LT Business Summary

Long Time Technology Co., Ltd. (LTT), also known as Epoch Energy Carbon, is a specialized manufacturer of lithium-ion battery anode materials, primarily generating revenue through the production and sale of high-performance carbon and graphite products. The company’s primary business segments include natural and artificial graphite, mesophase carbon microspheres (MCMB), and advanced silicon-carbon anodes tailored for the electric vehicle (EV) and energy storage systems (ESS) markets. LTT leverages a vertically integrated production model—spanning raw material processing to final surface treatment—to serve Tier-1 battery cell manufacturers and automotive OEMs. Within the competitive landscape, LTT contends with global leaders such as BTR New Material Group, Ningbo Shanshan, and Shanghai Putailai, as well as domestic rival China Steel Chemical Corporation (CSCC). LTT distinguishes itself as a strategic linchpin in the Foxconn-led MIH Open EV Alliance, positioning itself as a premium, ex-China supply chain alternative for high-capacity battery materials. The leadership team is currently headed by Chairman Lin Zhongzheng, who assumed the role following a strategic board reshuffle in late 2025 to align with the company’s expansion into the global EV ecosystem. The executive management is led by CEO and General Manager Dr. Wayne Yen (Yan Wenqun), a materials science expert who holds a PhD from National Tsing Hua University and previously served as the company’s Vice President of R&D. Dr. Yen’s technical pedigree is central to LTT’s innovation in silicon-carbon anodes and high-density MCMB. The company’s board and investor base are notably anchored by the Foxconn (Hon Hai Precision Industry) Group and Fubon Financial, reflecting its status as a core component of Taiwan’s industrial strategy for electric vehicle battery development. This institutional backing provides LTT with both the capital and the captive market access necessary to scale its proprietary anode technologies across international manufacturing hubs.
