Special Issue Information

Dear Colleagues,

Existing battery technologies still face performance and cost challenges, including barriers in specific energy, energy density, service life, and charge efficiency at high rates, originating from the fundamental behavior of the active and inactive materials used. With all their benefits and drawbacks, electrolyte play a key, critical role in terms of design and control of electrode processes as well as regarding material interactions, performance, long-term stability, cost, and the safety of a battery. The chemistry of electrolytes and their interaction with anode and cathode materials is complex and yet not fully understood, thus representing a delicate balance of various properties. A systematic experimental approach allows understanding the structure–property–performance relationship and impact on the overall battery chemistry, thus enabling further tailoring of electrolyte properties for targeted application. Despite our limited knowledge, modern requirements for battery electrolytes call for development of sophisticated electrolyte solutions with multifunctional components, able to simultaneously fulfill several duties of vital importance as well as a profound understanding and elucidation of interfacial electrochemistry and processes. This can be regarded as a paradigm shift in order to increase the efficiency and safety of lithium-based and post-lithium-based batteries when compared with contemporary technologies.

Widening the working voltage of lithium-ion batteries is considered as an effective strategy to improve their energy density. However, the decomposition of conventional aprotic electrolytes at high voltage greatly impedes the success until the presence of high concentration electrolytes (HCEs) and the resultant localized HCEs (LHCEs). The unique solvated structure of HCEs/LHCEs endows the involved solvent with enhanced endurance toward high voltage while the LHCEs can simultaneously possess the decent viscosity for sufficient wettability to porous electrodes and separator. Nowadays, most LHCEs use LiFSI/LiTFSI as the salts and β-hydrofluoroethers as the counter solvents due to their good compatibility, yet the LHCE formula of cheap LiPF6 and high antioxidant α-hydrofluoroethers is seldom investigated. Here, we report a unique formula with 3 mol L−1 LiPF6 in mixed carbonate solvents and a counter solvent α-substituted fluorine compound (1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropylether). Compared to a conventional electrolyte, this formula enables dramatic improvement in the cycling performance of LiCoO2//graphite cells from approximately 150 cycles to 1000 cycles within the range of 2.9 to 4.5 V at 0.5 C. This work provides a new choice and scope to design functional LHCEs for high voltage systems. Full article
