Recently, a wholly-owned subsidiary of S.C, Shenzhen Jiejia Xinchuang Technology Co., Ltd (hereinafter referred to as: Jiejia Xinchuang), successfully delivered the One-Step Composite Current Collector Vacuum Roll-To-Roll Coating Equipment to a key customer. This perfect delivery marks another leap in S.C's R&D capability in the study of vacuum equipment.

Developed by Jiejia Xinchuang to target the large-scale production of composite current collector, the delivered equipment is a type of roll-to-roll vacuum equipment that performs vapor deposition of metal film layers on both sides in one step. The equipment integrates multiple designs such as in-situ tension monitoring and automatic tension control system, self-developed quadruple-feed evaporation source, film cooling drum designed with an innovative structure, and real-time inline monitoring and film testing system, etc., which significantly improves uniformity, deposition rate and reliability of film layers.

The composite aluminum foil film layer fabricated by the roll-to-roll vacuum vapor deposition equipment has a uniformity of 5% and a sheet resistance of 35mΩ, and the equipment is capable of producing at a high linear speed of 20m/min - 30m/min, far exceeding the current market level. Backed by the footprint and technology platform of Jiejia Xinchuang in flexible thin film, the successful delivery of the equipment represented a breakthrough of Jiejia Xinchuang in specialty vacuum equipment for lithium-ion battery, and shows the excellent R&D capability in vacuum coating equipment, while also discovering a broader market space in the future.

A flower bud is about to bloom. In the future, Jiejia Xinchuang will continue to expand R&D investment, renew and upgrade the equipment, and be committed to creating composite current collector production equipment of high yield, high efficiency and sophistication for the new energy market, for the purpose of promoting cost reduction and efficiency improvement of composite aluminum foil and driving the high-quality and high-level development of the composite current collector industry.
