So, first of all, a little bit about Maxwell. Today the company consists of three different product groups, ultracapacitors, our microelectronics product group and our high-voltage capacitors. And we’ll spend just a little bit of time on microelectronics and high-voltage. But the majority of this presentation will be focused on our growth area which is ultracapacitors.
So first, our high-voltage capacitors, these are very large devices that are used in power distribution and transmission applications. These are designed and manufactured by our wholly owned subsidiary in Rossens, Switzerland, and our revenues for 2011 were just a bit north of $42 million.
Our microelectronics product group, these are electronics components in single-board computers that are designed and built to withstand the harsh effects of space environments. So, they’re basically radiation-mitigated parts that allow them to withstand the radiation effects of flying in satellites and other space applications. This is a niche product, very profitable for the company, and our revenues in 2011 were $18 million for these products.
So, as I mentioned, ultracapacitors will be the focus of the presentation. This is the growth area for the company. Today, we’re in many applications and that list continues to grow. We’ll cover some of these applications a little bit later in the presentation. Our revenues for this product group in 2011 were $97 million.So first, I’ll spend a little bit of time on talking about ultracapacitor and what an ultracapacitor does. And as Jed mentioned, an ultracapacitor is an energy storage device. It stores energy, and it’s capable of releasing that energy rapidly. So, it can take a quick charge and a quick discharge. They’re ideally suited for high-cycling, long-life applications such as regenerative braking in hybrid buses. So, first, this chart is designed to show some of the differences in the operating characteristics of ultracapacitors and batteries. On the horizontal axis, we’ve got the power density and on the vertical axis, we’ve got the energy density, which is storage capacity. And what this chart demonstrates is that batteries have a much higher energy density or storage capacity in comparison to ultracapacitors, which have a much higher charge-discharge rate.
