EnerG2 Dramatically Improves Overall Li-Ion Battery Performance

EnerG2 is harnessing its proprietary Carbon Technology Platform (CTP) to produce engineered high-purity carbon materials for applications in lithium-ion batteries.

Lithium-ion batteries are at the forefront of portable energy storage. Improvements in these battery technologies are expected to continue to drive increases in energy efficiency in a variety of applications. The economic opportunity created by such improvements is clear, given the host of global industrial companies that are already deeply involved in this area.

Adding to this effort, EnerG2’s customized carbon products for the Li-ion battery industry have the potential to dramatically improve overall battery performance. With a greater-than 30 percent increase in storage capacity and a simultaneous improvement in the charge and discharge rate, Li-ion batteries containing EnerG2 carbons can change the dynamic of this rapidly growing and valuable industrial sector.

The benefits of EnerG2’s carbons in Li-Ion batteries will be:
- Up to twice the reversible capacity of graphite anodes
- Higher rates of discharge capability, which delivers a battery with much higher power ratings
- Sloping discharge profiles, which enable a simple assessment of the battery’s state of charge

Further, traditional hard carbon anodes – the incumbent competitive technology – typically require more energy to charge the battery than what is released on that battery’s first discharge. This inefficiency has limited the adoption of these anode materials.

EnerG2 has delivered all of the benefits of a hard-carbon anode without the constraints by deploying its CTP to solve the problem. The CTP’s iterative approach to engineered carbon development and manufacturing rapidly produced a cost-effective solution. The precision and speed with which a potential solution was identified was unprecedented. “We definitely have an advantage in hard carbons anodes because of our Carbon Technology Platform,” explains Dr. Aaron Feaver, Co-Founder and CTO at EnerG2.

“We can rapidly fine-tune our carbons by iterating through material improvements in ways that others can’t. For example, our hard-carbon innovations can change acceleration profiles and battery recharge rates, while at the same time we can continue to iterate on materials that can someday enable longer electric vehicle ranges.”

EnerG2’s ability to fine-tune materials during production – cost-effectively – is just one of the benefits that the company offers to its customers.

“Until now,” adds M. Stanley Whittingham, Professor of Chemistry and Materials Science and Director of the Institute for Materials Research at SUNY-Binghamton, “no one did a good job at this in a truly scalable way. But EnerG2 has changed that. The company’s Carbon Technology Platform also really helps increase the speed of the process and the expansion of capacity, which are critical in today’s market. Furthermore, there is absolutely no next generation obsolescence issue with EnerG2.”
