University of California, Santa Barbara, reinforced a previous 
international patent application by jointly filing applications in the 
US, Canada and Japan for something called a "multicomponent-approach to 
enhance stability and capacitance in polymer-hybrid supercapacitors." 
The BioSolar energy storage approach solves two core problems of 
conventional lithium-ion battery technology 
<http://cleantechnica.com/2016/02/26/new-energy-storage-solution-could-hit-magic-54-mark/>. 
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./
