“Thousands of factories are needed” – Ludvika-born battery entrepreneur Christina Lampe Önnerud on Borlänge visit

DECEMBER 2, 2022

On Thursday, battery entrepreneur Christina Lampe Önnerud visited Dalarna Science Park in Borlänge to give a lecture on the energy of the future. She believes that it will require an awful lot more batteries than can be manufactured today to meet all needs both in terms of mobile phones, laptops, electric cars and large energy storage to stabilize the electricity grid in the future.

“Thousands of battery factories will be needed, there are already hundreds,” says Christina Lampe Önnerud, from Dalkulla, who herself built up a large battery industry in the US, where she has lived for many years.

But she does not foresee any immediate technological change in terms of the structure of the batteries. The Nobel prize-winning lithium-ion batteries found in everything from mobile phones to electric cars today are here to stay as they can be adapted in many different ways.

– The wealth that exists will probably last my entire lifetime and perhaps my children’s lifetimes, she says.

And then, of course, we ask how things went with the proud plans she herself had about 12 years ago to build a battery factory in her old hometown of Ludvika.

You can hear the answer to that question in the clip and more about how much the battery market is expected to grow in the next decade.

Battery Safety: An Explosive Issue | Christina Lampe-Önnerud | EDU2022

Dr. Lampe-Onnerud delivers a thought-provoking talk on real-world solutions based on a first principles approach that can eliminate the explosions that continue to plague the battery industry, particularly in EV and utility grid applications. She illustrates how safety has historically been deprioritised, often in favour of cost, resulting in battery energy storage systems (BESS) that cannot respond in time to prevent explosions and fires.

Carderock analysis of the Cadenza technology by the US Consumer Product Safety Commission

The Cadenza Innovation design is independent of subcomponent choice, meaning it could be completely compatible with any desired anode, cathode, electrolyte, or separator material. Even when subjected to an internal short circuit (produced using the NASA and NREL developed internal short circuit device) supercells produced using the Cadenza architecture and a standard LIB chemistry did not undergo propagating thermal runaway (Figure 33) (67). Testing of modules containing six supercells in series conducted at NSWCCD showed that overcharge, nail penetration, external short circuit, crush and over temperature testing all showed either no thermal runaway, or thermal runaway occurred only under extreme test conditions (crush above 100 kN load and over temperature > 200C). Development of the Cadenza super cell and evaluation by NSWCCD was sponsored by the Advanced Research Project Agency- Energy (ARPA-e).

World Economic Forum – The Speed of the Energy Transition

Will the global energy transition from fossil fuels to sustainable energy be gradual or rapid? This
key issue for the 2020s has profound implications for governments, energy producers, technology
providers as well as industrial and private consumers. But, more importantly, the difference between
a gradual and rapid transition will determine the climate future of humanity. A gradual transition
will mean that the goals of the Paris Agreement will be badly missed. A rapid transition will give
humanity a chance to meet the goals of the Paris Agreement and keep temperature well below 2
degrees Celsius.
