摘要： Zinc electrolytic manganese dioxide (EMD) batteries including a high performing flexible chitosan-based gel electrolyte with poly-vinyl alcohol (PVA) and potassium hydroxide (KOH) additives were prepared. The Zn-EMD batteries were constructed using an optimized assembly technique employed to achieve good interfacial contact between the layers. Attaining energy densities between 150-250 Wh/kg (w.r.t cathode mass) is possible for these batteries, encouraging their use in wearable or flexible electronics. Using the chitosan-based gel electrolyte and limited voltage window testing, the prepared Zn-EMD alkaline batteries are among the best reported polymer-based alkaline electrolyte Zn rechargeable batteries.

摘要： An energy-efficient method of controlling the composite microstructure and resulting thermoelectric (TE) properties of TE composite films. The TE composite films, which include a small amount of naturally occurring chitosan binder that is sufficient to hold TE particles together, are modified by applying uniaxial mechanical pressure at low temperatures for a short duration. The TE composite films have high electrical conductivity and low thermal conductivity, making them ideal for use into high-performance energy harvesting thermoelectric devices.
