Wax And Soap May Be Key To Better Rechargeable Batteries

Rechargeable batteries are not all that great yet. In fact, in a question posted to Pablo Paster in our "Ask Pablo" series, the inquiry wasn't which rechargeable batteries to use, but "Why do rechargeable batteries suck?" But researchers are working on ways to improve them so they last longer per charge and have more recharge cycles in their lifespan, without increasing the cost or complexity of the batteries. And it seems, simple wax and soap could hold just the solution.
