High Energy Density of Ball-Milled Fluorinated Carbon Nanofibers as Cathode in Primary Lithium Batteries

“…Because fluorinated carbons (CFxs) exhibit the highest theoretical energy density among current cathode materials for lithium primary batteries, extensive efforts are devoted to the enhancement of either their energy density, their power density, or both (see recent review papers [ 1 , 2 , 3 , 4 ]). The very recent strategies involve (i) considering new carbonaceous precursors for fluorination or innovative fluorination routes [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ], (ii) chemical changes in the CFx, either on the surface or in the bulk [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ], and (iii) change in the electrolyte composition [ 13 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Ball milling, a simple process for reducing the particle size of a compound, is widely used for electrode materials [ 30 , 31 , 32 , 33 , 34 ], creating more space to accumulate the LiF(s) particles formed.…”

From CO2 to Formic Acid Fuel Cells

“…To sink CO 2 resulting from fossil fuel combustion, the first stage is CO 2 capture , and then either its storage or conversion to fuels and chemicals. − A more or less appropriate approach to decrease CO 2 emissions depends on the sector and follow technological trends . For instance, in the transportation sector, electrification through plug-in hybrid electric vehicles (PHEVs) and plug-in electric vehicles (PEVs) equipped with efficient Li-ion batteries , seems a viable option. In the electric power sector, renewable energy feeding smart electricity grids in distributed energy generation (DEG) systems has the potential to replace traditional electricity power plants and decrease CO 2 emissions .…”
