Altech Batteries Re-Designs CERENERGY Pack to Enable Increased 90KWh Capacity
Altech Batteries (ASX: ATC) has moved closer to the delivery of a next-generation, high-performance solution for the global energy storage market with an enhanced design of its CERENERGY sodium-chloride solid-state battery pack.
The company’s latest research and development work has shown it could re-design the pack as a higher-capacity battery system.
The re-design focuses on an expanded module concept that delivers greater energy within the same casing and reduces inactive or unheated areas within the battery.
Beehive Cell Arrangement
By shifting from the current 48-cell configuration to a beehive arrangement of 72 cells per module, each pack can achieve an energy capacity of 90 kilowatts per hour — an increase from the original 60KWh — while maintaining the same battery casing structure.
Thermal modelling confirmed effective heat management, showing no excessive build-up during charging and discharging, along with more stable performance under load.
The improvements will deliver higher energy and power density, enhanced thermal performance, and cost reductions of approximately 30% at module and pack levels.
Engineering Design Challenges
Altech believes the new module concept could potentially resolve practical engineering design challenges with simplified cell contacting adding internal space and a cleaner layout.
Further refinements include optimised welding techniques, repositioned temperature sensors, and a new-look frame—collectively enhancing assembly efficiency, structural robustness, and long-term reliability.
These advancements deliver higher energy and power density, resulting in more competitive dollars per kWh and strengthening scalability towards full industrial production.
Higher Capacity System
Altech managing director Iggy Tan said that achieving a higher capacity system with no modifications to the established factory design and setup was a milestone result.
“We are very encouraged by the outcome of our latest CERENERGY program—being able to achieve a 72-cell beehive module design that lifts pack capacity to 90kWh without any change to the existing casing or factory setup is a significant development,” he said.
“This innovation promises to increase energy density and simplify engineering while enhancing thermal management and reducing costs; it strengthens the commercial competitiveness of CERENERGY and confirms its scalability towards full industrial production.”
Additional modelling will continue alongside Altech’s ongoing research to achieve seamless integration into a grid-scale battery pack and ensure optimised performance, reliability, and cost-efficiency for commercial deployment, with the results to inform CERENERGY’s final design.
