The Road to Commercialization of Thin-film, Flexible and Printed Batteries

Dr Xiaoxi [email protected]


Dr Xiaoxi He covers energy storage, printed electronics and photovoltaics at IDTechEx. Xiaoxiobtained her PhD in Cavendish Laboratory, University of Cambridge, where she worked on organicphotovoltaics. Prior to that, she completed her MSc at the University of Ulm (Germany) on advancedmaterials and her BSc degree at Shandong University (China). Xiaox i has authored severalpublications in leading peer-reviewed journals. Xiaoxi speaks Chinese (Mandarin) and English.

Xiaoxi br ings a wealth of technical expertise to IDTechEx. She has focused extensively on thetechnology and commercial aspects of thin, f lexible or pr inted batteries, and is now an opinionleader in the industry. She also leads our coverage and analysis of high-tech innovation in China,regularly interviewing the key Chinese innovators and speaking at key conferences.

Xiaoxi has extensive consulting exper ience. She has helped our clients to form a technologyecosystem to commercialize a wearable product that requires a battery technology with a specialform factor. She has also helped our clients identify how their nanomaterial can deliver value inadvanced and post lithium ion battery technologies. She is now focused on key innovations thatenable flexible personal computing devices.

Focusing angles of next-generation batteriesThese terms focuses on different aspects that differentiated from traditional batteries.There are some overlaps meaning a battery may have several features

Thin

• Based on battery thickness

• E.g. thin-film battery

Micro- and Large-area

• Based on footprint• E.g. micro-battery, large-area battery

Flexible

• Based on the mechanical properties

• E.g. flexible, stretchable, foldable, rollable and bendable batteries

Novel Form Factor

• Based on form factors• E.g. needle battery

Transparent

• Based on optical properties• E.g. transparent battery

Printed

• Based on manufacturing method• E.g. printed battery

Post and Advanced Lithium-Ion

• based on material selection• E.g. solid-state battery, silicon anode, lithium-sulfur, etc.


Future Direction of Battery Development

Moment of directional change

Further R&D of new materials, chemistries and battery systems, as well as increasing existing battery performance

• Reduce energy consumption • Develop charging methods such

as wireless charging, rapid charging, integration with other energy harvesting, etc.

New applications:Enabled by battery cost reductionEmerging market: When special features are required that conventional batteries do not

Technology Status

Small volume production

Available, mostly customized Prototypes available Research to prototype Research Very early stage


Mismatch between technology push and market pull

• Development of printed electronics• Development of other flexible components for wearable and medical applications

• Discovery of new materials for electrodes, electrolyte, current collectors and packaging, etc.

• Development of new manufacturing methods including printing techniques

• New device structural designs

Technology Push

• Electronic gadgets are getting smaller, thinner and lighter, requiring new power source

• With the development of wearable technologies, energy sources used for wearable devices are becoming one of the major problems

• Medical/fitness devices are seeking batteries with special form factors and features.

• Internet of Things require billions of connected devices. Thinner and smaller batteries are needed accordingly
