“…While Li 2 CO 3 is known to provide high ionic conductivity, [22,30,31] LiF may provide high mechanical strength, elasticity, [22,32,33] and low solubility [34] but resistive. [17,18,33,35] Given that XPS analysis results on individual additive (Figure S10, Supporting Information), the roles of IF-CE are found as first to increase the concentration of LiF, i.e., an F-source, and second to induce the formation of Li x PF y and phosphiate/phosphites. Recollecting the reduced swelling of the anode by synergy effect of IF-CE+FEC, the IF-CE derived inorganics-rich species, which enables an improvement of mechanical strength making the SEI layer robust, is ascribed to the suppression of swelling event on SiO-graphite anode.…”

State‐of‐the‐art lithium (Li)‐ion batteries employ silicon anode active material at a limited fraction while strongly relying on fluoroethylene carbonate (FEC) electrolyte additive exceeding 10 wt.% to enable stable cycling. The swelling issue of silicon in the aspect of solid electrolyte interphase (SEI) instability and a risk of safety hazards and high manufacturing cost due to FEC has motivated the authors to design a well‐working fluorinated additive substitute. High‐capacity cells employing nickel‐rich oxide cathode are pursued by operating at > 4.2 V versus Li/Li+, for which anodic stability of electrolyte is required. Herein, a highly effective new ambifunctional additive of icosafluoro‐15‐crown 5‐ether is proposed at a little fraction of 0.4 wt.% for the stabilized interfaces and reduced swelling of high capacity (3.5 mAh cm−2) 5 wt.% SiO‐graphite anode and LiNi0.88Co0.08Mn0.04O2 cathode. Utilizing together with a lowered fraction of FEC, reversible long 300 cycles at 4.35 V and 1 C (225 mA g−1) are achieved. Material characterization results reveal that such stabilization is derived from the surface passivation of both anode and cathode with perfluoro ether, LiF, and LixPFy species. The present study gives insight into electrolyte formulation design with lower cost and both‐side stabilization strategies for silicon and nickel‐rich active materials and their interfaces.

“…[ 33,35 ] The Li 1 s spectrum exhibits two peaks at 54.7 and 55.5 eV, corresponding to Li 2 CO 3 and LiF (Figure S4c, Supporting Information). [ 33,34,38 ] In the F 1 s spectrum (Figure S4d, Supporting Information), the peak at 684.6 eV supports LiF. The peak at 687.0 eV is ascribed to PFO‐containing compounds, possibly organophosphorus fluoride.…”

As an anode material of lithium‐ion batteries (LIB), Sn has great application potential due to its high theoretical specific capacity. However, the Li–Sn alloying reaction causes serious volume expansion and destroys the electrode structure, resulting in a rapid capacity decay. Herein, a simple preparation method for the Sn–carbon composites (Sn/CF) is designed by electrodepositing Sn nanoparticles on 3D carbon foam (CF) derived from the carbonization of melamine. Sn/CF‐3h exhibits excellent electrochemical properties. At 1 A g−1, the specific capacity of Sn/CF‐3h remains 166.6 mAh g−1 with a high capacity retention of 85.4% even over 2000 cycles. The designed structure of the Sn/CF electrode contributes to its excellent performance: providing a 3D conductive network, accommodating volume changes to prevent Sn nanoparticles from losing electrical contact, and promoting contact with electrolyte to accelerate lithium ion transmission.

“…Recently, owing to the demand for energy storage systems, including electric car batteries, the requirement for the production of secondary batteries, particularly, Li-ion batteries (LiB) is significantly high [ 1 , 2 , 3 , 4 , 5 , 6 ]. In addition to the advancements in the search for alternatives for energy storage systems, research has been devoted to developing high-performance LiBs with better safety and lifetime [ 7 , 8 , 9 , 10 , 11 , 12 ]. Simultaneously, there has been considerable attention on environmental issues potentially arising from the waste or manufacturing procedures of LiB [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ].…”

Solvent-Free Processed Cathode Slurry with Carbon Nanotube Conductors for Li-Ion Batteries

The increase in demand for energy storage devices, including portable electronic devices, electronic mobile devices, and energy storage systems, has led to substantial growth in the market for Li-ion batteries (LiB). However, the resulting environmental concerns from the waste of LiB and pollutants from the manufacturing process have attracted considerable attention. In particular, N-methylpyrrolidone, which is utilized during the manufacturing process for preparing cathode or anode slurries, is a toxic organic pollutant. Therefore, the dry-based process for electrodes is of special interest nowadays. Herein, we report the fabrication of a cathode by a mortar-based dry process using NCM811, a carbon conductor, and poly(tetrafluoroethylene)binder. The electrochemical performance of the cathode was compared in terms of the types of conductors: carbon nanotubes and carbon black. The electrodes with carbon nanotubes showed an ameliorated performance in terms of cycle testing, capacity retention, and mechanical properties.
