Nexeon technology overview
Nexeon is a world leader in engineered silicon materials for battery applications. Nexeon has identified a class of material that the company believes will be one of the “best-in-class” in terms of energy density while maintaining physical anode dimensions for long cycle life.

Nexeon’s lithium ion battery anode technology uses silicon in several forms either to enhance or replace the traditional graphite anode. It can be used with graphite as a silicon graphite composite. The battery technology has the potential to improve the performance of the current Li-ion batteries used in electric vehicles and a wide range of consumer electronics.

Nexeon’s development of silicon materials enables the production of batteries with higher energy density. Nexeon has designed its technology for easy adoption in existing Li-ion battery production lines. Nexeon’s silicon materials can be used in combination with conventional polymer binders and current collectors as part of the standard battery manufacturing process. In this way, Nexeon technology truly offers a ‘drop-in’ approach.

Nexeon is developing two types of silicon material solution:

NSP-1

• Silicon based composite powder designed for use in hybrid or low loading anode electrodes (recommended use up to 10wt.% loading)
• Can be used to enhance existing graphite anode electrode active materials and is designed to provide improved cell capacity
• Typical initial anode capacity 400 – 450mAh/g

NSP-2

• Silicon based material designed for use in high loading anode electrode formulations (up to 80 wt.%)
• Significant increase in anode energy capacity and capacity density
• Mitigates expansion through the use of engineered porosity at the particle level in combination with optimised anode design
