EV Batteries and Energy Storage
What is Energy Storage and Batteries and Why Does it Matter?
Energy storage and batteries are critical components in the electrical grid. Battery Energy Storage Systems (BESSs) enable producers to collect energy from inconsistent power generation sources like solar and wind and feed the network at a more consistent rate or at high demands. Energy Storage also enables users to collect energy, usually at low demand for lower costs, and use the energy when they need it. This could be at energy distribution networks, balancing the grid when needed, large energy consumption sites like retail stores, an emergency power source for companies and homes, or mobile energy consumption like electric vehicle (EV) batteries.
Increased power consumption in EVs, electrified appliances, the internet of things, and massive data collection and processing, makes providing a consistent and reliable energy source for these systems paramount.

Ruggedize Batteries to Withstand Environmental Exposure and Consumer Use
Energy storage applications and electric vehicle batteries operate in some of the world’s most demanding and extreme environments. To prolong safe and reliable battery performance at maximum efficiency, designs must be strategically ruggedized to protect against extreme heat, cold, UV exposure, wind, sand, rain, road vibration, and sudden impact.
Having an adequate seal for packs and modules protects the battery and its cells against liquid, gas, particle, and contaminant intrusion or exposure to prevent catastrophic failures and prolong battery life.
Sudden Impact Battery Protection and Compression Pads
Batteries need to be protected against sudden impact, vibration, and swelling forces that can come from mechanical movement, temperature cycling, sound, wind, or other environmental factors. Electric vehicle batteries experience additional extreme environments from harsh road conditions and collision impact from accidents and near-misses.
Boyd’s compression pads layer between battery cells to compensate for swelling forces, manage cell expansion and contraction of cell tolerance stack, and act as an impact protection barrier from mechanical movement resulting from collisions and vibration. Ruggedized impact-absorbing battery seals help you minimize the detrimental impact to batteries and reduce maintenance demand and consumer warranty costs while enhancing battery safety.
Battery Cooling and Isolate Battery Fire Risk to Maximize Efficiency and Safety
Batteries are the most integral part of an electric vehicle or energy storage installation with charge cycling, storage capacity, and range being a primary concern to adoption. Thermal density limitations are often a key contributing factor to innovation in this space. Boyd’s liquid cooling systems and cold plates enable smaller, lighter battery thermal systems; creating more design space for more powerful batteries with faster charge cycles and more efficient utilization of energy. Electric vehicles specifically benefit from EV batteries that are more reliable and have greater driving range per charge.
Battery Fire Isolation and Protection
Modern battery design is optimized to prevent fire from ever occurring. But in the rare event of a catastrophic battery failure with fire, proactive safety design integrates high performance and reliable fire isolation. Fire isolation can be achieved many different ways and at different battery system levels for primary and secondary fire isolation performance. Battery cells and modules can be wrapped with electrically isolating high performance films. These lightweight, rugged insulation layers wrap battery cells to prevent spart voltage between internal critical components that can lead to device shorting or fire. Using the highest flame-rated FR V0 isolation films helps to prevent fire from occurring, or isolating it at the primary battery cell level in the unlikely event a cell combusts.
SOLIMIDE® Battery Insulation and Protection
SOLIMIDE® is a fire resistant, ultra-lightweight, non-toxic foam that can maintain peak performance at both high and low temperature extremes. It is exceptionally flame resistant and used as a flame barrier in many critical applications. SOLIMIDE® will not ignite or combust under continuous long term direct exposure to flame, emits zero toxins and very little smoke. It offers traditional foam performance characteristics like compressibility and vibration damping. It’s also non-wicking with high hydrolytic stability, meaning it won’t retain water or water weight and can withstand long exposure to liquids. When applied in a battery pack, it acts as secondary fire protection at the battery pack level, isolating flame and fire while absorbing both mechanical vibration and acoustics for safer, quieter, more reliable batteries.
Preventing Li-ion Battery Thermal Runaway
Good temperature management of lithium-ion battery cells with additional back up safety features help to prevent battery thermal runaway events or respond safely and swiftly if they occur. Thermal runaway prevention starts with optimized design but also requires components that protect against thermal runaway propagation. Multi-functional, complex battery component solutions designed for cell-to-cell application absorb impact, vibration and movement, dissipate cell heat, and act a flame or heat barrier and isolator if a catastrophic event were to occur. Enable your designs to proactively and safely prevent thermal runaway events by managing vibration, movement and friction, and quickly isolate extreme heat or fire in the unlikely event battery safety design features fail to prevent cell-to-cell propagation. Highly integrated thermal runaway prevention assemblies feature cooling fins or heat spreaders with compression pads and flame-rated electrical insulation to isolate li-ion battery cells. Prevent, protect, and isolate battery storage thermal runaway and EV battery thermal runaway.
