“…105,106 Yazami et al 105,107 explained the complicated arc shape by surface-film formation followed by electrode gassing during the decomposition of the electrolyte. A depressed highfrequency arc may be due to the overlapping of two, or even more arcs and may be associated with grain-boundary resistance in the SEI.…”

The Solid-Electrolyte-Interphase (SEI) model for non-aqueous alkali-metal batteries constitutes a paradigm change in the understanding of lithium batteries and has thus enabled the development of safer, durable, higher-power and lower-cost lithium batteries for portable and EV applications. Prior to the publication of the SEI model (1979), researchers used the Butler-Volmer equation, in which a direct electron transfer from the electrode to lithium cations in the solution is assumed. The SEI model proved that this is a mistaken concept and that, in practice, the transfer of electrons from the electrode to the solution in a lithium battery, must be prevented, since it will result in fast self-discharge of the active materials and poor battery performance. This model provides [E. Peled, in "Lithium Batteries," J.P. Gabano (ed), Academic Press, (1983), E. Peled, J. Electrochem. Soc., 126, 2047Soc., 126, (1979.] new equations for: electrode kinetics (i o and b), anode corrosion, SEI resistivity and growth rate and irreversible capacity loss of lithium-ion batteries. This model became a cornerstone in the science and technology of lithium batteries. This paper reviews the past, present and the future of SEI batteries. The PastPrior to the publication of the SEI model (1979), 1,4 researchers used the Butler-Volmer equation, in which direct electron transfer from the electrode to lithium cations in the solution is assumed. It was generally assumed that the rate-determining step (RDS) is the transfer of electrons from the metal to the cations in the solution. Researchers found that the lithium anode is covered by a passivating layer which interferes with the deposition/dissolution process of the anode. Brummer and Newman 2,3 concluded that a passivating anode can offer only a limited cycle life and in order to obtain a deep-discharge high-cycle-life secondary battery, the lithium anode must be free of a passivating layer and kinetically stable with respect to the electrolyte. The SEI model proved that this is a mistaken concept and that, in practice, the transfer of electrons from the electrode to the solution in a lithium battery, except when forming a SEI, must be prevented. The Present, Lithium-Metal and Lithium-Ion BatteriesIntroduction.-It is now generally accepted that the solidelectrolyte interphase (SEI) is essentially for the existence and successful operation of lithium-and sodium-battery systems, as primary and secondary power sources. 4 In 1979, it was proposed by Peled,

“…However, in the cases of LiClO 4 or LiBF 4 / EC-PC-DME (dimethoxy-ethane), only one high-frequency distorted semicircle was found in the impedance spectra. 106 Yazami et al 106,108 explained the complicated arc shape by surface-film formation followed by electrode gassing during the decomposition of the electrolyte. This phenomenon is less pronounced in Li-triflate, Li-imide and lithium hexafluorophosphate.…”

Effects of styrene-butadiene rubber/carboxymethylcellulose (SBR/CMC) and polyvinylidene difluoride (PVDF) binders on the electrochemical characteristics of a type of microsize MCMB (mesocarbon microbeads) anode (SMA) at low temperature are investigated by cold/heat shock testing, differential scanning calorimetry, scanning electron microscopy, electrochemical impedance spectroscopy, coin cell testing and 18650 full cell testing. Under low temperature conditions and compared to the SMA electrode with a SBR/CMC binder, the SMA electrode with a PVDF binder has lower impedance, lower charge transfer resistance, better rate capability and superior cycleability.Lithium ion batteries (LIBs) are at present dominating as power supplies in small sized general portable consumer electronics applications in the information technology (IT) industry. During recent decades, LIBs have undergone revolutionary technological progress in design and application. Development of LIBs for low temperature use has become an issue of great concern, especially for high power applications such as in aerospace, military and hybrid electric vehicles. 1-3 Lithium insertion and extraction in anode materials involve solid/electrolyte interface (SEI) formation, 4,5 although the twophase reaction theory has been challenged at low temperatures. In any case, it is widely observed that the insertion and extraction of lithium is more difficult at low temperatures. Great efforts have been made to enhance the lithium ion transport properties of SEI films on carbon anodes by approaching cell design from the related low temperature conditions. 6-8 Most previous researchers 9-13 have attempted to improve LIB low temperature performance by developing electrolytes with increased ionic conductivities. Among such studies, application of micro-sized materials and their shorter ionic diffusion paths to electrodes is considered one of the attractive solutions to the problem. However, recent work 14,15 has demonstrated that the primary cause of poor Li-ion cell performance at low temperatures is not related to organic electrolytes or SEI films but is in fact related to Li ion diffusion in negative electrodes with a polyvinylidene difluoride (PVDF) binder. The resistance to ionic flow at low temperatures is therefore a major factor in the performance of carbon-based negative electrodes in LIBs.Most polymers at room temperature show the familiar polymeric properties of material flexibility and high resistance to cracking. Typically, the long molecular chains of most polymers at moderate temperatures are able to stretch, deform and slither over one another. Accordingly, at normal temperatures, polymer materials are flexible, do not crack and are considered to be in a 'rubbery' state. But when the temperature drops through the 'glass transition region,' i.e. falls below the glass transition temperature (Tg), most polymers stiffen up and become glassy solids that are very hard and brittle. For the −40 • C to 80 • C operating temperature range of Li-ion batteries, low tem...
