those in standard lithium-ion (Li-ion) batteries,with a silicon anode and a solid electrolyte composed of a lithiumbased pl


metallic lithiumprevents reactionwith moisture in the immediate environment thereby eliminating the risk of combustion. Second, the efficiency of the Stereax solid state battery is far beyond that of


commercially available technology It can be charge

advanced Li-ion products and can store twice the amount of en gyergy in the same volume. The absence of liquid components in this battery significantly reduces the leakage currentwhilst improving the operational lifetime to up to 10 years. As a result, the devices powere

This solid state technology incorporates a solid thin filmelectrolyte. Therefore, the battery does not need to be excessively encapsulated, allowing for considerable size reduction.

Stereax solid state energy storage is ready to meet the needs of the sensor and IoT market, but this is only the first step.Whilst current designs are focused on small applicationswith low ower requirements, work is being done to scale up the charge capacity and output to enable larger


owpow


applications to access the numerous benefits of solid state energy storage. Asmore pow


owerful solid state batteries


become available, itwill be up to device manufacturers to decide howto align innov


ovation in application design and


manufacturingwith the specifications and capabilities of a newgeneration of high performance port

solutions to provide the userwith a better and indeed safer experience.
