Samsung Will Produce Silicon-Carbon Batteries for EVs
Samsung will start the production of silicon-carbon batteries with a technology that enhances energy density relative to traditional lithium-ion batteries. The first application of this new battery technology will be for electric vehicles instead of any smartphone or other portable device.
Collaboration and Evolution
The technology is in developmental stages within the battery division of Samsung Electronics, called Samsung SDI, which has announced a partnership with Korean automobile manufacturer KG Mobility (previously known as SsangYong). The cooperation is aimed at developing battery modules for electric vehicles. These modules will be built on 46-series cylindrical cells using high-nickel NCA cathodes and an in-house silicon-carbon nanocomposite anode.
Advances Made and Benefits Accrued
Samsung has indicated some prime advantages with the new battery design:
- Minimizes battery swelling.
- Prolongs battery life by several orders.
- Petal-less design allows for lower internal resistance and better electrical conductivity.
- Higher charging power and speed.
- Revamped thermal management and manufacturing processes greatly increase reliability and safety.
Application in Electric Vehicles
These new silicon-carbon batteries will be used in next-generation electric vehicles by KG Mobility.
