- Testing continues to indicate remarkable performance improvement, after 50 cycles, surpassing the capabilities of traditional graphite benchmark batteries by approximately 14% [1].
- Minimal and consistent performance degradation of only about 1%, compared to benchmark graphite batteries range of 1% to 2%.
- Outperforming similar commercial batteries, showing degradation rates of near 1% for Novacium batteries compared to near 5% for Samsung INR18650-35E Battery [2].
“These ongoing results continue to surpass our expectations [1],” stated Dr.
MAINTAINING 14% BATTERY CAPACITY IMPROVEMENT WITH MINIMAL DEGRADATION FOR 50 CYCLES
The graph displayed below (Figure 1, Left) show the battery capacity outcomes and (Figure 1, Right) the changes in capacity during the 50-cycle testing of the 18650 batteries. The blue lines depicting the results of the 18650 batteries comprised of 90% wt graphite and 10% wt Novacium's custom-engineered silicon material blend, a material for which HPQ holds exclusive global licenses, while the red lines depict the results for the batteries made entirely of graphite.
Figure 1) Capacity (left) and Capacity change (right) during 50 cycles tests
of HPQ and Novacium Gen 1 18650 industrial battery [1].
Analysis of the data in Figure 1, Left reveals that the three industrial-type batteries, which utilize Novacium's custom-engineered silicon base material blend (blue lines), continue to demonstrate impressive performance at the 50-cycle mark. These batteries exhibit a high discharge capacity of approximately 3.18 Ampere-hours (Ah), surpassing the benchmark set by three comparison batteries (red lines) with a capacity of 2.70 Ah. These results mark another significant milestone after 50 cycles of testing. These results, confirm and extend the 14% enhancement in full-battery capacity compared to 100% graphite benchmark batteries, that was observed in the previous 5 and 25 cycles testing.
Furthermore, the data in Figure 1, Right reveals that, at the 50 cycles test mark, the measurable cycle degradation between the batteries made entirely of graphite (the red lines) ranges from 1% to 2% and those incorporating Novacium's custom-engineered silicon base material blend (the blue lines) is consistently around 1%.
“These are encouraging indicators of the material's commercial viability in the battery manufacturing sector,” added
COMPARING CAPACITY DEGRADATION BETWEEN 18650 BATTERY TYPES
One of the best to ways to visualize the potencies of our degradation results to date is to compare side by side industry 18650 type graphite batteries capacity degradation with the Novacium 18650 batteries at the 50 cycles benchmark.
The graph displayed below (Figure 2, Left) showcases change in capacity results for a Samsung INR18650-35E Battery, and (Figure 2, Right) the changes in capacity during the 50-cycle testing of the 18650 batteries made using Novacium's custom-engineered silicon material blend.
Figure 2) On the right we have the capacity change data for a Samsung INR18650-35E Battery [2] and on the
right the change in capacity of HPQ and Novacium Gen 1 18650 industrial battery [1].
The data clearly demonstrates the potential of our material. At the 50 cycles test mark, the Samsung INR18650-35E Battery capacity loss was around 5%, while the HPQ and Novacium Gen 1 18650 industrial battery loss was near 1%.
“I am profoundly encouraged by these promising results,” expressed Mr.
