That is an extraordinary finding, and it prompts the question of whether previously unsuspected battery materials might be lurking at the heavier end of the periodic table.
The scientists turned lithium-ion battery materials, such as copper, into a sprayable liquid form, which can be applied to any surface and turn it into an energy storage device.
FORBES: Soon We Might Spray-Paint Batteries Onto Any Surface
The warranty on the previous-generation LEAF's battery covered it against defective materials or workmanship for five years.

It sets a new standard for thinness in LTE devices, uses leading-edge display technology, resists flexing, glass breakage and water damage, has a striking design and thoughtfully selected materials, stretches battery life, matches with a bevy of optimized accessories, and enables remote file and media access via Motocast software .
It uses similar materials to create a battery that lasts longer and produces energy more efficiently.
The bigger the difference in the electropositivity and electronegativity of the materials that make up a battery's electrodes, the bigger the voltage it can deliver.
Battery efficiency, lifespan and even safety could be vastly improved, the researchers believe, by increasing the surface area of the active materials that make up the battery electrodes.
But start with this underlying fact: the cost of the raw materials alone necessary to make the battery is higher than the cost of gasoline.
All three Android-powered smartphones are built with top-of-the-line materials, are small in size, big on battery life and packed to the gills with the best experiences Google has to offer.
Select S Series models sport a premium and elegant design in Black or White with magnesium and aluminum materials, and all of them incorporate a built-in lithium polymer battery that when coupled with the all new and advanced large-capacity optional sheet battery, you can stay mobile and unplugged for up to 15 hours.

Many companies are working on coming up with better materials for the cathode or the anode in order to increase the energy density of the battery cell.
FORBES: Tin: The Secret To Improving Lithium-Ion Battery Life
The trick is to replace graphite with tin for the anode, which is one of the two main components in a battery cell, said Grant Norton, who headed the research and is a professor of mechanical and materials engineering at the university.
