By continued growth of its next-generation lithium-metal cell know-how, Cuberg has achieved a near-doubling of cycle lifetime of its cells alongside enchancment in power and energy. Testing of 5 Ah pouch cells by an unbiased third get together confirmed that cycle life has been prolonged from 370 to 672 cycles with 80% capability retention.
The outcomes present that Cuberg has efficiently developed the highest-performing and longest-lived lithium-metal cell on the planet that has been independently validated in a commercially consultant cell dimension (3+ Ah). For the primary time, a lithium metallic cell now exceeds the cycle lifetime of the most recent power/energy cells developed by main lithium-ion producers when examined in the identical biking situations and with the identical cell capacities.
Cell cycle life is a key efficiency criterion for a battery, impacting a variety of priorities for our prospects. Whereas the power density of lithium metallic cells vastly exceeds that of typical lithium-ion cells, low cycle life has traditionally restricted the enchantment of lithium metallic cells. The most recent outcomes affirm that Cuberg’s lithium metallic know-how can fulfill all key efficiency necessities for essentially the most demanding mobility purposes.

Cuberg is engaged with a number of prospects from the aviation trade who require batteries that obtain excessive power density, energy, and cycle life concurrently. Since Cuberg’s acquisition by Northvolt in March 2021, the corporate has considerably expanded its industrial engagements and has shipped 1000’s of cells to prospects prior to now yr.
Cuberg’s first era of cell know-how was validated by the US Division of Power in 2020 and reached 370 cycles with 80% capability retention with a C/2 charging charge (2-hour cost) in a 5 Ah cell. The most recent outcomes attain 672 cycles with the identical charging charge and 80% capability retention restrict in a 5 Ah cell format. Cuberg is now transitioning its know-how to twenty Ah commercial-format cells for its aviation prospects.
Cuberg’s cell know-how has been designed as a drop-in successor to standard lithium-ion know-how. Importantly, it has been proven that typical lithium-ion cell manufacturing gear—reminiscent of that being established at scale by Northvolt—will probably be able to manufacturing Cuberg’s cells with little adjustment. This contributes to sooner and decrease value of scale-up of the know-how whereas offering future improve alternatives for lithium-ion gigafactories being deployed all over the world.
