Exploring Silicon Anode Battery Material Technologies

This article provides an introduction into the key silicon anode materials being developed for Li-ion battery anodes, including silicon oxides, silicon-carbon composites, and 100% silicon anodes. These silicon anode technologies aim to improve battery performance whilst overcoming the poor cycle life historically typical for silicon anode materials.

Wright Electric: High Energy Density Batteries for Aviation

Wright Electric is a start-up working on high energy density aluminum air batteries and high power density motors for electrically propelled aerospace applications. This profile provides an overview of its key technologies.

Are Silicon Anodes the Key to Mass EV Adoption?

Maximizing energy density has been one key area of focus in electric vehicle battery development. Optimizations in cell and battery pack designs, alongside the use of higher nickel NMC and NCA cathodes, have led to steady improvement in battery energy density over the past 10-15 years.

5 Key Routes to Better Li-Ion Batteries

The current iteration of Li-ion batteries, which are based on graphite anodes, liquid electrolytes, and cathode materials such as NMC and LFP, are generally considered to be reaching their performance limits. However, from cell materials to battery designs, there are still several routes that can lead to further improvements in performance and cost.
