SK On develops polymer electrolyte for lithium metal batteries in collaboration with University of Texas - Korean report

SK Onco, a major battery manufacturer, announced that it has developed an electrolyte called "SIPE" together with a research team led by Professor Hadi Kani, a student of Professor Goodenough at the University of Texas.
Professor Goodenough is a pioneer in battery research who doubled the capacity of the lithium Eon battery. He was awarded the Nobel Prize in Chemistry in 2019.
In order to realize the lithium metal battery, he has been working with SK On to develop a solid electrolyte. After passing away in June 2023, his student Professor Hadi is leading the research team.
"SIPE" improves Eon conductivity and lithium Eon conductivity. Compared to existing polymer electrolytes, it has improved Eon conductivity at room temperature by about 10 times and lithium Eon conductivity.
The conductivity has been increased by nearly five times. Eon Conductivity and Lithium Increasing the conductivity of Eon also improves the battery's output and charging performance.
Lithium metal batteries use metallic lithium in the negative electrode to
Although it can significantly increase the energy density, it is essential to suppress dendrites that reduce the charge/discharge efficiency in order to commercialize it. "SIPE" enhances the safety of the solid electrolyte interface and suppresses dendrites.
In addition, it has high mechanical durability, making it possible to produce large quantities. It has excellent thermal safety and can withstand high temperatures of over 250 degrees. It is expected to improve charging speed and performance at low temperatures.
I can wait.
