\nSilicon anodes are preferable over graphite anodes thanks to their higher (10X) energy density. However, silicon anodes have a tendency to degrade fairly quickly with the regular operation of a battery. This is particularly the case when silicon anodes are coupled with liquid electrolytes.
\nOn the other hand, solid-state batteries that use solid electrolytes in place of liquid also encounter problems. This is because such batteries use metallic lithium anodes which require storage at temperatures of up to 140 degrees Fahrenheit. This, in turn, means that such batteries are impractical in colder climates.
\nEngineers used the cheaper micro-silicon instead of the more favored nano-silicon
\nUC San Diego researchers also shared their findings in a press release. The team reportedly removed the carbon and binders found in silicon anodes. They also used the less expensive micro-silicon in favor of nano-silicon. Further, they replaced the liquid electrolyte with sulfide-based solid electrolytes.
\nThe results were quite illuminating, showing that solid electrolyte is \u201cextremely stable\u201d in batteries that use all-silicon anodes. It reportedly retained 80% capacity even after 500 charge\/discharge cycles at room temperature.
\nThe research paper\u2019s lead author, Darren H. S. Tan, said, \u201cThe solid-state silicon approach overcomes many limitations in conventional batteries. It presents exciting opportunities for us to meet market demands for higher volumetric energy, lowered costs, and safer batteries especially for grid energy storage.\u201d Tan is also the co-founder of startup UNIGRID Battery that has reportedly licensed this new battery technology.
\nMeanwhile, LG Energy Solution said that it will expand its research collaboration with UC San Diego. \u201cAs a leading battery manufacturer, LGES will continue its effort to foster state-of-the-art techniques in leading research of next-generation battery cells,\u201d said Myung-hwan Kim, Chief Procurement Officer at LG Energy Solution.
\nThis research could revolutionize electric vehicle production while also cutting down costs in the long run. We expect to learn more about this new technology in the months to come.
