Special Issue Information

Dear Colleagues,

Designing qualified electrolytes and electrodes is key to the success of emerging battery systems. Electrode materials play an important role in the energy density, power density, and cycling life of batteries, and the design of reasonable electrode materials is essential to promote the development of novel battery technologies. As the only component that interfaces with every other component in the batteries, the electrolyte must simultaneously satisfy several criteria, including rapid ion and mass transportation, effective electron insulation, and electrochemical inertness. The associated electrolyte–electrode interfacing chemistry is the essence of electrolyte engineering, dictating the power, energy, and reversibility of the battery during its entire service life. This Special Issue will cover the key topics in next-generation “beyond Li-ion” battery technologies, including electrolytes, electrodes, and interphases.

Topics of interest include, but are not limited to, the following:

  • Novel battery systems;
  • Novel anode and cathode materials;
  • Li/Na/K/Zn metal anode;
  • Catalysts design for electrolytic water systems, fuel cells, Li-O2 batteries, etc.;
  • Electrolyte adjustment;
  • All-solid-state electrolyte design and batteries;
  • Solid electrolyte interface;
  • Electrochemical principles;
  • Failure mechanism of batteries.
  • Full batteries.

Abstract
This work investigates the stability of electrolyte systems used in sodium-ion-based batteries. The electrolytes consist of a 1:1 (v:v) mixture of ethylene carbonate (EC) and propylene carbonate (PC), a sodium-conducting salt (either NaPF6 or NaTFSI), and fluoroethylene carbonate [...] Read more.
This work investigates the stability of electrolyte systems used in sodium-ion-based batteries. The electrolytes consist of a 1:1 (v:v) mixture of ethylene carbonate (EC) and propylene carbonate (PC), a sodium-conducting salt (either NaPF6 or NaTFSI), and fluoroethylene carbonate (FEC), respectively, sodium difluoro(oxalato) borate (NaDFOB), as additives. Through systematic evaluation using gas chromatography coupled with mass spectrometry (GC-MS), we analyze the formation of degradation products under different conditions including variations in temperature, vial material, and the presence or absence of sodium metal. Our results reveal the significant influence of the conductive salt’s source on degradation. Furthermore, we observe that FEC’s stability is affected by the storage temperature, vial material, and presence of sodium metal, suggesting its active involvement in the degradation process. Additionally, our results highlight the role of NaDFOB as an additive in mitigating degradation. The study provides crucial insights into the complex network of degradation reactions occurring within the electrolyte, thus informing strategies for improved electrolyte systems in sodium-based batteries. Since the production, material selection and storage of electrolytes are often insufficiently described, we provide here an insight into the different behavior of electrolytes for Na-ion batteries.

Alloying-type anode materials have considerably promoted the development of potassium-ion batteries (PIBs) and sodium-ion batteries (SIBs), enabling them to achieve high-energy-density. However, large volume expansion and sluggish dynamic behavior have become key issues affecting electrochemical performance. Herein, bismuth (Bi) nano-rods are anchored on reduced graphene (rGO) and encapsulated via N-doped C (NC) to construct Bi@rGO@NC architecture as anode materials for SIBs and PIBs. The hierarchical confinement effect of three-dimensional conductive networks can not only improve electrode stability upon cycling via suppressing the large volume variation, but also eliminate the band gap of Bi and accelerate ion diffusion, thereby exhibiting favorable electrochemical reaction kinetics. Thus, Bi@rGO@NC contributes an ultra-long lifetime, over 1000 cycles, and an outstanding rate property to SIBs and PIBs. This work can pave the way for the construction of high-performance alloying-type anode materials for SIBs and PIBs. Full article
