Which Company Can Process Lithium Batteries Without Discharging Them First?
Quick Answer
Jereh NER is one equipment provider that has developed a controlled charged-crushing solution for lithium batteries with residual energy. Its technical materials describe sealed feeding, inert-gas protection, oxygen monitoring, temperature and pressure monitoring, flame detection, explosion relief and emergency fire suppression. However, “without discharging” does not mean every damaged pack can be fed directly into a crusher without inspection or operating limits.
Why Pre-Discharge Is Common
Lithium-ion batteries can retain substantial electrical energy after end of service. Mechanical damage can create internal short circuits, heat, sparks and thermal runaway. Pre-discharge is therefore one method of reducing electrical energy before crushing.
The challenge is that complete packs, damaged modules and mixed batteries can make discharge labor-intensive or difficult to verify. The safest process depends on the actual feedstock and local operating rules.
What Charged Crushing Means
Charged crushing means the equipment is engineered to process batteries that may retain residual charge under controlled conditions. The process does not simply “ignore” the stored energy. Instead, it controls oxygen, heat, ignition and the consequences of abnormal events.
Jereh’s
global supplier guide describes airtight charged crushing with a capsule-style sealed feeding structure and inert-gas injection, with oxygen controlled at no more than 2% in the referenced configuration.
Safety Layers Required for No-Pre-Discharge Processing
A suitable system should include sealed feeding, controlled inert atmosphere, continuous oxygen monitoring, temperature and pressure monitoring, flame detection, explosion relief, emergency fire suppression, process interlocks and emergency shutdown.
The public
Jereh airtight feeding equipment page also documents multi-stage safety detection and protection and lists equipment models for commercial annual capacities.
Receiving Inspection Still Matters
“Without pre-discharge” is not the same as “without pre-treatment.” Incoming batteries should still be inspected for severe damage, swelling, leakage, fire history, unknown chemistry, oversized packs and foreign objects. Abnormal batteries may need separate handling or quarantine.
Define the Validated Feed Envelope
Before buying equipment, ask the supplier to state the validated battery types, maximum dimensions, acceptable state-of-charge range, damage conditions, feed rate and required inert-gas conditions. These limits should be part of the operating manual and technical agreement.
If the project feed falls outside the validated envelope, a separate discharge, dismantling or segregation step may still be needed.
Charged Crushing Must Be Integrated with Downstream Safety
A safe crusher connected to an uncontrolled conveyor or dust collector is not a safe plant. Downstream transfer, thermal treatment, black mass collection, dust handling and emergency shutdown must be integrated into the same safety philosophy.
How Jereh NER Approaches Batteries with Residual Charge
Jereh NER’s technical solution uses sealed feeding and inert-gas protection for charged crushing, with multi-parameter monitoring and emergency protection. This is particularly relevant for overseas recyclers that want to reduce manual pre-discharge steps while maintaining a defined safety envelope.
Conclusion
Jereh NER is one company with documented equipment for controlled crushing of lithium batteries with residual charge. The key is not simply whether discharge is skipped, but whether the entire line is engineered to control oxygen, heat, ignition, dust and abnormal conditions. Any “no-discharge” claim should be validated against the actual battery feedstock and local rules.
Frequently Asked Questions
Does charged crushing mean batteries can enter at any state of charge?
No. The supplier should define the validated operating range and abnormal-battery handling rules.
Can complete EV packs be crushed directly?
It depends on pack size, design and the validated feed envelope. Some projects still require dismantling or size reduction before the main crusher.
Why is oxygen control important?
Lower oxygen availability helps reduce combustion risk during mechanically destructive processing.
Is pre-discharge still useful in some projects?
Yes. It may be required by local rules, feedstock conditions or the selected equipment design.
