Overview

Dragonfly Energy announced the receipt of a U.S. Patent and Trademark Office notice of allowance for ‘Powderized Solid-State Electrolyte and Electroactive Materials,’ enhancing protection for its solid-state battery manufacturing processes. This follows similar patent approvals from the European Patent Office on June 15, 2026, and the Japan Patent Office on April 23, 2026. The company is advancing cycle testing of coin cells using its dry electrode manufacturing process, although prototype pouch cell production is deferred until at least early 2027.

In Depth

Key Findings

Dragonfly Energy has received a notice of allowance from the U.S. Patent and Trademark Office for its patent application titled ‘Powderized Solid-State Electrolyte and Electroactive Materials,’ significantly strengthening its intellectual property protection for critical solid-state battery manufacturing processes. This U.S. patent grant follows previous approvals from the European Patent Office on June 15, 2026, for ‘Systems and Methods for Dry Powder Coating Layers of an Electrochemical Cell,’ and from the Japan Patent Office on April 23, 2026, for an application with a similar title to the U.S. patent.

Technical/Clinical Details

These patents safeguard Dragonfly Energy’s dry electrode process, a technology deemed crucial for enhancing the performance and cost-efficiency of all-solid-state batteries. The dry electrode manufacturing method eliminates the need for liquid solvents in electrode formation, potentially leading to reduced environmental impact, simplified manufacturing, and lower production costs. Dragonfly Energy is currently utilizing this dry electrode process to produce electrode reels and is conducting cycle testing on solid-state battery coin cells. However, the production of larger prototype pouch cells has been deferred until at least early 2027, as stated in the company’s 2025 annual report.

Background & Context

A significant challenge in the mass commercialization of all-solid-state batteries is establishing an efficient and cost-competitive manufacturing technology. Traditional wet processes involve the use of toxic solvents and require substantial energy for drying, increasing manufacturing costs and environmental burden. The dry electrode process is gaining considerable attention across the battery industry as a promising approach to overcome these limitations. Dragonfly Energy’s successive patent approvals in key markets—the U.S., Japan, and Europe—suggest that its technology could hold a competitive advantage globally, potentially opening avenues for future licensing and strategic partnerships.

Strategic Significance & Outlook

The reinforcement of its patent portfolio in major markets is a critical strategy for Dragonfly Energy to establish a strong presence in the solid-state battery market. The dry electrode technology is expected to accelerate the mass production of solid-state batteries, ultimately contributing to cost reduction and performance improvements in applications such as electric vehicles (EVs) and energy storage systems. While the delay in prototype pouch cell production might be a temporary setback, the ongoing progress in coin cell cycle testing indicates steady technological advancement. The industry will closely watch Dragonfly Energy’s future technological developments and its roadmap towards mass production.
