Si-Dominant Li-Ion Battery Gets Global Safety Certifications
Enevate Corporation has developed the world's first silicon-dominant Li-ion battery which has achieved key global safety and quality certifications—including UN 38.3, UL 1642, UL 2054, CTIA/IEEE 1725, IEC 62133, and IEC 61950—for smartphone and other consumer applications. Both its cell and battery pack have been certified and demonstrate safety and commercial readiness of Enevate's HD-Energy® technology.
Enevateâ€™s patented HD-Energy technologyâ€”a silicon-composite anode film with more than 70 percent siliconâ€”delivers more than four times the energy density of conventional Li-ion battery anodes. The resulting products provide ultrafast, industry-leading charging capabilities up to 4C rates without compromising energy densityâ€”charging to 90 percent in just 15 minutes without damaging the cell while having an additional 35 percent to 50 percent runtime in mobile devices such as smartphones.
The HD-Energy technology offers excellent low temperature operation and provides an inherent safety advantage with a 40 percent higher overcharge capability while being able to avoid lithium plating compared to conventional Li-ion cells.
â€œThese certifications are the first in the industry for a silicon-dominant Li-ion battery and are evidence of our technology leadership and commitment to continuous technology innovation,â€ said Jarvis Tou, Enevateâ€™s executive vice president, marketing & products. â€œIt also demonstrates how readily we took our technology from R&D through product development to global certifications and approaching market-ready status.â€
For example, UN 38.3 is a certification to ensure air transport safety of Li-ion batteries. UL 1642 and UL 2054 are standards intended to reduce risk of a safety event when Li-ion batteries are used in a product. CTIA/IEEE 1725 is a safety and quality certification of rechargeable batteries for use in cellular or mobile phones in the United States.
Similarly, IEC 62133 is a global safety standard for rechargeable batteries in portable devices. Enevateâ€™s state-of-the-art silicon-dominant anode production process is also ISO 9001 certified, which is required to support certain battery certifications such as CTIA/IEEE 1725.
The same HD-Energy technology used in smartphones is being further developed for licensing and use in the electric vehicle (EV) industry. â€œAchieving these global consumer electronics certifications now allows us to set our sights on confidently achieving quality and safety certifications in the EV space,â€ stated Tou.
