7;10cm/cmto 7.87&#xd7;10cm/cmper unit area of the collector:LiFeZrPSiO&#x2003;&#x2003;(1)where 0&#x3c;x&#x3c;1 and 0&#x3c;y&#x3c;1. The unit cell has lattice constants satisfying 10.326&#x2266;a&#x2266;10.335, 6.006&#x2266;b&#x2266;6.012, and 4.685&#x2266;c&#x2266;4.714. The sum of the volume of the lithium-containing metal oxide and the volume of the conductive material is 1.61&#xd7;10cm/cmto 6.46&#xd7;10cm/cmper unit area of the collector.

Provided is a cathode active material which is superior in safety and cost and makes it possible to provide a nonaqueous secondary battery having a long life. The cathode active material has a composition represented by the following formula (1):LiMnMPAlO&#x2003;&#x2003;(1) (wherein M is at least one selected from the group consisting of Ti, V, Zr, Sn and Y, x is in a range of 0&#x3c;x&#x2266;0.5, and y is in a range of 0&#x3c;y&#x2266;0.25).

Cathode active material, cathode, and nonaqueous secondary battery

A cathodic active material for a nonaqueous electrolyte secondary battery according to the invention includes a lithium-containing transition metal phosphate containing Li and a transition metal. A transition metal site and P site of the lithium-containing transition metal phosphate are replaced by elements other than elements contained in the lithium-containing transition metal phosphate, and the quantity of P site is excessive with respect to a stoichiometric proportion of the lithium-containing transition metal phosphate. With this cathodic active material, a high-power and high-capacity secondary battery which is superior in safety and cost and has superior rate performance can be provided.
