(Yicai) Nov. 27 -- Shares of Guangdong Enpack Packaging surged by their daily trading limit after the Chinese pop can maker said its subsidiary had received a big order from a South Korean manufacturer of lithium-ion batteries, materials, and equipment.

Enpack Packaging [SHE: 002846] soared 10 percent to CNY9.89 (USD1.36) a share as of 2.20 p.m. in Shenzhen today.

The unit inked a deal for its plant in China's eastern Jiangsu province to be the sole supplier of composite battery current collectors for U&S Energy, based in South Chungcheong province, Enpack Packaging announced late yesterday, without disclosing any financial data.

Lithium-ion batteries' current collectors mainly use copper and aluminum foil, while composite current collectors are made up of metal foil and polymer film materials. Compared with metal foil current collectors, composite current collectors can notably enhance lithium-ion batteries' safety and energy density, reducing battery eights and production costs.

The unit will customize and produce 2 million square meters of composite aluminum foil and 1 million sqm of composite copper foil for U&S Energy next year, with the amount of foil bought expected to gradually increase between 2026 and 2029, according to the agreement.

Enpack Packaging only entered the lithium-ion batteries' composite current collector business recently, with related revenue reaching CNY178,000 (USD24,500) last year, accounting for just 0.01 percent of its total, according to its annual earnings report.

The Jiangsu plant, which has an annual production capacity of 100 million sqm of composite aluminum foil and 500 million sqm of composite copper foil, is still in construction, with only some of its production lines in operation, according to Enpack Packaging.
