Charging sustainability: plant-based dual carbon batteries

TechX Pioneer Spotlight: PJP Eye

The continued production of batteries from rare metals may be at risk due to the forecast resource depletion of metals such as cobalt and lithium, as well as the environmental impact associated with the mining and processing of these metals. Only 5% of lithium-ion batteries are recycled today, with most of them ending up in landfills, causing pollution in our oceans and soils.

PJP Eye is currently developing an alternative, revolutionary solution; rechargeable plant-based dual carbon batteries that utilise industrial waste instead of rare metals, while boosting performance. Produced using organic cotton and agricultural waste, the batteries are non-explosive, can be charged 10 times faster than those made with commercial lithium and are high voltage. With potential applications in the maritime, aviation and automotive industries, the batteries also offer an extended life of more than 20 years resulting in less waste and reduced demand for new batteries.

After a decade of joint research with Kyushu University in Japan, PJP Eye aims to mass-produce these by 2025 and install them in a variety of electric vehicles, including ships and airplanes.

Established in 2017, the team of six share a commitment to tackle the climate crisis by collaborating with companies in the energy industry, accelerating decarbonisation and helping to secure a more sustainable world for future generations. After conducting a comprehensive lifecycle analysis, the company found that for every 1 megawatt of storage, its batteries emit 1 tonne of CO₂ while conventional lithium-ion batteries emit 30 tonnes, when compared across a 15-year timeframe. This represents a 97% saving in CO2 emissions.

“PJP Eye is delighted to be part of TechX cohort 4, giving us a unique opportunity and advantage to attract more investors, manufacturing partners and potential customers, which will ultimately help us introduce our batteries to UK markets.

“We want to offer our solution to the companies making a difference, including those in the energy sector helping drive the transition to net zero. Our ultimate goal is to solve global environmental, social and economic problems while helping deliver essential services.”
