Nanovace called the development “a significant milestone” in its R&D efforts, adding that the patent strengthens its intellectual property portfolio in the energy storage domain. “This breakthrough validates our technological innovation and opens up new opportunities for strategic partnerships, licensing, and potential commercialization in global markets,” the company said.

Nanovace said that it has successfully demonstrated the technology at the lab scale and is now building a pilot plant, expected to be ready by the third quarter of fiscal year 2025-26 (Q3 FY26), to test industrial-scale production. The company said that the development aligns with its goal to lead in sustainable energy solutions and would positively impact its long-term growth.

PCBL Chemical Signs Technology Transfer Deal With Ningxia Jinhua

Earlier this year, PCBL Chemical signed a technology transfer agreement with China-based Ningxia Jinhua Chemical to manufacture acetylene black in India. Acetylene black is a high-end conductive material used in high-voltage power cables, lithium-ion batteries, EV charging systems, semiconductor packaging, and conductive plastics, paints, and coatings. PCBL plans to establish its first acetylene black plant in India to cater to the growing domestic battery market and serve global demand for conductive materials. The initiative aims to enhance supply chain resilience for critical materials.

The company has broadened its specialty chemicals portfolio in recent years, launching over 50 grades under its Bleumina brand for engineered plastics, Nutone for inks, paints, and coatings, and Energia for applications such as conductive polymers, ESD protection, wires and cables, and batteries. The addition of acetylene black is expected to bolster PCBL’s capabilities in the fast-growing conductive segment. The firm recently launched a joint venture, Nanovace Technologies, to develop nano-silicon products for use in lithium-ion battery anodes. A pilot facility at PCBL’s Palej site is expected to be operational in the coming months.

The acetylene black initiative aligns with PCBL’s strategy to tap into global megatrends such as energy transition, grid upgrades, electric mobility, and semiconductor expansion. The global acetylene black market, estimated at 60,000 metric tons, is projected to grow at 19–20% annually to reach 150,000 metric tons by 2030.
