1. A method for producing a conductive composite material for a battery, the method comprising: providing an electrolyte matrix that is ion-conducting and plasticizable, the electrolyte matrix comprising a first ion-conducting substance and a plasticizable base substance or a polyelectrolyte; providing ion-conducting particles; introducing the ion-conducting particles into the electrolyte matrix to produce a mixture consisting of the ion-conducting particles and the electrolyte matrix; homogenizing the mixture with a homogenizing device; and homogenizing the mixture for a length of time of less than 8 hours, wherein the ion-conducting particles and the electrolyte matrix are homogenized so that the ion-conducting particles have a minimum distance of separation of at least 100 nm, and a particle filling of the ion-conducting particles is at least 1% by volume in relation to a total volume of the electrolyte matrix; wherein homogenizing the mixture is selected from the group consisting of: kneading, extruding, and rolling.
