The present invention relates to ion-conducting solvent-free polymeric systems characterized as being cationic single ion conductors. The solvent-free polymer electrolytes comprise a flexible polymer backbone to which is attached a metal salt, such as a lithium, sodium or potassium salt, of a sterically hindered phenol. The solid polymer electrolyte may be prepared either by (1) attaching the hindered phenol directly to a flexible polymeric backbone, followed by neutralization of the phenolic OH's or (2) reacting the hindered phenol with a polymer precursor which is then polymerized to form a flexible polymer having phenolic OH's which are subsequently neutralized. Preferably the hindered phenol-modified polymeric backbone contains a polyether segment. The ionic conductivity of these solvent-free polymer electrolytes has been measured to be in the range of 10.sup.-4 to 10.sup.-7 S cm.sup.-1 at room temperature.

摘要:
A refrigerant tank includes a base plate made of cooper and a reinforcing frame made of stainless steel. A block made of copper extends through the reinforcing frame and has one face in contact with the base plate and an opposite face in contact with a heating body. Heat generated by the heating body is transferred through the cooper block and through the copper base plate to refrigerant inside the refrigerant tank. The stainless steel reinforcing frame provides strength to the refrigerant tank to allow the heating body to be pressed against the heating tank.
