Lithium Batteries for Wireless Sensor Networks
نویسنده
چکیده
Non-rechargeable batteries with a life of 20 years and more are required today for many smart metering and AMR applications in the US. Tadiran's non-rechargeable lithium thionyl chloride batteries offer a proven life of 25 years. Kohler's new touchless commercial faucet was designed to run even 30 years on a hybrid lithium battery. Similar requirements exist for wireless sensor networks. They can be achieved by diligent optimisation of the power source. This optimisation rests on three pillars: capacity increase, decrease of self discharge and the minimisation of voltage losses. When pulse currents of up to 2.5 Amperes are required Tadiran's PulsesPlusTM technology, combining a secondary high rate element (Hybrid Layer Capacitor, HLC) with a primary high energy cell (3.6 Volts, 1340 Wh / dm) is the system of choice. The icing on the cake: Tadiran's TLI battery is a high-end highpower rechargeable element for use in combination with energy harvesting devices or other electrical low power energy sources.
