| abstract |
This invention is a new solid polymer ionically-conducting electrolyte material or composition (SPE) in which the mobile ions include, but are not limited to the lithium ion. SPEs of this invention are formed from the combination of three component materials comprising: (1) an ionic liquid as defined herein, (2) a lithium salt and (3) a polyalkene oxide or polyether material. The invention is useable with numerous types of electrochemical devices, especially rechargeable batteries. |
