Method for the production of a porous element, and cell of a rechargeable oxide battery

A method for producing a porous element is presented. A powdery metal-ceramic composite material is produced. The composite material has a metal matrix and a ceramic portion amounting to less than 25 percent by volume. The metal matrix is at least partially oxidized to obtain a metal oxide. The meta...

Beschreibung
Zusammenfassung:	A method for producing a porous element is presented. A powdery metal-ceramic composite material is produced. The composite material has a metal matrix and a ceramic portion amounting to less than 25 percent by volume. The metal matrix is at least partially oxidized to obtain a metal oxide. The metal-ceramic composite material is grinded and mixed with powdery ceramic supporting particles to obtain a metal-ceramic/ceramic mixture. The metal-ceramic/ceramic mixture is shaped into the porous element. The porous element can be used as an energy storage medium in a battery.
