Abstract:

The solid-electrolyte interphase (SEI) considerably affects the performance and lifetime of lithium-ion batteries. Although the SEI has been investigated for many years, various central aspects of this thin passivation layer are still ambiguous due to its generic complexity. Therefore, we thoroughly investigate the growth mechanisms and the mechanical behavior of the SEI. The long-term growth of the SEI is the main reason which determines the shelf-life of state-of-the-art lithium-ion batteries. Nonetheless, the relevant transport mechanism responsible for the continued growth of the SEI is st

Abstract:

Silicon is novel Li-ion battery anode chemistry with exceptional theoretical energy densities. However, this alloying material has significant challenges with non-passivating solid-electrolyte interface (SEI) formation and significant chemo-mechanics issues. These issues have been studied extensively at the particle-level. However, extensive SEI formation and dynamic particle chemo-mechanics need to be accounted for when designing the overall electrode microstructure. For example, Si particle expansion can result in electrolyte pore-closure. During charging (Si lithiation), Si particles near t

Replacing graphite anodes with silicon can potentially increase cell energy by >20%. Performance of high-energy cells based on silicon was historically limited by mechanics, as Si particles would experience extensive fracturing that led to capacity fade.

Abstract:

Much of the silicon anodes for lithium ion batteries literature concentrates on the volume expansion of silicon leading to poor cycle life. Recently, the poor calendar life of silicon has become more of a focus. Calendar aging is typically measured by long periods of open circuit voltage (OCV) that are intermittently interrupted with a reference performance test (RPT) to quantify performance and capacity fade.

Abstract:

Silicon has attracted a lot of attention as anode material in lithium ion batteries due to its high practical capacity (around 3579 mAh.g-1 at Li15Si4 phase [1]). The main drawback for the use of Silicon is its significant volume expansion around 300% in fully intercalate state which causes particles pulverisation, dynamic formation of the solid electrolyte interface (SEI), losing electrical contact and capacity loss.[2] The solution is hidden in using silicon composite instead of pure silicon, [1,3] applying partial lithiation or delithiation process,[4] and improving the electrical particles

Silicon with high abundance and high gravimetric capacity around 3579 mAh.g-1 at Li15Si4 fully lithiated state [1] is one of the attractive anode materials in lithium-ion batteries. Volume expansion of around 300% in the fully intercalated state is the Achilles’ heel of silicon, causing particle pulverisation, continuous formation of solid electrolyte interface (SEI), loss of electrical contact and capacity loss.[2] The use of silicon composite instead of pure silicon, [1,3] limited de/lithiation,[4] and boosting the electrical connection between particles by applying optimal external pressure

Abstract:

With increasing demand of high energy density lithium ion batteries, silicon (Si) based anodes are an obvious substitute of graphite based systems due to their high capacity. However, large volume changes of Si during lithiation and delithiation processes causes pulverization of silicon particles. The resulting reduction in electrical continuity and solid electrolyte interphase (SEI) growth within the anode leads to a fast depletion of lithium reservoirs and an accelerates battery failure.

Lithium-ion batteries play a significant role in modern electronics and electric vehicles.

To boost the overall energy density while ensuring the safety of Li batteries, researchers have focused on developing the battery materials [1]. Silicon has an ultrahigh theoretical capacity and has been regarded as the best choice for next-generation lithium-ion battery anodes, but it also suffers from dramatic expansion during cycling [2].

Abstract:

In this work, we report direct/in situ measurements of stress and potential evolution during self-discharge of a fully lithiated silicon electrode. Parasitic reactions, typically attributed to the formation of the solid-electrolyte-interphase (SEI) layer on the surface of the silicon electrode, cause the self-discharge leading to the loss of cyclable lithium ions from the electrode and irreversible capacity loss. These parasitic reactions continuously occur when the electrode potential is below the equilibrium potential (typically 0.8V vs. Li/Li+) for SEI formation, and when the surface is ele

Silicon has long been considered a prospective anode material for lithium-ion batteries (LIBs) due to its high theoretical specific capacity and natural abundance. However, silicon is known to suffer from significant volumetric expansion (~ 400%) during lithiation and de-lithiation. The induced mechanical stress leads to pulverization of silicon as well as electrolyte consumption, which results in poor coulombic efficiency, high irreversible capacity loss and cell failure(1-3).

An attractive approach to increase the Li+-storage capacity of anode materials in Lithium-ion batteries (LiBs), is to replace or combine the routinely-applied graphite (372 mAh g-1) with higher-capacity materials. Among others, silicon (Si) with a theoretical capacity of 3579 mAh g-1 is a promising candidate [1]. Silicon is not yet been used as an anode material in its pure form, due to its low conductivity and volume increase of up to 300 % during lithiation. This two-step expansion (1st: Si + 2 Li+ + 2 e- → SiLi2.0; 2nd: SiLi2.0 + 1.5 Li+ + 1.5 e- → SiLi3.5) is a source of mechanical stress

Si anodes have become popular in battery research due to its high theoretical capacity (3500 mAh/g) and storage capacity of a single silicon atom which is 4.4 Li atoms. This phenomenon increases the volumetric energy density of the battery. However, Si atoms undergo too much volumetric change (%300 expansion) during Li intercalation/deintercalation (charge/discharge) that leads to unstable solid-electrolyte interface (SEI), and pulverization of Si atoms). These disadvantages results with rapid capacity fading [1,2]. Traditionally, the role of binders has been as a soft matrix backbone that all

Silicon is a promising active material for Li-ion battery negative electrodes because of its high theoretical specific capacity as compared to the standard graphite materials (3579 mAh/g vs 372 mAh/g).

The primary sources of this capacity fade are the delamination of the anode material from the current collector, the isolation of active material, and uncontrolled solid electrolyte inte
