ANODE FOR ZINC BASED BATTERIES CHALLENGES

The energy storage prospects of zinc batteries

Zinc ion batteries (ZIBs) that use Zn metal as anode have emerged as promising candidates in the race to develop practical and cost-effective grid-scale energy storage systems. 2 ZIBs have potential to rival and even surpass LIBs and LABs for grid scale energy storage in two key aspects: i) earth abundance of Zn, ensuring a stable and affordable raw material source, and ii) high safety that is associated with the utilization of aqueous-based electrolytes and non-toxic Zn metal anode. 3 While LIBs hold great advantages in terms of their high working voltage and low self-discharge rate, the improvements for overall performance of ZIBs rely heavily on intensive studies.

Hard carbon anode energy storage

In particular, inorganic anode materials such as Sn, metallic selenides, and hybrid materials have gained recognition as promising candidates for SIBs. 6 Among the carbonaceous materials, hard carbons are considered one of the most promising solutions for anode materials in SIBs due, among others, to their turbostratic structure, providing a high volume of closed porosity. 7 The exploitation of hard carbons as anode materials in SIBs has shown promising electrochemical energy storage performance, reaching specific capacity values of more than 300 mA h g −1 with a long plateau close to sodium's reduction potential.
