Roadmap for advanced aqueous batteries: From design of

The high capacity and low-voltage redox reactions of metals (except for Zn/Zn 2+) are out of the scope of the ESW of water, which cannot be directly used as anodes in aqueous electrolytes. Moreover, the dendrite formation and decrease in CE by side reactions are inherently unavoidable even in near-neutral electrolytes ( Fig. 1C ), especially for achieving a long-term life span.

Electrolysis of Sodium Chloride

Laser Scribing of High

2012/3/16Although electrochemical capacitors (ECs), also known as supercapacitors or ultracapacitors, charge and discharge faster than batteries, they are still limited by low energy densities and slow rate capabilities. We used a standard LightScribe DVD optical drive to do the direct laser reduction of graphite oxide films to graphene. The produced films are mechanically robust, show high electrical

The electrochemical treatment of graphite has been studied since the 1970s, when the production of graphite intercalation compound (GIC) was actively investigated. 6 – 9 When a higher voltage than GIC formation or a large current is applied, oxidation and expansion of graphite occur to generate graphite oxide. 10, 11 Graphite structure partially remains in graphite oxide; therefore, it is

Fundamental study on tin recovery in acidic aqueous

Tin is widely used in solder, tin plating and tin alloys. The current recovery rate of tin metal is low and insufficient with just over 300,000 tonnes annually. The grade of tin concentrates in traditional smelting methods needs to be at least 60%. Otherwise, iron, the chief impurity in tin concentrates can form tin-iron alloys and result in inefficient recovery of tin. Therefore, a
