Abstract

Given exceptional specific discharge capacity, excellent energy density, high rate capability, fast charge capacity, and long-term cycling stability, large-scale giant porous complex super-architectonics (GPS) integrated into anode/cathode complex geometrics improve the full-model lithium ion batteries (LIBs). We examine the integration of a series of anode and cathode (GPS) super-architectonics into half- and full-cell LIB models to allow non-prescriptive charge/discharge cycles, and to achieve spatial rate performance capabilities. As a distinguishable GPS model, the super-architectonics included multi-directional orientation geometrics, building-blocks egress/ingress pathways, and giant loophole-on-surface topographies of ripples, irregular bumps, undulations, and anticlines offer a set of fully functional multi-axial/dimension GPS cathode- and anode-electrode geometrics and multi-gate-in-transports of electron/Li+ ions in diverse pathways. Our precisely defined GPS-modulated LIB models generate high-power and volumetric-energy density, excellent long-term cycling durability without deterioration in its capacity under a high energy density, and a comparable high tap density. GPS-integrated LIB modules provide superior durability (i.e., maintaining high specific capacity ∼77.5% within long-term life period of 2000 cycles) and average Coulombic efficacy of ∼99.6% at 1 C. Powerful and robust super-architectonic GPS building-blocks-in full-scale LIB designs offer outstanding specific energy density of ≈179 Wh kg–1 for a future market of LIB-EVs with longest driving range. The key leap super-surface topographies of LIB-GPS modules are critical in creating ever-changing charge/discharge cycle, “fully cycled dynamics,” affordable on-/off-site storage, and super-large door-in transport of Li+-ion/electron, thereby highlighting its promising storage modules and rechargeable lithium batteries.
