Terminal –OH group in PEO-based solid polymer electrolytes is the limiting factor of electrochemical stability window, replacing it with more stable groups can accelerate development high-voltage solid-state batteries.
The key bottleneck troubling the application of solid electrolyte is contradictory requirements from Li-metal and cathode, which need high modulus to block Li-dendrite penetration flexibility enable low interface resistance, respectively. This study describes a thin asymmetrical design address these shortcomings. In this architecture, rigid ceramic-layer modified with an ultrathin polymer toward accomplish dendrite-suppression Li-anode, soft polymer-layer spreads over exterior interior...
In response to the call for safer high-energy-density storage systems, high-voltage solid-state Li metal batteries have attracted extensive attention. Therefore, solid electrolytes are required be stable against both anode and cathodes; nevertheless, requirements still cannot completely satisfied. Herein, a heterogeneous multilayered electrolyte (HMSE) is proposed broaden electrochemical window of 0-5 V, through different electrode/electrolyte interfaces overcome interfacial instability...
A very simple, activation-free method for preparing nitrogen-doped porous carbon with high surface area supercapacitors by direct pyrolysis of a nitrogen-containing organic salt, ethylenediamine tetraacetic acid (EDTA) disodium magnesium in an inert atmosphere is presented. As the temperature increases from 500 to 900 °C, both BET and pore volume EDTA-derived carbons increase reach up 1811 m2 g−1 1.16 cm3 g−1, respectively, while nitrogen content decreases 11.14 at.% 1.13 at.%. The obtained...
A novel quinone–amine route is developed to fabricate N, O codoped carbon nanospheres for an all-solid-state supercapacitor with ultrahigh energy density.
Safety concerns are impeding the applications of lithium metal batteries. Flame-retardant electrolytes, such as organic phosphates electrolytes (OPEs), could intrinsically eliminate fire hazards and improve battery safety. However, OPEs show poor compatibility with Li though exact reason has yet to be identified. Here, plating process in Li/OPEs interface chemistry were investigated through ex situ techniques, cause for this incompatibility was revealed highly resistive inhomogeneous...
Garnet-type electrolytes suffer from unstable chemistry against air exposure, which generates contaminants on electrolyte surface and accounts for poor interfacial contact with the Li metal. Thermal treatment of garnet at >700 °C could remove contaminants, yet it regenerates in air, aggravates dendrite issue as more electron-conducting defective sites are exposed. In a departure removal approach, here we report new that converts into fluorinated interface moderate temperature <180 °C. The...
All-solid-state batteries (ASSBs) have gained considerable attention due to their inherent safety and high energy density. However, fabricating ultrathin freestanding solid electrolyte membranes for practical all-solid-state pouch cells remains challenging. In this work, polytetrafluoroethylene (PTFE) fibrilization was utilized interweave inorganic electrolytes (SEs) into membranes. Representative SE membranes, including Li6PS5Cl, Li3InCl6, Li6.5La3Zr1.5Ta0.5O12, demonstrate not only a...
Solid-state Li-S and Li-Se batteries are promising devices that can address the safety electrochemical stability issues arise from liquid-based systems. However, solid-state Li-Se/S usually present poor cycling due to high resistance interfaces decomposition of solid electrolytes caused by their narrow windows. Here, an integrated battery based on a halide Li3 HoCl6 electrolyte with ionic conductivity is presented. The intrinsic wide window its toward Se lithiated species effectively inhibit...
All-solid-state lithium-sulfur batteries offer a compelling opportunity for next-generation energy storage, due to their high theoretical density, low cost, and improved safety. However, widespread adoption is hindered by an inadequate understanding of discharge products. Using X-ray absorption spectroscopy time-of-flight secondary ion mass spectrometry, we reveal that the product all-solid-state not solely composed Li2S, but rather consists mixture Li2S Li2S2. Employing this insight,...
Abstract Constructing a 3D lithium metal anode has been demonstrated to be the most effective strategy address its dendrite issue in liquid batteries. However, this promising approach proved challenging inherit all‐solid‐state Li batteries (ASSLMBs) because of rigidity inorganic solid electrolytes (SEs), which constrains interfacial solid–solid ionic contact. Herein, is situ constructed for ASSLMBs by spontaneous chemical reactions between halide SEs and metal. The formed Li–Al alloys...
