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.

TruSpin

TruSpin are an early-stage company based in Birmingham, Alabama making nanofiber products with AC electrospinning. IDTechEx spoke to the CEO, Robert Agnew, about TruSpin's technology and product range, focussing especially on its silicon nanofiber products for Li-ion battery anodes and ceramic nanofibers for heat-resistant PPE.

Zenlabs Energy Inc

Zenlabs are a start-up developing Li-ion batteries which utilise silicon oxides at the anode. They presented their developments at the IDTechEx Show USA 2019.

Airbus partners with Amprius on energy density battery tech

Airbus Defence and Space has partnered with U.S. based Amprius Inc's current equity funding. This financing will further boost the development of new generation batteries based on Silicon Nanowire Anode technology.

Summary from NAUM 2019 - Nanomaterials in energy storage

NAUM (from Nano Augmented) is a conference on nanomaterials organised and run by OCSiAl. IDTechEx attended a session on the use of nanomaterials in energy storage applications, and visited the exhibition.

Amprius' silicon nanowire lithium ion batteries power Airbus Zephyr

Amprius Inc is supplying advanced lithium ion cells to the Airbus Defence and Space Zephyr Program. Using Amprius' cells, which contain a 100% silicon anode, the Zephyr S flew more than 25 days, setting a new endurance and altitude record for stratospheric flight.

A new battle of the currents takes center stage

This coming November 14-15 at the Santa Clara Convention Center, leading players in the battery and energy storage industry will compete to capture the audience's attention over what technology is set to dominate in the coming decade.
