Advantages

Lithium-Thionyl Chloride Li-SOCI2Advantages:• High energy density• Low leakage• High Nominal OCV (open circuit voltage) 3.6V• Nonflammable• Wide operating temperature range.Disadvantages:• High internal impedance relative to other lithium batteries• Passivation layer grows quickly in case of high ambient temperature ( during shelf life).• Low current drawn form battery during the pulse ( despite very high energy) depends on battery type( bobbin or Jelly Role or spiral wound)• High price• Voltage delay phenomenon ( liquid cathode (6))Applications:• Military radio communication• Son buoys and other underwater applications• Emergency location transmitters beacon (ELTs, EPIRBs)• Cardiac defibrillatorsSuperCapacitor impact:• During shelf life SC drawing low current from battery decrease passivation layer reduce voltagedelay problems (2)• During pulse transmissions SC due to low ESR produces pulses prolong battery life time
