It’s often rather interesting to keep an eye on the supply side of the electric car industry.

For example, Toray, a producer of separators for lithium-ion batteries, has announced the following:

Toray Industries will step up production of an essential component of batteries used in green vehicles, investing about 10 billion yen ($82.6 million) to boost output at a mainstay South Korean plant.

The component known as a separator is used in lithium-ion batteries for hybrid and electric vehicles. Accounting for 10-15% of the cost of the batteries, these parts help prevent fire and improve battery performance.

In order to boost production, Toray will “add two production lines to the existing four at the plant in Gumi, Gyeongsangbuk-do Province. That will expand its capacity by 50%.”

Toray is a big player in the separator field, with 21.5% global market share in 2013.

I realize we are still a few years (5-10) before solid state batteries arrive, but this goes to show just how much of an impact they can have on price. Solid State batteries will be able to eliminate the separator entirely as the risk of thermal runaway is not present. There’s a huge (by percentage) costs savings right there, and that is before you consider the fact that packaging will be simpler as they also do not need active cooling. I think the CEO of Sakti3 had it right when she was pointing out that we need to look at batteries for EVs as the entire system level and not just the cell level. There are significant costs that can go away when you don’t need liquid cooling, or perhaps any sort of active cooling at all.

You still need polymer ceramics so it’s not reducing but replacing materials.

Thank you for the information, I had thought the separator was mainly a saftey feature and that it wasn’t required for solid state batteries due to thermal runaway not being an issue. I must have misunderstood the full purpose of the separators.

No surprises. As battery production ramps up, so does production at the component suppliers.

It helps validate the cell manufacturer statements.

Gotta keepum separated… slow day
