摘      要：The ether electrolytes usually outperform ester electrolytes by evaluating sodium-ion batteries(SIBs)rate performance,which is a near-unanimous conclusion of previous studies based on an essential configuration of the half-cell ***,here we find that contrary to consensus,the ester electrolyte shows better Na storage capability than the ether electrolyte in full *** in-depth analysis of three-electrode,symmetric cell,and in situ XRD tests indicates that traditional half-cell test results are unreliable due to interference from Na *** particular,Na electrodes show a huge stability difference in ester and ether electrolytes,and ester electrolytes suffer more severe interference than ether electrolytes,resulting in the belief that esters are far inferior to ether *** seriously,the more accurate three-electrode test would also suffer from Na electrode ***,a“corrected half-cell testprotocol is developed to shield the Na electrode interference,revealing the very close super rate capability of hard carbon in ester and ether *** work breaks the inherent perception that the kinetic properties of ester electrolytes are inferior to ethers in sodium-ion batteries,reveals the pitfalls of half-cell tests,and proposes a new test protocol for reliable results,greatly accelerating the commercialization of sodium-ion batteries.
