Event overview
CLE 2027 returns to the Nanjing International Exhibition Center from 21–23 April, bringing lithium-battery cells, energy-storage systems and new-energy manufacturing equipment under one roof. The 24th edition of the Jinlang series builds on a 2026 show that reported 950+ exhibitors and 60,000+ visits across 65,000 sqm.
Buyers from battery makers, storage integrators, electric-vehicle and two-wheeler producers, and equipment importers use the floor to compare cells, materials, BMS and production lines. Three days, a professional B2B audience and Nanjing's position in Jiangsu's battery belt make this a working sourcing trip rather than a consumer expo.
TL;DR
Visit to shortlist Chinese cell, material, BMS and equipment suppliers in three days, with enough breadth to compare offers side by side. The Nanjing location also allows factory visits across Jiangsu before or after the show.
Exhibit to reach Jiangsu battery manufacturers, storage integrators and regional distributors who specify components and production equipment. A 9 sqm standard booth keeps entry cost low for a first China show.

Impact
CLE matters because it lands at the front of the spring battery-sourcing calendar in Jiangsu, the province that produces a large share of China's power batteries. For a buyer, the value is supplier density: cells, materials, BMS, storage cabinets and production equipment in one venue, with factory visits possible in the same trip. For a seller, it is a lower-cost route to regional integrators and distributors than a Shenzhen flagship booth.
Audience quality
The audience is professional and engineering-led: cell and pack makers, storage integrators, equipment buyers and distributors. The organiser claims 9,000+ overseas buyers and 1,800+ buying delegations, which suggests a meaningful export component, though the figures are promotional. Expect Mandarin-first conversations and technical staff on most stands; bring a Chinese-speaking colleague or a translation app for specification talks.
Exhibitor outcomes
A 9 sqm standard booth at CNY 6,000 keeps the fixed cost low. ROI depends on pre-booked meetings: with 950+ exhibitors and 60,000+ visits, walk-by traffic is broad but not automatically qualified. Exhibitors selling cells or materials should target pack makers and integrators; equipment suppliers should book demonstrations and follow up with factory visits. No audited ROI or rebooking rate is published, so model the show on meetings booked, not on headline visitor counts.
Intelligence
Key market insights, trends, news and related events to help you understand the bigger picture.
Why it matters
Jiangsu is China's largest power-battery production base, with a dense supplier cluster around Nanjing, Changzhou and Wuxi. CLE gives international buyers a regional entry point rather than a national flagship, which shortens supplier discovery and makes factory visits practical.
Key trends shaping this market and its wider industry.
Storage moves from demo to bankable projects
Grid-scale and commercial storage procurement is shifting toward bankable systems with warranties, thermal management and grid-code compliance, not just cell price.
What it changes: Buyers now qualify integrators on safety records and service coverage, so exhibitors need project references, not only cell specifications.
Next-generation chemistries enter commercial lines
Sodium-ion, semi-solid and solid-state cells are moving from lab samples to pilot production, while LFP remains the volume workhorse for storage.
What it changes: The show is a place to compare which next-generation suppliers have real production equipment and repeatable quality, not just announcements.
Equipment localisation and export compliance
Chinese battery-equipment makers are localising critical sub-systems while export buyers add carbon-footprint, traceability and customs documentation to their sourcing criteria.
What it changes: Equipment and material suppliers that can document provenance and compliance shorten the buyer's qualification cycle.
CLE sits in a crowded spring circuit. CIBF in Shenzhen is the national flagship a few weeks later, while Jinlang's Zhengzhou and Xuzhou editions cover the same supplier base in other months.
