“…Solutions to these issues have included development of new polymeric binders that can maintain the necessary connectivity between the active material and the electrode surface and bonding the active material directly to the underlying anode current collector. [13][14][15][16][17] A second approach is to use intermetallic insertion electrodes, where the lithium cations are inserted into vacancies within an intermetallic compound to form, in the simplest case, a ternary compound. [18][19][20] Typical materials that have been studied include compounds in the MnSb-LiMnSb and the Cu 2 Sb-Li 2 CuSb systems.…”

Keywords: Electrochemistry / Thin films / Copper / Antimony / Intermetallic phases Although graphitic carbons have been commercially used in lithium-ion batteries for many years, their low crystallographic density limits their use in applications where space is at a premium. Among the alternative anode materials being considered for these applications are Zintl phases and intermetallic insertion anodes. Historically, main-group-metalbased anode materials have had problems with respect to volume expansion experienced on lithiation and its effect on cycle life. In this paper, we report the role of morphology and electrode dimensionality in extending the cycle life of the

“…Another weakness is the difficulty to remove non-reactive monomers from the polymer precursor. In the same spirit, Song et al [36] impregnated a blend of polyethylene glycol diacrylate (PEGDA), PVdF, and poly(methyl methacrylate) (PMMA) into an 85 m poly(ethylene terephthalate) (PET) non-woven by ultraviolet (UV) cross-linking method. In addition to the improvement of the mechanical strength, a good conductivity and liquid electrolyte retention at high temperature was found with respect to untreated gel polymer electrolyte.…”

Electrolytes and Separators for Lithium Batteries

Rechargeable lithium batteries are basically of two types; lithium metal batteries, and, lithium-ion batteries. Lithium metal batteries (LMB) provide a higher theoretical energy density than the alternatives: their wide commercial availability is limited, however, by the tendency to grow dendrites during cycling. This is a potential hazard and also reduces cycle lifetime. Attempts are being made to suppress dendritic growth either by using solid electrolytes that act as mechanical barriers, or by choosing electrolytes that produce a suitable passivation layer called the solid-electrolyte interphase (SEI). Since there is no entirely successful strategy to inhibit the growth of dendrites, safety concerns have led to the use of the other kind of lithium battery, namely, the lithium-ion battery (LiB).Lithium-ion batteries are now widely employed for a variety of applications in electronic devices, mobile telephones, laptop computers and a large variety of other portable appliances. They possess a very high energy density, are light and compact and show excellent cyclability and reliability. The current commercial Li-ion batteries are based on aprotic organic liquids such as ethylene carbonate or dimethyl carbonate which have high dielectric constant and are thus good solvents for salts; they also show a large window of electrochemical stability. However, their vapor pressure is high, so that they can provoke fires and explosions in case of accidental battery shorts, when low-stability cathodes are used such as oxides. Such safety issues become accentuated in large lithium-ion batteries of interest in electric cars, especially if charge-discharge is carried out at high rates. The safety aspect has thus become a paramount issue in the development of this technology. Another component important for safety issue is the separator. This element must have, among other properties, a good wettability with the electrolyte, so that the choice of the separator is dependent on the choice of the electrolyte, one reason why we have chosen to include them in the same chapter.

“…To overcome this problem, the porous separators such as microporous polyolefin membranes and nonwoven mats have been used as the supporting framework to make gel polymer electrolyte for lithium-ion batteries. [17][18][19][20] Here the porous separator serves as the mechanical support, while gel polymer electrolyte coated onto the separator provides the necessary ionic conductivity between electrodes. To our knowledge, no gel polymer electrolytes supported by the porous separator have been reported so far for DSSC applications.…”

Hybrid composite membranes were prepared by coating poly(ethylene oxide) and SiO2 particles onto the porous polypropylene nonwoven matrix. Gel polymer electrolytes prepared by soaking the hybrid composite membranes in an organic electrolyte solution exhibited ionic conductivities higher than 1.1 × 10 -3 S cm -1 at room temperature. Dyesensitized solar cell (DSSC) employing the hybrid composite membrane with PEO and 10 wt % SiO2 exhibited an open circuit voltage of 0.77 V and a short circuit current of 10.78 mA cm -2 at an incident light intensity of 100 mW cm -2 , yielding a conversion efficiency of 5.2%. DSSC employing the hybrid composite membrane showed more stable photovoltaic performance than that of the DSSC assembled with liquid electrolyte.
