Neocarbonix Boosts Energy Density 30% By Killing Polymer Binders

• https://insideevs.com by Gustavo Henrique Ruffo

When we talk about battery advancements, the ones that come to mind first are new chemistries and solid-state batteries. What if current cells could see a boost of up to 30 percent in energy density? That would allow 18650 and 2170 batteries – currently between 240 Wh/kg up to 270 Wh/kg – to reach more than 350 Wh/kg. This is what Nicolò Brambilla, CTO at Nanoramic, says Neocarbonix can do.

If you make the calculations based on 240 Wh/kg, the increase almost reaches 50 percent. When you take 270 Wh/kg as a reference, there's a gain of almost 30 percent. Translate that into range improvements in an electric car, and you'll see that is very desirable. 

Neocarbonix is a composite electrode. According to Brambilla, it achieves that in a way that may sound simple but has certainly made engineers and scientists lose some nights of sleep. The trick is to get rid of polymer binders and primers.

"You can think of Neocarbonix as a process to form a carbon structure in electrodes that is both the binding agent and conductive additive, thus brings significant cost and performance benefits. All this in a conventional scalable factory."
