“…Encouraged by the above‐mentioned methods and combination of other novel strategies, such as optimization of experimental conditions (such as calcinations temperature and time, selection of precursors and carbon sources, and optimization of Fe/Mn ratio), special morphology design, cation/anion doping, and surface coating/compositing by other conductive agents or lithium ion conductor, investigation on the improvement of the electrochemical performances and thermal stability of LFMP‐based cathode materials has always been a hot spot in the very recent years. A number of Mn‐rich LiFe 1‐ y Mn y PO 4 /C (0.5 ≤ y < 1.0) cathode materials with high specific capacity, superior rate performance, and excellent cycle stability have also been reported …”

“…However, massive carbon (≈10 wt%) in most LiFe 1‐ y Mn y PO 4 /C ( y ≥ 0.5) cathode materials with high rate performance will lead to a relatively low energy density, especially for volume energy density.

LiMnPO 4 (LMP) is one of the most potential candidates for high energy density (≈700 W h kg -1 ) lithium ion batteries (LIBs). However, the intrinsically low electronic conductivity and lithium ion diffusion coefficient of LMP result in its low performance. To overcome these challenges, it is an effective approach to prepare nanometer-sized Fe-doping LMP (LFMP) materials through optimization of the preparation routes. Moreover, surface coating can improve the ionic and electronic conductivity, and decrease the interfacial side reactions between the nanometer particles and electrolyte. Thus, a uniform surface coating will lead to a significant enhancement of the electrochemical performance of LFMP. Currently, considerable efforts have been devoted to improving the electrochemical performance of LiFe 1-y Mn y PO 4 (0.5 ≤ y < 1.0) and some important progresses have been achieved. Here, a general overview of the structural features, typical electrochemical behavior, delithiation/ lithiation mechanisms, and thermodynamic properties of LiFe 1-y Mn y PO 4based materials is presented. The recent developments achieved in improvement of the electrochemical performances of LiFe 1-y Mn y PO 4 -based materials are summarized, including selecting the synthetic methods, nanostructuring, surface coating, optimizing Fe/Mn ratios and particle morphologies, cation/ anion doping, and rational designing of LFMP-based full cells. Finally, the critical issues at present and future development of LiFe 1-y Mn y PO 4 -based materials are discussed.of LIBs. [3,4] Investigation on the design and preparation of high performance cathode materials has received extensive attention from academic and industrial research worldwide. The first successful example of LiCoO 2 discovered by Goodenough and his co-workers in 1980 is a dominating cathode material in commercial portable electronic devices. [5] It displays medium specific capacity and high compaction density when it is employed as a cathode material in the fabrication of electrode, resulting in its high energy density. In order to improve the safety of LIBs, decrease the cost and to enhance specific capacity, researchers have been trying to find other efficient materials. Many oxide-based positive insertion materials, such as LiMn 2 O 4 , [6] LiMn 1.5 Ni 0.5 O 4 , [7] LiNi 0.8 Co 0.15 Al 0.05 O 2 [8]and LiMn 0.33 Co 0.33 Ni 0.33 O 2[9] were proposed as possible alternatives to the existing layered LiCoO 2 cathodes because of its own shortcomings, such as the toxicity and high cost of cobalt as well as its poor thermal stability. [10] Figure 1 illustrates crystal structures and discharge curves for some typical cathode materials, including layered LiCoO , spinel LiNi 0.5 Mn 1.5 O 4 and olivine LiFePO 4 , in which spinel and olivine materials show flat potential plateaus, while layered materials display sloping potential profiles. [11] Besides the transition metal oxides-based cathode materials, phospho-olivines introduced firstly by Goodenough and co-workers in 1997 as cathode materials for L...

The electrodes of lithium-ion batteries (LIBs) are multicomponent systems and their electrochemical properties are influenced by each component, therefore the composition of electrodes should be properly balanced. At the beginning of lithium-ion battery research, most attention was paid to the nature, size, and morphology peculiarities of inorganic active components as the main components which determine the functional properties of electrode materials. Over the past decade, considerable attention has been paid to development of new binders, as the binders have shown great effect on the electrochemical performance of electrodes in LIBs. The study of new conductive binders, in particular water-based binders with enhanced electronic and ionic conductivity, has become a trend in the development of new electrode materials, especially the conversion/alloying-type anodes. This mini-review provides a summary on the progress of current research of the effects of binders on the electrochemical properties of intercalation electrodes, with particular attention to the mechanisms of binder effects. The comparative analysis of effects of three different binders (PEDOT:PSS/CMC, CMC, and PVDF) for a number of oxide-based and phosphate-based positive and negative electrodes for lithium-ion batteries was performed based on literature and our own published research data. It reveals that the combined PEDOT:PSS/CMC binder can be considered as a versatile component of lithium-ion battery electrode materials (for both positive and negative electrodes), effective in the wide range of electrode potentials.

“…К числу таких недостатков относятся относительно низкая проводимость литиймарганцевой шпинели и быстрое падение разрядной ёмкости при циклировании заряд-разряда [6]. Одним из основных факторов, определяющих такое поведение материала, является структурная нестабильность шпинели, её электрохимическое растворение при перезарядке части ионов марганца до состояния марганца (III) и последующего диспропорционирования, ведущего к ослаблению связи иона марганца в решётке и его частичному выходу в раствор © ВОРОБЬЕВА К.

Поступила в редакцию 03.03.16 г. Методом циклической вольтамперометрии в водном и пропиленкарбонатном растворах перхлората лития проведено исследование электрохимических свойств электродов на основе литий-марганцевой шпинели (LiMn 2 O 4), для изготовления которых в качестве электронопроводящей добавки и связующего использовали проводящий полимер поли-3,4этилендиокситиофен/полистиролсульфонат (PEDOT:PSS) и карбоксиметилцеллюлоза (CMC). Получены величины удельной ёмкости катодного материала и их зависимости от скорости развёртки потенциала. Проведено сравнение полученных функциональных характеристик материалов стандартного состава с использованием традиционного связующего поливинилиденфторида (PVDF) и состава с использованием проводящей полимерной дисперсии. Показано, что введение в состав катодного материала проводящего полимера приводит к увеличению удельной ёмкости (до 10%) и улучшению стабильности материала при циклировании потенциала. Ключевые слова: литий-марганцевая шпинель, PEDOT:PSS, циклическая вольтамперометрия, литий-ионные аккумуляторы.
