Low power and/or low energy density belong to main limiting parameters of electrochemical energy storage devices. Increasing of the surface area between an electrolyte and an active electrode material is the way how to improve their charging rate capability. By means of the NanospiderTMtechnology prepared electrochemical materials can achieve a large specific surface area. Fibrous morphology, further, increases internal conductivity of the electrode and porosity improves transparency for ion mobility through electrode. These are other contributions of these materials to performance improvement. By means of the NanospiderTMtechnology variety of electrochemicaly active materials for Li-ion batteries or supercapacitors can be prepared. The Li4Ti5O12 spinel is an example of newly synthesized materials using electrospinning method. Due to zero-strain and fast lithium insertion this material is applicable as an anode in high rate and safety Li-ion batteries.
