Japan – Automaker Nissan and their affiliate 4R Energy Corporation have unveiled Reborn Light, a sustainable street light utilising reused lithium-ion batteries taken from their range of electric vehicles (EVs).
Once the storage capacity of lithium-ion batteries falls below a certain level, they’re no longer able to serve their purpose in EVs. Nissan's initiative illustrates how these can be repurposed to create new forms of infrastructure, independent from the energy grid. Solar panels mounted at the top of the LED-powered lights absorb energy during the day to charge the battery for use after dark.
The Reborn Light is being targeted at communities who don't have access to mains electricity or have been decimated by natural disaster. 'Seventeen percent of the world’s population live without electricity,' the brand said in a statement. 'Reused EV battery and lighting have the potential to change the lives of people in Japan and the world.' The automaker plans to install the light in Namie, Japan, a town devastated by the 2011 Tohoku tsunami.
Mobility brands like Nissan are exploring how battery technology can be used to create new energy networks that are more efficient and flexible than their forebears.
