Researchers at Rice University have just announced a prototype lithium-based rechargeable battery that has three times the capacity of current lithium-ion batteries. This technology is expected to become a new development for lithium metal batteries (no success precedent in the industry). In particular, this technology solves the problem of "dendrites" (also caused by lithium deposition) that seriously affect the battery life and even cause explosion and short-circuit fires ). James Tour, a Rice University chemist, and his colleagues have come up with a solution to the problem - a "unique anode" made of carbon and graphene nanotubes.
These hybrid nanotubes will replace the graphite anodes previously used on commercial lithium-ion batteries.
In a recent statement, it said using the new technology and a lithium-metal battery coated with a layer of carbon would prevent dendrites from spreading extensively on the anode (which could eventually lead to a substantial reduction in shorts).
The article said that the lithium prototype battery can store 3351 mAh per gram of energy, compared with the current technology has made great progress. Consumer electronics such as smartphones and tablets will benefit the most, with longer battery life and charging rates.
Of course, Rice University is not the first institution to make progress in lithium-ion battery research recently.
US Naval Research Laboratory has just ushered in a milestone in the development of zinc-based batteries, the more secure than lithium-ion batteries, but still not practical enough on the issue of charging.
By developing a 3D "sponge" electrode, researchers are expected to circumvent this problem, creating a battery that is both affordable, safe, and rechargeable at the same time.
A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque. Geared devices can change the speed, torque, and direction of a power source. Gears almost always produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a simple machine.
