Special Issue Information

Dear Colleagues,

It is well recognized that electrochemical energy storage systems could do much to significantly reduce global carbon dioxide emissions by simplifying the integration of intermittent wind and solar renewables into the electrical grid. Over the past two decades, conventional lithium based batteries as the most attractive electrical energy storage system have been significantly improved in terms of energy density, lifetime and cost. However, their relatively low gravimetric energy density, the flammability of the electrolytes together with the depletion of global lithium resources have limited the performance of these batteries. This has motivated researchers to develop safer, more efficient and durable alternative (both the chemistry and the configuration) batteries that have the potential to address the electrical energy storage demand in the future. Many of these new potential batteries are still under development and they deserve special attention. Therefore, this Special Issue, “Future Battery Concepts”, will gather researchers who are developing alternative batteries together to pave the way for future research. Prospective authors are invited to submit their original research as well as review/prospective articles for publication in this Special Issue. Potential topics include, but are not limited to:

  • Next generation lithium-ion batteries
  • Other ion-based batteries (Na, K, Mg, Al, etc. batteries)
  • Flow batteries
  • Biobatteries
  • Thermal batteries
  • Graphene batteries
  • Supercapacitors
  • Other emerging batteries

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Batteries is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Cost-effective methods need to be developed to lower the price of Na-ion battery (NIB) materials. This paper reports a proof-of-concept study of using a novel approach to the glycine-nitrate process (GNP) to synthesize sodium vanadium phosphate (Na3V2(PO4)3 or NVP) materials with both high-energy (102 mAh g−1 at C/20) and high-power characteristics (60 mAh g−1 at 20 C). Glucose-derived hard carbons (GDHCs) were optimized to reduce both sloping and irreversible capacity. The best results were achieved for electrodes with active material heat treated at 1400 °C and reduced Super P additive. Sloping region capacity 90 mAh g−1, irreversible capacity 47 mAh g−1, discharge capacity 272 mAh g−1 (of which plateau 155 mAh g−1) and 1st cycle coulombic efficiency (CE) 85% were demonstrated. GDHC||NVP full cell achieved 80 mAh g−1 (reversible) by NVP mass out of which 60 mAh g−1 was the plateau (3.4 V) region capacity. Full cell specific energy and energy density reached 189 Wh kg−1 and 104 Wh dm−3, respectively. After 80 cycles, including rate testing from C/20 to 10 C, the cell cycled at 65 mAh g−1 with 99.7% CE. With further optimization, this method can have very high industrial potential. Full article
