title: Lithium titanate aerogel for advanced lithium-ion batteries.
abstract: This work details the synthesis and characterization of a novel lithium titanate aerogel as an anode material for lithium ion batteries. Excessive loss of lithium during supercritical drying can be overcome by increasing the lithium precursor concentration during synthesis. Chronopotentiometry shows the aerogel to have a capacity about 80 % of theoretical at a symmetric C/3 rate, which is comparable to a commercial product. Cyclic voltammetry reveals a batt-cap behavior for the high-surface area aerogel, implying the potential for improved rate capability if electrical conductivity can be maintained.
