What is your minimum order quantity (MOQ), and can I get samples first?
Our MOQ is USD $500. Quantity depends on unit pricing. Yes, we offer samples for testing before formal orders.
What exactly is passivation in Li-SOCl₂ batteries?
Passivation is the natural formation of a thin Lithium Chloride (LiCl) layer on the lithium anode, reducing unwanted reactions and preserving battery life.
What are the effects of Li-SOCl₂ battery passivation?
Benefits:
- Very low self-discharge rate (shelf life over 10 years).
- Excellent long-term energy retention.
Drawbacks:
- Voltage Delay: Initial dip when discharging after storage.
How is the passivation layer removed (depassivation)?
- Apply a continuous discharge load to break the LiCl layer.
- Effectiveness depends on current level, battery size, and storage conditions.
My battery shows low voltage at first use. Is it defective?
No, this is typical. It’s due to passivation and will stabilize after activation begins.
How long does the initial voltage dip (delay) usually last?
It depends on storage duration and device power. Normally, a few seconds to minutes under load.
Can I reduce or avoid the initial voltage delay?
While passivation is natural, applying a consistent discharge load helps activate the battery and reduce voltage delay.
Does storage duration or temperature affect voltage behavior?
Yes. Longer storage and higher temperatures can increase the passivation layer’s thickness, slightly extending the voltage delay on activation.
