Do more today with the combined power of sustainability & performance
“LITHIUM-ION battery storage goes hand-in-hand with renewable energy, but these batteries are extremely difficult to repurpose or recycle, creating a huge waste problem.” Dr Amrit Chandan highlights the challenges of the industry and the benefits of the Aceleron technology.

The article by Amanda Doyle titled “Powering the future: the lithium battery that doesn’t get thrown away” is an interview with Aceleron’s CEO Dr Amrit Chandan that discusses the industry challenges, the triggers for our founders to “leave their jobs” and set up Aceleron and the benefits of our technology.
Aceleron has developed a compression-based approach to assembling the batteries, using fasteners to connect the parts and complete the circuit. “It’s almost like a sandwich,” said Chandan. “We have a bottom tray with embedded electronics and connecting parts, we have our cells, and we have the reverse of the bottom tray.”
This makes the batteries easy to disassemble and to replace parts when needed. The design also had the unexpected but welcome result of making the batteries safer. Typically, if one cell in a battery starts to overheat, the whole pack can ignite or explode due to the close proximity of the cells and the amount of energy being compressed into a small volume. “We’re spacing cells apart a bit more but also we have protection on every single cell and also if a single cell does experience some kind of failure then the compression usually gives out first, which breaks the circuit and it helps to calm the situation down. We didn’t realise that at the start.”
Aceleron’s technical team offer some helpful tips on the best way to store a leisure battery in order to maximise its life expectancy and guarantee peak performance for years to come.
Aceleron, which has designed and built the only battery energy storage system (BESS) that can be taken apart for repair, replacement and upgrade, has partnered with Nuenta, one of the largest distributors of renewable and environmental supplies in the UK.
Aceleron’s uniquely serviceable, repairable and upgradeable LFP battery, the Essential has been recognised for its environmental design by the international DAME design awards committee, which celebrates everything that is important about marine equipment design.
