Applications & Use‑Cases
The Murata NC1 is well suited to the following applications due to its cylindrical 18650 form factor and high energy density performance.
Aviation: Requires high specific energy for extended flight duration, high power-to-weight ratio for climb performance, and reliable operation across wide temperature ranges at altitude.
E-Mobility: Requires balanced energy and power density for range and acceleration, high cycle life for daily use, and robust calendar life to ensure long-term reliability.
Energy Storage: Requires stable cycle life across deep discharge profiles, reliable calendar life under float conditions, and consistent capacity retention over extended deployment periods.
General Applications: Suitable for applications requiring reliable lithium-ion performance with proven cycle life, consistent capacity delivery, and operational safety across diverse use cases.

Motorsports
McMurtry Automotive: Faster cell evaluation
McMurtry Automotive used The Voltt and validated cell models to evaluate the transition from the Molicel P45B to P50B during early pack concept development.
Side by side modelling enabled rapid comparison of electrical and thermal behaviour, avoiding lengthy physical test campaigns. This approach reduced cell evaluation time by seven months, allowing the team to lock in cell selection and pack assumptions earlier while lowering technical risk and accelerating vehicle development.

Manufacturer Background
Murata
Murata is a Japanese manufacturer of cylindrical lithium-ion cells for power tools and mobility
Murata Manufacturing is a Japanese electronic components group headquartered in Kyoto that entered lithium-ion cell manufacturing by acquiring Sony's battery business in 2017. The acquisition brought the US-series cylindrical cells, including the VTC family, which had already established a reputation for high continuous discharge in power tools and electric two-wheelers. Murata continues production of 18650 and 21700 cells at plants in Japan, Singapore and China, with model codes carrying the US prefix followed by the cell diameter and length. The range spans high-power VTC cells and higher-capacity variants for energy-led applications. Its position combines Sony's cell heritage with the quality systems of a major components manufacturer.
