10 years of operation on 1 battery?




Xeno Lithium batteries offer high capacity at extremely low self-discharge and are able to supply your device for many years.

10 years of operation on 1 battery

Primary Lithium batteries (Lithium thionyl-chloride, LiSOCl2) represent batteries with the highest energy density (Wh/kg), moreover able to operate without problems even in strong frosts. Perhaps their only technical “drawback” is the fact, that they´re only suitable for appliances with low current demands (up to tens of mA). However this “drawback” is already considerably overcome, because with modern components it´s easily possible to design devices with miliWatts power consumption. In principle are the Lithium primary (non-rechargeable) batteries suitable for backup (for example memories) and for power supplying devices with low power consumption, where it´s possible to reach even more than 10 years lifetime. This is naturally a huge benefit, as it enables to construct a device fully independent from external power supply, or without necessity of an external power supply and similar. At the same time it will also eliminate necessity to use an adapter or further electric installation.

These Lithium batteries operate on a principle of reaction Li+SOCl2. Arrising LiCl film on an anode has insulating properties. It provides excellent storage properties and energy preservation, because this passivation layer blocks auto reaction of Li+SOCl2 (self-discharging). Properties of Lithium batteries are also affected by the way and the length of stocking, and it´s possible, that after loading a battery, a short-time voltage drop will occur because of this passivation layer. Maximum capacity usage can be reached at a certain range of discharge currents (according to a diagram at every battery type). If a Lithium battery is intended to supply circuits with a short-time pulse demands, it´s very suitable to use a large capacitor or a supercapacitor connected in parallel with a battery. A capacitor in these cases will supply a bigger energy amount for a fraction of time and from the battery point of view a circuit then appears as one with significantly lower power consumption peaks. This contributes significantly to a maximum capacity usage and it´s also beneficial for a device itself thanks to minimum voltage drop at pulse power consumption.
