Nanostructured Electrode Materials for Lithium-Ion Batteries
The use of nanostructured materials in lithium-ion batteries is reviewed with discussion of commercialization or potential for commercialization. Nanomaterials have the advantages of shorter distances for transport of ions or electrons and accommodation of strains associated with lithium insertion. These advantages enable the use of high-capacity electrode materials and offer the possibility of improved rate capability or cycle life. Nanostructuring has enabled the use of inexpensive, low-conductivity electrode materials, such as lithium iron phosphate and lithium titanate, and has resulted in the commercialization of batteries with these materials. Conversion-type electrode materials and lithium alloys, which offer significantly higher charge-storage capacity compared to conventional intercalation-type materials, have also been enabled by nanotechnology. The use of carbon nanostructures and carbon-based nanocomposites in lithium-ion electrodes is also discussed. © 2014 Elsevier B.V. All rights reserved..
