The use of an alkali-metal anode (lithium, sodium or potassium) â" which isnâ(TM)t possible with conventional batteries â" increases the energy density of a cathode and delivers a long cycle life. In experiments, the researchersâ(TM) cells have demonstrated more than 1,200 cycles with low cell resistance.
Additionally, because the solid-glass electrolytes can operate, or have high conductivity, at -20 degrees Celsius, this type of battery in a car could perform well in subzero degree weather. This is the first all-solid-state battery cell that can operate under 60 degree Celsius.
Braga began developing solid-glass electrolytes with colleagues while she was at the University of Porto in Portugal. About two years ago, she began collaborating with Goodenough and researcher Andrew J. Murchison at UT Austin. Braga said that Goodenough brought an understanding of the composition and properties of the solid-glass electrolytes that resulted in a new version of the electrolytes that is now patented through the UT Austin Office of Technology Commercialization. The engineersâ(TM) glass electrolytes allow them to plate and strip alkali metals on both the cathode and the anode side without dendrites, which simplifies battery cell fabrication.
Another advantage is that the battery cells can be made from earth-friendly materials.
âoeThe glass electrolytes allow for the substitution of low-cost sodium for lithium. Sodium is extracted from seawater that is widely available,â Braga said.
They genuinely believe that the right to bear arms is a good thing and the deaths that result, while tragic, are the price of freedom.
Freedom is messy but then again so is life. Shall we get rid of automobiles? People genuinely believe their right to own a car is a good thing and the deaths from accidents and environmental destruction, while tragic, are the price of convenience.
If God had not given us sticky tape, it would have been necessary to invent it.
