2. Overview What is MXene? MXene and MXene/Sn synthesis
Characterization of materials
Results

3. MXene Precursor comes from a variety of MAX powders
M=Metal, A=Aluminum, X=Carbon, Nitrogen, Etc.
Max Powder is layers of MX and aluminum
When aluminum is exfoliated, MXene is formed
MXene used=Ti3C2

4. MXene Synthesis MAX powder is etched HF, exfoliating aluminum layers
After washing many times through centrifugation, MXene layers are closely packed
MXene is mixed with ethylene glycol and ultra-sonicated for 7+ hours

5. MXene/Sn Synthesis Tin chloride is stirred with MXene solution
Sample is placed in autoclave at high temperatures creating hydrothermal growth of tin nanoparticles within MXene layers
Once washed and dried, a slurry can be prepared to be made into an electrode

6. Characterization
MXene/Sn
MXene

7. Results
Specific capacitance was ~500 mAh/g after 90+ cycles
