Under the leadership of "Battery Queen" Christina Lampe Onnerud, Cadenza Innovation is issuing licenses for lithium-ion battery architectures to manufacturers around the world.

Cadenza Innovation has developed a new design that improves the performance, cost, and safety of large lithium-ion batteries. Now, with an unusual strategy to spread the technology, the company is preparing to have an impact on industries such as energy grid storage, industrial machinery, and electric vehicles.

Cadenza did not produce batteries, but licensed its technology to manufacturers who produce batteries for different applications. The company also collaborates with licensees to optimize their production processes and sell new batteries to end users. This strategy ensures that the deployment speed and breadth of the company's technology, which has been in place for four years, are faster than if it had not been done.

Christina Lampe Onnerud, founder of Cadenza, was a postdoctoral fellow at the Massachusetts Institute of Technology (MIT) and a veteran of the battery industry. Her goal is to help drive the development of the industry as global demand for batteries reaches a turning point.

Lampe Onnerud said, "At that time (the company's) The crazy idea is to see if there is a different way to get in touch with this industry and help it embrace a new technology in existing applications, such as cars or computers. Our idea is that if we really want to have an impact, we can incentivize the industry to use existing funds to obtain better technology in the global market, becoming a positive component of this climate changing field

Considering this noble goal, this Connecticut based company has established partnerships with various levels of the battery supply chain organizations, including suppliers for industrial minerals, original equipment manufacturers, and end users. Cadenza has demonstrated its proprietary "supercell" battery architecture in Fiat's 500e model, and is completing a demonstration energy storage system for the New York Power Authority (NPA), the largest state-owned utility company in the United States, to use when its energy demand reaches its peak.

However, the company's most important partnership to date was announced in September with Shenzhen BAK Battery Company, one of the world's largest lithium-ion battery manufacturers. The two companies announced that BAK will start mass production of batteries based on Cadenza supercell architecture in the first half of 2019.

Supercell architecture award

Lampe Onnerud's extensive exposure in the lithium-ion battery field and world-renowned technical team have accelerated Cadenza's rise, but the fundamental reason for the company's success is simple: its technology has been proven to provide manufacturers with higher battery energy density while reducing production costs.

Most rechargeable lithium-ion batteries are powered by cylindrical metal sheets, known as "jelly rolls". In large batteries, jelly rolls can be made into large batteries to limit the total cost of the battery assembly, or they can be small enough to utilize more efficient battery designs to achieve higher energy density. Many electric vehicle (EV) companies use large jelly rolls to avoid durability and safety issues caused by tightly fitting small jelly rolls into the battery. If a jelly roll overheats, it can cause the entire battery to malfunction.

Tesla is famous for its use of small jelly rolls in the battery, which solves safety issues through cooling pipes, complex circuits, and spaced rolls, thus achieving longer driving distances. But Cadenza has obtained a patent for a simpler battery system called a "super battery" that allows small jelly rolls to be tightly packed in one module.

The key of supercell is a non combustible ceramic fiber material. Each jelly roll is put together like an egg in a carton. This material helps to control the temperature of the entire battery and isolate damage caused by overheated jelly rolls. The metal diverter wrapped around the flame retardant layer of each jelly roll and super monomer wall reduces the pressure in case of thermal events, which increases its safety advantage.

The enhanced safety enables Cadenza to pack the jelly tightly, thus improving the energy density. The simple design of the supercell utilizes many components currently produced at low cost and high output, thus reducing the production cost. Finally, each supercell module is designed with a click like Lego building blocks, so that manufacturers can easily adjust the size of the battery to meet customer needs.

In a grant program in collaboration with ARPA-E, an advanced research program in the United States, Cadenza's safety, cost, and performance characteristics have been validated. The program has cost the company nearly $4 million since 2013 to test the architecture.

When the supercell architecture was publicly unveiled in 2016, Lampe Onnerud said: "It can be used to expand the driving range of Tesla cars by 70%, making headlines. The goal now is to let manufacturers adopt this architecture."

Lampe Onnerud said, "There will be many winners using this technology, and we know we can deliver (safety, performance, and cost) requirements. It is up to the licensee to decide how they will leverage these advantages

At MIT, 'data speaks'

Lampe Onnerud and her husband Per Onnerud served as the Chief Technical Officer of Cadenza and held postdoctoral positions at the Massachusetts Institute of Technology before obtaining a doctoral degree from their home country, Uppsala University. Lampe Onnerud works closely with the professors of materials science and mathematics at MIT to engage in the laboratory work of inorganic chemistry, while Onnerud is engaged in research work in the Department of Materials Science and Engineering. This experience left a deep impression on Lampe Onnerud.

She said, "MIT is a very formative experience. You need to learn how to argue an argument so that data can speak. You only need to use data; there is no need to elaborate. MIT has a special place in my heart

Since then, Lampe Onnerud has maintained close contact with the college, participating in alumni meetings, giving guest speeches on campus, and serving as a member of the visiting committee of the Massachusetts Institute of Technology's Corporate Chemistry Department - all of which have achieved significant success in her career.

Lampe Onnerud founded Boston Power in 2004. Before the company moved its business to China in 2012, she became an internationally renowned battery manufacturer in the fields of consumer electronics, automotive and industrial applications, and also served as CEO. In the early stages of the company's establishment, after completing more than seven years of postdoctoral work at Lampe Onnerud, she realized the sustainability of community support from the Massachusetts Institute of Technology.

Lampe Onnerud said, "We started looking for some angel investors, and the first group to respond was MIT affiliated angel investors. We supported each other because we were often attracted to difficult problems. This is very in line with the spirit of MIT: we know that if we want to solve big problems, it will be difficult. So we enjoy working together

The high profile experience of Boston Electric Power earned her the Technology Pioneer Award at the World Economic Forum and the Annual Swedish Women's Award from the Swedish Women's Education Association. This also leads some people to believe that she is the "Battery Queen".

Just after leaving Boston Power, Lampe Onnerud and her husband began to design the supercell of Cadenza in their garage. They hope to create a solution to help reduce the world's carbon consumption, but they estimate that if they manufacture their own batteries, they can produce up to 1 billion batteries every 18 months. So they decided to switch to the method of technology licensing.

From a business perspective, this strategy is a trade-off: Cadenza needs to raise much less capital than Boston Power, but it will allow licensed companies to generate both top and bottom line growth while achieving a certain proportion of sales. Lampe Onnerud is clearly pleased to leverage her global network and share benefits to maximize Cadenza's influence.

Lampe Onnerud said, "My hope is that we can gather people around this technology and do something truly important, such as reducing carbon consumption, eliminating nitrogen oxide emissions, or improving grid efficiency. This is a different way of cooperation, so when an element of the biological system wins, we all win. This is an inspiring process
