Electrolyte Fill Requirements

Lithium ion cell

What are the electrolyte fill requirements for a cell versus chemistry, capacity, format, lifetime and other parameters? The electrolyte is the medium that allows ionic transport between the electrodes during charging and discharging of a cell. Electrolytes in lithium ion batteries may either be a liquid, gel or a solid. Lithium batteries use non-aqueous electrolytes … Read more

Lithium Rich Manganese

Lithium Rich Manganese (LRM) has a high specific capacity because of both cationic and anionic redox activity and are expected to be developed and applied as cathode materials for a new generation of high-energy density lithium-ion batteries [1]. Quan Li et al [2] show that increasing LRM loading mass to 10 mA⋅h⋅cm−2 (calculated by 300 mA⋅h⋅g−1) and … Read more

Comparing Cell Energy Density of Two Chemistries

This case study will highlight the importance of reporting new electrode active material performance parameters in full cell architectures. It will also discuss the need to understand the limits of different cell chemistries, and why any extrapolation of future performance must take into account the physical realities of the materials. The performance of electrode active … Read more

Lithium Intensity of Solid-State Batteries

In the ever-evolving world of lithium-ion batteries, solid-state batteries (SSB) are seen as the next generation of lithium-ion batteries. In an SSB, the liquid electrolyte used in conventional lithium-ion cells is replaced by a solid electrolyte capable of conducting lithium. There are three main families of solid electrolytes: oxides, sulphides, and polymers. SSBs promise to … Read more

Impact of Formulation and Slurry Properties on Lithium-ion Electrode Manufacturing

Impact of Formulation and Slurry Properties on Lithium-ion Electrode Manufacturing

The impact of formulation and slurry properties on lithium-ion electrode manufacturing is significant. The combination of materials in the electrodes, including the active material, conductive additive, and binders, plays a crucial role in determining the characteristics and performance of LIBs. Dr. Carl Reynolds, Dr. Mona Faraji Niri, Dr. Marc Francis Hidalgo, Robert Heymer, Dr. Luis … Read more

Dry vs Wet Separator Technology

ZIMT battery separator

A look at dry vs wet separator technology and a look at the next developments in the roadmap. Author: Paul Wen from ZIMT The separator is a porous membrane placed between electrodes of opposite polarity, permeable to ionic flow but preventing electric contact of the electrodes. The dry vs wet differentiation is essentially the difference … Read more

Knee Point

Battery Capacity versus number of cycles showing the Knee Point

Attia et al [1] also describe six mechanisms/pathways that can produce the “Knee Point”: The impact of this nonlinear degradation in cell capacity depends to some extent on the architecture and application, but includes: This post has been built based on the support and sponsorship from: Eatron Technologies, About:Energy, AVANT Future Mobility, Quarto Technical Services, TAE Power Solutions and The Limiting Factor.  … Read more

Anode-Cathode

Ande and cathode deifinition in chemistry

When a battery is discharging the electrons, e– , move from the – to + terminal and while it is charging the electrons travel from the + to the – terminal. Both, during the discharge and recharge electrons move from the Anode to the Cathode. {Anode and Cathode swap places}. These electrons are generated by … Read more
