Each year battery technology improves right alongside of computing hardware, processing speed, memory capacity, sensors and other electronic advancements. If you recall Moore’s law, "The number of transistors incorporated in a chip will approximately double every 24 months." This can hold true for battery technology as well, and has opened new doors to higher capacity, longer lasting, and quicker recharging batteries.
Virus-powered batteries are being developed by a team of MIT researchers using lithium-ion battery technology with a harmless virus called M13. The M13 virus is a bacteriophage that creates a lightweight and multi-purpose battery that can be made in any shape or size. This allows the virus powering rechargeable batteries to be woven into closed and used for portable devices, such as iPods, GPS, radios, cell phones and other small devices. The U.S. military is interested in testing this technology on a larger scale with UAV drones.
Rechargeable batteries through kinetic energy are also on the horizon for future batteries. Just simply shake your device to keep it playing your favorite song, track your GPS location, or carry endless amounts of cell phone power. Nokia Corporation has recently filed a patent for the use of a battery using kinetic energy to power a device, which was called the “Piezoelectric Kinetic Energy Harvester.” Kinetic energy powered cell phones definitely look like a possibility for Nokia in the near future.
Swappable batteries are nothing new for electronic device technology. We do this with our cell phones, digital cameras, and radios when we run out of juice and need a full charge immediately. However, we have not seen Electric Vehicles (EVs) with swappable batteries readily available. With the growing amounts of EVs on the road, you can expect to see longer lasting batteries giving further range for electric cars. Many EVs have limited range, but a universal battery pack could resolve this issue by supplying fully charged battery packs that can be swapped at fuel stations across the country.
As technology keeps advancing, so will battery technology. Keep up to date with rechargeable batteries and recycle your used batteries to keep the green trend growing with renewable energy and minimizing your carbon footprint.
