EFFI­CI­ENT VACU­UM DRY­ING FOR LITHI­UM-ION BAT­TE­RIES

Dis­co­ver our envi­ron­men­tal­ly fri­end­ly and safe method for vacu­um dry­ing lithi­um-ion bat­te­ries that rede­fi­nes qua­li­ty and effi­ci­en­cy in the recy­cling pro­cess.

PIO­NEE­RING DRY­ING TECH­NO­LO­GY: THE RET VACU­UM DRY­ER

No dry­ing, no flamma­ble elec­tro­ly­te

Crea­te the ide­al basis for the best black mass qua­li­ty with the low-emis­si­on reco­very of elec­tro­lytes.

Reckel­ber­g’s vacu­um dry­ing tech­no­lo­gy offers a pio­nee­ring solu­ti­on that not only impro­ves the safe­ty and envi­ron­men­tal com­pa­ti­bi­li­ty of your recy­cling pro­cess, but also makes a signi­fi­cant con­tri­bu­ti­on to cost effi­ci­en­cy and mate­ri­al reco­very. By inte­gra­ting our inno­va­ti­ve dry­ing into your ope­ra­ti­ons, you can maxi­mi­ze the reu­se of valuable raw mate­ri­als while streng­thening your mar­ket posi­ti­on.

High­lights

Safe­ty

Safe and low-emis­si­on reco­very of vola­ti­le orga­nic elec­tro­lytes

Qua­li­ty

Low tem­pe­ra­tures in the vacu­um dry­er ensu­re high-qua­li­ty black mass

Fire risk mini­miza­ti­on

The dry­ing pro­cess dra­sti­cal­ly redu­ces the fire risk of the bat­te­ries

Increased effi­ci­en­cy

More effi­ci­ent pro­ces­sing and mate­ri­al reco­very, e.g. through par­al­lel red­un­dant dry­ing

EFFI­CI­ENT INER­TING AND GRAIN SIZE OPTI­MIZA­TI­ON

Lithi­um-ion bat­te­ries requi­re careful dry­ing after dischar­ge in order to effec­tively iso­la­te the flamma­ble elec­tro­ly­te. At Reckel­berg Envi­ron­men­tal Tech­no­lo­gies, we offer modern vacu­um dry­ers for a tried and tes­ted pro­cess. The bat­te­ries to be pro­ces­sed can be iner­ted through an advan­ced air­lock sys­tem. Sub­se­quent­ly, a four-shaft rotor shear ensu­res an opti­mal grain size and thus gua­ran­tees the qua­li­ty of the recy­cling pro­cess.

In the next pha­se, our RET vacu­um dry­ers are used. The­se dou­ble-wal­led hori­zon­tal padd­le dry­ers are desi­gned to effi­ci­ent­ly vapo­ri­ze the vola­ti­le orga­nic bat­tery elec­tro­lytes. Thanks to the high-per­for­mance vacu­um sys­tem, dry­ing takes place at low tem­pe­ra­tures, which increa­ses the safe­ty of the pro­cess and impro­ves the qua­li­ty of the end pro­duct.

SUS­TAINABLE RECO­VERY AND EMIS­SI­ON CON­TROL

As the pro­cess con­ti­nues, the dry­er coll­ects and con­den­ses the vapo­ri­zed elec­tro­lytes using an inno­va­ti­ve mul­ti-stage heat exch­an­ger sys­tem. This pro­cess enables the elec­tro­lytes to be effi­ci­ent­ly coll­ec­ted and bot­t­led in liquid form, allo­wing the valuable resour­ce to be reco­ver­ed and retur­ned to the cir­cu­lar eco­no­my.

Final­ly, our sophisti­ca­ted exhaust air puri­fi­ca­ti­on sys­tem ensu­res that emis­si­ons remain con­sis­t­ent­ly below the strict EU limits. In addi­ti­on, the sys­tem auto­ma­ti­cal­ly opti­mi­zes the dwell time and the dry­ing pro­cess to achie­ve an ide­al result with mini­mi­zed inert gas con­sump­ti­on. Once dry­ing is com­ple­te, the cell com­pon­ents are ide­al­ly pre­pared for fur­ther pro­ces­sing.

ENT­RY INTO ELEC­TRO­LY­TE RECO­VERY

What the vacu­um dry­er does in prac­ti­ce

A recy­cling ope­ra­tor based in Eas­tern Euro­pe has deci­ded to use RET vacu­um dry­ing to remo­ve the elec­tro­lytes con­tai­ned in pre­vious­ly shred­ded bat­tery mate­ri­al from dischar­ged and dis­mant­led lithi­um-ion bat­te­ries, thus ensu­ring safe pro­ces­sing in mecha­ni­cal tre­at­ment.

Facts about the pro­ject

Uni­form dry­ing of the cell com­pon­ents and par­al­lel red­un­dant dry­ing

Fact 3 Qua­li­ty

Gent­le hea­ting for best black mass qua­li­ty

Fact 4 Safe­ty

Dra­stic reduc­tion of the fire load
