METHOD FOR THE PRODUCTION OF A POROUS ELEMENT, AND CELL OF A RECHARGEABLE OXIDE BATTERY

摘要

The invention relates to a method for producing a porous element (2), comprising the following steps: - producing a powdery metal-ceramic composite material (4) comprising a metal matrix (6) and a ceramic portion (8) amounting to less than 25 percent by volume; - at least partially oxidizing the metal matrix (6) to obtain a metal oxide (10); - grinding the metal-ceramic composite material (4); - mixing the ground metal-ceramic composite material (4) with powdery ceramic supporting particles (12) to obtain a metal-ceramic/ceramic mixture (14); - shaping the metal-ceramic/ceramic mixture (14) into the porous element (2). The invention also relates to the preferable use of said porous element (2) as an energy storage medium in a battery.
