Polyol Synthesis of Lithium Iron Phosphate with Carbon Nanotubes: Effect of Dispersion on Crystallinity and Electrochemical Performance
Published online by Cambridge University Press: 01 August 2014
Carbon nanotubes (CNTs) have been shown to be a viable conductive additive in Li-Ion batteries . By using CNTs battery life, energy, and power capability can all be improved over carbon black, the traditional conductive additive. A significantly smaller weight percentage (5% CNTs) is needed to get the same conductivity as 20% carbon black. Many of the previous efforts found that a combination of conductive additives was most advantageous . Unfortunately many of these efforts did not attend to the unique challenge that dispersing nanotubes presents and used non-optimal methods to disperse CNTs (e.g. ball milling) [3,4]. With poor dispersion a stable and resilient conductive network in the cathode is hard to form with CNTs alone. Here we investigate the formation of LiFePO₄ with CNTs using a polyol process synthesis.
