Almost a year into his new research partnership with Tesla, battery researcher Jeff Dahn has been hitting the talk circuit presenting some of his team’s recent progress. We reported last week on his talk at the International Battery Seminar from March and now we have a talk from him at MIT this week.

He went into details about why Tesla decided to work with his team and hire one of his graduate students, but he also announced that they have developed cells that can double the lifetime of the batteries in Tesla’s products – 4 years ahead of schedule.

Update: Dahn reached out to clarify that the cells in question were tested in the lab and they are not in Tesla’s products yet. expand full story

Historical data from Tesla’s current battery packs show about 5% capacity degradation after 50,000 miles (80,000 km) and the capacity levels off for about 150,000 more miles before hitting 90% capacity.

Those are already pretty good results, but Tesla aims to do better with Jeff Dahn, a renowned battery researcher and the leader of Tesla’s research partnership through his battery-research group at Dalhousie University.

The scientist and his team recently unveiled their latest research on a new chemistry that could enable even more cycles without significant degradation. expand full story

Since Tesla’s acquisition of SolarCity, the company’s mission slightly changed from “accelerating the advent of electric transport” to “accelerating the advent of sustainable energy”. The company wants to offer solutions throughout the entire energy production and consumption process.

At a conference last week, a Tesla executive explained the company’s vision for managing all that energy across all their products. expand full story

Tesla is putting continuous efforts into making its battery packs safer. We saw a great example earlier this year when we reported on Tesla setting fire to a Powerpack to test its safety features with impressive results.

In its latest effort, the company filed a new application for a patent for an apparatus and method for ‘charging batteries safely’. expand full story

A few years back, there was a lot of talk about Tesla potentially using a metal-air/li-ion hybrid powertrain to enable a longer range and faster charging in future vehicles. There’s no doubt that the company worked on such a system since they applied for several patents related to the tech, but that was mainly back in 2010 when they were still very much in the heavy development work for the Model S.

At this point, it looks like Tesla is very committed to li-ion batteries and metal-air doesn’t seem to be on the map anymore, but the company was recently granted another patent related to emerging battery technology. expand full story
