Before Battery Essentials

What holds you back in everyday life and at work

01

Information without direction

The internet is full of tens of thousands of articles about batteries, but many are misleading or contradictory. You struggle to find a starting point and build a clear understanding.

02

Hype without perspective

Promising new battery technologies are announced all the time. Often, the hype offers little that helps you move forward. You struggle to put these claims into perspective.

03

Practice without the basics

When working with energy storage systems and electric vehicles, you lack the theoretical foundations to really understand them.

04

Theory without practice

In academic education, you encounter many theoretical concepts with no connection to practical applications. This leaves you unprepared for everyday work in industry and working on topics that miss its real challenges.

05

Data without insight

You have access to battery test data, but don’t know what it tells you or how to evaluate it.

After Battery Essentials

You understand how batteries really work.

You see more than measurements and problems: you understand the connections behind them and recognise the factors that influence performance, lifespan and safety.

You can put developments in context.

You know where to find reliable information and how to assess it. You understand what is behind new technologies and can distinguish real progress from big promises.

You know what to do next.

Whether you are working on your next battery project, advising customers and friends or buying an energy storage system: you ask the right questions, contribute with confidence and make informed decisions.

The problem with traditional learning methods

Textbooks

There are only a few battery textbooks — and the ones that exist are dry, overly theoretical, and quickly become outdated.

Reading papers

With the “publish or perish” culture, hundreds of irrelevant papers are released every day. Finding truly useful, high-quality literature is a real challenge.

Fundamental research

… often doesn’t address industry-relevant problems and therefore doesn’t teach you what actually matters in real-world applications.

Training sessions and lectures

They are often expensive and require considerable time and planning. Instructors may know their subject well but struggle to explain it clearly.

What you get here

01 / 04

Structured & clear explanations

We start from the very beginning and quickly take you from “I have hardly any prior knowledge” to “I understand batteries in detail”. In 9 clearly structured chapters, you build a solid understanding in just a few hours, all in one place, making it easier to get started in the world of batteries.

02 / 04

Practical and relevant to everyday life

We explain every theoretical concept with real examples, so you can not only gain information but also evaluate and apply it. This improves your chances of finding a good job in industry.

About the author

Tom Bötticher

Hi, I’m Tom.

I combine battery research and industry experience with ten years of science communication. So you can understand complex connections and put your knowledge into practice.

As a chemistry graduate, I specialised in battery storage early on: at the MEET Battery Research Center in Münster, then with battery pioneer Prof. Jeff Dahn at Dalhousie University in Canada. In collaboration with Tesla, my team and I identified a cause of unwanted self-discharge — a finding with significant, direct benefits for battery manufacturing that attracted worldwide media coverage. Our work was published in leading journals such as Nature Materials.

I also know the practical side as co-founder of Litona: in Ulm, Germany, we develop high-performance energy storage based on sodium-ion technology.

On my YouTube channel, I reach over a million viewers each month and more than 150,000 subscribers. I make battery technology and electric mobility accessible through explanations that are scientifically grounded, clear and entertaining.

My goal is to help shape the transition to a sustainable future, strengthen Europe’s technology landscape and inspire enthusiasm for science.

That is how Battery Essentials came about: I distil my knowledge into the essentials, explain connections step by step and link theory to real applications. So you can truly understand batteries and put your knowledge to work in everyday life and your career.
