New lithium-ion battery: convert movement into energy

According to media reports, researchers at the Georgia Institute of Technology has developed a new lithium-ion battery, when the battery is compression or bending it can recharge it self through some chemical changes.

The researchers abandoned accommodating the battery electrolyte (a gel substance, stored energy through chemically) of the plastic container, Replaced by a layer of piezoelectric nanotubes (it can converted the motion into energy), and develop this kind of hybrid battery that can converted the motion into electrical energy and chemical energy.

Under normal circumstances, the piezoelectric device will convert the kinetic energy into electrical energy, and then convert it into the chemical energy through the charging circuit in the standard lithium-ion battery. But this kind of new hybrid battery can be directly affected by its own internal ion flow, Therefore, the researchers can completely skip the charging circuit, to capture the mechanical energy with a more efficient way, Although this relates to the physical movement, but the size is very small, the less obtrusive biomechanical devices can provide an effective solution to help solve the growing energy demand of the mobile device.
