Scientists develop new lithium batteries: bendable, low cost, safer

Chinese scientists have recently developed a lithium battery that is resistant to burning and explosion. It is reported that lithium batteries made from new materials can be bent, low cost and safer. Currently, the technology has been published in the latest issue of the American Chemical Society's Nano Express.

Replace traditional liquid electrolyte

The new technology was developed by the team of materials scientist Xinyong Tao of Zhejiang University of Technology. They replaced the traditional liquid electrolyte with a solid electrolyte mixed with magnesium borate. Xinyong Tao said that inorganic magnesium borate can improve the ionic conductivity and mechanical properties of the electrolyte. The flexibility can be maintained, and the stress caused by the volume change of the buffer electrode material during charging and discharging is obtained, and a stable electrode interface is obtained.

Liquid electrolyte battery mobile phone has burning and explosion hazards

Magnesium borate is also a non-polluting, low-toxic flame retardant that increases the stability of the fire-resistant carbon layer. Conventional liquid electrolytes are usually composed of lithium hexafluorophosphate and flammable and explosive ethylene carbonate and dimethyl carbonate. Energy storage devices such as mobile phones and automobiles using liquid electrolytes have safety hazards of combustion and explosion.

According to previous news, researchers at the University of Maryland have made major breakthroughs in a new water and zinc-based battery, or will be used in consumer products such as mobile computers in the future. The battery has the characteristics of safety, large power and long life, and its safety is greatly improved, and the lithium ion battery is also surpassed in terms of power density and life.

With the rapid development of digital products such as mobile computers, the battery industry does not seem to have much change, but this year it is frequently exposed by battery technology, and we hope that they will be used in our digital products as soon as possible.
