The BioSolar energy storage approach solves two core problems of conventional lithium-ion battery technology. One is the cost of materials, and the other is the limited capacity of the cathode compared to the anode. BioSolar has solved the cost and capacity problem by developing an inexpensive polymer for the cathode. "Our novel high capacity cathode is engineered from a polymer, similar to that of low-cost plastics used in the household. Through a smart chemical design, we are able to make the polymer hold an enormous amount of electrons. The estimated raw materials cost of our cathode is similar to that of inexpensive plastics, with a very high possible energy density of 1,000 Wh/kg." BioSolar's research also indicates that the new polymer enables batteries to charge and discharge rapidly while far outlasting the lifecycle of conventional lithium-ion energy storage. According to the company, conventional batteries drop down to 80 percent of their storage capacity after 1,000 charge/discharge cycles. When the new polymer is used in a supercapacitor, BioSolar's lab work has demonstrated a lifespan of 50,000 cycles without degradation.
