In 2007, assistant professor Yi Cui and colleagues at the Department of Stanford University Materials Science and Engineering found that using silicon nanowires as anode rechargeable batteries increases the volumetric density of the anode up to a factor of 10. This is important because it offers the opportunity to use new types of active components for batteries.

The active components in a secondary cell are the chemicals that make up the positive and negative active material, and the electrolyte. The positive and negative are composed of different materials, thus presenting a positive reduction potential and has a negative oxidation potential. The sum respectively. Rechargeable batteries the positive electrode is the cathode and the anode discharge cargo, and vice versa for the negative electrode.

Already several alternatives rechargeable batteries to existing or developing. For transport, the uninterruptible power supply systems and laboratories, energy storage systems flywheel to store energy in a rotor that rotates the conversion to electric power when needed, these systems can be used to provide pulses of high power that would otherwise be objectionable in a common grid. For use as portable radios, flashlights, rechargeable batteries can be replaced by mechanisms watch or dynamos who crank by the user to provide power.

A future development could be ultracapacitors for transportation, using a capacitor large to store energy instead of the rechargeable battery banks used in hybrid vehicles. One drawback of capacitors compared with batteries is that the terminal voltage decreases to a capacitor that has 25% of its initial energy left in the half to take the strain initial. However, there are potential benefits in cycle efficiency, life, and weight compared to rechargeable battery system.
