Panasonic Energy to purchase silicon anode materials from Nexeon for EV batteries in the U.S.
25 July 2023, 14:14:02
Panasonic Energy announced the signing of an agreement to purchase silicon anode material for automotive batteries from U.K.-based Nexeon to boost the performance of lithium-ion batteries for electric vehicles (EVs). Nexeon’s silicon anode material will be used for lithium-ion batteries to be manufactured at a new facility in De Soto, Kansas, U.S., from 2025.
In general, achieving a higher energy density of battery cells requires improving the capacity of not only cathodes but also anodes. Silicon materials are considered the key to boosting battery performance because their theoretical capacity is approximately 10 times that of graphite, which is currently commonly used as an anode material. However, there is a hurdle to increasing the percentage of silicon in anodes as problems arise from its expansion characteristics when the cells are charged, resulting in battery capacity fading.
Panasonic Energy has actively developed technologies to harness silicon-based materials and become the first company to succeed in mass production of silicon-doped EV batteries. It will be among the first in the industry to use Nexeon’s new high-capacity silicon capable of containing expansion undercharging to boost battery performance. The company will continue to increase the percentage of silicon with the aim of attaining the target of improving the volumetric energy density by 5% by 2025 and 25% by 2030 as stated in Panasonic Energy’s business strategy.
