Battery Essentials is designed for anyone interested in battery technology who wants to build solid expertise in battery chemistry, e-mobility, and stationary energy storage - and contribute to driving the energy transition.
Stay up to date in the automotive, electrical, chemical, or related industries, deepen your knowledge of e-mobility and battery technology, and play an active role in shaping the future.
You work with home storage systems or electric cars, want to understand battery technology properly, and prefer to take things into your own hands.
During your studies, you want to specialize in battery R&D, build or strengthen your fundamentals, and lay the foundation for a future-proof career with a positive impact on the planet.
There are tens of thousands of articles about batteries online, but many are misleading or contradictory. This makes it hard for beginners to get started and understand the topic properly.
Startups and research institutes announce new so-called “wonder batteries” almost daily. These claims are often difficult for non-experts to evaluate — and can easily be misleading.
In academic education, you encounter many theoretical concepts — but often without a real connection to practical applications. As a result, students are not prepared for everyday work in industry, and research frequently misses the real challenges companies face.
There are only a few battery textbooks — and the ones that exist are dry, overly theoretical, and quickly become outdated.
With the “publish or perish” culture, hundreds of irrelevant papers are released every day. Finding truly useful, high-quality literature is a real challenge.
… often doesn’t address industry-relevant problems and therefore doesn’t teach you what actually matters in real-world applications.
We need a place where all relevant information on battery technology is collected and classified.
You need teaching that focuses on real-world challenges in the battery and automotive industries — the knowledge that truly matters for a successful career.
You need a clear way to distinguish real innovations in battery technology from empty promises.
In 9 clear and structured chapters, you’ll gain a solid understanding of battery technology — all in one place and in just a few hours.
Each theoretical concept is supported by real-world examples, helping you not just learn but also classify and apply the knowledge. This significantly improves your chances of launching a successful career in industry.
Battery Essentials is updated regularly with new lessons and technologies — so you’re always up to date.
“Battery Essentials presents current battery knowledge in a clear, modern, and highly accessible way — far more effective than traditional textbooks.”

Tom Bötticher is a chemist by training, an expert in electrochemical energy storage, and a science communicator and founder.
I conducted research for Tesla, was trained by battery pioneer Prof. Jeff Dahn, published my work in leading scientific journals, and co-founded the battery start-up Litona, where we develop, produce, and sell next-generation sodium-ion batteries.
On YouTube, I share my experiences from the battery industry and provide exclusive insights for my community.
Now I’m excited to share the knowledge I’ve developed over many years — distilled to the essentials and explained in a clear, accessible way.
