Canadian battery manufacturer HPQ Silicon has started production of the first batch of HPQ ENDURA+ 18650 and 21700 cylindrical battery cells powered by Novacium’s GEN3 silicon-based anode technology, which are scheduled for delivery to HPQ by the end of September 2025.

The HPQ ENDURA+ 18650 (4,000 mAh) and 21700 (6,000 mAh) cells offer increased energy density and a lifespan approaching 1,000 full charge–discharge cycles, which the company says it has validated by independent testing.

This is a key step in the commercialization of HPQ’s batteries, and follows recent developments, including the launch of the HPQ ENDURA+ brand and the signing of strategic agreements to accelerate the commercialization in North America of lithium batteries incorporating GEN3 silicon-based materials.

“We continue to receive inquiries from global potential customers and are engaging in technical discussions with leading industry players,” said Bernard Tourillon, President and CEO of HPQ Silicon. “This confirms the growing interest in our battery technology and HPQ ENDURA+ cells. These interactions have allowed us to refine our specifications to better meet market needs. With production now underway, we anticipate an acceleration of partnership opportunities as soon as we start delivery.”
