General Motors is working withForge Nano , a material science startup , to find new ways to enhance the carrying out and lifetime of galvanic vehicle battery cells .
The automaker ’s investment arm , GM Ventures , on Wednesday injected $ 10 million into Forge Nano , which is develop a tenuous coating the startup enunciate will help improve prophylactic and increase the lifetime of cathode - active materials , reducing overall bombardment costs .
As part of the strategic investment , GM and Forge Nano also signed an agreement that will potentially see the automaker using the inauguration ’s finish , an “ nuclear level deposition technology ” called Atomic Armor .
In a Li - ion battery , the cathode is the side that stores the lithium ions when the stamp battery is charge and loose them when discharge . The other electrode in a battery cellular phone , the anode , takes in the lithium ion when the barrage fire is charge and releases them during use . The most common compounding of cathode materials is lithium , nickel , manganese , and cobalt , but Li iron phosphate ( LFP ) batteries are gain ground with GM and other carmaker like Tesla and Ford .
The partnership and investment come in asGM drops its Ultium barrage brandingand moves aside from a “ single cadre , single chemistry , individual form divisor scheme to more of a multi - cell , multi - supplier , multi - chemistry , multi - form factor strategy for our barrage roadmap , ” Jack Crawley , a GM spokesperson , told TechCrunch .
GM ’s EV sales mature 60 % year - over - year in the third one-fourth , but that growth is n’t reaching the stride the fellowship and investor had hoped for . EVs still make up only 4.9 % of GM ’s totalthird - quarter sales , and CEO Mary Barra fall 2024 guidance to 200,000 eV sell .
GM Ventures always invests in startups with an eye toward potential strategical partnerships to ameliorate its own products . In the electrification and battery blank , GM Ventures has invested $ 167 million in 18 portfolio companies , include startups likeSoelect , Mitra Chem , andSolidEnergy Systems .

“ GM is always looking for means we can make EVs more efficacious [ and ] quest after dear battery carrying into action , ” Crawley say . “ So nuclear layer deposition — the ability to manipulate our chemistry and anatomical structure of our battery stuff at the atom - by - atom point — is sure something we ’re concerned in . ”
Crawley noted that this technology could lead to quicker commit rates , increased Department of Energy density , and longer lived bombardment .
Paul Lichty , Forge Nano ’s CEO , add up that the Atomic Armor political platform increases the safety of cells by helping to prevent things like thermal runway event , which can direct to shelling fervidness .
That ’s because Atomic Armor is made of an ultra - thin ceramic layer to coat material down to the nuclear particle tier , leading to more stable and rich performance , according to Lichty .
assault and battery cell material today are typically invent with coating , but Lichty say those are n’t uniform and they ’re not at the atomic level .
“ We see the downside there when it come to shelling that do n’t have enough energy for things like eVTOLs or galvanic aircraft or farseeing - cooking stove vehicle , ” Lichty said . He also note that most of Forge Nano ’s commercial client today are in the aerospace and defence industries , but this investment from GM is a step toward broad borrowing in the EV industry .
“ We ’re basically preventing erosion in the cell that makes them give way cursorily , whether that ’s from heat or from usage , ” James Trevey , Forge Nano ’s chief engineering officer , told TechCrunch . “ The more uttermost the software , the more improvement you ’ll see from Atomic Armor . ”
Lichty said in trials and commercial deployments , Forge Nano has been capable to “ extract more lithium out of that cathode when we motorbike than anybody else ” using “ atomic number 3 that ’s already in there , ” thus increase the vigor denseness of a battery electric cell by up to 20 % .
“ It ’s kind of tantamount to find 20 % more Li just lying around on the ground and being able to get at that essentially for free , ” he lend .
Forge Nano ’s coating technology can be plugged directly into a cell maker ’s subsist cognitive process to create cost savings at scale of up to 20 % , the CEO say .
The society ’s barrage fire cellular phone subsidiary , Forge Battery , is using the Atomic Armor political program to produce prototype cell today while it retrace its own gigafactory in North Carolina using a $ 100 million honour the companyreceivedin September from theDepartment of Energy . Forge Battery expect to protrude get 2170 cellular telephone with Forge ’s Atomic Armor inside in 2026 .
