Conjugated Imine Polymer Synthesized via Step-Growth Metathesis for Highly Stable Silicon Nanoparticle Anodes in Lithium-Ion Batteries

Autor: Trevor Martin, Leah Rynearson, Mackenzie Kuller, Joseph Quinn, Chongmin Wang, Brett Lucht, Nathan Neale

We have developed a new method to synthesize polyphenylmethanimine (polyPMI) as a linear or a hyperbranched, conjugated polymer using an aldehyde-imine metathesis reaction. We detail the reaction mechanisms of this polymerization by characterizing a

Utilizing Triethyl Phosphate to Increase the Solubility of Lithium Nitrate for Improved Silicon Anode Performance

Autor: Leah L Rynearson, Leah Rynearson

Publikováno v: ECS Meeting Abstracts. :287-287

An electrolyte consisting of lithium nitrate (LiNO3) and lithium difluoro(oxalto)borate (LiDFOB) in ethylene carbonate (EC), ethylmethyl carbonate (EMC), and triethyl phosphate (TEP) was used to improve the long-term cycling stability of silicon anod

Evaluating the Effect of Electrolyte Additive Functionalities on NMC622/Si Cell Performance

Autor: Yeyoung Ha, Trevor R. Martin, Sarah Frisco, Leah Rynearson, Maxwell C. Schulze, Sang-Don Han, Stephen E. Trask, Brett L. Lucht, Glenn Teeter, Nathan R. Neale

Publikováno v: Journal of The Electrochemical Society. 169:070515

Unstable electrode/electrolyte interface is the major cause of degradation for silicon (Si)-based anodes for lithium (Li)-ion batteries. Development of functional electrolyte additives can provide a viable path toward stabilizing the dynamic Si/elect

Difluorophosphoric Acid Generation and Crossover Reactions in LiNixCoyMnzO2 Cathodes Operating at High Voltage

Autor: Chamithri Jayawardana, Nuwanthi D. Rodrigo, Leah Rynearson, Brett L. Lucht

Publikováno v: Journal of The Electrochemical Society. 169:060509

Cycling lithiated metal oxides to high potential (>4.5 V vs Li) is of significant interest for the next generation of lithium ion batteries as this significantly increases the capacity and energy of cells. However, cells cycled to high potential suff
