摘要： The invention relates to a method of purifying an ionic electrolyte containing at least one alkaline earth salt, said method comprising at least one contact step involving particles of at least one calcium salt. The inventive method can be used to obtain novel electrolytes which are especially characterised by the particularly-low water content thereof. The corresponding electrochemical generators that contain the electrolyte as a component are characterised by excellent stability and are very secure.

摘要： The invention relates to a mixture of particles comprising a non-conducting or semi-conducting core which is covered with a conducting hybrid coating and hybrid conducting chains which are located between the particles of the mixture and which form a conductivity network, said mixture being prepared by means of mechanical crushing. The incorporation of said particle mixtures in the anodes and cathodes of electrochemical generators is advantageous owing to the very high conductivity of the network, the low resistivity, the excellent high current capacity and/or the good energy density thereof. In this way, the inventive particle mixture can be used to produce highly-performing electrochemical systems.
