Special Issue Information

Dear Colleagues,

Lithium-ion (Li-ion) based battery technologies represent an omnipresent aspect of energy storage in modern life. Increasing demands for capacity, high power density, increased safety and cycling life for use in automotive applications and various portable devices drive ongoing needs for advances in the design of novel battery materials and systems. Multiple avenues are of interest for improving overall performance and safety of these systems, including investigation of high-voltage cathodes, high-capacity anodes, electrolytes with improved transport and electrochemical stability, design of solid electrolyte interphases (SEI) with desired mechanical and transport characteristics, minimization of self-discharge and electrode degradation, etc. These effects, in turn, may be accomplished either via development of entirely new or modified materials, or through development of new formulations which utilize existing compounds in novel ways to enable better electrochemical performance.

This Special Issue invites manuscripts that discuss experiemental or modeling investigations of new chemical or physical formulations for cathodes, anodes, electrolytes, or solid electrolyte interphases in Li-ion based batteries. These investigations may involve new chemical compounds that show promise as major phases for Li-ion based systems (e.g., high-voltage spinels, LiPON electrolytes, “water-in-salt” electrolytes, etc.), or new methods of processing current compounds to achieve novel structures (e.g., composite graphite/Si anodes, nanostructured composite cathodes), which increase the overall capability of these compounds above their currently utilized configurations.

A potential list of topics may include, but are not limited to, the following areas of exploration:

  • Solid electrolytes (polymer electrolytes, gel electrolytes, solid state ion conductors, etc.)
  • New or novel electrode materials or modifications of currently utilized electrode materials
  • Utilization of existing electrode materials in composite and/or nanostructured compound electrode construction
  • Electrolyte formulations and additive compounds designed to increase performance of electrode passivation layers and SEIs.

The chlorine (Cl) and bromine (Br) co-doped lithium nickel manganese cobalt oxide (LiNi1/3Co1/3Mn1/3O2) was successfully synthesized by the molten salt method. The synthesized LiNi1/3Co1/3Mn1/3O2 compound demonstrates spherical morphology, which is formed by aggregated spherical-like or polygon primary particles. Halogen substitution would contribute to the growth of the primary particles. The LiNi1/3Co1/3Mn1/3O2 compound has the typical hexagonal layered structure, and no impurity phase is detected. The surface oxidation state of the compound is improved after Cl and Br substitution. Moreover, the Cl and Br co-doped LiNi1/3Co1/3Mn1/3O2 compound exhibits both improved rate capacity and cycle stability at a high voltage (4.6 V) compared with the pristine LiNi1/3Co1/3Mn1/3O2. The initial discharge capacities of Cl and Br co-doped LiNi1/3Co1/3Mn1/3O2 are 208.9 mAh g−1, 200.6 mAh g−1, 188.2 mAh g−1, 173.3 mAh g−1, and 157.1 mAh g−1 at the corresponding rates of 0.1C, 0.2C, 0.5C, 1C, and 3C respectively. The capacity retention at 1C after 50 cycles is increased from 81.1% to 93.2% by co-doping. The better contact between the electroactive particles of the electrode and the smaller resistance enhance the electric conductivity of the Cl and Br co-doped LiNi1/3Co1/3Mn1/3O2 cathode. The synthesized LiNi1/3Co1/3Mn1/3O2 is a promising cathode material for a high-power and large-capacity lithium-ion battery. Full article
