Epsilon Advanced Materials (EAM) and Daejoo Electronic Materials (Daejoo), have announced a joint development program to develop a silicon-graphite composite (graphite-rich) by combining Epsilon’s graphite and Daejoo’s silicon material.

The Mumbai-headquartered Epsilon Advanced Materials is a leading global manufacturer of environmentally conscious lithium-ion battery (LiB) anode and cathode materials. While South Korea-based Daejoo is one of the leading global producers of silicon anode materials for lithium-ion battery (LiB).

The partners plan to develop a product that outperforms current material technology used in LiB, delivering enhanced performance and efficiency. The companies state that Japanese trading company Nagase played a role in enabling the partnership.

The partners have set an ambitious target to develop Gen-1 Graphite rich silicon composite anode materials for LiB with capacity of 450 - 600 mAh/g, which they say will improve discharge capacity by 50 percent and lifespan of the battery by thousands of cycles.

As per the understanding, EAM will supply synthetic graphite, which will be used to create and evaluate SiOx-graphite composites in Daejoo’s laboratories. On the other hand, Daejoo will provide samples for the same purpose, allowing EAM to tailor and test SiOx-graphite composites in its own labs.

They aim to qualify the SiOx-graphite composite materials with their customers to develop innovative products. According to EAM’s current schedule, the first stage development and evaluation of the SiOx-Graphite composite material is expected to be completed by end-2024 and then explore the material qualification with cell manufacturers jointly. 

Vikram Handa, MD, Epsilon Group, said, “We are excited to announce our partnership with one of the world's leading producers of silicon anode materials to develop revolutionary battery material technology. This collaboration shows our dedication to accelerating India's and global transition to clean energy and sustainable mobility. Through continuous R&D efforts like these, we are committed to pioneering advancements in battery innovation. Upon successful completion of our rigorous in-house evaluation processes, we will be well-equipped to meet the evolving needs of the mobility industry by providing high-performance, safe battery solutions.”

Dae Woon Park, MD, Daejoo Electronic Materials, said, “This partnership marks a significant step forward in our mission to innovate and enhance battery performance. Collaborating with EAM, not only strengthens our presence in the rapidly growing Indian market but also aligns with our global strategy of developing advanced materials tailored to the diverse needs of customers and the market. With EAM, we aim to develop cutting-edge battery materials that will drive sustainable progress and deliver unparalleled value to our customers and stakeholders.”

It is interesting to note that the silicon-graphite battery materials representing a significant advancement in lithium-ion battery technology. It combines the high capacity of silicon with the stability of graphite, which offers a superior alternative to traditional graphite anodes, meeting the increasing demands for higher performance, longer life, and fast charging in modern battery applications. This makes it well suited for the evolving needs of the automobile industry and other high-power demand sectors.

Chartered Speed has deployed 11 electric buses for staff transportation for DCM Shriram at Jhagadia GIDC, Bharuch. The service was inaugurated by Sanyam Gandhi, Whole-time Director at Chartered Speed and Aditya Shriram, Deputy Managing Director at DCM Shriram.

The deployment is part of an effort to shift employee mobility towards electrification. Chartered Speed operates a fleet of over 2,000 buses across six states, serving 350,000 passengers daily.

The electric buses are equipped with several technologies for fleet management and passenger safety. It comes with real-time GPS tracking and onboard Driver Monitoring Systems (DMS). CCTV cameras, fire protection systems and first-aid kits are installed in every vehicle.

The company currently provides school and staff transportation services to various clients, including GHCL Limited and Apple Global School.

Sanyam Gandhi, Whole-time Director, Chartered Speed, said, “With the recent deployment of electric buses, we are strengthening our commitment to reducing the carbon footprint of our operations and supporting the transition to greener transportation solutions. Our vision is of building a large, clean energy-powered fleet that aligns with global trends towards electrification in public transport. We remain focused on integrating technology in our services not only enhances operational efficiency but also fosters a culture of safety that we believe is essential for the future of transportation.”

Tata Motors, one of the leading passenger vehicle manufacturers in the country, has attained a new milestone in the Indian electric vehicle (EV) market, with cumulative sales of its TATA.ev range exceeding 250,000 units.

Since the launch of the Nexon.ev in 2020, the company has secured a 66 percent market share of all electric passenger vehicles sold in India to date. The Nexon.ev has become the first electric model in the country to surpass 100,000 cumulative sales.

At present, the company’s green vehicle offering includes the Tiago.ev, Punch.ev, Nexon.ev, Curvv.ev and Harrier.ev for personal use, alongside the XPRES-T EV for fleet operations.

To support its EV customers, Tata Motors has established an ecosystem, which includes access to over 200,000 charging points, including home, community and public chargers. A digital platform providing coverage for over 20,000 public chargers. Around 100 mega charging hubs operational across key corridors, offering speeds of more than 120kW. Approximately 1,500 dedicated EV service bays nationwide, staffed by over 5,000 technicians.

The automaker stated that every TATA.ev vehicle is manufactured with more than 50 percent local content. In collaboration with other Tata Group companies, the firm has localised the production of battery packs and battery management systems. The supply chain also includes domestic production of power electronics, wiring harnesses and thermal management systems.

Going forward, Tata Motors has outlined a robust growth strategy through to 2030:

• Upcoming Launches: The Sierra.ev and a new Punch.ev are scheduled for release in CY26, followed by the Avinya luxury range at the end of 2026.
• Portfolio Growth: Five new nameplates are planned by FY2030.
• Infrastructure Targets: The company aims for 400,000 charge points by CY2027 and 1 million by 2030.
• Battery Sourcing: Future models will use battery cells produced at the Agratas gigafactory in Sanand.

Shailesh Chandra, MD & CEO, Tata Motors Passenger Vehicles, said, “Crossing 250,000 EV sales reflects how electric mobility is fast becoming part of everyday Indian life. Our customers are driving more, travelling farther, and increasingly trusting EVs as their only cars. Our EV journey which began in 2018, was never about leading alone but about building the ecosystem to enable India’s transition to clean mobility. This progress is the outcome of the government’s forward-thinking policies, the steadfast support of our supplier partners and charging infrastructure providers and above all, the trust and enthusiasm of TATA.ev customers. As EV adoption accelerates, our commitment remains clear: to mainstream electric mobility by making it accessible across segments, strengthening the ecosystem, and investing in India-first technology and localization. This is how we will continue to lead India’s growing EV market.”

The company also intends to focus on the circular economy by reusing batteries for energy storage and providing battery health checks for second-hand owners.
