Niobium in Batteries

niobium

Niobium-Based Anode Toshiba Super Charge ion Battery (SCiB) [5] have a Niobium Titanium Oxide anode and have improved performance: Downside: Cycle life, charging and cold performance are all improved, but the energy density (both gravimetric and volumetric) is significantly lower than most other Lithium-ion chemistry. NTO has roughly three times higher theoretical volume capacity density … 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 High … 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

NMC 9.5.5 for Li Ion Batteries

NMC 9.5.5 for Li Ion Batteries

Synthesis, Scale up, and Optimisation of NMC 9.5.5 for Li-Ion Batteries. Ethan Williams, David Burnett, Peter Slater, Emma Kendrick School of Metallurgy and Materials, University of Birmingham, Elms Rd, Birmingham B15 2SE Abstract LiNi0.9Mn0.05Co0.05O2 (NMC-955) have been synthesized by a coprecipitation reaction followed by a two step firing process. Increasing the firing load and tuning … Read more

Self Discharge of Cells

self discharge

Self discharge of cells is dependent on the chemistry, temperature and age of the cell. These reactions occur in any electrochemical systems and are very difficult to avoid completely. This is because some self discharge reactions involve chemical reactions which will always take place at a rate proportional to temperature. However, this does mean the … Read more
