New Chemistry for Long-lasting Batteries

The electric vehicle market continues to build momentum every year, with consumers around the world growing more interested. But in order for EVs to pave the way for the future of transportation, more efficient, longer-lasting batteries will need to be developed.

That’s where ECS member Jeff Dahn, leader of Tesla’s researcher partnership through his Dalhousie University research group, comes in. Recently, Dahn and his team unveiled new chemistry that could increase battery lifecycle at high voltages without significant degradation.

This from Electrek:

At the International Battery Seminar & Exhibit in March, Dahn presented his new research to improve the chemistry of NMC Li-ion in order to limit the gasses generated by the cells when operating at high voltage.

The improved cells that they created from their research have performed exceptionally well after over 1,200 cycles.

If made into a car battery pack, 1,200 cycles would translate to roughly 300,000 miles (480,000 km) – meaning that a battery pack could still retain about 95% of its original energy capacity after ~300,000 miles – or 25 years at the average 12,000 miles per year.

Dahn will also bring his experience in industry and science to ECS’s 2017 OpenCon, which the Society will host as a satellite even on October 1 in National Harbor. OpenCon is a conference and platform for the next generation to learn about open access, open education, and open data. Additionally, participants can develop critical skills and catalyze action toward a more open system for sharing the world’s information—from scholarly and scientific research, to educational materials, to digital research data. Dahn’s talk will focus on “Open and Industry.”
