Thin and flexible batteries

Whilst existing battery technologies such as lead acid and lithium-ion batteries will dominate the battery market in the following 10 years, advanced and post lithium-ion batteries given the right conditions can potentially take a considerable dent of about 10% of whole battery market by 2026.

A new design strategy has emerged for making batteries flexible.

After years of slow progress from small companies, flexible batteries now have the attention of big brands such as Apple, Samsung, LG Chemical, Nokia and STMicroelectronics, who are set to drive the flexible battery market from US$ 6.9 million in 2015 to over US$ 400 million in 2025 according to IDTechEx Research.

This article shares some of the research carried out for the new IDTechEx report, "Batteries and Supercapacitors for Smart Portable Devices 2013-2023: Markets, Technologies, Companies"

Wound (rolled) rechargeable batteries and supercapacitors (Electrochemical Double Layer Capacitors) are similar in construction.

Fuel cells were originally considered to be replacements for internal combustion engines used in traditional vehicles and replacements for traction batteries used in pure electric vehicles.

Electronics and electrics are becoming ubiquitous, the devices appearing on and in higher and higher volume products including e-labels and e-packaging. This calls for different forms of battery, capacitor and other energy storage because priorities such as environmental credentials, thinness and compatibility with energy harvesting (eg. solar cells) come to the fore alongside life and cost.

Plug in hybrid electric cars are now prioritised by most major car manufacturers. Pure electric on- road cars are prioritised by Nissan and a host of vibrant start up companies, they have one thing in common. The cleverest, most expensive part of their planned vehicles is increasingly the traction battery.

While some involved in OLEDs and OTFTs are moving out of the business of printed and potentially printed electronics, work on inorganic materials and compounds is increasing. The IDTechEx Printed Electronics Asia event in Tokyo will give a balanced view with many presentations being World firsts.
