The com­pa­ny’s patent­ed tech­nol­o­gy plat­form is based on con­trolled growth of car­bon nanofibers (CNF), which enables advanced com­po­nent solu­tions with high per­for­mance and low mate­r­i­al con­sump­tion. The tech­nol­o­gy is being devel­oped through the sub­sidiaries Smoltek Semi, which focus­es on ultra-thin capac­i­tors for the chip of the future, and Smoltek Hydro­gen, which devel­ops com­po­nents for cost-effec­tive pro­duc­tion of green hydrogen.

Through col­lab­o­ra­tions with Tai­wanese ITRI and Her­aeus Pre­cious Met­als, Smoltek has tak­en impor­tant steps towards indus­tri­al val­i­da­tion and future com­mer­cial agreements.

- We have built a strong tech­no­log­i­cal foun­da­tion and estab­lished part­ner­ships with lead­ing play­ers in our focus areas. Now it is about trans­lat­ing the tech­nol­o­gy into busi­ness. The rights issue gives us the oppor­tu­ni­ty to inten­si­fy work on cus­tomer projects, indus­tri­al­iza­tion and com­mer­cial­iza­tion, says CEO Mag­nus Ander­s­son.

The net pro­ceeds from the rights issue will be used, among oth­er things, for cus­tomer-dri­ven devel­op­ment, prod­uct adap­ta­tions, indus­tri­al­iza­tion, sales efforts and con­tin­ued research and development.

The rights issue con­sti­tutes the final step in the financ­ing plan that the board of direc­tors pre­sent­ed in Decem­ber 2024. The goal is to cre­ate the con­di­tions for pos­i­tive cash flow from 2027 and at the same time strength­en the com­pa­ny’s posi­tion in two mar­kets where the need for new mate­r­i­al and com­po­nent solu­tions is expect­ed to increase for many years to come.

Two solutions for a better tomorrow 

Smoltek address­es two glob­al macro trends – the ever-increas­ing com­put­ing pow­er of next gen­er­a­tion proces­sors, and the enor­mous demand for more ener­gy that fol­lows in its wake.

We enable the next gen­er­a­tion of power.:

1. Smoltek Semi offers ener­gy- and cost-effi­cient capac­i­tors with high elec­tri­cal per­for­mance for pow­er sup­ply for AI and HPC proces­sors and for Radio Fre­quen­cy and Optoelectronics.
2. Smoltek Hydro­gen offers PGM mate­r­i­al sav­ings and cost-effec­tive elec­trodes with high cat­alyt­ic per­for­mance for PEM elec­trolyz­er and fuel cells.

Smoltek Semi: CNF-MIM Capacitors – Stable Power Supply for Advanced Chips 

Smoltek’s CNF-MIM tech­nol­o­gy is specif­i­cal­ly devel­oped for sta­ble pow­er man­age­ment in AI chips and high-per­for­mance com­put­ing (HPC), data cen­ters, as well as RF appli­ca­tions and optoelectronics. 

The CNF-MIM capac­i­tor com­bines high capac­i­tance den­si­ty with low elec­tri­cal loss­es (ESL and ESR), pack­aged in an extreme­ly thin form fac­tor that enables advanced chip inte­gra­tion. Through cost-effec­tive man­u­fac­tur­ing, Smoltek Semi builds more ener­gy-effi­cient capac­i­tors, inde­pen­dent of sub­strate, for the next gen­er­a­tion of advanced chips.

Smoltek Hydrogen – Electrochemically stable and material-saving electrodes for hydrogen applications 

Smoltek’s porous trans­port elec­trode (PTE) con­tains only 0.1 mg irid­i­um per cm², but can pro­duce as much hydro­gen as a con­ven­tion­al poly­mer elec­trode, which requires many times more irid­i­um per cm². 

Our PTE tech­nol­o­gy has demon­strat­ed con­firmed elec­trode sta­bil­i­ty dur­ing irid­i­um reduc­tion. The tech­nol­o­gy has also been shown to pro­vide reduced con­tact resis­tance in elec­tro­chem­i­cal cells, which is an impor­tant fea­ture that pro­vides high­er effi­cien­cy and increased per­for­mance in both fuel cells and electrolyzers. 

Reduced con­tact resis­tance in a fuel cell (espe­cial­ly PEMFC – pro­ton exchange mem­brane fuel cell) is crit­i­cal for improv­ing per­for­mance and life. Con­tact resis­tance occurs pri­mar­i­ly at the inter­faces between cell lay­ers, for exam­ple between the gas dif­fu­sion lay­er (GDL) and the bipo­lar plate.

20 years of research and know-how in nanotechnology 

Our inno­va­tions are based on over 20 years of research and know-how in nan­otech­nol­o­gy. We have a broad patent port­fo­lio for exten­sive intel­lec­tu­al prop­er­ty pro­tec­tion that cur­rent­ly con­sists of 97 grant­ed patents with­in 21 families. 

In total we can count a total of more than 120 indi­vid­ual patent assets (patents applied for and grant­ed) cov­er­ing CNF syn­the­sis (con­trolled growth of car­bon nanofibers) as well as process­es and pro­duc­tion meth­ods at the appli­ca­tion level.

Additive manufacturing method 

Smoltek’s prod­ucts (capac­i­tors and elec­trodes) are man­u­fac­tured using addi­tive man­u­fac­tur­ing tech­nol­o­gy. It is an indus­tri­al tech­nol­o­gy in which three-dimen­sion­al objects are cre­at­ed by adding mate­r­i­al lay­er by lay­er. Unlike tra­di­tion­al machin­ing, which cuts away mate­r­i­al,
this method reduces waste and enables extreme­ly com­plex geome­tries, more mate­r­i­al vari­a­tions and faster pro­to­type manufacturing. 

In our case, this means that we grow car­bon nanofibers on a sur­face that is com­pat­i­ble with indus­tri­al elec­tri­cal and chem­i­cal process­es, and which are then coat­ed with dif­fer­ent met­als, atom­ic lay­er by atom­ic layer. 

The result is that we sig­nif­i­cant­ly increase the avail­able sur­face area for chem­i­cal and elec­tri­cal process­es, which enables the man­u­fac­ture of more com­pact and pow­er­ful appli­ca­tions in sev­er­al dif­fer­ent indus­tri­al sec­tors – appli­ca­tions that are more ener­gy and cost-efficient.

The benefits of additive manufacturing

• Com­plex design: Enables shapes that are impos­si­ble to man­u­fac­ture traditionally
• Mate­r­i­al effi­cien­cy: Less waste and scrap as only nec­es­sary mate­ri­als are used
• Cus­tomiza­tion: Per­fect for cus­tom components
