“…The double-layer capacitance is known to be directly proportional to the surface area. 39 But for this system, the capacitance difference of C 60 CoTMPP_900s is much larger than that of their BET surface areas. This implies that the doping state of Co–N should bring great influence on their effective surface area for ion diffusion and conversion, which leads to a large difference in the electrochemical performance.…”

Lithium-ion batteries with ultra-thick electrodes have high energy density and low manufacturing costs because of the reduction of the inactive materials in the same battery volume. However, the partial usage of the full capacity and the low rate capability are caused by poor ionic and electronic conduction. In this work, the effects of two approaches, such as electrode binder carbonization by heat treatment and 3-dimensionalization by the laser structuring of ultra-thick graphite anodes to lithium-ion batteries for high energy density, are investigated. During the heat treatment, the polyvinylidene fluoride (PVDF) binder is carbonized to form fluorinated graphitic carbons, thereby increasing the number of lithium-ion storage sites and the improvement of the electrode capacity by 14% (420 mAh g−1 and 20 mAh cm−2). Further, the carbonization improves the rate capability by 31% at 0.1 C by simultaneously reducing the ionic and electronic resistances. Furthermore, after the laser structuring of the carbonized electrode, the areal discharge capacity increases to 50% at the increasing current rates, resulting from drastically improved ionic conduction. In addition to the electrochemical characteristics, these two approaches contribute considerably to the fast wetting of the electrolyte into the ultra-thick electrode. The carbonization and laser structuring of the ultra-thick graphite anodes are practical approaches for high-energy batteries to overcome the thickness limitation.

“…The large specific surface area of wet stabilized CNF‐based aerogels is beneficial in applications, such as energy storage, particularly in supercapacitors where greater surface area to volume ratios improve performance. [ 63 ] The intimate molecular contact achieved with the LbL‐technique is also beneficial for efficient charge transfer. [ 64 ] Hamedi et al.…”

The Use of Layer‐by‐Layer Self‐Assembly and Nanocellulose to Prepare Advanced Functional Materials

The current knowledge about the formation of layer‐by‐layer (LbL) self‐assemblies using combinations of nanocelluloses (NCs) and polyelectrolytes is reviewed. Herein, the fundamentals behind the LbL formation, with a major focus on NCs, are considered. Following this, a special description of the limiting factors for the formation of LbLs of only NCs, both anionic and cationic, and the combination of NCs and polyelectrolytes/nanoparticles is provided. The ability of the NCs and polyelectrolytes to form dense films with excellent mechanical properties and with tailored optical properties is then reviewed. How low‐density, wet stable networks of cellulose nanofibrils can be used as substrates for the preparation of antibacterial, electrically interactive, and fire‐retardant materials by forming well‐defined LbLs inside these networks is then considered. A short outlook of the possible uses of LbLs containing NCs is given to conclude.
