Aqueous Li-ion battery enabled by halogen conversion–intercalation chemistry in graphite - lithium ion batteries for sale

Use of "water"in-
Salt' electrolyte greatly expands the electrochemical window of lithium water
The ion battery goes to 3 to 4 volts, making it high-
Voltage cathode with low level
Potential graphite anode 1,2, 3,4.
However, the limited capacity of the lithium plug-in layer (less than 200-
Hour per gram of typical transitionmetal-
The oxide cathode 5, 6 eliminates a higher energy density.
The negative oxidation-reduction reaction of Anionic al7, 8 or exclu9 9 can obtain a higher capacity, but at the cost of reversible.
Here, we report the chemical of the halogen generation conversion insertion layer that produces a composite electrode with a capacity of 243 in graphite-
Hours per gram with an average potential of 4 (total electrode weight ).
2 v vs Li/Li.
Experimental properties and modeling attribute this specific capacity to intensive stages-
I graphite insertion compound, c3. 5[Br0. 5Cl0.
5], can be formed reversibly in waterin-
Bisalt electrolyte.
By coupling the cathode with the passive graphite anode, we created a 4-volt-
Water-like Li-
Ion full battery with energy density of 460 W
The total number of hours per kilogram of composite electrodes and the efficiency of about 100 Cullen.
This anion conversion-insertion mechanism combines the high energy density of the conversion reaction, the excellent reversible properties of the insertion mechanism, and the improvement of the safety of the water battery.
