This figure shows the measured charging capacity, discharging capacity, and coulombic efficiency of the aluminum-ion battery across 7,500 charge-discharge cycles. The fact that both charging and discharging capacity do not decline over the 7,500 cycles shown indicates that cycling does not cause the battery capacity to fade. The fact that coulombic efficiency is always close to 100 percent indicates most units of charge stored in the battery come back when the battery is discharged, and aren't consumed by side reactions or other processes.

Tis schematic shows how the aluminum-ion battery shuttles AlCl4- ions from its graphite cathode to its aluminum foam
Progress on a key front imo. Seeking Alpha article is a nice nod from the editorial staff at alpha. Steady she goes, take us out captain.
