We fabricate diverse geometric scales of lithium-ion battery (LIB) pattern assemblies in CR2032-circular coin designs by using complex building-block (CBB) anode/cathode electrodes as hierarchical models. The CBB anode/cathode electrode architectonics are designed with multiple complex hierarchies, including uni-, bi-, and tri-modal morphologies, multi-directional configurations, geometrical assemblies oriented in nano-/micro-scale structures, and surface mesh topologies, which allow us to leverage half-and full-cell CBB-LIB models. The CBB-LIB CR2032-circular coin designs have a Coulombic efficacy of ~99.7% even after 2000 th lithiation/delithiation (discharge/charge) cycles, an outstanding battery energy density of 154.4Wh/kg, and a specific discharge capacity of 163.6 mAh/g from 0.8 V to 3.5 V and at 0.1 C. The architectonic configurations and geometrics of the modulated full-cell CBB-LIB CR2032-circular designs play key roles in creating sustainable, full-scale CBB-mutated-LIBs with continuous and non-resisted surface transports and in achieving a sensible distribution of electron/Li + ions. With hierarchical uni-, bi-, and tri-modal complexities, a dense collar packing f anode/cathode CBBmutated-LIB pouch-type sets in stacked layers can facilitate a rational design of CBB-pouch-type LIBs. Our CBB-mutated pouch-type LIB models have a sustainable Li + ion-transport along multicomplex CBB-surfaces, substantial areal discharging capacity, and excellent volumetric-and gravimetric-cell energy densities and specific capacitances that fulfill the powerful force-driving range and tradeoff requirements in electric vehicle applications.

There are plenty of issues need to be solved before the practical application of Li- and Mn-rich cathodes, including the detrimental voltage decay and mediocre rate capability, etc. Element doping can effectively solve the above problems, but cause the loss of capacity. The introduction of appropriate defects can compensate the capacity loss; however, it will lead to structural mismatch and stress accumulation. Herein, a three-in-one method that combines cation–polyanion co-doping, defect construction, and stress engineering is proposed. The co-doped Na+/SO42− can stabilize the layer framework and enhance the capacity and voltage stability. The induced defects would activate more reaction sites and promote the electrochemical performance. Meanwhile, the unique alternately distributed defect bands and crystal bands structure can alleviate the stress accumulation caused by changes of cell parameters upon cycling. Consequently, the modified sample retains a capacity of 273 mAh g−1 with a high-capacity retention of 94.1% after 100 cycles at 0.2 C, and 152 mAh g−1 after 1000 cycles at 2 C, the corresponding voltage attenuation is less than 0.907 mV per cycle.

“…Various approaches have been proposed to overcome the shortcomings of LIB design procedures in terms of actual system performance in theory and practical implementation in potential applications. For instance, optimal LIB-mutated anode/cathode electrode designs were reported by using multi-component composites, electronic and conductive cuticles, and hierarchically-shaped structures that can offer multi-diffusive open sites for promising storage modules [8][9][10][11][12][13][14].…”

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 superarchitectonics 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 multiaxial/dimension GPS cathode-and anode-electrode geometrics and multi-gate-intransports of electron/Li+ ions in diverse pathways. Our precisely defined GPSmodulated 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 cycles, "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.
