Stable Li metal anode with protected interface for high-performance Li metal batteries

Correlating Structure and Properties of Super‐Concentrated Electrolyte Solutions: 17O NMR and Electrochemical Characterization

“…Several efforts have been devoting to understand the reason of an irregular deposition of Li during the charge process and to find strategies to obtain a homogeneous plating. Electrolyte additives able to create a selective inorganic/organic protective layer on Li or the use of novel electrolytes were proposed to stabilize the surface with a tailored SEI …”

“…Electrolyte additives able to create a selective inorganic/organic protective layer on Li or the use of novel electrolytes were proposed to stabilize the surface with a tailored SEI. [10][11][12] In order to deeply investigate the processes occurring in the novel electrochemical energy storage systems based on lithium metal anode, the combination of electrochemical techniques with bulk and advanced spectroscopic ones is mandatory. In this context, nuclear magnetic resonance (NMR) spectroscopy plays a key role to understand the processes taking place in a battery.…”

Three dimensional Ti3C2 MXene nanoribbon frameworks with uniform potassiophilic sites for the dendrite-free potassium metal anodes

“…S10, ESI †), indicative of the exceptional potassiophilicity of the a-Ti 3 C 2 MXene nanoribbons. 41,42 In addition, symmetric batteries based on a-Ti 3 C 2 -K and pure K were assembled to evaluate the K plating/stripping behavior. Unlike the bare K symmetric battery, the overpotential increased sharply to 2.0 V over 20 h due to the formation of K dendrites, while the a-Ti 3 C 2 -K battery showed a at and stable voltage hysteresis ($14 mV) for 110 h at 3 mA cm À2 for 1 h (Fig.…”

ZnCo2O4/ZnO induced lithium deposition in multi-scaled carbon/nickel frameworks for dendrite-free lithium metal anode

“…The common solution is constructing a hybrid lithium anode with homogeneous frameworks that can provide a host for lithium storing. A lot of materials have been explored as potential lithium host like carbon fibers [33][34][35][36] , graphene frameworks [37] , biomass derived carbon hosts [38][39][40][41] , organic/inorganic vertical nanochannels [42,43] , 3D metal skeletons [44,45] . Notably, the current densities flowing through the frameworks partly determine the critical time of dendrite growth according to Sand's Equation concerning Sand's time for dendrite growth model, thus the electronic conductive 3D metal framework has the advantage of reducing effective current densities and homogenizing charge transference at the interface, which is also expected to be an indispensable component for composite lithium metal anode [46] .…”
