Since their introduction into the commercial marketplace in , lithium ion batteries have become increasingly ubiquitous in portable technology. Nevertheless, improvements to existing battery technology are necessary to expand their utility for larger-scale applications, such as electric vehicles. Advances may be realized from improvements to the liquid electrolyte; however, current understanding of the liquid structure and properties remains incomplete.

Lithium—sulfur cells present an attractive alternative to Li-ion batteries due to their large energy density, safety, and possible low cost.

Their successful commercialisation is dependent on improving their performance, but also on acquiring sufficient understanding of the underlying mechanisms to allow for the development of predictive models for operational cells. To address the latter, we present a zero dimensional model that predicts many of the features observed in the behaviour of a lithium—sulfur cell during charge and discharge.

It is shown that the flat shape of the low voltage plateau typical of the lithium—sulfur cell discharge is caused by precipitation.

During charge, it is predicted that the dissolution can act as a bottleneck, because for large enough currents the amount that dissolves becomes limited. This results in reduced charge capacity and an earlier onset of the high plateau reaction, such that the two voltage plateaus merge.

By including these effects, the model improves on the existing zero dimensional models, while requiring considerably fewer input parameters and computational resources than one dimensional models.

The model also predicts that, due to precipitation, the customary way of experimentally obtaining the open circuit voltage from a low rate discharge might not be suitable for lithium—sulfur.

This model can provide the basis for mechanistic studies, identification of dominant effects in a real cell, predictions of operational behaviour under realistic loads, and control algorithms for applications.

The nucleus includes three protons and four neutrons, according to ChemicalElements. The orbitals are like the layers of the onion that surround a solid core scientists call the nucleus. Only the outer layer of the onion turns brown as only the outer electron shells allow the atom to react.

Each of these shells has the ability to contain a certain number of electrons. With lithium, the two electrons fill the inner shell, but the outer shell has room for an additional seven electrons for a total of eight. With its almost empty outer shell, elemental lithium is highly reactive and does not occur in its free form in nature. In the chemical laboratory, the metal is stored in paraffin oil to reduce it reaction with water in the form of moisture from the air. Having your own site isn't required but models with member paysites are usually the best candidates for these as we both have an interest in creating strong sets for the sites.

These shoots aren't just about "getting the nudes" this is where most of my body of work comes from and I put everything I have into these shoots.

My recent Bizarre Magazine cover and feature with Mosh was pulled from one of these sets. Feel free to contact me if you want more information or have an idea. I am available for hire and my rates are very reasonable - you can call the shots and wear as little or as much as you like. I shoot men, portraits, clothed catalog work, press shots for bands, and just about any project I think is interesting and a good fit for me.

Feel free to contact me if you have a project or shoot to discuss. I still do limited trade shoots mentioned above but be advised that they usually involve tasteful nudity and the creation of commercially viable content sets for my sites, gallery, and print work.

I am no longer working with SuicideGirls, though I still shoot content for single girl sites and my own projects. I am currently unable to hire or shoot current or former SG models for portfolio or client projects. My magazine and book work often involves fashion or fine art shots with partial nudity - I do very few trade shoots if you contact me saying "I'd love to shoot with you" I will assume you are inquiring about hiring me or doing a content trade shoot.

My rates are very reasonable, please inquire if you have an interest in shooting with me. Also - be advised that I shoot nudes. I also shoot quite a bit of commercial, fashion and editorial work. I make an investment of my time and energy when I work with new models and I prefer to work with a core group that knows how I work.

I'm not hurting for new talent or models to work with I give most of my paid client castings to models that I work with, particularly those that shoot nudes for my other projects.

Given the choice of a model I can shoot both with and a model that only does non-nudes I'll usually chose to invest in and support the former.

This is a conversation about commercial viability of the images not my personal desire to get models naked. I've shot over models nude and in various states of becoming nude, this is my job and I'm a professional.

Shooting nudes hasn't ruined Kate Moss's modeling career and it probably won't ruin yours. I don't consider what I do porn. My rates are very reasonable if you have an idea or want to dictate the direction of the shoot please feel free to discuss it with me.

Side reactions and degradation processes may lead to a number of undesirable effects, causing capacity loss in lithium-ion batteries. Typically, aging occurs due to multiple complex phenomena and reactions that occur simultaneously at different places in the battery, and the degradation rate varies between certain stages during a load cycle, depending on potential, local concentration, temperature, and the direction of the current.

This tutorial demonstrates how to model aging in the negative graphite electrode in a lithium-ion battery, where a parasitic solid-electrolyte-interface SEI forming reaction results in an irreversible loss of cycleable lithium.

The model also includes the effect of increasing potential losses due to the resistance of the growing SEI film on the electrode particles, as well as the effect of a reduced electrolyte volume fraction on the electrolyte charge transport. This model example illustrates applications of this type that would nominally be built using the following products:. Furthermore, this example may also be defined and modeled using components from the following product combinations:.

Particular functionality may be common to several products.
