AbstractThere is an urgent need for low-cost, high-energy-density, environmentally friendly energy storage devices to fulfill the rapidly increasing need for electrical energy storage. Multi-electron redox is considerably crucial for the development of high-energy-density cathodes. Here we present high-performance aqueous zinc–manganese batteries with reversible Mn2+/Mn4+ double redox. The active Mn4+ is generated in situ from the Mn2+-containing MnOx nanoparticles and electrolyte. Benefitting from the low crystallinity of the birnessite-type MnO2 as well as the electrolyte with Mn2+ additive, the MnOx cathode achieves an ultrahigh energy density with a peak of 845.1 Wh kg−1 and an ultralong lifespan of 1500 cycles. The combination of electrochemical measurements and material characterization reveals the reversible Mn2+/Mn4+ double redox (birnessite-type MnO2 ↔ monoclinic MnOOH and spinel ZnMn2O4 ↔ Mn2+ ions). The reversible Mn2+/Mn4+ double redox electrode reaction mechanism offers new opportunities for the design of low-cost, high-energy-density cathodes for advanced rechargeable aqueous batteries.

Implementing a low cost, power efficient and high performance routing protocol in wireless sensor networks (WSNs) is an important requirement for transmitting a packet through network. In this paper we propose, a new cost and energy aware routing protocol (CEAR) that works based on the two metrics such as cost welfare metric and route score metric.A hybrid electrical energy storage (HEES) framework which holds numerous banks of heterogeneous electrical energy storage (EES) components to be specific battery and a ultra-capacitor is used for providing energy to the network exhibit in the WSN for routing. The simulation results shows that our proposed routing protocol routes the packet efficiently by choosing the best path that also reduces the cost and routes the packet with reduced power consumption. The quantitative metrics in terms of packet delivery ratio of 0.93, average end to end delay of 110 secs, packet loss ratio of 0.75, average throughput attained of 250 bits/sec and efficiency of 98-99.9% overpowers the performance of our proposed work.

By collecting and analyzing relevant literature results, we demonstrate that the nanostructuring of polypyrrole (PPy) electrodes is a crucial strategy to achieve high performance and stability in energy devices such as fuel cells, lithium batteries and supercapacitors. In this critic and comprehensive review, we focus the attention on the electrochemical methods for deposition of PPy, nanostructures and potential applications, by analyzing the effect of different physico-chemical parameters, electro-oxidative conditions including template-based or template-free depositions and cathodic polymerization. Diverse interfaces and morphologies of polymer nanodeposits are also discussed.
