This webinar is part of a 1-hour webinar series hosted by the Cross-Sector Battery Systems Innovation Network. Each webinar focusses on Batteries for Defence.
Building on the successful launch of the Cross-Sector Battery Systems Innovation Network in late September 2020, this webinar series will look into the opportunities and trends for Batteries in Defence, Maritime and Rail. Each session will bring together experts looking at the supply and demand side for batteries, technical requirements and explore how these wide range of sectors can decarbonise through batteries.
The Cross-Sector Battery Systems Innovation Network will develop a self-sustaining and collaborative community of technology developers and end-users from multiple sectors. The CSBS Innovation Network community will share knowledge around the challenges and opportunities associated with batteries for a broad range of sectors such as aerospace, rail, maritime, stationary storage and other niche applications.

5. Cross-Sector Battery Systems Innovation Network - Mission
To create an open and collaborative cross-sectoral community for researchers and innovators
in battery manufacturing (including next generation batteries), the related supply chain and end-
users. The community, which will be served by a dedicated online space, will help to:
open new markets for the battery industry, by introducing this community to new sectors,
thus support the growth of UK economy
promote innovation in batteries by identifying technical gaps for their introduction to
various sectors
help decarbonise a wide range of end-users from rail, maritime, aviation, construction etc.
by enabling the adoption of batteries, thus support the Net Zero agenda.
8. Why is defence interested in batteries?
Batteries are a key enabler of many defence capabilities
Battlefield becoming more electronic and digitised with platforms
becoming more electric
Increased need for power and hence batteries
Defence no longer the major investor in batteries
– Need to adapt and adopt commercial technologies where possible
– Leverage civilian research
– Seek dual use technologies
– Niche research where necessary for specialist systems
Introduction

9. Land
– Hybrid electric vehicles
– Soldier systems
– Unmanned ground vehicles
– Base infrastructure
Maritime
– Hybrid large batteries for ships
– Fast boats (very high power)
– USVs (Unmanned Surface Vessels)
– UUVs (Unmanned Underwater Vehicles)
Aerospace
– UAVs (Unmanned Aerial Vehicles)
• Fixed wing
• Rotary wing (power demand higher)
• Batteries appropriate at nano, small and perhaps medium scale
– Emergency & back up batteries for manned aircraft
Specialist
– Thermal batteries , very high power, 20 yr shelf life
– High energy primaries
Markets/Applications

OFFICIAL
10. Defence uses lots of different
batteries
Rechargeables
– Li-ion
– NiCd
– NiMH
– Lead acid
Primaries
– Zn/MnO2
– Li/FeS2
– Li/SO2
– Li/MnO2
– Li/SOCl2
– others

11. Technical targets depend on application
Broadly similar to the Faraday targets - the differences may be in the acceptable compromises
– Everyone wants a battery which is lightweight, cheap, safe, high cycle life, high energy, high power, etc.
Defence may weight some parameters higher than civilian applications
– Temperature of operation (Defence Standard 00-35 - ENVIRONMENTAL HANDBOOK FOR DEFENCE MATERIEL)
• No single temperature range defined but a wide range is preferred (e.g. -20 to +70oC, perhaps colder for some applications)
• Not just operational temperature but storage temperatures may be harsh as well
– May rate specific energy more important than cost or cycle life in some cases
• At one extreme defence still uses primary batteries
• But must still be affordable
• What is battery cost compared to platform cost?
• What is the price of overmatch?
– Most land and air systems - weight is more important than volume
– Most maritime, and especially subsea, volume is more important than weight
– Shock tolerance (bump & vibration)
– Electromagnetic compatibility (EMC) must not interfere with or be interfered by local RF systems
Safe and reliable
Defence battery requirements

OFFICIAL
12. Increased battery storage can
provide overmatch
– Increasingly the case as more
platforms are battery powered
– E.g. UAV increased surveillance
range – see enemy before they
see you
– RF sensing or jamming
– Or increased persistence
• If blue capability can outlast
red capability then an
advantage
Battery Overmatch

OFFICIAL
13. Safety is a relative parameter
MOD (like everyone) wants safe batteries
But in many cases also needs maximum performance
Everything is a balance and compromise
ALARP is key
– Risk must be As Low As Reasonably Practical
– Means in some cases if the requirement warrants it we use very high energy Li metal primary batteries
– In other cases still use lead acid batteries
Really MOD wants safe, high energy cells
Take a systems approach
– Even volatile cells can be safe if packaged correctly
– But inherently safer cells allow more freedom with packaging etc.
Where we may differ from civilian requirements is the level of expected abuse
– e.g. bullet, fragmentation penetration may be more likely
– shock and vibration likely to be harsher
Safety

OFFICIAL
14. Can defence adopt emerging technology before mainstream markets
– E.g. when perhaps cycle life or cost is not ready for EVs etc.
– Or even technologies that have promise but can’t find a mainstream market
Can defence make wider use of emerging civilian standards or
Can civilian applications make wider use of standard defence batteries
– Defence Standard 61-21 and supplements
– US stds
– NATO stds
Where are the overlaps?
– Perhaps only minor modifications to meet wider markets
Ideas for Cross sector collaboration
14
OFFICIAL
15. Batteries dominate electrical energy storage
But other technologies of interest
– Capacitors/ supercapacitors
– Fuel cells
– Renewables (wind, solar)
Other areas
15
OFFICIAL
17. Exploitation
– Defence (MOD and Industry users) may be able to exploit products before
they meet all the needs of mainstream markets
– Could be a stepping stone to wider opportunities i.e. defence cell/battery
volumes may typically be lower than commercial markets
• Help with the path to scale up
– Export Market is strong: NATO and international Defence interest in better
energy sources
Exploitation
17
OFFICIAL
18. Defence increasingly interested in batteries
Keen to align with civilian initiatives where possible
Defence has a very wide range of requirements and applications
– Need battle winning capability
Finally: The ‘Cross-Sector Battery Systems Innovation Network’ is a good
platform to discover more on Defence context and for Defence to
understand wider industry

BAE Systems Research
Electric Propulsion
• In an effort to contribute to net zero
carbon targets, research is being
conducted into bringing
developments from adjacent electric
propulsion markets into the military
domain.
Structural batteries
• This new technology stores the electrical
energy within the physical structure of a
device – reducing or eliminating the need
for traditional batteries. This could
represent a significant reduction in
weight, bulk as well as minimising the
burden and cost of carrying spares.
• To develop the technology, BAE Systems
scientists merged battery chemistries
into composite materials that can be
moulded into complex 3D shapes and
form the structure of the device itself.
This structure can then be plugged in
when it needs recharging or can utilise
renewable power sources, such as solar
energy.

The Future of Batteries for BAE Systems
Key Requirements for us:
• SAFETY
• Operational Assurance
• Lifetime
• Weight/volume - Limited space on platforms
Energy storage is a key capability in a number of BAE Systems’
products, including underwater vehicles and soldier systems.
It is also becoming a key part of running our sites and large platforms.
