InterBattery Seoul Guide: Korea's Battery Show and Leads
By Ilyas Kerbal,

InterBattery is Korea’s largest battery exhibition, and it’s where Korea’s three big cell makers, LG Energy Solution, Samsung SDI and SK On, reveal their next-generation cells alongside materials leaders such as POSCO Future M, EcoPro and L&F. It’s organised by the Korea Battery Industry Association, COEX and KOTRA. For automakers and ESS developers looking for non-Chinese battery supply, and for suppliers to the Korean battery industry, the InterBattery attendee list is a key resource.
This guide is for the March 2027 edition.

Registration and data
Registration and exhibitor search run through the COEX EMS event site. The big three’s booths get crowded, and meetings with their procurement and partnership teams don’t happen by walking up. An enriched list of attendees from automakers, ESS developers and suppliers helps you plan who to approach and when.
Pros and cons
| Pros | Cons |
|---|---|
| The leading non-Chinese battery makers in one place | Smaller than CIBF |
| Cheap or free entry | Fees rise for late registration |
| Central Seoul venue | Mostly Korean-language |
| Strong conference | Big three booths get crowded |
| Good for IRA/EU-compliant supply chain sourcing | Overlaps with other March battery shows |

FAQ
When is InterBattery?
Every March at COEX, Seoul. The 2026 edition ran 11–13 March.
Is InterBattery free?
Yes, during the December–January free registration window. Later registration costs more.
Who exhibits at InterBattery?
LG Energy Solution, Samsung SDI, SK On and materials leaders such as POSCO Future M, EcoPro and L&F.
Can I get the InterBattery attendee list?
There’s no exportable list. I can build an enriched list of exhibitors and attendee profiles.
Need InterBattery leads ready for your CRM?
Event apps are built for browsing, not for sales teams. They cap connections, hide data behind logins and rarely let you export anything. I pull attendee, exhibitor and speaker data from the app and the event website, enrich every profile and hand you a clean file before the doors open, so your reps can book meetings in advance and follow up properly afterwards.
