Cathode technology doubles lithium-ion battery capacity, slashes costs

BioSolar’s novel high capacity cathode is engineered from a polymer, similar to that of low cost plastics and can hold two electrons for each molecular unit. Instead of conventional cathodes that use lithium-ion intercalation chemistry, which is inherently slow, the company’s technology exploits the fast redox-reaction properties of polymers to enable rapid charge and discharge.

Based on the company’s internal analysis, the battery is claimed to be capable of doubling the range of a Tesla automobile, cost four times less, and exhibit faster charging times and provide longer battery life.

BioSolar claims the battery can potentially break the $100/kWh cost barrier needed for mass market adoption of energy storage.

Dr. David Lee, BioSolar’s CEO said: "A battery contains two major parts, a cathode and an anode, that function together as the positive and negative sides. Today’s state-of-the-art lithium-ion battery is limited by the storage capacity of its cathode, while the anode can store much more. 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 two days straight, or store daytime solar energy for nighttime use."
