Phase-boundary regulation boosting electrochemical reactivity of tin-based anodes for magnesium-ion batteries

Relatively arduous alloying reaction and sluggish diffusion kinetics of Sn-based anodes limit their practical applications in magnesium ion batteries (MIBs). To deal with these dilemmas, a general strategy was proposed to regulate the electrochemical reactivity and performance of Sn-based anodes for Mg storage through the introduction of the second phase and phase boundary.

The biphase Sn–Al, Sn–Pb and Sn–ZnO films were further fabricated via magnetron co-sputtering. Taking Sn–Al as an example, it has been revealed that the introduction of Al can effectively stimulate the electrochemical reaction of Sn with Mg in either nanoscale or bulk through combining experiments with density-functional theory calculations. Specially, the rolled Sn–Al electrode exhibits superior long-term stability over 5000 cycles.

Additionally, the Mg-storage mechanism of the Sn–Al electrode was investigated by operando X-ray diffraction. The Sn–Al anodes also demonstrate good compatibility with simple Mg-salt-based electrolytes like Mg(TFSI)2 in full cells. More importantly, it has been authenticated that the activation effect of second phase and phase boundary to Sn is also applicable to Pb and ZnO. These findings may provide a favorable reference for the development of alloy-type anodes for MIBs.

  The ever-increasing demands for advanced lithium-ion batteries have greatly stimulated the quest for robust electrodes with a high areal capacity. Producing thick electrodes from a high-performance active material would maximize this parameter. However, above a critical thickness, solution-processed films typically encounter…

Despite the many potential applications of seawater batteries (SWBs), the limited performance of available materials has hindered their commercialization. To tackle this issue, scientists have developed a novel co-doped carbon material for the anode of SWBs. Their straightforward synthesis route and the high performance of the developed anode material will pave the way for the widespread adoption of SWBs, which are safer and less expensive than lithium-ion batteries.

Lithium-ion batteries have taken the world by storm thanks to their remarkable properties. However, the scarcity and high cost of lithium has led researchers to look for alternative types of rechargeable batteries made using more abundant materials, such as sodium. One particularly promising type of sodium-based battery is seawater batteries (SWBs), which use seawater as the cathode.

Though SWBs are environmentally benign and naturally firesafe, the development of high-performance anode materials at a reasonable cost remains a major bottleneck that prevents commercialization. Traditional carbon-based materials are an attractive and cost-efficient option, but they have to be co-doped with multiple elements, such as nitrogen (N) and sulfur (S), to boost their performance up to par. Unfortunately, currently known synthesis routes for co-doping are complex, potentially dangerous, and don't even yield acceptable doping levels.

New hard-carbon anode material for sodium-ion batteries will solve the lithium conundrum

Cost-effective rechargeable batteries are at the heart of virtually all portable electronic devices, which have become ubiquitous in modern daily life. Moreover, rechargeable batteries are essential components in many environment-friendly technologies, such as electric cars and systems that harvest renewable energy. They are also key enablers of various medical devices and facilitate research in various fields as the energy source of electronic sensors and cameras. So, it shouldn't come as a surprise that there is a lot of effort spent in developing better and cheaper rechargeable batteries.

So far, rechargeable lithium-ion batteries hold the number-one spot thanks to their great performance across the board in terms of capacity, stability, price, and charging time. However, lithium, and other minor and costly metals like cobalt and copper, are not among the most abundant materials on the earth's crust, and their ever-increasing demand will soon lead to supply problems around the world. At the Tokyo University of Science, Japan, Professor Shinichi Komaba and colleagues have been striving to find a solution to this worsening conundrum by developing rechargeable batteries using alternative, more abundant materials.
