Chemstore supplies bespoke Electrovault lithium-ion battery storage units for businesses across the UK. Units can be manufactured to suit different battery quantities, charging arrangements and site requirements, with options including temperature and humidity control, gas detection, fire suppression, remote monitoring, restricted access and segregated quarantine areas. Electrovault systems are designed to support safer battery storage, charging and handling in line with relevant fire-safety guidance.
Our Electrovault storage units are designed with reference to RC61 recommendations for lithium-ion battery storage and can be tailored to suit your specifications. Units are fully customisable and can be manufactured in a wide range of sizes to suit individual site requirements.
Optional extras include:
Lithium-ion batteries are now used extensively across industry, but major safety concerns surround battery storage, quarantine procedures, the transport and disposal of damaged batteries, and thermal runaway.
During thermal runaway, the high heat created by a failing cell can affect neighbouring cells, causing them to also become thermally unstable. A battery pack can be destroyed within minutes or an incident can continue for hours as individual cells enter thermal runaway. An irreversible thermal event in a lithium-ion battery can be initiated in several ways, including an internal or external short circuit, overcharging, external heating, fire or mechanical abuse.
During thermal runaway, gases including hydrogen fluoride (HF), phosphorus pentafluoride (PF5) and phosphoryl fluoride (POF3) may be released. Studies have also examined the potential formation of HF during fire suppression involving water.
Chemstore designs and supplies lithium-ion battery storage solutions for commercial and industrial sites across the UK.
Our approach begins with the risks, operational requirements and layout of your site. From there, we can develop an Electrovault solution designed around the batteries being stored, charging requirements, access, handling processes and the safety controls required for the project.
The aim is to provide a practical storage solution that helps businesses improve battery safety, reduce operational risk and minimise disruption where lithium-ion batteries are stored or charged.
Chemstore provides a full design service from the initial project requirements through to manufacture and delivery.
Our team can work with your required dimensions, battery capacity, handling processes and site constraints to develop a configuration suitable for the intended application.
Electrovault units are manufactured to Chemstore’s in-house quality requirements, with project scheduling and delivery planned around the agreed programme.
Yes. Electrovault units can be manufactured around site-specific dimensions, battery capacities, access requirements, handling processes and safety controls. The standard pallet configurations provide a starting point, but larger and bespoke installations are also available.
The small Electrovault range is an engineered lithium-ion battery storage unit designed for sites requiring compact, compliant hazardous material containment. Suitable for workshops, factories, and warehouses, it provides secure external battery storage with integrated bunding, controlled ventilation, and options for fire detection and suppression to mitigate thermal runaway risk. Available in both standard and walk-in configurations, every Electrovault can be fully bespoke and manufactured to a client’s specific operational, spatial, and safety requirements.
