Abstract
Abstract Magnesium‐ion batteries (MIBs) and dual‐salt magnesium/lithium‐ion batteries (MLIBs) have emerged as promising contenders for next‐generation energy storage. In contrast to lithium metal anode in lithium metal batteries, magnesium metal anode in MIBs and MLIBs presents a safer alternative due to the limited dendrite growth and higher volumetric capacity, along with higher natural abundance. This study explores a MLIB configuration with a novel cathode design by employing a 2D/2D nanocomposite of 1T/2H mixed phase MoS 2 and delaminated Ti 3 C 2 T x MXene (1T/2H‐MoS 2 @MXene) to address challenges associated with slow kinetics of magnesium ions during cathode interactions. This cathode design takes advantage of the high electrical conductivity of Ti 3 C 2 T x MXene and the expanded interlayer spacing with enhanced conductivity of the 1T metallic phase in 1T/2H mixed phase MoS 2 . Through a designed synthesis method, the resulting nanocomposite cathode maintains structural integrity, enabling the stable and reversible storage of dual Mg 2+ and Li + ions. The nanocomposite cathode demonstrates superior performance in MLIBs compared to individual components (253 mAh g −1 at 50 mA g −1 , and 36% of capacity retention at 1,000 mA g −1 ), showcasing short ion transport paths and fast ion storage kinetics. This work represents a significant advancement in cathode material design for cost‐effective and safe MLIBs.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
