Kostecki – LBNL V.C.2 Interfacial Processes – Diagnostics (LBNL) Conclusions and Future Directions · LiMnPO 4 composite cathode is unstable vs. LiPF 6 , organic carbonate electrolytes o Electrolyte decomposition products do not form a stable layer on the surface of LiMnPO 4 composite cathode o Surface film forms at the exposed Li x MnPO 4 active material. No surface film was detected on carbon black additive · In situ Raman and fluorescence spectra of LiNi 0.5 Ni 1.5 O 4 single particle cathodes reveal a surface film rich in Li x PO y F z products o Composition and thickness of the film vary significantly during charge/discharge cycles o Large portion of electrolyte decomposition products diffuse away from the surface in the electrolyte – possible cross-talk with the anode SEI · Prolonged exposure of LiNi 0.5 Mn 1.5 O 4 to EC/DEC/LiPF 6 leads to surface Ni 3+ depletion, Mn 3+ enrichment, and surface film formation of electrolyte decomposition products · Surface and interfacial instability of LiMnPO 4 and LiNi 0.5 Ni 1.5 O 4 likely precludes these materials from achieving commercial viability without developing better routes for stabilizing the active material bulk and surface structure · Fundamental study of interfacial processes on Sn electrode was completed · In situ studies revealed that the nature and kinetics of interfacial processes are strongly dependent on the electrode surface structure and electrolyte composition o Stable surface film never forms on Sn (001) in EC/DEC/LiPF 6 electrolyte. The electrocatalytic behavior of Sn (001) surface possibly accounts for large irreversible charge losses observed for polycrystalline Sn anode o Effective SEI layer forms on Sn crystal domains (100) o Electrochemical reduction of DEC most likely occurs on Sn (001) surface whereas reduction of EC is promoted on Sn (100) · Sn interface instability in organic carbonate electrolytes can be remedied by careful optimization of Sn electrode surface design, electrolyte composition, and use of additives that (re)produce a stable SEI layer · It is critical for the long-term electrochemical performance of intermetallic anodes to suppress unwanted surface reactions. Coordinated electrode and electrolyte design must be carried out to achieve interfacial stability of Sn anodes in Li-ion battery applications. Future Directions · Design and apply in situ and ex situ experimental methodologies to detect and characterize surface processes in Li-ion intermetallic anodes o Comprehensive fundamental in situ spectroscopic ellipsometry in conjunction with AFM and FTIR/Raman surface analysis studies of the SEI layer formation on model monocrystal Sn and Si electrodes will be carried out o Cooperate with the BATT Task Group "SEI on Alloys“ and industrial partners (3M) to investigate the effect of material structure, morphology on formation of the SEI layer o Investigate correlations between physicochemical properties of the SEI layer and longterm electrochemical performance of Li-ion electrodes · Diagnostic evaluation of detrimental phenomena in high-voltage (>4.3 V) cathodes o Apply in situ and ex situ Raman and FTIR spectroscopy to detect and characterize surface and bulk processes in high voltage cathodes o Evaluate the effect of electrode passive additives and impurities on the electrochemical performance and long-term stability of the composite cathodes o Collaborate with BATT Task Group “Ni/Mn Spinel“ and industrial partners (HQ, Dow Chemical) to investigate detrimental processes that impede commercialization of new cathode materials · Develop and introduce new in situ instrumental techniques and experimental methodologies to study mass and charge transfer processes in Li-ion systems o Improve sensitivity, selectivity and achieve subwavelength spatial resolution in optical microscopy/spectroscopy o Acquire, adapt and introduce near-field technques to our diagnostic effort FY 2011 Publications/Presentations 1.
