Alloy anode materials in lithium batteries usually suffer from fatal structural degradation due to the large volume change during cycling. Here the authors report a design in which Al foil serves as both anode and current collector to circumvent the strain.
The consequences of aluminium corrosion can be observed as a contributing part to the complex ageing phenomena during battery lifespan. Normally, the degradation of the Al current collector results in fading of the main battery parameters (i.e. capacity, energy density and Coulomb and energy efficiency) and increase of the electrical impedance.
However, the corrosion of Al is still observed under high voltages, and HF may have an adverse effect on the electrochemical cycling performance of lithium batteries. The Al corrosion can also be attenuated in the presence of another inorganic additive, i.e., fumed silica nanoparticles.
When graphene-coated Al foils are used as current collectors, their thinner thickness, superior adhesion, higher electronic conductivity, and Al corrosion inhibiting property synergistically improve overall performance of lithium batteries [ 201].
Conclusions and outlook Corrosion and anodic dissolution of aluminium current collectors in lithium-ion batteries are ongoing issues for researchers, manufacturers, and consumers. The inevitable adverse consequences of these phenomena are shortening of battery lifetime, reduction of the capacity and power, and accelerated self-discharge.
