Eriksson, R. 2015. Structural Changes in Lithium Battery Materials Induced by Aging or Usage. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1227. 75 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9165-9. Li-ion batteries have a huge potential for use in electrification of the transportation sector. The major challenge to be met...
A feasible and scalable two-step method is developed to synthesize LiFeSO4F(y)(OH)(1-y) which could deliver 92 and 80 mA h g(-1) when cycled at 1 C and 15 C, respectively. Moreover, with 80% of capacity retention after 2800 cycles at 1 C, this material should be of great interest as a contender to LiFePO4 for use in high power Li-ion batteries.
Polyatomic anion insertion electrodes present compositional and morphological variety, as well the ability to tune operational voltages by influencing nature of metal-oxygen bonding. Realising application these compounds in Li- Na-ion batteries requires a detailed understanding ion dynamics systems. Here is presented microscopic Li-ion diffusion properties LiFeSO4F Na2FePO4F, respectively, usin...
The choice of cathode material in Li-ion batteries underpins their overall performance. Discovering new materials is a slow process, and all major commercial are still based on those identified the 1990s. Discovery using high-throughput calculations has attracted great research interest; however, reliance databases existing begs question whether these approaches applicable for finding truly nov...
کاتد در باتری‌های لیتیم-یون مهمترین بخش و تعیین کننده کارآیی و رفتار این وسایل ذخیره انرژی می‌باشد. ماده کاتدی LiFeSO4F با ساختار تاووریت و گروه فضایی C2/c مورد بررسی نظریه تابعی چگالی (DFT) با استفاده از کد Wien2k قرار گرفت. محاسبات با استفاده از روش‌های GGA، GGA+U و PBE-Fock-α (از روش های Hybrid functionals، HF) انجام شدند. محاسبات ساختاری نشان داد این کاتد پس از خروج لیتیم پایداری خود را حفظ...
