The present invention provides a method for producing a ceramic laminate capable of preventing coming-off of materials and warpage of the ceramic laminate by a heat treatment at a relatively-low temperature, and a ceramic laminate produced by the production method. Disclosed is a method for producing a ceramic laminate having a layer structure in which two or more layers are laminated, including: a step of producing a laminate including a first layer and a second layer, the first layer containing a solid electrolyte and the second layer containing at least composite particles obtained by covering an electrode active material with the solid electrolyte; and a step of performing a heat treatment on the laminate including the first and second layers at a temperature of 500&#xb0; C. or more and less than 700&#xb0; C.

Method for producing ceramic laminate

A lithium ion battery before pre-doping includes: a negative electrode member before initial charge having a negative active material before initial charge; a positive electrode member; an electrolyte body; a battery case; and a lithium ion supply body formed by a lithium compound capable of emitting lithium ions when positive voltage is applied to it. The lithium ion supply body is arranged so that it is at least partially in contact with the inner exposed surface of the battery case. The negative electrode member before pre-doping is electrically insulated from the metal case member. The lithium ion supply body and the negative active material before initial charge are respectively in contact with the electrolyte body.

Lithium ion battery before pre-doping and lithium ion battery manufacturing method

A lithium-ion battery comprises a negative electrode, a positive electrode, and an electrolyte including a molten salt. The positive electrode comprises an electroactive compound including phosphorus, oxygen, lithium, and at least one other metal or semi-metal. The combination of such electrode compositions and a molten salt electrolyte provides a battery with very high thermal stability. Other ions, such as alkal metal ions, may be used in place of lithium ions for applications in other battery technologies.

Battery with molten salt electrolyte and phosphorus-containing cathode

A battery comprises a first electrode, a second electrode, an electrolyte, and an electron collector associated with the first electrode, the electron collector having a surface treatment, such as a protection layer, that reduces corrosion of the electron collector by the molten salt electrolyte.
