At ACE, we are developing a continuous stream of improvements in battery technology that make a meaningful difference for the design, performance, and broad adoption of EVs. Our team is working hard to develop new materials, chemistries and cell formats that align with the needs of electric vehicle manufacturers.
We are in the final stages of completing the development of our proprietary Advanced LFP chemistry and our 1-meter Very Large Format (VLF) cell. Both of these innovations can provide immediate solutions to automotive OEMs who are looking to improve the performance and safety in their electric vehicles. Moving forward, our innovations will provide safe technologies with even higher energy density, faster charging and other attributes that will lead to even better performing electric vehicles.
SUPERIOR BATTERY CHEMISTRY
ACE has engineered a new LFP-based chemistry that results in significantly higher energy density while maintaining the highest safety standards. With an energy density of 190-200 Wh/kg in a safe, low-cost chemistry, Advanced LFP is an excellent alternative to NMC and NCA in many automotive applications.
HIGHER ENERGY DENSITY
190-200 Wh/kg, delivering up to 25% higher energy density than existing LFP cells on the market.
LONG CYCLE LIFE
5,500 charge-discharge cycles, ensuring the battery outlasts the life of the vehicle.
Safe materials that significantly reduce the possibility of battery fires or explosions.
Significantly lower cost versus NMC and NCA chemistries that contain nickel and cobalt.
Engineered to be fully recyclable, so valuable materials can be recovered instead of entering the waste stream.
The materials used in ACE cell chemistries are readily compatible with standard cell manufacturing equipment regardless of cell format: cylindrical, prismatic & pouch.
Very Large Format (VLF) Cell
In "Project Magnus," ACE is developing a 1-meter very large format (VLF) cell-to-pack prismatic cell which will enable additional vehicle range while reducing costs. The first key milestone in Project Magnus was in May 2022 when ACE filed a patent for the cell's unique design.
INNOVATIVE CELL FORMATS
The VLF cell is optimized for electric vehicle applications in two important ways:
The highly efficient architecture of the VLF cell will boost the energy density from about 200 Wh/kg found in a cylindrical cell using Advanced LFP to 250 Wh/kg. This is about the same as the energy density of NMC/NCA, but in a much safer, more cost-effective cell.
Maximizes energy density for significantly greater vehicle range
Simplifies the battery system to lower costs and provide design flexibility
ACE's VLF cell will reduce the size, weight, and complexity of an EV's battery system, lowering cost and providing more design flexibility. Today's EV's contain thousands of small cells assembled into modules, which are then housed in a battery pack. ACE VLF cells will be integrated directly within the pack, eliminating the need for module components. The VLF cell design can be customized to meet the requirements of any EV, and will be available for licensing in early 2023.
DRIVING BETTER PERFORMANCE
Compared to NMC or NCA, LFP chemistry offers significant cost and safety advantages for electric vehicles. While historically NMC/NCA batteries have had higher energy density, ACE has addressed this issue by optimizing both LFP chemistry and cell format.
ACE’s new Advanced LFP chemistry alone offers up to a 25% increase in energy density over existing LFP chemistries on the market today. When Advanced LFP is used in our highly efficient VLF cell, energy density increases by another 25%. At 250 Wh/kg, Advanced LFP in a VLF cell provides about the same energy density as the NMC or NCA batteries being used in many electric vehicles today – but with a much better safety profile and significantly lower costs.
ACE offers licensing packages for our entire technology portfolio, which includes our future innovations. All of our technology transfer programs cater to the specific needs of our customers and leverage the skills of our highly competent team.
ACE advanced battery cell chemistries and formats are optimal for electric vehicles and are also applicable to grid storage applications. Our unrelenting commitment to safety as a cornerstone of our innovation is always our focus regardless of the application.
