Sidhu Laboratories

Myth #1: Solid polymer electrolytes have poor room temperature performance. Reality: Sidhu Laboratories has developed a number of novel polymer electrolytes that exhibit high room temperature ionic conductivity, ranging from 1*10 to 1*10 S/cm while exhibiting excellent mechanical strength. Myth #2: Solid polymer electrolytes are limited to cathodes... with low voltages. Reality: Sidhu Laboratories has successfully developed a number of solid polymer electrolytic membranes capable of having an electrochemical stability window up to 5.5V. In addition, Sidhu Laboratories has demonstrated stability with high-voltage materials, such as LNMO. Myth #3: Solid-state batteries need to be under external pressure for operation. Reality: Unlike oxide or sulfide solid-state electrolytes, our solid polymer electrolytes are capable of exhibiting extremely low electrode-electrolyte interfacial impedances. Because of this, our solid-state batteries are capable of being charged and discharged free-standing and without the need for pressure normalized to the surface of the cell, even at the multi-layer level. Myth #4: Solid polymer electrolytes are not lithium-metal stable. Reality: At Sidhu Laboratories, we have developed a strong understanding between the components of our polymer electrolytes and dendrite formation in lithium-metal based anodes. Through rigorous optimization, Sidhu Laboratories polymer electrolytes are capable of successfully cycling with lithium-metal anodes for hundreds of cycles and at relatively high C-rates. Myth #5: Sidhu Laboratories must be using small quantities of the conventional liquid electrolyte, polyionic liquids, and/or ionic liquids. Reality: Nope, Sidhu Laboratories develops true solid-state batteries, and does not utilize any conventional liquid electrolytes or polyionic/ionic liquids in the cathode, interfaces, or within the polymer electrolyte separator layer. Furthermore, we utilize no nonactive separator materials (e.g. PE, PP, PAN).Read More
