“…The characteristic bands of PPy can be observed at 1,550-1,650 cm −1 (C=C stretching vibration of doped PPy ring), 1,400 cm −1 (C-N stretching mode of doped PPy), 1,336 cm −1 (C-H or C-N inplane deformation modes), 2,365 cm −1 (overtones and combinations of CH 2 and NH 2 stretching and wagging vibrations), and around 3,431 cm −1 (N-H and C-H stretching vibrations). Admixing of PPy with LiNi 1/3 Mn 1/3 Co 1/3 O 2 cathode would reduce the particle-to-particle separation and also resistance which significantly enhances the electrical conductivity of the composites [26].…”

“…PPy is very insoluble in aqueous electrolytes 26 . Its electrochemical cycling proceeds by a p-type doping/de-doping process: Anions from the electrolyte coordinate to the PPy chains during oxidation, and they are released during reduction 27 . The reduction and oxidation of the polymer could also be balanced by smaller ions, such as H 3 O + in acidic aqueous electrolytes, which can fit into the existing paracrystalline lattice as previously demonstrated in the case of poly(3,4-ethylenedioxythiophene) 28 .…”

“…2a). A PPy anode was recently paired with LiCoO 2 in an aqueous lithium-ion battery, but its low electronic conductivity upon reduction severely limited the rate capability, energy efficiency and cycle life of the cell 27 . Although it has a high theoretical specific capacity of 82 mAh g − 1 (ref.…”

A high-rate and long cycle life aqueous electrolyte battery for grid-scale energy storage

new types of energy storage are needed in conjunction with the deployment of solar, wind and other volatile renewable energy sources and their integration with the electric grid. no existing energy storage technology can economically provide the power, cycle life and energy efficiency needed to respond to the costly short-term transients that arise from renewables and other aspects of grid operation. Here we demonstrate a new type of safe, fast, inexpensive, long-life aqueous electrolyte battery, which relies on the insertion of potassium ions into a copper hexacyanoferrate cathode and a novel activated carbon/polypyrrole hybrid anode. The cathode reacts rapidly with very little hysteresis. The hybrid anode uses an electrochemically active additive to tune its potential. This high-rate, high-efficiency cell has a 95% round-trip energy efficiency when cycled at a 5C rate, and a 79% energy efficiency at 50C. It also has zero-capacity loss after 1,000 deep-discharge cycles.

Ever-rising energy demand, fossil fuel dependence, and climate issues have harmful consequences to the society. Exploring clean and renewable energy to diversify the world energy matrix has become an urgent matter. Less explored or unexplored renewable energy sources like the salinity and proton gradient energy are an attractive alternative with great energy potential. This paper discusses important electrochemical systems for energy conversion from natural and artificial concentration gradients, namely capacitive mixing (CapMix), mixing entropy batteries (MEB), and neutralization batteries (NB); the working principle and thermodynamic formalism of these systems; and the materials employed in the assembly of these systems.
