Abstract
Methods of reducing acid stratification with an acid-soluble and acid-stable polymer with a high molecular weight are disclosed herein. Electrolytes and separators for an energy storage device are disclosed herein. The separator includes a coating containing an acid-soluble and acid-stable polymer with a high molecular weight. The electrolyte includes sulfuric acid and an acid-soluble and acid-stable polymer with a high molecular weight. Methods of making the separators disclosed herein and methods of making batteries are also disclosed herein.
Claims20
A battery separator comprising first and second major surfaces, wherein the battery separator further comprises an acid-soluble and acid-stable polymer, the acid-soluble and acid-stable polymer being configured to at least partially dissolve in an electrolyte of a battery to thereby increase the viscosity of the electrolyte.
A method of reducing acid stratification in a battery, the method comprising:
- introducing a battery separator comprising first and second major surfaces into an electrolyte of a battery, wherein the battery separator comprises an acid-soluble and acid-stable polymer that is configured to at least partially dissolve in the electrolyte to thereby increase the viscosity of the electrolyte.
A method of making a battery separator, comprising:
- applying to a battery separator a coating including an acid-soluble and acid-stable polymer, wherein the acid-soluble and acid-stable polymer is configured to at least partially dissolve in an electrolyte to thereby increase the viscosity of the electrolyte.
