In this paper, molybdenum-doped LiMn0.6Fe0.4PO4 cathode materials were prepared by spray drying combined with carbon thermal reduction. XRD and SEM test results showed ...
Moreover, the recent achievements in nanostructured positive electrode materials for some of the latest emerging rechargeable batteries are also summarized, such as Zn-ion batteries, F- and Cl-ion ...
For the negative electrode, the first commercially successful option that replaced lithium–carbon-based materials is also difficult to change. Several factors contribute to this continuity: (i) a low cost of many carbon-based materials, (ii) well established intercalation chemistry and other forms of reactivity towards lithium, and (iii) …
Thus, with silicon carbon as the negative electrode materials, such oxide materials as lithium-rich layered oxides, nickel-rich layered oxides, and high-voltage spinel LiMn 1.5 Ni 0.5 O 4 can be used as the potential PEMs for …

Intensive research has revealed the complex components of CEI in high-energy-density positive electrodes, such as Li 2 CO 3 (mainly from an initial contaminant), …
Phospho‐olivines as Positive‐Electrode Materials for Rechargeable Lithium Batteries, A. K. Padhi, K. S. Nanjundaswamy, J. B. Goodenough The Electrochemical Society (ECS) was founded in 1902 to advance the theory and practice at the forefront of electrochemical and solid state science and technology, and allied …
Organic electrode materials can be classified as being n-type, p-type or bipolar-type materials according to specific criteria (Box 1), not least their redox chemistry 53.For n-type (p-type ...
Tin oxide (SnO2) and tin-based composites along with carbon have attracted significant interest as negative electrodes for lithium-ion batteries (LIBs). However, tin-based composite electrodes …
6 · SeS2 positive electrodes are promising components for the development of high-energy, non-aqueous lithium sulfur batteries. However, the (electro)chemical and structural evolution of this class of ...
The lithium-ion battery generates a voltage of more than 3.5 V by a combination of a cathode material and carbonaceous anode material, in which the lithium ion reversibly inserts and extracts. Such electrochemical reaction proceeds at a potential of 4 V vs. Li/Li + electrode for cathode and ca. 0 V for anode. Since the energy of a battery depends on …

Highlight 5,7,12,14-Pentacenetetrone (PT) as a positive-electrode active material was examined. The PT-based electrode showed the initial capacity of greater than 200 mAh/g. The PT-based electrode showed a fair cycle performance. A favorable effect of the large π-system on the cycle-life stability was observed.
The key to sustaining the progress in Li-ion batteries lies in the quest for safe, low-cost positive electrode (cathode) materials with desirable energy and power capabilities. One approach to boost the energy and power densities of batteries is to increase the output voltage while maintaining a high capacity, fast charge–discharge rate, …
LiNiO 2 (LNO), NCA and Nickel-rich NMC cathodes are presently those used in the highest energy density lithium-ion cells but can suffer from insufficient cycle life and poor thermal stability. 1–10 Doping LNO with cations like Mg, 11,12 Co, 13 Al, 14,15 Mn, 16 Ti, 17 Zr, 18 Ta, 19 W 20 etc. has been shown to minimize or depress the multiple …
