Title: Electrochemical Lithium Ion Battery Performance Model

Abstract

The Electrochemical Lithium Ion Battery Performance Model allows for the computer prediction of the basic thermal, electrical, and electrochemical performance of a lithium ion cell with simplified geometry. The model solves governing equations describing the movement of lithium ions within and between the negative and positive electrodes. The governing equations were first formulated by Fuller, Doyle, and Newman and published in J. Electrochemical Society in 1994. The present model solves the partial differential equations governing charge transfer kinetics and charge, species, heat transports in a computationally-efficient manner using the finite volume method, with special consideration given for solving the model under conditions of applied current, voltage, power, and load resistance.

  • Li-rich Li{sub 1.2}Ni{sub 0.17}Co{sub 0.17}Mn{sub 0.5}O{sub 2} cathode materials were synthesized by electrospinning technique with different polymers, and their structural, morphological, and electrochemical performances were investigated. It was found that the electrospinning process leads to the formation of a fiber and flower-like morphology, by using different polymers and heat treatment conditions. The nanostructured morphology provided these materials with high initial discharge capacity. The cycling stability was improved with agglomerated nano-particles, as compared with porous materials. - Highlights: • Fiber and flower-like Li-rich cathode was synthesized by simple electrospinning. • Polymer dependent morphology and electrochemical performance was investigated. • Well-organized porousmore » structure facilitates the diffusion of lithium ions. • Technique could be applicable to other cathode materials as well.« less

Tetrabutyl titanate and graphene were dispersed in tertbutanol and heated to reflux state by microwave irradiation. Followed by adding lithium acetate to produce LTO precursor/graphene (p-LTO/G). The resulting p-LTO/G offers homogeneous morphology and ultra small size. All graphene sheets were buried in the spherical agglomerates composed of primitive particles through the second agglomeration. The p-LTO/G was calcined to LTO@graphene (LTO@G). To obtain G@LTO@G, the LTO@G was further hybridized with graphene. The as-prepared G@LTO@G shows well-defined three-dimensional structure and hierarchical porous distribution. Its unique architecture creates big tap density, fast electron transfer and rapid electrolyte transport. As a result, the G@LTO@G provides high specific capacity (175.2 mA h g{sup −1} and 293.5 mA cm{sup −3}), outstanding rate capability (155.7 mAh g{sup −1} at 10C) and intriguing cycling stability (97.2% capacity retention at 5C after 1000 cycles)« less
  • Carbon-coated natural graphite has been prepared by thermal vapor decomposition treatment of natural graphite at 1,000 C. Natural graphite coated with carbon showed much better electrochemical performance as an anode material in both propylene carbonate-based and ethylene carbonate-based electrolytes than bare natural graphite. The effect of carbon coating on the electrochemical performance was investigated by solid-state {sup 7}Li-NMR in conjunction with standard electrochemical techniques.

With the increase of Co content the lattice parameters decrease owing to the smallermore » ion radius of Co than Mn. The reversible capacity and cyclability of Ni(Mn{sub 2−x}Co{sub x})O{sub 4} first increase and then decrease with the increase of Co content and NiMn{sub 1.5}Co{sub 0.5}O{sub 4} shows the best electrochemical performance in compared to the other two samples. Neutron diffraction and Rielveld refinement are further applied to analyze the site occupancies of the elements of Mn, Co, O and Ni. A certain amount of Co ions substitution are favorable to enhance the electrochemical performance, but excessive Co ions in 8a and 16d sites reduce the stability of host structure which leads to the poor electrochemical performance.« less
