Li-water batteries

We discuss below recent progress made in aqueous electrolyte metal/air batteries, non-aqueous electrolyte Li/air batteries and Li/water batteries. These areas have advanced more than the others in recent years. [Pg.85]

The net reaction in a Li-water battery is reaction of LiOH formation with reversible potential of 2.21V and theoretical specific energy of 8530Wh/kgLi [156] ... [Pg.91]

There is increasing interest in preparing Ti02 nanomembranes both for advanced photocatalytic processes in the field of air and water purification, purification of drinking water, novel membrane for high temperature PEM fuel cells,Li-ion batteries,advanced nanoelectrode arrays (NEA) and nanofiltration and pervaporation. ... [Pg.96]

Applications in energy area include Li ion batteries, photovoltaic cells, membrane fuel cells, and dye-sensitized solar cells. Other applications are micropower to operate personal electronic devices via piezoelectric nanofibers woven into clothing, carrier materials for various catalysts, and photocatalytic air/water purification. ... [Pg.11]

In 2002 I have invented a transient, multiscale and multiphysics single fuel cell model, called MEMEPhys. This model, that 1 have continuously developed since then, accounts for the coupling between self-consistent physical-based mechanistic descriptions of the PEM and the CL phenomena (e.g. reactants, water and charge transport and detailed electrochemistry) and different materials aging mechanisms [59, 205-215], The model is designed for simulating hydrogen-feed PEMFC, PEM Water Electrolyzers and Li Ion batteries, but could be easily extended to simulate DAFCs. [Pg.302]

To avoid this accident, for Li-ion batteries, carbon is utilized as the negative active material instead of lithium metal, and Li-containing transition metal oxides are used for the positive active material. The combination of these positive and negative materials gives more than 3 V potential. An organic liquid or polymer electrolyte is used for Li-ion batteries. Water-based electrolytes decompose to oxygen and hydrogen at more than 1.23 V in such batteries. [Pg.356]

A Li-ion battery generally has a voltage range of 3.5-4 V. Aqueous electrolytes cannot be applied to electrolyte solvents, because water decomposes at a voltage... [Pg.360]

The so-called Lewis acids such as LiPEg and LiBF4 are normally used for salts in Li-ion batteries. These salts tend to decompose under water, and to form hydrofluoric acid (HE). The HE is very corrosive to the metal cell-case and to the positive active materials. For this reason, the level of water contamination in electrolyte solution as delivered from electrolyte suppliers is guaranteed to be less than 20 ppm. [Pg.361]
