Abstract
A device includes an ion-conducting membrane with ion-conducting ceramic particles, and an ion-conducting polymer that surrounds the ion-conducting membrane. The ion-conducting polymer includes a pressure-deformable film with a glass transition temperature lower than an operation temperature of the device.
Claims16
A method for making an energy storage device, the method comprising:
- dipping an ion-conducting membrane comprising ion-conducting ceramic particles retained in an insulating polymeric binder into a pre-polymer mixture of an ion-conducting polymer, wherein the ion-conducting ceramic particles have a top part and a bottom part that are not covered by the insulating polymeric binder and the pre-polymer mixture comprises polymerizable compounds, a compound that releases Li-ions, a polymerization initiator, and an optional ionic liquid;
- polymerizing the pre-polymer mixture under curing conditions when it is on the ion-conducting membrane to form an ion-conducting polymer;
- and
- assembling a resulting free-standing solid electrolyte with electrodes to form an energy storage device.
