The rapidly growing demand for energy storage has led to an increasing interest in advanced batteries. Aqueous-based rechargeable zinc-ion batteries have attracted considerable attention owing their low cost, good safety, and environmental friendliness. MnO2 is a promising cathode material zinc ion batteries; however, its application severely restricted because of poor electrical conductivity manganese dissolution. Herein, nitrogen-doped layered δ-manganese dioxide coated on carbon cloth...
A novel 3D MoS<sub>2</sub>@Fe<sub>3</sub>O<sub>4</sub> nanohybrid, composed of tubular MoS<sub>2</sub> uniformly and densely decorated with particulate Fe<sub>3</sub>O<sub>4</sub>, is constructed, which exhibits significantly improved lithium storage performances through an impressive synergistic interplay between the two active materials.
Abstract V 2 O 5 is a promising cathode material for lithium‐ion batteries owing to its extremely high theoretical capacity (440 mA h g −1 when storing 3 Li + ions and 294 ). However, drawbacks such as strong inclination aggregate the low conductivity inherent nanostructured drastically deteriorate cycle rate performances. Hence, hybridizing it with conductive matrix (e.g. graphene) improved electrochemical performance an interesting concept. It well established that heteroatom...

Methyl 1H-1,2,4-triazole-3-carboxylate (MTC) was added into lithium metal batteries as an electrolyte additive, and not only did this addition lead to formation of solid interfaces protect both the anode cathode, but MTC also served a Lewis base in removing HF from prevent deteriorating. Therefore, MTC, appropriate amount, can be very effective at improving electrochemical performance batteries.
In this study, 2-fluoro-5-iodopyridine (2-F-5-IPy) was used as an electrolyte additive, which can not only protect the negative electrode effectively by forming a stable SEI, but also convert dead lithium into active lithium. Benefits from are capacity retention of Li‖LiFePO4 cell after 300 cycles 36.5% to 89.4%, and symmetrical work stably for more than 800 hours. Therefore, addition 2-F-5-IPy improve performance metal batteries.
