Asahi Kasei Boosts Silicon-Rich Battery Energy Density with Novel Pre-Doping Tech
Event summary
- Asahi Kasei developed a lithium pre-doping technology for silicon-rich lithium-ion batteries, reducing initial capacity loss and improving energy density.
- The technology uses lithium carbonate as a low-cost sacrificial lithium source, decomposing it during the first charge to supply lithium.
- Internal tests showed a 10% increase in energy density for an NMC cell with a 90% graphite and 10% SiO anode.
- Asahi Kasei plans to license the technology and aims to conclude at least 10 new license agreements by fiscal 2027.
- The company targets a cumulative profit contribution of ¥10 billion or more from this technology by around 2030.
The big picture
Asahi Kasei’s innovation addresses a critical challenge in silicon-rich lithium-ion batteries: the significant initial capacity loss that limits energy density and increases costs. This development aligns with the growing demand for higher energy density batteries in electric vehicles and humanoid robots, positioning the company as a key player in the battery technology space. The licensing strategy underscores Asahi Kasei’s focus on monetizing its intangible assets through its Technology-value Business Creation initiative.
