Abstract: New block polymer electrolytes have been developed which have higher conductivities than previously reported for other block copolymer electrolytes. The new materials are constructed of multiple blocks (>5) of relatively low domain size. The small domain size provides greater protection against formation of dendrites during cycling against lithium in an electrochemical cell, while the large total molecular weight insures poor long range alignment, which leads to higher conductivity. In addition to higher conductivity, these materials can be more easily synthesized because of reduced requirements on the purity level of the reagents.

Abstract: Disclosed are an electrolyte for a secondary battery, and a secondary battery including the same, the electrolyte including an electrolyte salt; an electrolyte solvent; and a compound generating heat through oxidation at voltages higher than drive voltage of a cathode, wherein the compound can decompose or evaporate electrolyte components by oxidation heat, thereby causing gas generation. Also, the compound is included in an internal pressure increase accelerant for a battery. Upon overcharge, since a compound subjected to oxidation at voltages higher than normal drive voltage of a cathode generates heat, electrolyte components can be decomposed or evaporated, thereby generating gas by the oxidation heat. Accordingly, it is possible to operate a safety means of a battery, without using an internal pressure increasing material directly generating gas through oxidation at overcharge voltage as the electrolyte additive, and thus to improve the overcharge safety of a secondary battery.

An electrochemical device may comprise solid state electrolytes with incorporated thin layers and/or particles of transition metal oxides, silicon, silicon oxide, or other suitable materials that will induce an increase in ionic conductivity of the electrolyte stack (for example, materials with which lithium is able to intercalate), or mixtures thereof. An improvement in ionic conductivity of the solid state electrolyte is expected which is proportional to the number of incorporated layers or a function of the distribution uniformity and density of the particles within the electrolyte. Embodiments of the present invention are applicable to solid state electrolytes in a broad range of electrochemical devices including thin film batteries, electrochromic devices and ultracapacitors.
