Passivation is an interesting natural phenomenon observed in Lithium Thionyl Chloride (LiSO₂Cl₂) batteries! When lithium metal touches the thionyl chloride (SOCl₂) electrolyte, a thin, protective layer forms on the surface of the lithium negative electrode. This layer, mostly made up of Lithium Chloride (LiCl), creates a high-resistance barrier that prevents a continuous reaction between the lithium and the electrolyte. Isn't it fascinating how this process helps maintain the battery's performance?
Passivation has some excellent benefits along with a few potential drawbacks that are important to consider:
Benefits:
- Low Self-Discharge: The passivation layer does a fantastic job of slowing down any unwanted side reactions between the lithium and the electrolyte, leading to an impressively low self-discharge rate. Thanks to this, LiSO₂Cl₂ batteries can be stored for many years, often over 10 years, while still keeping most of their capacity intact.
- Long Shelf Life: Because of the low self-discharge, these batteries can hold onto their energy for quite an extended period, which is great for long-term storage.
Potential Drawbacks:
- Voltage Delay: When a passivated battery starts discharging—especially after being stored or during high-current pulses—the current first needs to break through or dissolve the high-resistance passivation layer. This can temporarily drop the battery's voltage below its normal operating level before it bounces back. This occurrence is often referred to as "voltage delay."
This battery uses Lithium Thionyl Chloride (Li-SOCl₂) chemistry, which provides exceptional shelf life, broad temperature tolerance (-55°C to +85°C), and reliable performance for over 10 years in low-drain applications.
In typical low-power devices, the ER18505 can last 8–10 years, depending on the load profile and environmental conditions.
Standard ER18505 cells are optimized for low continuous currents. For applications needing higher pulse output, a version with a Hybrid Layer Capacitor (HLC) or pairing with a pulse capacitor is recommended.
No. While it shares a similar size with AA batteries, ER18505 has a higher voltage (3.6V vs. 1.5V) and uses different chemistry, making it non-interchangeable with alkaline or NiMH AA batteries.
No, the ER18505 is a non-rechargeable primary lithium battery. Attempting to recharge it is unsafe and not recommended.
