What if our assumptions prove wrong? How willing are we to at least examine closely-held beliefs and accept a new, scientific finding? Sandia engineers are demonstrating that solid-state batteries containing a little liquid electrolyte can be safer than conventional lithium-ion cells. PV Buzz included a great executive summary in their article on the findings: A new study tackled a long-held assumption that adding some liquid electrolyte to improve performance would make solid-state batteries unsafe. Instead, the research team found that in many cases solid-state batteries with a little liquid electrolyte were safer than their lithium-ion counterparts. They also found, if the battery were to short-circuit, releasing all its stored energy, the theoretically super-safe, all-solid-state battery could put out a dangerous amount of heat. Those three points seem to contradict the conventional wisdom that eliminating electrolytes would lead to safer, less flammable batteries. Sandia engineers Alex Bates and John Hewson have published findings challenging that conventional wisdom in the peer-reviewed journal …
