Microtron has built a revolutionary graphene-based battery using Composite Charge Cache technology that can deliver high power and high energy density, with long cycle life and nearly instant charging.
Current battery approaches focus on trying to reduce the inherent limitations of electrochemistry; however, when it comes to power requirements, chemical approaches will always be slow as the rate of a chemical reaction is hard to increase without serious complications related to safety, performance, and product life.
Unsurprisingly, most of the commercial R&D in energy storage of the last century has focused on engineering around the inherent limitations of the chemistries to mitigate the drawbacks. While these efforts have brought tremendous advances, the efficient use of batteries in many applications requires centering the entire commercial operation on the limits imposed by the battery bottleneck, which brings additional costs and complications.
Microtron’s technology solves the critical energy storage dilemma while providing additional technological benefits to users. These benefits enable OEMs in the forklift and golf cart industries to differentiate their products and provide superior value to their customers.
Unlike conventional ultracaps using Activated Carbon, Microtron’s storage cells use graphene. The higher surface area of graphene allows Microtron to deploy ultracap cells with capacitance values of up to 140,000 farads vs the 3,000 farads in most ultracapacitors on the market today.
Microtron's proprietary energy storage cells embed both capacitive and chemical storage layers. This provides the power handling capabilities of capacitive storage while minimizing leakage and self-discharge.
The combination of very high capacitance cells and cell-level integration of lithium-ion requires the use of a software-managed system of electronics for managing the discharge current and for the balancing and stability of the graphene cells. Microtron has refined a cell balancing solution that allows the system to attain both high energy density as well as flexible power output.
Microtron’s solutions outclass both lead-acid and lithium-ion storage technologies on charge time, cycle count life, discharge depth, round-trip efficiency, and power density. This superior performance offers an improvement in energy density over lead-acid that is comparable to the energy density performance of lithium-ion chemistry, without the same drawbacks as lithium-ion. The total cost of ownership is highly competitive with lithium-ion and lead acid chemistry.
