Amprius and Matternet Partner to Advance High-Density Cells for Commercial Drone Delivery

Amprius and Mat­ter­net have announced a strate­gic col­lab­o­ra­tion to advance the per­for­mance and eco­nom­ics of autonomous aer­i­al deliv­ery through high-ener­gy den­si­ty sil­i­con anode cells.

As a result, Amprius cells are now deployed in Matternet’s M2 air­craft, and the com­pa­nies are extend­ing their work to bat­tery solu­tions opti­mized for Mat­ter­net’s next-gen­er­a­tion plat­form.

As phys­i­cal AI moves into the real world — with small, elec­tric autonomous air­craft trans­port­ing goods through cities — bat­ter­ies are becom­ing a strate­gic dri­ver of plat­form per­for­mance. In drone deliv­ery, bat­tery per­for­mance shapes not only air­craft capa­bil­i­ty, but also net­work design, asset uti­liza­tion, and cost per deliv­ery.

Andreas Rap­topou­los, Founder and CEO of Mat­ter­net, said: “As the world’s lead­ing urban drone deliv­ery play­er, we part­ner with the best tech­nol­o­gy com­pa­nies in the world to push what’s pos­si­ble. Amprius deliv­ers best-in-class bat­tery per­for­mance, and in drone deliv­ery that trans­lates direct­ly into com­mer­cial advan­tage.

“Every addi­tion­al mile of range expands our net­work cov­er­age. Every minute saved in charg­ing increas­es fleet uti­liza­tion. And every gram saved can trans­late into greater pay­load capac­i­ty. With Amprius, we have the oppor­tu­ni­ty to engi­neer that tech­nol­o­gy around our air­craft, our net­work mod­el, and our cost-per-deliv­ery tar­gets.”

High-Ener­gy Den­si­ty Cells for Com­mer­cial Drone Deliv­ery

Amprius’ sil­i­con anode cells deliv­er up to twice the ener­gy den­si­ty of con­ven­tion­al graphite-based bat­ter­ies, a crit­i­cal advan­tage in avi­a­tion, where bat­tery weight direct­ly con­strains range, pay­load, and eco­nom­ics.

For Mat­ter­net, this part­ner­ship is focused on trans­lat­ing bat­tery per­for­mance into com­mer­cial oper­at­ing advan­tage. Amprius and Mat­ter­net will work togeth­er to opti­mize cell selec­tion, form fac­tor, ther­mal per­for­mance, charge rate, and cycle life for Matternet’s next-gen­er­a­tion air­craft.

The goal is to go beyond cell-lev­el per­for­mance and tune the bat­tery sys­tem around Matternet’s air­craft archi­tec­ture and deliv­ery net­work, improv­ing air­craft avail­abil­i­ty, expand­ing ser­vice areas, and reduc­ing cost per deliv­ery as Mat­ter­net scales com­mer­cial oper­a­tions.

Tom Stepi­en, CEO of Amprius Tech­nolo­gies, added: “At Amprius, we are focused on part­ner­ing with cat­e­go­ry lead­ers in appli­ca­tions where bat­tery per­for­mance changes what is pos­si­ble. Mat­ter­net is exact­ly that kind of part­ner, a com­pa­ny with a proven cer­ti­fied plat­form, real com­mer­cial oper­a­tions, and a clear path to scale.

“By work­ing close­ly with Matternet’s engi­neer­ing team, we can opti­mize our sil­i­con anode tech­nol­o­gy for their air­craft, oper­at­ing mod­els, and cost-per-deliv­ery objec­tives. That kind of align­ment is how bat­tery inno­va­tion trans­lates into real-world com­mer­cial advan­tage.”

With Amprius cells already fly­ing in Matternet’s M2 fleet, the com­pa­nies are now focused on deep­er inte­gra­tion for Matternet’s next-gen­er­a­tion plat­form, with Amprius tar­get­ing vol­ume pro­duc­tion readi­ness aligned with Matternet’s fleet expan­sion plans begin­ning in ear­ly 2027.
