Recently, the 6th International Forum on Advanced Battery Electrolyte/Separator Materials Technology (ABES 2023) was successfully held in Suzhou. Rolechem attended the forum and shared its latest development progress in electrolyte additives for lithium-ion batteries.

One of the sessions at this international forum primarily focused on the latest progress in technology and applications of electrolyte additives for lithium iron phosphate ($LFP$) and sodium-ion batteries. Faced with the growing demand for high-performance batteries, the exploration and development of different technological pathways in battery materials have expanded the industry's understanding of how various improvement approaches impact overall battery performance. During this technical conference, multiple enterprises, including Capchem, presented reports on utilizing the development of various novel additives and additive formulations to drive improvements in different battery performance indicators. Among them, Dr. Yingtao Chen from Rolechem delivered a report sharing the effects of novel silicon-based compounds on battery cell performance. The development and exploration of additive applications have gradually become one of the mainstream approaches for enhancing comprehensive battery performance.

Dr. Yingtao Chen highlighted the impacts of four novel silicon-based compounds on cell performance. The novel additives ARC-Si03, ARC-Si04, ARC-Si05, and ARC-Si06 demonstrated a significant inhibitory effect on the growth of moisture and acidity within the electrolyte. Furthermore, after introducing these silanes, the rate performance of the cells was optimized, low-temperature characteristics were improved, and high-temperature storage was enhanced. Concurrently, no significant degradation in cycle life was observed, yielding highly ideal performance improvement indicators. Among the four additives, ARC-Si05 exhibited the best inhibitory effect on moisture and acidity. The ranking for moisture inhibition efficiency was ARC-Si05 > ARC-Si06 > ARC-Si03 > ARC-Si04, while the ranking for acidity inhibition efficiency was ARC-Si05 > ARC-Si04 > ARC-Si03 > ARC-Si06.

During the research process of different novel additives, Dr. Yingtao Chen proposed several insights regarding the structure-activity relationship (SAR) of electrolyte additives. He emphasized that systematic research approaches must be highly valued because the impacts of different types and ratios of additives on battery cells are complex and comprehensive.

In addition to the novel silicon-based additives, Dr. Chen also shared findings on the impact of DTD derivatives (Spiro-DTD & Bi-DTD) on cell performance. The stability of the bi- and spiro-DTD structures is significantly enhanced compared to traditional DTD, while the battery cells demonstrated outstanding performance.

At the report venue, Dr. Chen also introduced Rolechem's main products and the progress of its sodium-ion battery additives to the audience, and answered questions regarding the company's new product development.

With the accelerated progress of the new energy industry, the comprehensive enhancement of battery performance has become an inevitable trend. The continuously growing global demand for high-specific-energy batteries, coupled with the deepening collaboration between domestic production and research, has provided a fertile soil for the development of battery materials. Adhering to "independent R&D and innovation-driven growth" remains Rolechem's long-term development strategy. Looking ahead, Rolechem will continue to deeply cultivate battery materials, accelerate its collaborative layout in the new energy field, and empower the long-term development of green causes.
