Advanced Materials, Год журнала: 2023, Номер 35(32)

Опубликована: Март 24, 2023

Lithium-sulfur (Li-S) batteries have become one of the most promising new-generation energy storage systems owing to their ultrahigh density (2600 Wh kg-1 ), cost-effectiveness, and environmental friendliness. Nevertheless, practical applications are seriously impeded by shuttle effect soluble lithium polysulfides (LiPSs), uncontrolled dendrite growth metallic Li, which result in rapid capacity fading battery safety problems. A systematic comprehensive review cooperative combination tackling fundamental problems terms cathode anode synchronously is still lacking. Herein, for first time, strategies inhibiting behavior dendrite-free Li-S simultaneously summarized classified into three parts, including "two-in-one" S-cathode Li-anode host materials toward full cell, "two birds with stone" modified functional separators, tailoring electrolyte stabilizing sulfur electrodes. This also emphasizes chemistry mechanism catalyst principles improving electrochemical performance; advanced characterization technologies monitor real-time LiPS evolution discussed detail. The problems, perspectives, challenges respect issues as well application proposed.

Next‐Generation Cobalt‐Free Cathodes – A Prospective Solution to the Battery Industry's Cobalt Problem

Advanced Energy Materials, Год журнала: 2022, Номер 12(9)

Опубликована: Янв. 22, 2022

Abstract Lithium‐ion batteries are overreliant on cobalt containing cathodes. Current projections estimate that hundreds of millions electric vehicles (EVs) will be the road by 2050, and this ever‐growing demand threatens to deplete global reserves at an alarming rate. Moreover, supply chain issues have significantly increased prices throughout last decade. As such, energy storage research development need reduce reliance meet for lithium‐ion batteries. The present review summarizes science technology gaps potential numerous cobalt‐free Li‐ion cathodes including layered, spinel, olivine, disordered rock‐salt systems. Despite promising performance these Co‐free cathodes, scale‐up manufacturing bottlenecks associated with materials must also addressed enable widespread adoption in commercial Overall, broadly highlights enormous promise “zero‐cobalt” sustainable production EVs coming decades.

Thermal Stability and Outgassing Behaviors of High‐nickel Cathodes in Lithium‐ion Batteries

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(43)

Опубликована: Июнь 9, 2023

Abstract LiNiO 2 ‐based high‐nickel layered oxide cathodes are regarded as promising cathode materials for high‐energy‐density automotive lithium batteries. Most of the attention thus far has been paid towards addressing their surface and structural instability issues brought by increase Ni content (>90 %) with an aim to enhance cycle stability. However, poor safety performance remains intractable problem commercialization in market, yet it not received appropriate attention. In this review, we focus on gas generation thermal degradation behaviors high‐Ni cathodes, which critical factors determining overall performance. A comprehensive overview mechanisms outgassing runaway reactions is presented analyzed from a chemistry perspective. Finally, discuss challenges insights into developing robust, safe cathodes.

Stable Anode‐Free All‐Solid‐State Lithium Battery through Tuned Metal Wetting on the Copper Current Collector

Advanced Materials, Год журнала: 2022, Номер 35(8)

Опубликована: Ноя. 29, 2022

A stable anode-free all-solid-state battery (AF-ASSB) with sulfide-based solid-electrolyte (SE) (argyrodite Li6 PS5 Cl) is achieved by tuning wetting of lithium metal on "empty" copper current-collector. Lithiophilic 1 µm Li2 Te synthesized exposing the collector to tellurium vapor, followed in situ Li activation during first charge. The significantly reduces electrodeposition/electrodissolution overpotentials and improves Coulombic efficiency (CE). During continuous electrodeposition experiments using half-cells (1 mA cm-2 ), accumulated thickness electrodeposited Te-Cu more than 70 µm, which foil counter-electrode. Full AF-ASSB NMC811 cathode delivers an initial CE 83% at 0.2C, a cycling above 99%. Cryogenic focused ion beam (Cryo-FIB) sectioning demonstrates uniform microstructure, no signs voids or dendrites collector-SE interface. Electrodissolution complete, remaining structurally adherent. By contrast, unmodified Cu current-collector promotes inhomogeneous electrodeposition/electrodissolution, electrochemically inactive "dead metal," that extend into SE, thick non-uniform solid electrolyte interphase (SEI) interspersed pores. Density functional theory (DFT) mesoscale calculations provide complementary insight regarding nucleation-growth behavior. Unlike conventional liquid-electrolyte batteries, role current collector/support lithiophilicity has not been explored for emerging AF-ASSBs.

Advanced Energy Materials, Год журнала: 2023, Номер 13(12)

Опубликована: Фев. 13, 2023

Abstract A rational compositional design is critical for utilizing LiNiO 2 ‐based cathodes with Ni contents > 90% as promising next‐generation cathode materials. Unfortunately, the lack of a fundamental understanding intrinsic roles key elements, such cobalt, manganese, and aluminum, makes high‐Ni limited range dopants (<10%) particularly challenging. Here, 5% single‐element doped cathodes, viz., LiNi 0.95 Co 0.05 O , Mn Al along undoped (LNO), influences are systematically examined through control cutoff charge energy density common practice voltage. Comprehensive investigations into electrochemical properties, combined in‐depth analyses structural interfasial stabilities electrolyte decomposition pathways advanced characterizations, unveil following: i) role regulates or state‐of‐charge and, more critically, occurrence H2–H3 phase transition, which essentially dictates cyclability; ii) LNO can be stabilized well avoidance transition; iii) provides merits overall an optimized operating condition. This work guidance high‐energy‐density sheds light on challenges removing Co.
