Marca Doeff, a staff scientist in the Energy Storage and Distributed Resources Division at Lawrence Berkeley National Laboratory and chair of the ECS Battery Division, discusses the future of batteries. Doeff covers advancements and developments, notable contributors and leaders, corporate sponsors and supporters, upcoming meetings and awards, all within the battery field.
What are a few current areas of battery research the division is focusing on?
Anything having to do with lithium-ion batteries, since they are turning out to be the real workhorses of the battery world. While the chemistry is fairly mature at this point, there is still a lot of work going on in silicon anodes, trying to find better cathode materials, and improving electrolytes.
There are also intense efforts going into recycling, advanced manufacturing, and understanding and mitigating safety issues. The so-called “Beyond Li-ion” systems have been the focus of a lot of research in recent years. The ideas for many of these have been around for a while-like lithium metal batteries with sulfur cathodes, or sodium ion (one of my favorites), solid state batteries, or even multivalent chemistries, but the revolution in battery science over the past 25 years or so means that it is worthwhile taking a fresh look at these systems.
