The battery can also be soft

LG Chem is one of the world's largest chemical companies and is owned by the Korean treasury LG Group. They have recently broken the original rigid rectangular image of lithium batteries and developed a linear lithium battery with a wire that is generally linear and bendable. The linear lithium battery has a texture similar to that of a wire, and can be knotted and entangled. If there is a leisurely feeling, it can be knitted into various patterns.

Regarding the chemical principle, the linear lithium battery is no different from the ordinary lithium battery used in the notebook of our mobile phone. An anode, a cathode made of lithium cobalt oxide (LCO), of course, electrolytes. Unlike a normal lithium battery, a linear lithium battery does not use a layered structure to construct a battery, and it adopts a hollow spiral structure.

LG Gold uses copper wire coated with nickel-tin alloy as the anode of a linear lithium battery. The copper wire was densely wound around a 1.5-mm-diameter stick in a circle and a circle. After the winding was completed, the stick as a core was taken away, and the remaining copper wire became a spring-like hollow spiral structure. The next work is to wrap the hollow spiral structure with an insulation layer and then wrap the aluminum wire around it. Finally, LG used the suspension of lithium cobalt oxide to coat the entire line, and the cathode of the battery was completed. As long as the insulated outer skin is placed, the electrolyte is poured into the hollow of the spiral structure, and the linear lithium battery is completed.

The linear lithium battery is definitely an epoch-making product. Previous studies on "soft batteries (also called soft batteries)" have had certain results, but because of the use of "secondary products" such as high molecular polymers, energy density is very low, and the softness is seriously insufficient (just like plastic). The performance of a linear lithium battery is exactly the same as that of a normal lithium battery, but it has the same physical characteristics as a wire, and the advantages are not to be said. As for battery life, this is of course related to length. According to LG's test, a 25 cm long linear lithium battery can power the iPod Shuffle for 10 hours. LG said that it hopes that the linear lithium battery can be popularized in popular equipment in 2017.

People have always ignored the importance of batteries in the development of computers. Intel can make transistors that are only a few atoms in size, and it can produce processors that are only a few watts in power, but can handle billions of tasks per second, while the battery we use is always the big one, you even can't change the shape. The backwardness of the battery limits the innovation and development of the computer industry. If the linear battery can help humans break through the original imprisonment, the electronic products in our hands will have to be changed. The notebook can abandon the round battery, and the phone and tablet can also be liberated from the battery board. We can plug the battery into the extra space inside the device, and even convert the battery into a decoration or a casing. The volume of the device will be greatly reduced, and the weight of the device will be greatly optimized. We can also make battery bracelets and battery necklaces to charge anywhere. Combined with the development of soft displays, we can even make soft phones and computers, and the IT world will be different.
