Scientists at a London-based company have come up miniature solid-state battery to power blue tooth devices. Ilika, a materials and solid-state battery innovations company, has designed a miniature solid-state battery called the Stereax M250 aimed at the IoT market. 
Using primary batteries can offer a cheap option but need changing regularly. Rechargeable coin cell or supercapacitors are another solution but they are bulky, can have a risk of leakage, and are not so good at efficiently storing the current picked by energy harvesters.”
The Stereax M250 offers benefits over current coin cell batteries like CR2032 as the M250 battery is designed to last up to 10 years. Understand they also represent 50% of the volume for the same power and 1/10th of the leakage current as compared to CR2032 cells, the company said.
They are designed to function at higher temperature ranges and are more moisture-resistant.
