SEI and Interphases at Electrodes

Role of surface oxides in the formation of solid-electrolyte interphases at silicon electrodes for lithium-ion batteries.

Nonaqueous solvents in modern battery technologies undergo electroreduction at negative electrodes, leading to the formation of a solid-electrolyte interphase (SEI). The mechanisms and reactions leading to a stable SEI on silicon electrodes in lithium-ion batteries are still poorly understood. This lack of understanding inhibits the rational design of electrolyte additives, active material coat...

SEI-based Process Improvement Efforts at Digital

The Software Engineering Institute is chartered with advancing the state-of-the-practice of software engineering to improve the quality of the systems that depend on software. Digital has based its software process improvement program on the Capability Maturity Model and Software Process Assessment developed by the SEI. As software organizations gain process maturity, they produce higher-qualit...

Voltammetry at Micro-Mesh Electrodes

Neste trabalho investigamos a voltametria em eletrodos do tipo micromesh. Em experimento de duração suficientemente curta, os eletrodods de trabalho micromesh se comportam primeiramente como uma rede de eletrodos de microbanda, seguido pelo comportamento esperado para um arranjo de eletrodos de micro-anel, independentes de difusão, com perímetro igual ao tamanho da grade. Durante eletrólise pro...
