Cell Gas Pressure

Gases are generated in the cathode, anode and electrolyte during the formation and cycling of a battery cell. As this is a closed system the result is a cell gas pressure. What this gas is composed of, how it behaves and how it changes with State of Charge (SoC) and the cycling of the cell … Read more

Engineering Empty Space: Tailoring Battery Electrodes for Ion Transport

Author: Anton Resing The cathode layer in a lithium-ion battery is a composite of solid charge storing particles, a polymeric binder, and a conductive additive. Together, they are well dispersed in a solvent and spread like paint on a conductive substrate, an effective and pleasingly simple solution that works across various chemistries and cell designs. … Read more

10 things about SSBs that you are often not told

Author Dr. Simon Madgwick of Nuvvon Inc. As an overview, this post cannot cover every possibility or explain in depth. Nonetheless these 10 topics give a reasonable overview of solid-state batteries in terms of what is less transparent in the publicity and hype of solid state. To be clear, we need solid state batteries, but … Read more

Tesla 4680 Cathode Porosity

Indicative numbers for the Tesla 4680 cathode porosity, estimated based on 2D images of the Batch 1 and 2 cells originally analysed for The Limiting Factor by the Laboratory for Energy Storage and Conversion, UC San Diego. This image analysis and estimation was performed by Addionics based on the original Tesla 4680 cell benchmarking. Analysis … Read more

Niobium in Batteries


Niobium in batteries looks at the high level addition of this element and some of the claimed and measured improvements to the battery cells as a result. Niobium-Based Anode Toshiba Super Charge ion Battery (SCiB) [5] are developing a Niobium Titanium Oxide anode that will have improved performance over the current LTO products: Downside: Cycle … Read more

Lithium Titanium Oxide

Lithium Titanate

Lithium Titanium Oxide, shortened to Lithium Titanate and abbreviated as LTO in the battery world. An LTO battery is a modified lithium-ion battery that uses lithium titanate (Li4Ti5O12) nanocrystals, instead of carbon, on the surface of its anode. This gives an effective area ~30x that of carbon. The options for the cathode material are as varied. Advantages Disadvantages … Read more

Cell Sample Maturity

A B C D Sample development

Cell Sample Maturity is normally defined by the A, B, C, D sample definitions. These stages of the cell design, production line development and material supply are key to the relationship between the cell manufacturer and cell customer. The customer needs to have confidence in the cell design, robustness and quality and this is only … Read more
