The ever-rising demands for energy dense electrochemical storage systems have been driving interests in beyond Li-ion batteries such as those based on lithium and magnesium metals. These high energy density batteries suffer from several challenges, several of which stem from the flammability/volatility of the electrolytes and/or instability of the electrolyte with either the negative, positive electrode or both. Recently, hydride-based electrolytes have been paving a path towards overcoming these issues. Namely, highly performing solid state electrolytes have been reported and several key challenges in multivalent batteries were overcome. In this review, the classes of hydride-based electrolytes reported for energy dense batteries are discussed. Future perspectives are presented to guide research directions in this field.

With high energy density, long cycle life and high voltage Lithium-ion batteries are one of very promising pollution-free power supply. The electrolytes for these batteries consist of flammable organic solvents which are serious hazard under abusive conditions especially for large-scale lithium batteries. To reduce flammability of electrolyte of lithium-ion batteries and resolve safety problem, Tris (2, 2, 2-trifluoroethyl) phosphate (TFP) was synthesized and added into electrolytes as additive. It was found that the SET decreased significantly with the increase of the concentration of TFP. When the concentration is over 20% (vol.) electrolytes are nonflammable. At the same time, with the concentration increasing, the ion-conductivity decreased and the discharge capacity also came down slowly. The electrochemistry stability of LiCoO2 cathode was improved. According to our study, it is possible to find a cosolvent or additive that makes nonflammable lithium-ion electrolyte be put into practice.

Abstract High energy density lithium-ion batteries are urgently needed due to the rapid growth demands of electric vehicles, electronic devices, and grid energy storage devices. There is still significant opportunity to improve the energy density of existing state-of-the-art lithium-ion batteries by optimizing the separator thickness, which is usually ignored. Here, the dependence of battery gravimetric and volumetric energy densities on separator thickness has been quantitatively discussed in different type Li-ion batteries by calculations combined with experiments. With a decrease in separator thickness, the volumetric energy density is greatly improved. Meanwhile, the gravimetric energy densities are significantly improved as the electrolyte soaking in the separator is reduced. The gravimetric and volumetric energy densities of graphite (Gr) | NCM523 cells enable to increase 11.5% and 29.7%, respectively, by reducing the thickness of separator from 25 μm to 7 μm. Furthermore, the Li | S battery exhibits an extremely high energy density of 664.2 Wh Kg-1 when the thickness of the separator is reduced to 1 μm. This work sheds fresh light on the rational design of high energy density lithium-ion batteries.
