Q: What are some of the driving forces in military system design
that will necessitate improvements in battery technology?
Sol Jacobs, VP and General Manager, Tadiran Batteries The modern battlefield is becoming more technologically advanced, incorporating the use
of remote wireless devices and communications.
The growing list of applications includes ground
sensors, wireless mesh networks, miniature UAVs,
smart munitions, and devices that monitor military equipment
and weapons systems, to name a few.
These applications typically exceed the performance
capabilities of consumer alkaline and primary lithium batteries
that don’t adequately support product miniaturization, suffer
from short lifespans, and offer narrow temperature ranges. For
example, wireless devices that draw low average daily current
are typically better suited for industrial grade lithium thionyl
chloride (LiSOCl2) batteries that deliver high energy density and
capacity to support product miniaturization, a low annual self-discharge rate to extend operating life, extended temperature
range, and high pulses capabilities to support two-way wireless
Similarly, industrial grade rechargeable lithium-ion (Li-ion)
batteries can outperform consumer grade Li-ion batteries in the
battlefield by delivering an extended operating life, high pulse
capabilities, and extended temperature range.
Applications designed for one-time use that draw high
continuous current, such as smart munitions, were once
powered by spin activated and reserve/thermal batteries: legacy
technologies that are overly bulky, expensive, and cannot be
activated unless exhausting all their energy, thus eliminating the
opportunity to periodic test for system readiness. To address this
problem, long-life lithium metal oxide batteries were developed
that provide an economical COTS solution, featuring very high
capacity and energy density to support miniaturization, up to
20-year shelf life, and ruggedized construction to survive shock,
vibration, high spin rates, and g-forces. Lithium metal oxide
batteries are also being utilized for miniaturized emergency
power so a crippled UAV can glide to a safe landing.
As remote wireless military applications continue to evolve,
intelligent battery-powered solutions will be required to achieve
maximized performance and value, while becoming increasingly
Zachary Sharpell, CEO, Sharpell Technologies
Increases in power, complexity, along with size and weight reduction are at the forefront of newly
developed military systems. Due to this innovation
in military devices, not only must battery cells
improve, but packaging in which multiple cells are
placed, must be redesigned from the most basic level.
With increased power consumption from new technology in
military systems, battery technology will need an increase in
energy density—the power stored per weight of the battery.
Keeping soldiers mobile and agile is a vital part of the winning
strategy—the less weight a soldier carries, the quicker and
further they can run. In terms of agility, battery technology
must shrink—this doesn’t mean a decrease in capacity, but
size. Smaller form factors for batteries equal small space
requirements, and coincides with the
decreasing size of new military technology.
The number of devices present on soldiers
has been increasing over the past two
decades, and will continue to increase as more
systems are developed. While these systems
are designed in part to protect soldiers,
the batteries powering such systems are an
opposition to protection. Li-ion batteries are
known for their instability and flammability
upon penetration (i.e., hit by a bullet). It’s
necessary that a safer battery chemistry be
used for upcoming military systems. The goal
of missions is to succeed, and that includes
ensuring the safety of our soldiers.
With the advent of augmented reality,
intelligent scopes, and even new versions of
radio, it’s important they are powered by
the best batteries available. The last thing we
want is our troops to go into the fight with
their state-of-the-art technology dead due to
an empty battery. ECN
