Abstract

Enerize Li-Ion batteries technologies deliver higher energy and safety, while have a lower cost using Enerize silicon based binder free anode, binder free cathodes, solid inorganic electrolyte formulation, innovative equipment for thin film batteries production, and manufacturing technologies High energy silicon – graphite composite anodes are fabricated via a proprietary method of gas detonation deposition, do not require a polymer binder. The method and equipment for fabricate the anode based on Si-graphite composition ensure high level of the adhesion between composition and current collector, and cohesion between the particles of silicon and graphite. As a result, anode has high energy and stability during cycling. During presentation will be presented results of the results of evaluation of the dynamics of changing the diffusion coefficients of lithium cations in the solid phase of the anode material, and the change of the kinetic parameters of the electrochemical reaction during cycling Novel vitreous high ionic conductivity solid inorganic electrolyte with high operating rage of the temperature, up to 300° C, enables new design of lithium batteries, including micro- & macro-batteries, with safe charge/cycling, wide operating temperature range, and flexible formats. Enerize's solid electrolyte has high level of chemical stability in contact with electrode materials, and electrochemical stability in a wide range of working potentials (up to 5.0 Volts). Key innovating methods and equipment for thin film deposition are based on the Gas Discharge Electron Gun with a Cold Cathode, and Gas Detonation Deposition, which provide the high rate deposition of thin layers of electrode materials and solid electrolytes with predetermined properties. Non-destructive non-contact electromagnetic, ultrasonic, holographic interferometry, gas discharge visualization, and combined methods and equipment developed by Enerize, are innovative tools for evaluation, control and maintenance of high quality and reliability of initial materials, including next generation materials, semi-product, final product, and technologies during Li-ion battery manufacturing, including in-line control During the presentation we will discuss: a) correlation between composition, structure and electrochemical properties of electrolyte and electrodes, b) equipment for high rate deposition of thin layers of electrode materials and solid electrolytes with predetermined structural, morphological, and electrochemical properties. Synergetic effect of new materials, technologies and equipment for thin film deposition reduces costs, increases productivity of battery fabrication, and provides reliability and high performance of batteries. Areas of applications of solid state batteries include: electric vehicle; aerospace related equipment; hybrid systems batteries / solar cells; oil & gas drilling, and deep
