Published: March 17, 2025

Abstract Designing ionic polymer electrolytes (IPEs) for high‐voltage and fast‐charging lithium batteries involves searching in a highly complex discrete chemical space. Traditional material discovery processes struggle with this complexity due to high costs long evaluation time. A kernel‐based Bayesian optimization is described complete the multi‐objective by considering conductivity, electrochemical stability, discharge capacity simultaneously. According recommender based on union set of acquisition functions, promising IPEs through three iterations only 2.8% space targeted. The achieved metal exhibit performance ultrahigh cutoff voltage NCM811 (LiNi 0.8 Co 0.1 Mn O 2 , 4.8 V) LNMO 0.5 1.5 4 4.92 V). To further extend versatility diminish cost associated glove‐box environment, an aqueous lithium‐ion battery developed introducing water molecules coupled Li Ti 5 12 ||LiMn strong hydrogen bonding network formed between rigid‐rod polyelectrolyte embedded molecules, which effectively suppresses reactivity, meanwhile boosting conductivity.

Abstract All‐solid‐state lithium‐metal batteries (ASSLMBs) with sulfide solid electrolytes have gained significant attention due to their potential for high energy density and enhanced safety. However, development has been hindered by rapid lithium dendrite growth, low coulombic efficiency, poor battery rate performance, cycling stability, posing a major obstacle commercialization. Herein, multifunctional composite electrolyte (M‐CSE) is reported that dynamically stable metal, promoting uniform Li+ deposition without dendrites. The resulting ASSLMBs exhibit an areal capacity of 10 mAh cm − 2 , 219 Wh kg ¹, current 3.76 mA retention 95.04% after 500 cycles at 0.5C. assembled swagelok cell solid‐state pouch cells relatively pressures, the stack pressure ≈30 MPa also ≈2 MPa. More importantly, mass production ultra‐low‐pressure realized 3D printing technology, marking crucial breakthrough practical applications.

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: April 30, 2025

Although a high stack pressure (≥50 MPa) enhances solid-solid contacts in solid-state batteries (SSBs), it poses impracticality for commercialization. This work proposes self-pressure silicon (Si)-carbon composite anode that enables stable operation under reduced external (≤2 MPa). The features prestress structure can effectively alleviate the internal and stress simultaneously, which is fabricated with ionic-conductive poly(ethylene oxide) (PEO)/lithium salt-coated carbon nanotubes (CNTs) being compressed by shrinking graphene hydrogel. capillary-driven hydrogel shrinkage generates pressure, compensating volumetric expansion (up to 300%) of Si. creates dynamic interfaces between CNTs/PEO expanding Si, ensuring both mechanical stability ion/electron transport.
