AC Biode


We will develop the first-ever standalone AC battery by "Biode"

Our power storage solution will be licensed to battery manufacturers/parts manufacturers as the world’s first-ever standalone AC (Alternating Current) battery using a “Biode”.
Biode has both the characteristics of an Anode and a Cathode and allows our AC battery to be safer and approximately 30% more compact than regular DC (Direct Current) batteries.
The production of our AC battery utilizes existing materials and production lines; therefore, we can reach the market in the short term and we will be faster than other developments using new materials or all-solid-state batteries.

Description
We will develop the first-ever standalone AC battery by "Biode" with Cockcroft-Walton Multiplier

1) Battery is up to 30% more compact: Our battery is up to 30% more compact than the conventional DC battery. In addition to anode and cathode, we have developed Biode, which has both the characteristics. The clever utilization of the Biode and the elimination of conversion equipment will serve to reduce weight and size. 2) Very simple. Use the existing materials/production lines: We will utilize all the existing materials and production lines of batteries and circuits. The production cost of Biode is same as that of an anode, manufactured by the existing roll-to-roll method. 3) Safer than the conventional Li-ion batteries: Voltage within the battery cells is divided by the Biode, leading to safer operations. For example, while there is 4V between anode and cathode within the conventional Li-ion battery, Biode can divide the voltage into 2V each and at the same time increase the battery capacity. Even organic electrolytic liquids do not burn under 3V. 4) Very quick- Trials start in one year: We plan to start trials for commercialization in 1 year after a seed-fund raise of 500K USD. 5) Reduce conversion losses By eliminating the need for conversion, the associated losses can be reduced. 6) Lower electrical resistance (longer life/safer): Quality of electrode particles vary a lot. The quality of the electrode particles is a limiting factor for DC batteries; however, it is not a limiting factor for AC batteries (see illustration below). The AC Biode, therefore, can perform better in terms of battery life and safety

Description
We will develop the first-ever standalone AC battery by "Biode"

The battery demands for electric vehicles (EVs), e-scooters, drones, electric airplanes (EAs) and others continue to increase significantly. According to a report by Markets and Markets (US), the world market cap for mobility batteries is estimated to be 17 billion USD by 2021 and its CAGR from 2016 to 2021 is expected to be 4.2%. We estimate that such growth in the mobility business brings a need for longer battery ranges and safer use so that technology can be fully embraced by users, however, current battery capacities are insufficient to meet the needs of the future users. Additionally, commercialization of the all-solid-state batteries is expected, but its realization will take years, which is the case of developing new materials. Our solution – the first-ever standalone AC Battery by “Biode” Currently, the battery electricity source is only DC, therefore, we need to convert from AC to DC every time batteries are charged and in the case of AC motors and additional conversion is required, resulting on electricity losses of up to 35%. Therefore, we have been developing a solution to avoid or optimize this two-time conversion. Capitalizing on our 25 years of experience and 5-years of research, we have developed the first-ever standalone AC battery (patent-pending). The general public has begrudgingly accepted that the battery electricity source has to be DC ever since Alessandro Volta developed a primary battery in 1800. Although it is true that it makes sense to use DC batteries to use lower power devices such as lights, radios or smartphones, battery applications for EVs, drones or EAs are more power intensive and DC batteries have become insufficient for the extended use these devices require. In these cases, AC batteries are more efficient and easier to control than the conventional DC batteries. Our innovative technology has the following 6 advantages: 1) Battery is up to 30% more compact: Our battery is up to 30% more compact than the conventional DC battery. In addition to anode and cathode, we have developed Biode, which has both the characteristics. The clever utilization of the Biode and the elimination of conversion equipment will serve to reduce weight and size. 2) Very simple.
