Abstract

With the aim of improving the rate capability and the safety of nanocrystalline Li4Ti5O12-based high power lithium ion batteries, two high boiling point nitrile-based electrolytes namely, 3-ethoxypropionitrile (CH3CH2OCH2CH2CN, EPN)/1 M LiTFSI and 3-(2,2,2-trifluoro)ethoxypropionitrile (CF3CH2OCH2CH2CN, FEPN)/1 M LiTFSI, are investigated in this study. Both electrolytes demonstrated superior rate capability to that of EC + DMC-based electrolyte, owing to the fast interfacial charge transfer process of lithium insertion/extraction.

Lithium-ion battery

A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. The negative electrode of a conventional lithium-ion cell is typically graphite, a form of carbon. This negative electrode is sometimes called the anode as it acts as an anode during discharge. The positive electrode is typically a metal oxide; the positive electrode is sometimes called the cathode as it acts as a cathode during discharge.

Lithium iron phosphate

Lithium iron phosphate or lithium ferro-phosphate (LFP) is an inorganic compound with the formula LiFePO4. It is a gray, red-grey, brown or black solid that is insoluble in water. The material has attracted attention as a component of lithium iron phosphate batteries, a type of Li-ion battery. This battery chemistry is targeted for use in power tools, electric vehicles, solar energy installations and more recently large grid-scale energy storage.

Pseudocapacitance

Pseudocapacitance is the electrochemical storage of electricity in an electrochemical capacitor known as a pseudocapacitor. This faradaic charge transfer originates by a very fast sequence of reversible faradaic redox, electrosorption or intercalation processes on the surface of suitable electrodes. Pseudocapacitance is accompanied by an electron charge-transfer between electrolyte and electrode coming from a de-solvated and adsorbed ion. One electron per charge unit is involved.
