Abstract
Official abstract text for this publication.
The present invention relates to an electrode material for an electrochemical energy accumulator, in particular for a lithium-ion cell, comprising particles (10, 10′, 10″) of an active material (12) which can be lithiated, wherein the particles (10, 10′, 10″) are partially coated with a lithium-ion-conducting solid electrolyte (14), the solid electrolyte layer (14) having recesses (16).
First claim
Opening claim text (preview).
1 . An electrode material for an electrochemical energy store, comprising particles ( 10 , 10 ′, 10 ″) of a lithiatable active material ( 12 ), where the particles ( 10 , 10 ′, 10 ″) are partly coated with a lithium-ion-conducting solid electrolyte layer ( 14 ), characterized in that the solid electrolyte layer ( 14 ) has recesses ( 16 ). 2 . The electrode material as claimed in claim 1 , characterized in that a width (B) of the recesses ( 16 ) in the solid electrolyte layer ( 14 ) is in the range from 10 nm to 800 nm. 3 . The electrode material as claimed in claim 1 , characterized in that a thickness (D) of the solid electrolyte layer ( 14 ) is in the range from 20 nm to 500 nm. 4 . The electrode material as claimed in claim 1 , characterized in that the recesses ( 16 ) or the recesses ( 16 ) and the solid electrolyte layer ( 14 ) are at least partly covered or coated with an electronically conductive material ( 18 ). 5 . The electrode material as claimed in claim 4 , characterized in that the electronically conductive material ( 18 ) is composed of carbon. 6 . The electrode material as claimed in claim 1 , characterized in that the recesses ( 16 ) or the recesses ( 16 ) and the solid electrolyte layer ( 14 ) are at least partly covered or coated with a mixture of an electronically conductive material ( 18 ) and a lithium-ion-conducting material ( 20 ). 7 . The electrode material as claimed in claim 1 , characterized in that the coated particles ( 10 , 10 ′, 10 ″) are embedded in a matrix ( 22 ) comprising a lithium-ion-conducting material. 8 . The electrode material as claimed in claim 1 , characterized in that the coated particles ( 10 ) are embedded in a matrix ( 22 ) composed of a composite material comprising a lithium-ion-conducting material and electronically conductive material. 9 . An electrode, comprising at least one electrode material as claimed in claim 1 . 10 . An electrochemical energy store, comprising an electrode as claimed in claim 9 . 11 . The electrode material as claimed in claim 4 , characterized in that the electronically conductive material ( 18 ) is selected from among carbon black, graphite or carbon nanotubes. 12 . A cathode, comprising at least one electrode material as claimed in claim 1 . 13 . A lithium ion cell, comprising an electrode as claimed in claim 9 .
