Forge Nano’s Atomic Armor coating has shown longer cycle life in specific battery-cell tests, but that does not establish that an electric vehicle’s whole battery pack will last longer in everyday use. The coating is applied to battery materials during manufacturing—not added to a car already on the road—and the sources available do not identify a production EV using it.
What Atomic Armor is and how it is intended to work
Forge Nano describes Atomic Armor as an atomic layer deposition (ALD) process that applies ultra-thin coatings to battery active materials, including cathode and anode powders. It is a manufacturing-level treatment, not a liquid additive or consumer retrofit. Forge Nano’s battery overview describes the coating as a way to stabilize interfaces between active materials and electrolyte.

Those interfaces can be sites of unwanted chemical reactions. Forge Nano says its coatings are intended to limit electrolyte reactions, high-voltage side reactions, gas generation, transition-metal dissolution and mechanical damage as particles expand and contract. Reducing such processes could help slow capacity loss and resistance growth. A U.S. Small Business Innovation Research award description similarly says nanometer-thick coatings may improve wetting, suppress side reactions and mitigate resistance rise during extended cycling. The SBIR award description is a research-program account of the approach, not proof of longer life in a vehicle.

What the published cycle-life examples show
Battery cycle-life results are specific to a chemistry, cell design, test protocol and chosen endpoint. Forge Nano’s archived examples illustrate potential gains, but they are company-reported comparisons rather than a guarantee for other cells. The archived ALD for Batteries page gives these conditions and results:
#1 Best Overall
- EV Battery Analysis OBD2 Scanner
- EVOA OBD2 Scanner for EV Battery Health and Efficiency Insights
| Example configuration | Reported comparison | Test details |
|---|---|---|
| NMC/graphite full cell | 900 cycles uncoated versus 1,450 cycles with Atomic Armor | 3–4.2 V; 0.5C/1C cycling |
| NMC811/graphite | 80% versus 85% capacity retention after 1,000 cycles | 4C/1C cycling |
| Si-C/NMC811 | 290 versus 540 cycles | 4.4 V cycling |
The figures are examples reported by Forge Nano; the archived page does not establish independent replication or provide enough detail here to treat them as directly comparable to a vehicle’s battery warranty or expected service life.
A separate DOE-reported cell result
A U.S. Department of Energy highlight published in 2017 described third-party data showing a 40% lifetime increase for a particular 2 Ah NMC811/graphite cell example. The DOE report concerns that cell configuration; it does not report a 40% extension to a complete EV battery pack.

Compatible with Flooded, AGM, GEL, and EFB batteries. Not for lithium batteries, non-12V batteries (6V/8V/24V), or motorcycles below 30Ah. For 6V testing, choose BA101 Plus. For 24V testing, choose BA101 PRO
Why cell cycle life does not settle EV battery life
A cell’s cycle test is not the same measurement as how long a vehicle pack remains useful. A car battery contains many cells assembled into modules and a pack, with controls and thermal management that affect operation. The cited examples do not establish real-world calendar life, vehicle range retention, pack-level reliability or performance across different climates and driving patterns.

Also look for trade-offs in energy density, charging rate, heat and safety, independent replication, and validation in a production pack or vehicle. A higher cycle count under one protocol cannot answer all of those questions.

Is Atomic Armor in EVs or available to consumers?
The official materials reviewed do not identify a passenger EV model using Atomic Armor-coated cells or a consumer product for applying it to an existing battery. Forge Nano describes battery-material coatings and manufacturing capabilities, and says it is developing U.S.-made cells, including a cell for U.S. Department of Defense testing. Forge Nano’s homepage provides that company context, but does not establish a consumer retrofit or specific EV deployment.
On May 28, 2026, Forge Nano and Group14 announced a collaboration combining Group14’s SCC55 silicon-carbon material with Atomic Armor-coated material and U.S. cell-manufacturing infrastructure. The companies named defense, aerospace and energy storage as target markets. Their announcement is evidence of a commercialization effort, not a named consumer-EV application.

How to read Forge Nano’s performance claims
Forge Nano CTO James Trevey has described the company’s high-energy cells as exceptionally durable and said particle-level Atomic Armor addresses instability in high-nickel chemistries. That is the company executive’s characterization, not independent comparative validation. The most useful distinction for readers is between a promising cell-level result under stated conditions and proof that a production EV pack will retain capacity longer.
