- Testing of 18650-type batteries continues to indicate impressive performance improvement of about 14% versus graphite benchmark batteries at 100 cycles [1].
- Consistent performance: battery with Novacium advanced Silicon anode material matches graphite benchmark battery degradation rates at 100 cycles.
“We are learning a lot from these results at 100 cycles [1], results that continue to surpass our initial theoretical expectations of a 10% improvement in battery performance,” stated Dr.
MAINTAINING BATTERY CAPACITY IMPROVEMENT WITH MINIMAL DEGRADATION AT 100 CYCLES
Analysis of the data in Figure 1, Left below demonstrates that the three industrial-type batteries, which utilize Novacium's custom-engineered silicon material blend, (blue lines), continue to achieve impressive performance at the 100-cycle mark. These batteries exhibit a high discharge capacity of approximately 3.11 Ampere-hours (Ah), surpassing the benchmark set by three comparison batteries (red lines) which have a capacity of about 2.66 Ah. These results mark another significant milestone after 100 cycles of testing. These results, confirm and extend the approximate 14% enhancement in full-battery capacity compared to 100% graphite benchmark batteries, that was observed in the previous 5, 25 and 50 cycles testing.
Figure 1) left shows battery capacity while Figure 1) right shows the capacity change during 100 cycles tests of HPQ and Novacium Gen 1 18650 industrial battery [1].
Furthermore, the data in Figure 1, Right reveals that, at the 100 cycles test mark, the measurable cycle degradation between the batteries made entirely of graphite (the red lines) and those incorporating Novacium's custom-engineered silicon base material blend (the blue lines) are in the same 1% to 2% ranges. Considering Silicon's historic tendency to degrade due to expansion and contraction during cycles, these results at 100 cycles are very promising for the Novacium engineered silicon anodes material.
“The data generated during testing has provided the crucial information needed to develop an enhanced second generation of advanced silicon-based material, that we hope will allow us to deliver even better results,” added
OUR 18650 BATTERY VS OTHER COMMERCIAL 18650 BATTERIES
One way to gauge the impact of Novacium's advanced engineered silicon anode material is by comparing its energy density with that of top-performing 18650 commercial batteries. In Figure 2 below, we present a side-by-side comparison, shedding light on the potential of our silicon anode technology to enhance battery performance.
Figure 2) Energy density of top-performing 18650 commercial batteries versus our
advanced engineered silicon anode material blend.
The data indicates that our benchmark graphite battery performs well, while our blend of 90/10 graphite and advanced engineered silicon anode material ranks among the top six batteries on the list. HPQ and Novacium note that these are initial tests in a product that has not been optimized, suggesting there remains room to improve upon this already impressive battery performance.
“I am profoundly encouraged by the results to date,” expressed Mr.
