Solid state battery meets ‘fit and forget’ IoT device challenge
Addressing the key challenge of always-on, self-charging and efficient energy, Ilika’s Stereax M250 battery family will enable smaller, higher energy-dense batteries to accelerate IoT products to market.
As IoT devices move from concept to reality, providing small, energy efficient solutions for home automation, transportation and healthcare is now one of the key challenges. Ilika is aiming to empower wider adoption of IoT devices through a ‘fit and forget’ design that enables IoT sensors to be fitted without further maintenance, including changing batteries.
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).
“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.”
Ilika has taken the solid state battery concept to the next level of evolution with its expertise in material development. Ilika Stereax batteries use patented materials and processes enabling superior energy density per battery footprint, up to 40% improvement on current solid state solutions, and increased temperature range support to over 100°C, 30°C higher than existing solid state products. Ilika’s batteries do not contain any free lithium which makes them more moisture resistant.
Ilika is demonstrating the capability of the company’s first Stereax battery in its perpetual beacon for temperature sensing at IDTechEX in Berlin between the 27-28th April 2016.
