An earth battery is a pair of electrodes made of two dissimilar metals, such as iron and copper, which are buried in the soil or immersed in the sea. Earth batteries act as water-activated batteries .
Lithium-ion batteries must be handled with extreme care from when they're created, to being transported, to being recycled. Recycling is extremely vital to limiting the environmental impacts of lithium-ion batteries. By recycling the batteries, emissions and energy consumption can be reduced as less lithium would need to be mined and processed ...
The new technology would allow for solid state batteries that are not only more efficient than today’s batteries, but more environmentally friendly and safe, too. Scientists are making ‘super ...
An encapsulated thermal battery is physically similar to a phase change thermal battery in that it is a confined amount of physical material which is thermally heated or cooled to store or extract energy. However, in a non-phase change encapsulated thermal battery, the temperature of the substance is changed without inducing a phase change.

This battery type is specifically designed to pollute less (see environmentally friendly claims) due to the lesser use or the absence of heavy metals. Water-activated batteries have been used in radiosondes that shouldn't contain heavy metals since they regularly fall to the ground or ocean surface, and indefinitely remain there.
Aluminium–air batteries are better for the environment compared to traditional lithium-ion batteries. Aluminium is the most abundant metal in the Earth's crust, so mines would not have to be as invasive to find a similar amount of aluminium compared to lithium.
