In the battery space, Anteo has utilised its word-class capabilities in surface-chemistry to develop proprietary silicon composites, an active material component that allows for the creation of higher energy density anodes and lithium ion batteries.
The need for higher energy density batteries
Rapidly advancing applications such as consumer electronics, electric vehicles and energy storage systems rely on lithium ion batteries (LIB) with progressively higher energy density to satisfy the need for longer runtimes, smaller and lighter products, and lower cost. Graphite is the conventional anode active material but it has reached its limits. New higher capacity active materials are required to drive further improvements in the energy density of lithium ion batteries.
Anteo’s proprietary silicon composite materials
By mitigating key processing and performance challenges associated with the use of silicon, Anteo’s silicon composites focus on pushing the amount of silicon that can be integrated into battery anodes to the next level. Anteo’s near term focus is on increasing the anode’s silicon content to up-to 20%, thereby greatly increasing the storage capacity of today’s lithium ion batteries. This approach will help deliver:
- Longer runtimes per charge for electric vehicles, mobile electronics and energy storage systems.
- Smaller batteries and lighter batteries for advanced mobile electronics, electric vehicles and drones.
Process and scale-up
Anteo’s processes were established with commercialisation in mind and so the silicon composites use proven industry processes for production and are based on commercially available raw materials.
Unlike many other approaches that require expensive chemical vapour deposition techniques, Anteo’s silicon composites are fabricated by using easy to handle water-based processes that can be easily scaled to larger volumes of production. For our customers and partners, this silicon composite approach means that:
- Processes are consistent with the industry move towards water based processing of anodes
- Improved processing and integration of silicon with conventional graphite anodes
- Silicon composites that slot right into the battery manufacturing processes currently in use.
