SOLID MATERIAL-/GEL ELECTROLYTE ACCUMULATOR WITH BINDER OF INORGANIC-ORGANIC HYBRID POLYMER AND METHOD FOR THE PRODUCTION THEREOF

摘要

The present invention relates to a lithium accumulator or a combination thereof with a double-layer capacitor which is distinguished by a solid material- or gel electrolyte and a binder made of inorganic-organic hybrid polymer. By means of the new binder concept presented here, it is possible to revolutionise the contacting of the individual components in these accumulators and thus to enable a fundamental improvement in the ion transport. Associated therewith is a new, fast, simple and flexible production method for lithium accumulators which optimises these with respect to safety, stability, environmental friendliness and efficiency.

主权项

1. A rechargeable lithium battery, comprising
a) at least two electrodes, at least one of said two electrodes comprising a material selected from the group consisting of lithium-intercalating/-deintercalating substances and electrically conductive substances, and mixtures thereof; b) at least one solid material- and/or gel electrolyte which is disposed between the at least two electrodes; and c) at least one Li-ion-conducting binder with or without lithium salt which contacts the electrode material and/or the solid material- and/or gel electrolyte, wherein the binder comprises a lithium-ion-conductive,inorganic-organic hybrid polymer, the solid material electrolyte consisting of particles which comprise Li-ion-conducting solid materials, and the gel electrolyte comprising Li-ion-conducting gels, and the electrode material comprising particles.
