ADVANCED ENERGY STORAGE SYSTEMS BASED ON NEXT GENERATION MATERIALS AND SYNTHESIS STRATEGIES
Energy storage is an essential and ubiquitous aspect of our world today. Tremendous, unmet need exists for longer lasting portable electronics, more efficient electric vehicles, and alternative sources of power which drive a seemingly insatiable demand for more efficient and powerful energy storage materials and devices.
Sidhu Laboratories is leading advancements in critical technical areas to overcome the hurdles facing next-gen energy storage solutions. Our technology draws upon our expertise in non-traditional and sophisticated organic materials and revolutionary manufacturing techniques. Production scalability of our technology is integral to our business model and we believe also greatly differentiates us in the marketplace.
Our corporate vision is to lead storage technology innovation through development of a integrated, fully accountable battery solution - not a narrow “materials only” component supplier approach.
IN THE NEWS
After completion of LFP and LNMO solid polymer electrolyte optimization, Sidhu Laboratories is pleased to announce polymer electrolyte stabilization of uncoated NMC-811 at room temperature.
NMC-811 is the ideal candidate for next-generation electric vehicles. By achieving full stability with uncoated NMC-811 with our solid polymer electrolyte technology, we can significantly reduce overall system costs and circumvent the high costs associated with advanced coatings (e.g. ALD, sol-gel) as coatings are now not necessary to prevent NMC degradation. The stability of NMC-811 originates from the polymer electrolyte and not from modifications to the NMC-811 particles themselves.
NMC-811 will undoubtedly play a key role in the electrification of automobiles in this decade, potentially pushing electric vehicles beyond a 400 mile driving range. The high nickel-content is vital to improve overall capacity, thus a 20% increase from NMC-622 pushes the capacity of NMC-811 above 200 mAh/g.
Furthermore, by stabilizing NMC-811 uncoated with solid polymer electrolyte technology, we can firmly mitigate the violent hazards associated with the interactions between the conventional liquid electrolyte and NMC chemistry.
Sidhu Laboratories has achieved full stabilization of lithium nickel manganese oxide (LNMO) with our solid-state polymer electrolyte technology for over 100 cycles at room temperature. The LNMO cathode delivers one of the highest potentials available for the current lithium-ion battery cathode materials, resulting in cells with a nominal voltage of 4.7V compared with 3.7V for other cathode types.
The high voltage plateau of LNMO renders a high theoretical energy density of 690 Wh/kg (for the active material). This, in conjunction with LNMO’s excellent rate capability, makes the cathode an ideal candidate for high power applications (e.g. electric vehicles, consumer electronics).
LNMO stabilization with lithium-metal anodes by Sidhu Laboratories proprietary solid polymer electrolyte technology marks an important paradigm shift to zero cobalt systems and a more sustainable future.
Sidhu Laboratories understands the challenge associated with achieving high active mass loading in conventional solid-state battery systems. Furthermore, we observed that in order to fabricate a high performance solid-state battery, one needs to focus on other components of the battery outside the polymer electrolyte separator layer.
Thus, we have created our state-of-the-art Electrode Polymer Electrolyte (EPE) technology. Our EPE line of polymer electrolytes are capable of eliminating inactive, dead-weight materials such as PVDF-based binders, while promoting sufficiently high ionic conductivity and good electrolyte percolation in the composite cathode host. The higher utilization of total electrode weight as active material translates to batteries with higher energy density and lower cost.
Sidhu Laboratories is pleased to announce it has completed its development of high-voltage stable solid polymer electrolytes (SPEs) for rechargeable lithium-ion batteries. Unlike the conventional liquid electrolyte, Sidhu Labs proprietary solid electrolytes can withstand voltages exceeding 5V, thus permitting materials such as lithium nickel manganese spinel (LNMO). Furthermore, this line of polymer electrolytes exhibit high ionic conductivity at room temperature, exceeding 2 mS/cm in value.
Sidhu Laboratories continues its advancement of the development of high density solid-state lithium-ion batteries and prove the scalability of its technology. Recently, we have achieved and demonstrated our first solid-state, rechargeable lithium-ion pouch cell based on LFP vs. Li-metal. Not only can the pouch cell cycle at high rates (i.e. 1C), the cell can operate without external pressure and operate at room temperature. Thus, we have demonstrated that polymer electrolytes can indeed exhibit high electrochemical performance at room temperature.
Work is on currently ongoing to improve the performance of our pouch cells, move onto higher energy dense cathodes (i.e. LNMO and NMC), and scale to larger size cells.
Sidhu Laboratories continues to make progress in its high-performance solid polymer electrolyte (SPE) development, and prove itself as the industry leader in solid-state battery technology.
We have been able to achieve 200 + cycles at 1C (1 hour charge/discharge) with successful repulsion of lithium-metal dendrite growth in our cells. Furthermore, our capacity data excels that of the standard liquid electrolyte.
We continue on our path to commercialize this technology, and deliver one of the most advanced battery solutions in the market.

Sidhu Labs is pleased to report that our proprietary polymer electrolyte, SiLyte, is stable with LFP-based cathodes.
Lithium iron phosphate (LiFePO4, LFP) is the representative material for olivine structured cathode materials. Its specific capacity (~170 mAh/g) is higher than that of the related lithium cobalt oxide (~140 mAh/g). Because of its low-cost, low-toxicity, long-term stability, and well-defined performance, LFP-based batteries are finding a number of roles in electric vehicles and backup power applications.
Work is currently in progress to improve the specific capacity at higher C-rates at room temperature.

Sidhu Laboratories understands that at high temperatures, current existing lithium-ion batteries pose a serious threat of outgassing, fire, and occasionally, explosion. To address these hazards, we have developed the ultra-safe SiLyte - HT Series solid polymer electrolyte.
While being non-flammable and mechanically robust upto temperatures of 800degC, SiLyte - HT Series electrolytes are also capable of experiencing high ionic conduction (1.0 mS/cm at room temperature). Furthermore, its low synthesis cost makes it an attractive option for high-temperature applications.
