Abstract: Reduction in the tortuosity of electrodes is a favored strategy to enhance the fast-charging capability of lithium-ion batteries by optimizing the ion-transfer kinetics. A facile, low-cost, highly controllable, and high-output continual additive manufacturing roll-to-roll screen printing technology is disclosed herein to render customized vertical channels within electrodes. High-accuracy vertical channels were fabricated by applying as-developed inks, using LiNi0.6Mn0.2Co0.2O2, for example, as the cathode material. The optimized screen-printed electrode exhibited a seven-fold higher specific charge capacity (72 mAh/g) at a current rate of 6 C and superior stability compared with that of the conventional bar-coated electrode (10 mAh/g, 6 C) at a mass loading of 10 mg/cm2.

Abstract: Current sulfide solid-state electrolyte (SE) membranes utilized in all-solid-state lithium batteries (ASLBs) have a high thickness (0.5˜1.0 mm) and low ion conductance (<25 mS), which limit the cell-level energy and power densities. Based on ethyl cellulose's unique amphipathic molecular structure, superior thermal stability, and excellent binding capability, this work fabricated a freestanding SE membrane with an ultralow thickness of 47 ?m. With ethyl cellulose as an effective disperser and binder, the Li6PS5Cl is uniformly dispersed in toluene and possesses superior film formability. In addition, ultralow areal resistance of 5.10 ?cm?2 and remarkable ion conductance of 190.11 mS (one order higher than the conventional sulfide SE layer) have been achieved. The ASLB assembled with this SE membrane delivers cell-level high gravimetric and volumetric energy densities of 175 Wh kg?1 and 675 Wh L?1, individually.

Abstract: Solar cell substrates require high optical transparency, but also prefer high optical haze to increase the light scattering and consequently the absorption in the active materials. Unfortunately, there is a tradeoff between these optical properties, which is exemplified by common transparent paper substrates exhibiting a transparency of about 90% yet a low optical haze (<20%). In this work we introduce a novel transparent paper made of wood fibers that display both ultra-high optical transparency (˜96%) and ultra-high haze (˜60%), thus delivering an optimal substrate design for solar cell devices. Compared to previously demonstrated nanopaper composed of wood-based cellulose nanofibers, our novel transparent paper has better dual performance in transmittance and haze, but also is fabricated at a much lower cost. This high-performance, low-cost transparent paper is a potentially revolutionary material that may influence a new generation of environmentally friendly printed electronics.
