Maxell 3V Micro Lithium Button Coin Cell Battery

Maxell’s introduction of the CR Cylindrical battery was first released commercially in 2005 as an innovative battery for industrial use.  Although the exterior design appeared the same as conventional cylindrical batteries, the internal spiral wound electrode with both high energy density and high load durability together was unique.  Conventional electrode designs such as Spiral type (wound electrode) and Bobbin type were commonly used, however, with the evolution of more high-power electronic components, traditional batteries could not support the energy or pulse requirements of emerging market applications.  With Maxell’s introduction of their CR Cylindrical technology, they achieved the demands of these electronics, supporting future generations of smart meter technology and other IoT applications with high capacity, extended life and heavy discharge current requirements.

As shown on the chart below, Spiral type has its advantage in high current load performance due to its large electrode, but there is a trade-off in energy density. The opposite trade-off occurs with Bobbin type with higher energy density, but not feasible for higher current discharge performance.
