Despite their hefty price tag, smartphones have an average consumer lifetime of about three years. The lithium ion batteries that power them, however, can last for about five years—meaning that just about every discarded smartphone generates e-waste and squanders the battery’s twilight years. To cut down on the environmental waste and provide storage for rural communities, researchers at Kyung Hee University in Seoul have proposed a model for recycling unspent lithium ion batteries into energy storage units for solar-powered LED lamps.
