- Addionics has developed a new low-temperature battery architecture to enhance performance.
- The new architecture replaces traditional planar metal foils with three-dimensional porous current collectors.
- Low temperatures pose a dual challenge for applications like electric vehicles.
- Addionics is applying the technology across various electrified systems.
Low-temperature environments have long been one of the most challenging obstacles for lithium-ion batteries. As temperatures drop, the available energy of the battery decreases, output power diminishes, and charging speed slows down, affecting electric vehicles, heavy-duty trucks, drones, and even spacecraft. Israeli battery technology company Addionics claims to have developed a new architecture that addresses this issue from within the battery's internal structure, officially launching its low-temperature battery architecture based on "Smart 3D Porous Current Collectors." This architecture replaces the traditional planar metal foils in conventional batteries with an engineered three-dimensional porous structure.
Technical Features of the New Architecture
Addionics states that the architecture aims to improve the pathways for lithium ions and electrons within the battery, allowing it to retain more of its original performance even in low temperatures. Traditional lithium-ion batteries typically use planar metal current collectors to guide electron transport between electrodes. Addionics, however, attempts to change this geometric structure. Its three-dimensional porous current collectors enable the electrolyte and lithium ions to penetrate the structure, creating additional transport channels within the electrodes. This effectively shortens the transport distance, increases the accessibility of active materials, and distributes the electrochemical reactions across a larger volume.
Low temperatures impose a dual pressure on electric vehicles. The available energy and power output of the battery decrease simultaneously, but the vehicle requires additional energy for cabin heating, battery heating, and thermal management preparation before charging. Addionics points out that in severe winter conditions, electric vehicles may lose up to about 40% of their range. For applications where electrical supply directly affects operational capability, the problem is even more severe. Heavy-duty electric trucks may face power declines in low temperatures, affecting load capacity or route planning. The mission duration and operational range of military drones are similarly reduced. Spacecraft must rely on heaters and additional thermal control hardware to maintain the battery within an appropriate operating temperature range.
Therefore, the core challenge is not merely increasing energy storage but ensuring that the stored energy can still be effectively utilized under harsh conditions. Dr. Moshiel Biton, CEO and founder of Addionics, stated that the company is eliminating some of the major limitations long faced by electrified systems by changing the internal architecture of the battery cell. This architecture is particularly critical at low temperatures because low temperatures slow down electrochemical processes and make the movement of lithium ions within the battery more difficult.
Wide Applicability of the Technology
While low-temperature electric vehicle performance is the most direct application scenario, Addionics positions the technology as applicable to a wider range of electrified systems. In the electric truck sector, improved low-temperature performance helps maintain power output during long winter hauls. For drones, it can extend mission duration and enhance operational flexibility. In aerospace applications, if less battery heating is required, it will have a cascading effect on the spacecraft's power system, potentially reducing the need for energy storage, solar arrays, thermal control hardware, and even launch mass. Addionics states that the company is collaborating with enterprises in automotive, defense, aerospace, robotics, energy storage, and other industrial sectors to advance the technology.
The announcement is based on the company's own technical claims, and the press release does not provide detailed independent performance data for the new low-temperature architecture. However, the concept reflects an increasingly important direction in battery development: engineers are no longer solely focused on discovering new chemical systems but are also beginning to explore how to enhance overall performance by modifying the physical internal architecture of the battery cell.

The Future Trend of Low-Temperature Battery Technology
The impact of low-temperature environments on battery performance has always been a challenge for electrified systems. Addionics' new three-dimensional porous current collector architecture aims to improve lithium-ion transport at low temperatures, thereby enhancing the range and charging performance of electric vehicles and other applications. This technology is not only targeted at electric vehicles but can also be extended to areas such as military drones and spacecraft, demonstrating its potential for wide application. As the demand for electrification grows, such innovative technologies will become an important direction for future battery development.
