- The development of materials for clean energy.
- Wanted the devices’ battery to last for an indefinite period.
- Importance of safety of batteries that are currently being faced by many of us.
“The electrolyte in such batteries, typically a liquid organic solvent whose function is to transport charged particles from one of a battery’s two electrodes to the other during charging and discharging — has been responsible for the overheating and fires that, for example, resulted in a temporary grounding of all of Boeing’s 787 Dreamliner jets,” one of the researcher explains.
“The initial findings focused on a class of materials known as superionic lithium-ion conductors, which are compounds of lithium, germanium, phosphorus, and sulfur, but the principles derived from this research could lead to even more effective materials” the team says.
“With a solid-state electrolyte, there’s virtually no degradation reactions left” — meaning such batteries could last through “hundreds of thousands of cycles.”
