چکیده
Rechargeable alkaline battery is a potential high-powered next-generation electrochemical energy storage equipment. However, the inferior density, compare with other technologies, restrict its further practical applications. To address this, rational design and optimization of electrode significance. Herein, we demonstrate construction high density NiCo/Bi by controllable MOF hydrolysis. Specifically, hydrolysis conversion Bi-MOF into Bi2O3 performed on large scale for first time. The obtained flower-like present specific capacity, excellent rate capability stable cycles life. And series ex-situ characterizations were employed to trace phase transformation morphological changes in charge-discharge. Meanwhile, Ni/Co layered double hydroxide hierarchical microspheres also prepared via bimetallic Ni/Co-MOF. Furthermore, assembled NiCo//Bi based NiCo-LDH cathode anode perform 84.9 Wh/kg at 1600 W/kg, indicating

متن کاملA battery composed of a polypyrrole cathode and a magnesium alloy anode-Toward a bioelectric battery
A bioelectric battery can be implanted into the human body and relies on oxygen in the internal body fluid to produce electrical energy. In this work, a battery that uses polypyrrole doped with a biological polyelectrolyte (dextran sulfate, an anti-coagulant) as the cathode and bioresorbable Mg alloy (AZ61) as the anode was developed. This battery exhibited a discharge capacity of 565 mA h g-1 ...
