BATTERY PRODUCT APPLICATIONS

improve the energy density of batteries by eliminating electrochemically inactive binders

In building our electrodes, we use new material formulation that eliminates binders, and a scalable electrode manufacturing process to deliver binderless electrodes that increases the energy density of batteries. We improve the energy density of batteries by eliminating electrochemically inactive binders and conductive materials that reduce the specific capacity and energy density of the active materials. The binder-free electrodes exhibit excellent electrochemical performance due to their high ion/electron conductivity and close contact between the conductive substrate and the active material. Our innovation is material agnostic so we build high performance cathodes and anodes using both existing and new battery materials. Our first battery product is a proprietary high-capacity anode, Binder-Free FE^TM Anode. More information about this anode is provided below:

A1. Binder-Free FE^TM Anode

SmartEnergi’s Binder-Free FE^TM Anode has about 3 times the capacity of conventional graphite anode (1,000 mAh/g). This anode uses raw materials that are 9X cheaper than conventional graphite anode materials, abundant and domestically produced, allowing us to provide supply chain resilience for anodes used in Li-ion and other advanced batteries. Moreover, our anode has high thermal stability (with onset decomposition temperature of the nanocomposite electrode coating above 600 oC), and significantly improved safety compared to competing anodes such as graphite, silicon, silicon-graphite composite, and Li-Metal.

high-performance Binder-Free FE^TM

Our high-performance Binder-Free FE^TM anode allows us to initially plant our feet firmly in the Li-ion Battery world because it can be paired with a variety of conventional cathodes. For instance, pairing our Binder-Free FE^TM Anode with conventional cathode such as NMC811 would improve energy density by 60%. Our anode also has durable high-rate capability, allowing us to support true fast charging of electric vehicles – fully charge in 6-12 minutes (5C to 10C)- with minimal capacity degradation.

Summary of the advantages that automakers using this product can expect to get include:

A2. NEXT GENERATION CATHODE

SmartEnergi is also applying our material and manufacturing process innovation to develop several next generation cathodes, including a new high-capacity iron-based cathode that could reduce the cost of the cathode by more than 300% versus NMC cathode, and increase the energy density by 100% when paired with our proven proprietary Binder-Free FE^TM Anode. More significant, it would completely disrupt the Li-ion battery supply chain because it would allow us to pair this advanced cathode with our Binder-Free FE^TM Anode to power electric vehicles and other battery applications without depending on huge portions of current Li-ion battery materials (No Lithium, No Nickel, No Cobalt, No Magnesium, and No Graphite)!
