ScienceDaily reports:
Present-day lithium batteries are efficient but involve a range of resource and environmental problems. Using materials from alfalfa (lucerne seed) and pine resin and a clever recycling strategy, Uppsala researchers have now come up with a highly interesting alternative. Their study will be presented soon in the scientific journal ChemSusChem.
Although present-day batteries contain non-renewable inorganic materials, this is not the first time batteries composed of renewable materials have been presented. But the recycling and recovery strategy is a wholly new concept. Constructing a new battery from a spent one is also feasible. In other words, a straightforward process enables it to be reused.
The scientists have shown that the lithium extracted from a spent battery can be used for a new battery: all that needs to be added is more biomaterial. Their battery proved capable of delivering as much as 99% of the energy output from the first. With future modifications, this figure can very probably become even higher, say the researchers.
