Ilika revolutionises solid-state battery technology for IoT

As IoT devices move from concept to reality, there is an urgency of enabling long life, energy-efficient power sources. Ilika, a provider of solid state battery technology recently launched its Stereax M250 solid state battery, a new, miniaturised solid state battery technology for IoT devices.

Solid state batteries are key to IoT since they can be used in conjunction with all the current energy harvesting technologies whilst being able to match the energy needs for IoT devices. Many IoT devices need power in short bursts to collect and transmit data, whilst being able to support a wide range of environment temperatures. Relative to standard lithium ion batteries, solid state batteries have lower leakage currents (10x smaller) and longer life spans of up to 10 years (4x longer). They can also be integrated with other electronic components, thus keeping the size of the end device to a minimum.

"Many IoT devices will be deployed in places that are difficult to service on a regular basis so self-sufficiency is critical," said Charlene Marini, vice president, segment marketing, ARM. "Ilika's Stereax batteries can help as the technology will enable 'leave for life' IoT devices capable of producing data over extended periods with minimal maintenance. This is where the IoT starts to shed the power tether that could restrain its spread into new and exciting off-grid applications.
