Concept and feasibility study of self-organized electrochemical devices

Since Volta's discovery of " an electric battery" in 1800, advancements have proceeded due to great materials advances. However, the basic configuration he proposed then is still present in today's portable power sources. In this work, using attractive and repulsive London-van der Waals forces, a self-organized, interpenetrating, separator-free rechargeable lithium ion battery called a self-organized battery system (SBS) is proposed. In this design, a repulsive interaction between the cathode and anode is used to establish the basic electrochemical junction. Increases in both energy density (Wh/kg, Wh/1) and power density (W/kg, W/1) are possible from such a design, due to 1) the decrease of inactive materials required, and 2) the decrease in Li ion diffusion length between the cathode and anode. The sign of the Hamaker constant (A₁₂₃) determines either attraction (+) or repulsion(-) where material 2 is the intervening material between materials 1 and 3.
