At present, we are in a society that advocates sustainable development, and it requires that we do not compromise the opportunities for future generations to develop and find the resources to meet today's challenges. Obviously, if you can invent an environmentally friendly battery, you can make a great contribution to this cause.
We already have countless kinds of batteries--from tiny, less than 1g-heavy hearing-aid batteries to more than 1T-heavy emergency power supply batteries. In addition, the battery is divided into two, the use of the toss, or repeatedly charging two.
Lithium's atomic number is 3, the lightest metal, and is widely used to make lithium-ion rechargeable batteries, which are ubiquitous in mobile phones, laptops and even electric vehicles. Compared to the old Ni-CD batteries or lead-acid batteries, lithium battery has made great progress, but still in the form of metal oxides, environmentally friendly this piece is not enough.
The exploitation of lithium resources, involving rocks, clay, brine and other minerals, requires a large amount of energy, while causing great damage and pollution to the local environment. In addition, lithium batteries are not currently recoverable in a cost-effective manner.
Conductive Redox polymer
Christoffer Karlsson, a doctoral student at Uppsala University in Sweden, has shown his research findings in his doctoral dissertation. That is, one by one of new types of organic materials-conductive redox polymers, a class of conductive plastic-to solve the inherent defects of the battery today.
Karlsson defended his research and released a press release at Uppsala University, saying the plastic has huge potential for development and is the future of batteries.
Obvious advantages
Conductive polymers have many unique properties, which lead to their wide and different forms. Conductive polymers not only have the electrical conductivity of metal, but also plastic plasticity, which is a major advantage. In addition, "forging" such materials do not require high temperature, so the cost is very low, this is also a big attraction.
The Swedish doctor believes that in an environmentally friendly manner, the use of renewable resources to build new batteries, and today's use of inorganic materials battery is a difference. "They have potential as electrode materials for future environmentally friendly batteries, and are more likely to make pure organic cells from polymers." Christoffer Karlsson said.
