“…The cost of this new electrolytic Zn–MnO 2 battery was estimated at <US$10 per kWh. This is significantly less than that for current Li‐ion batteries of US$300 per kWh, ZIBs (US$65 per kWh), Ni–Fe batteries (US$72 per kWh), and lead–acid batteries (US$48 per kWh) …”

Zinc‐based electrochemistry is attracting significant attention for practical energy storage owing to its uniqueness in terms of low cost and high safety. However, the grid‐scale application is plagued by limited output voltage and inadequate energy density when compared with more conventional Li‐ion batteries. Herein, we propose a latent high‐voltage MnO2 electrolysis process in a conventional Zn‐ion battery, and report a new electrolytic Zn–MnO2 system, via enabled proton and electron dynamics, that maximizes the electrolysis process. Compared with other Zn‐based electrochemical devices, this new electrolytic Zn–MnO2 battery has a record‐high output voltage of 1.95 V and an imposing gravimetric capacity of about 570 mAh g−1, together with a record energy density of approximately 409 Wh kg−1 when both anode and cathode active materials are taken into consideration. The cost was conservatively estimated at

Aqueous sodium-ion batteries (SIBs) represent a class of green electrochemical technology for large-scale storage of sustainable energies such as wind power and solar radiation, owing to their low cost, environmental friendliness, and reliable safety. However, there is still lack of available anode materials for aqueous SIBs. Herein, nanocrystal-assembled porous Na MgTi(PO ) aggregates are reported as novel anode material for aqueous SIBs. The crystal structure, morphological features, and electrochemical properties have been analyzed with X-ray diffraction, scanning electron microscopy, transition electron microscopy, cyclic voltammetry, and charge/discharge measurements. As revealed, the material possesses a porous nanostructure composed of 5 nm nanocrystals and mesoporous channels. During Na-insertion/extraction, it undergoes a one-step single-phase reaction mechanism through reversible electrochemistry of the Ti /Ti redox couple, showing a rechargeable capacity of 54 mAh g and an average working potential of -0.63 V (vs. Ag/AgCl) at 0.2 C. More importantly, good rate capacity (33 mAh g at 4 C) and excellent cycling performance (94.2 % capacity retention after 100 cycles at 0.5 C) are achieved due to the unique porous nanostructure and robust compositional framework. The finding in this work would create new opportunities for design of low-cost, long-cycling aqueous SIBs.
