Specific capacities of λ-MnO 2 cathodes and Na + -loaded melanin anodes were ∼80 and 30 mAhg −1 , respectively, as measured by half-cell discharge experiments (38). The maximum amount of melanin (21 mg) exhibits a theoretical 1:1 ratio of anode-cathode capacity.…”

Biodegradable electronics represents an attractive and emerging paradigm in medical devices by harnessing simultaneous advantages afforded by electronically active systems and obviating issues with chronic implants. Integrating practical energy sources that are compatible with the envisioned operation of transient devices is an unmet challenge for biodegradable electronics. Although high-performance energy storage systems offer a feasible solution, toxic materials and electrolytes present regulatory hurdles for use in temporary medical devices. Aqueous sodium-ion charge storage devices combined with biocompatible electrodes are ideal components to power next-generation biodegradable electronics. Here, we report the use of biologically derived organic electrodes composed of melanin pigments for use in energy storage devices. Melanins of natural (derived from Sepia officinalis) and synthetic origin are evaluated as anode materials in aqueous sodium-ion storage devices. Na

Sodium ion batteries are a topic of emerging interest, as the low cost and high natural abundance of sodium precursors provide a specific advantage over commercial lithium ion batteries. Comparatively, sodium chemistries suffer from lower operating voltages, making the development of suitable high voltage positive electrodes key to enabling sodium chemistries capable of direct replacement for modern lithium ion storage devices. Herein, we investigate dis/ordered nickel doped manganese spinels (Na x Mn 2-y Ni y O 4 ) as a positive electrode for sodium ion battery applications. Due to the kinetic limitations of the sodium de/insertion reaction into Na 1-x Mn 2-y Ni y O 4 the effect of both temperature and the electrochemical cycling window are studied revealing a unique reaction pathway and potential optimization routes for further study. Increasing interest in large-scale electrochemical energy storage for grid applications has prompted the investigation of battery chemistries that are more cost-effective as compared to commercial Li-ion technology. Due to the large abundance and associated low costs of sodium precursors, sodium-ion batteries have been widely investigated over recent years. Investigations into positive electrodes for sodium ion batteries (SIBs) have produced a number of different electrode chemistries capable of reversible Na + de/insertion. In particular, the manganese oxides have demonstrated a number of possible host structures suitable for reversible cycling of Na + , with the majority of attention being generally confined to layered compounds consisting of transition metal doped P2, P3, and O3 type structures. 1-4However, there still remain certain drawbacks in utilizing such SIBs for commercial applications, as reversible Na + de/insertion requires large open structures due to the physically larger ionic radii of Na + (∼1.0 Å) relative to that of Li + (0.59 Å). 5Of particular concern is the lower voltage of SIBs using traditional chemistries imparted by the Na/Na + redox, which is approximately 0.33 V higher than that of Li/Li + . Table I considers a competitive analysis of various cathode chemistries of potential interest for SIBs, and although suffering from a reduction in gravimetric and volumetric capacity when comparing against LIBs, movement from lithium to sodium chemistries offers considerable advantages in terms of cost and raw material abundance making them far more practical for electrical grid applications.Due to the large foundation of research on lithium-ion cathode materials, it is desirable to potentially utilize such promising structures for analogous cathodes in SIBs. The spinel structure has been widely studied, and offers facile Li + de/insertion by nature of the 3D interdiffusional pathways. However, the large ionic size differences between Li + and Na + have demonstrated considerable difficulty in the implementation of sodium analogues to existing Li-based compositions; yet the spinel structure has proven to successfully accommodate Na + following initial delithiation ...
