An electricity-driven mobility circular economy with lifecycle carbon footprints for climate-adaptive carbon neutrality transformation.

Under the carbon neutrality targets and sustainable development goals, emergingly increasing needs for batteries are in buildings and electric vehicles. However, embodied carbon emissions impose dialectical viewpoints on whether the electrochemical battery is environmentally friendly or not. In this research, a community with energy paradigm shifting towards decentralization, renewable and sustainability is studied, with multi-directional Vehicle-to-Everything (V2X) and lifecycle battery circular economy.

Progressive "Layer to Hybrid Spinel/Layer" Phase Evolution with Proton and Zn Co-intercalation to Enable High Performance of MnO-Based Aqueous Batteries.

Manganese oxides are promising host materials in rechargeable aqueous batteries due to their low cost and high capacity; however, their practical applications have long been restricted by their sluggish reaction kinetics and poor cycling stability. Herein, the layered KHMnO·0.28HO (K36) with a proton and Zn cointercalation mechanism leads to a progressive phase evolution from layer-type K36 to hybrid layer-type KHZnMnO·HO and spinel-type ZnMnO nanocrystal after a long-term cycle.

Preintercalation Strategy in Manganese Oxides for Electrochemical Energy Storage: Review and Prospects.

Manganese oxides (MnO ) are promising cathode materials for various kinds of battery applications, including Li-ion, Na-ion, Mg-ion, and Zn-ion batteries, etc., due to their low-cost and high-capacity. However, the practical application of MnO cathodes has been restricted by some critical issues including low electronic conductivity, low utilization of discharge depth, sluggish diffusion kinetics, and structural instability upon cycling.

Boosting the Energy Density of Aqueous Batteries via Facile Grotthuss Proton Transport.

The recent developments in rechargeable aqueous batteries have witnessed a burgeoning interest in the mechanism of proton transport in the cathode materials. Herein, for the first time, we report the Grotthuss proton transport mechanism in α-MnO which features wide [2×2] tunnels. Exemplified by the substitution doping of Ni (≈5 at.
