Al is an inexpensive, highly conducting material that is readily available in thin foils of high purity, and is the most widely studied and used positive electrode current collector for lithium batteries.
The electrode composed of 3 wt % C/Li 2 TiO 3 -coated LMP particles with carbon black and PVdF in the ratio 70:20:10 delivered capacities of 132 and 118 mAh g −1 at 0.5 C and 2 C, respectively, with a capacity retention of 93% after 240 cycles at 2C with the standard electrolyte (1 mol L −1 LiPF 6 in a 1:1 mixture of EC/DMC).
Cu is taken as the relative standard, because it is the most widely used material for the negative electrode current collector (at least in Li-ion cells). The following materials have been examined as positive current collectors in lithium batteries. For high voltage Li-ion cells, Al is the material of choice.
A Ni–Al–Si–C alloy with various trace elements and up to 10% of Mo, W, Nb, Zr was suggested as the positive electrode current collector of Li-ion cells. Lanthanides are included up to 0.5%, and other elements as required (all metallic except for Si and C). 110
Here, we report Li 3 TiCl 6 as positive electrode active material. With a discharge voltage close to that of LiFePO 4, it shows a high ionic conductivity of 1.04 mS cm –1 at 25 °C, and is easily compressible like most chlorides.
We also report the assembly and testing of a “single Li3TiCl6” cell where this chloride material is used as the solid electrolyte, negative electrode and positive electrode. An ideal positive electrode for all-solid-state Li batteries should be ionic conductive and compressible. However, this is not possible with state-of-the-art metal oxides.
