Why is thionyl chloride not used in lithium batteries?
Unlike other lithium primary cells, the lithium thionyl chloride cell undergoes a chemical reaction between the lithium anode and the electrolyte. As a result, a protective film forms over the lithium anode, which impedes the ion flow between the anode and cathode.
How long do Lithium thionyl chloride batteries last?
10 to 20 years
With low self-discharging of 1-2% per year, these batteries are expected to last at least 10 to 20 years, depending on the specific load profile of the application.
What is Li SOCl2 battery?
Lithium thionly chloride batteries have a lithium metal anode and thionly chloride(SOCl2) as active cathode; it has the highest specific capacity and specific energy in all practical chemical power sources and is widely used as a new energy system in electronic devices.
What is the specification of lithium ion battery?
Though the nominal voltage of lithium ion cells with different chemistries varies between 3.2 to 3.7 V (with the exception of Lithium Titanate cell which has the nominal voltage of 2.4 Volts), the charging voltage of lithium cells is usually 4.2V and 4.35V, and this voltage value may change with the different …
What is a limno2 battery?
Lithium – Manganese Dioxide Battery (Li-MnO2) deliver high voltage, high specific energy, low internal resistance, and a stable discharge curve. It’s preferred as a standby battery. They deliver a voltage of 3.0 V and are cylindrical in shape, in 1/2AA to D format.
Can a lithium battery last 15 years?
These batteries are constructed in two different ways: spirally wound batteries, which offer a maximum service life of approximately 10 years; and bobbin-type cells, which are the only lithium batteries that can deliver 25+ years of service life.
What is the specification of battery?

Is thionyl chloride flammable?
FIRE HAZARDS * Thionyl Chloride may burn, but does not readily ignite. * Use dry chemical extinguishers. * DO NOT USE WATER. * POISONOUS GASES ARE PRODUCED IN FIRE, including Hydrogen Chloride and Sulfur Oxides.
Can LiMnO2 batteries be recharged?
Commercially available LiMnO2 Battery is marked with the words “charging prohibited” on the outside, emphasizing that this type of battery is not rechargeable.
How do you dispose of LiMnO2 batteries?
Until such time that regulations or specified guidelines are issued, the following is recommended for the disposal of DURACELL Li/MnO2 cells and batteries. Batteries in Household Use Individual cells and batteries can be disposed of with other household waste, but in compliance with local regulations. .
What is C rate in Li ion battery?
A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps.
