Why Lithium-Ion Battery Storage Matters

Lithium-ion (Li-ion) batteries are now an essential part of everyday life in the UK. From mobile phones, laptops, and e-scooters to electric vehicles (EVs), cordless tools, and R&D applications, they power much of the technology we rely on.

Their popularity comes from being:

  • Lightweight compared to alternative energy storage solutions
  • Rechargeable with a long shelf life
  • Compact and versatile, making them ideal for a wide range of industries

But alongside their benefits, lithium-ion batteries also carry serious safety risks, particularly when stored in bulk. In commercial, industrial, and research environments, the potential for thermal runaway, toxic smoke, explosion, and fire makes compliant storage solutions absolutely vital.

The Hazards of Lithium-Ion Batteries

When stored or handled improperly, lithium-ion batteries pose several hazards:

  • Fire risk – damaged, overcharged, or overheated cells can ignite.
  • Toxic smoke – once ignited, they release gases that are difficult to extinguish.
  • Contaminated waste – firefighting materials become hazardous waste requiring specialist disposal.
  • Structural damage – without containment, fires can spread rapidly to equipment, facilities, and stock.

Definition: A “battery pack” is made up of multiple individual cells connected together electrically.

These risks mean that safe, fire-resistant, and monitored storage is no longer optional — it is essential.

Lithium-Ion Battery Storage Regulations in the UK

Unlike some energy sectors, there is currently no single piece of UK legislation dedicated exclusively to lithium-ion battery storage. However, businesses storing batteries in significant volumes must comply with multiple safety and environmental frameworks, including:

  • Health & Safety Executive (HSE) guidance on the safe use of batteries (both lithium-ion and lead acid)
  • Hazardous Substances Regulations (COSHH) for handling and containing toxic by-products
  • Environmental Agency requirements for the disposal of contaminated firefighting materials
  • UK Fire Safety Standards, especially for facilities holding bulk quantities of lithium-ion cells and packs

Because lithium-ion battery storage is an emerging field, regulations are still evolving. This makes it even more important for UK businesses in manufacturing, automotive, logistics, and R&D to adopt best-practice solutions that not only meet but exceed current compliance standards.

Best Practice for Safe Lithium-Ion Battery Storage

To minimise risk, businesses storing lithium-ion batteries in the UK should follow these guidelines:

  • Prevent physical damage – avoid dropping, crushing, or puncturing cells.
  • Maintain temperature control – store in environments with stable, regulated temperatures.
  • Prevent overcharging – use monitored charging systems to reduce the risk of short circuits.
  • Isolate damaged batteries – never store or reuse compromised cells.
  • Use fire-resistant storage units – engineered specifically to contain heat, flames, and gases.

By combining these precautions with a specialist battery storage container, businesses can significantly reduce the risk of fire, contamination, and regulatory breaches.

Fire-Resistant Lithium-Ion Battery Storage Units

At S Jones Containers, we have designed and manufactured a specialist range of bespoke fire-resistant storage containers tailored for lithium-ion batteries. These units are engineered for industries where safe, compliant storage is non-negotiable.

Key Features of Our Battery Storage Units:

  • Fire resistance – built to withstand extreme temperatures while retaining structural integrity
  • Environmental monitoring systems – track abnormal temperature, smoke, or gas levels
  • Alarm systems – provide early warnings before failures become critical
  • Custom design – each unit is CAD-designed to meet your exact specifications
  • Durability and compliance – engineered for long-term, regulation-ready storage

Unlike UPS or energy storage systems, our containers are purpose-built for safe static storage of lithium-ion batteries, making them an ideal solution for R&D labs, EV manufacturers, and industrial facilities across the UK.

FAQs: Lithium-Ion Battery Storage in the UK

Are standard shipping containers suitable for lithium-ion battery storage? 

No. Standard containers must be modified with fire-resistant materials, ventilation, and monitoring systems to be safe and compliant.

Do I need a licence to store lithium-ion batteries? 

Not specifically, but UK businesses must comply with fire safety, COSHH, and HSE guidelines.

Do regulations apply to both cells and battery packs? 

Yes. Whether storing individual cells or complete packs, the same safety principles and regulatory considerations apply.

How many batteries can I store in one unit? 

Capacity depends on battery type, risk assessment, and fire safety requirements. Our team can advise on the right configuration.
