Si-dominant Li-ion batt bags safety certs

Article By : Enevate

Enevate’s HD-Energy technology delivers 4x energy density to products and processes now certified to UN 38.3, UL 1642, UL 2054, CTIA/IEEE 1725, IEC 62133,and IEC 61950.

Enevate Corp. has announced that their silicon-dominant battery has received global safety and quality certifications for smartphones and other consumer applications, including UN 38.3, UL 1642, UL 2054, CTIA/IEEE 1725, IEC 62133 and IEC 61950. Both of Enevate's cell and battery pack have been certified.

Enevate’s patented HD-Energy technology is a silicon-composite anode film with more than 70% silicon. The technology delivers more than four times the energy density of conventional Li-ion battery anodes. The resulting products provide charging capabilities up to 4C rates without compromising energy density—charging to 90% in just 15 minutes without damaging the cell, while having an additional 35% to 50% runtime in mobile devices, such as smartphones, the company said.

The HD-Energy technology also offers enhanced low temperature operation and provides an inherent safety advantage with a 40% higher overcharge capability, while being able to avoid lithium plating compared to conventional Li-ion cells, Enevate noted.

"These certifications are the first in the industry for a silicon-dominant Li-ion battery and evidence of our technology leadership and commitment to continuous technology innovation," said Jarvis Tou, Enevate’s executive vice president, marketing & products. "It also demonstrates how readily we took our technology from R&D through product development to global certifications and approaching market-ready status," he added.

UN38.3 is a certification to ensure air transport safety of Li-ion batteries. UL1642 and UL2054 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. Enevate’s silicon-dominant anode production process is also ISO 9001 certified, which is required to support certain battery certifications, such as the 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. "Achieving these global consumer electronics certifications now allows us to set our sights on confidently achieving quality and safety certifications in the EV space," Tou noted.
