Graphite material for negative electrode of lithium ion secondary cell and method for producing the same

The carbon porous body of the present disclosure includes micropores and mesopores. A micropore volume determined at a temperature of 77K by as plot analysis of a nitrogen adsorption isotherm is 100 (cm(STP)/g) or more. A BET specific surface area determined from the nitrogen adsorption isotherm is 1,000 m/g or more. The derivative of the nitrogen adsorption isotherm is 300 (cm(STP)/g) or more over the range where relative pressure P/Pin the nitrogen adsorption isotherm is from 0.10 to 0.20 inclusive, and the derivative of the nitrogen adsorption isotherm is 200 (cm(STP)/g) or more over the range where the relative pressure P/Pin the nitrogen adsorption isotherm is from 0.20 to 0.95 inclusive. The amount of nitrogen adsorbed when the relative pressure P/Pin the nitrogen adsorption isotherm is 0.98 is 1,200 (cm(STP)/g) or more.

A F-type electrochemical cell, which is a lithium air battery, includes a positive electrode facing a negative electrode composed of metallic lithium with a separator provided therebetween in a casing. Air is capable of flow to the positive electrode. A nonaqueous electrolytic solution is charged into a space between the positive electrode and the negative electrode. At least one of the positive electrode and the nonaqueous electrolytic solution of the lithium air battery contains a compound having a stable radical skeleton. The compound also serves as a redox catalyst for oxygen.

Alkali metal air battery

A novel electrocatalyst made of an oxidase having high electron transfer efficiency and an enzymatic electrode using the same are provided. The electrocatalyst is made of CueO. The enzymatic electrode comprises a carbonaceous porous body and an electrocatalyst made of CueO supported on the surface of the carbonaceous porous body. CueO is preferably CueO from. The carbonaceous porous body constituting the enzymatic electrode is preferably carbonaceous gel. Also, the enzymatic electrode may further comprise a mediator which facilitates transfer of electron between the carbonaceous porous body and said CueO.

Electrocatalyst and enzymatic electrode

A coated material comprising a substrate which has micropores and a reaction product coated thereon along the surface configuration of the substrate and an inner wall of the micropores thereof. The coated material is preferably produced by performing a supercritical coating step wherein a reaction precursor is dissolved in a supercritical fluid to form a precursor fluid and then the precursor fluid is brought into contact with a substrate in the presence with a reaction initiator to allow a reaction between the reaction precursor and the reaction initiator, thereby coating a reaction product onto the substrate.
