BioSolar is developing a breakthrough technology to double the storage capacity, lower the cost and extend the life of lithium-ion batteries.
Inspired by nature, we are developing a novel cathode based on inexpensive conductive polymers and organic materials that can fully utilize the storage capacity of conventional anodes. By integrating our high capacity, high power and low-cost cathode with conventional anodes, battery manufacturers can create a super lithium-ion battery that can double the range of a Tesla, power an iPhone for 2 days straight, or store daytime solar energy for nighttime use.
Founded with the vision of developing breakthrough energy technologies, BioSolar’s previous successes include the world’s first UL approved bio-based backsheet for use in solar panels.

Based on our patent-pending supercapacitor technology that uses a novel conductive polymer material, we are developing a high capacity Super Cathode for use by battery manufacturers to create the ultimate high capacity, low cost lithium-ion battery.
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. Instead of conventional cathodes that use lithium-ion intercalation chemistry, which is inherently slow, we exploit the fast redox-reaction properties of our polymer to enable rapid charge and discharge.
Most lithium-ion batteries cannot retain more than 80% of its storage capacity after 1,000 charge-discharge cycles. The stable redox chemistry of our cathode material can enable much longer life. Our laboratory experiments have shown that our cathode can easily cycle over 50,000 times without degradation in supercapacitors, and we believe that it can be very effective in batteries as well.
By enabling higher charge-discharge cycles, we can extend the life of lithium-ion batteries and further reduce the total cost of ownership. In certain applications such as off-grid solar energy storage where the batteries are fully charged and discharged daily, it is not cost-effective to use current lithium-ion batteries due to short replacement life.
