Although similar to conventional batteries, micro batteries are made of thinner materials such as nanometers or micrometers. These batteries are developed by depositing or printing the materials on a thin film substrate. Micro batteries are intrinsically safe compared to conventional batteries as they are manufactured using all solid-state materials.
The micro battery market was valued at USD 128 million in 2019 and is expected to reach USD 631 million by 2025, at a CAGR of 30.4% between 2019 and 2025. Factors such as growth in the adoption of wearable devices, inherent advantages of micro batteries, need for compact batteries in medical devices, and increasing demand for thin and flexible batteries in IoT devices are driving the growth of the micro battery market.
Cymbet Corporation (US) and STMicroelectronics N.V. (Switzerland) are the 2 key players in the micro battery market.
