Solid state battery targets IIoT applications

Battery pioneer Ilika Technologies has launched what it says is the first solid state device designed for use in hostile environments. The P180, the second member of the Stereax family, is suitable for applications which operate in temperatures ranging from -40 to 150°C.

According to CEO Graeme Purdy, the industrial IoT (IIoT) is a ‘big sector and worth addressing’. “There’s a range of predictions about the growth in the IIoT, but one suggests demand of the IIoT in China is growing more quickly than that country’s consumer IoT sector.”

Purdy pointed to a number of subsectors, including industrial, aerospace, automotive and medical. “Batteries for these applications will have to meet a range of requirements if they are going to be useful,” he said. “Apart from being compact, having a long life and simple to use, they also need to be suitable for retrofitting.”

The P180 – which measures 10 x 10mm and is less than 1mm thick – has a capacity of 180µAh and has an operational voltage range from 3 to 3.8V, with a continuous current capability of 1.8mA. Amongst the differences between the P180 and the M250 introduced in 2016 is a different electrolyte and encapsulant.

Purdy said the P180 is not the end of the story for Ilika. “We have more launches planned for the end of 2017 and into 2018. We are looking to store more energy in a given footprint and are exploring miniaturisation. For the latter, we have had interest shown by companies looking to integrate batteries into components so the power supply is in the same footprint as, for example, a MEMS device. Other potential applications include powering implantable medical devices,” he concluded.
