元器件交易网讯 2月18日消息，据外媒报道，韩国蔚山国家科学技术研究所（UNIST）教授将开发一款可打印电池，用于谷歌眼镜，预计五年内实现量产。

韩国科学家已经研发出世界上首款可弯曲锂电池，这款电池即使弯曲或卷起来也不会爆炸。开发者称，这款电池由韩国蔚山国家科学技术研究所（UNIST）和LG化学共同研发，从现在开始的三年内可以量产。

UNIST教授Lee Sang-young称，“这款电池一旦商业化，任何电子产品或设备都可以弯曲。”

Lee算是“电池专家”，他对未来设备有宏伟的计划，包括为谷歌提供可伸展电池。

李说，直到现在可弯曲的电池尚不存在。即使是那些已经被三星和LG开发的也不是真正的弯曲。

电池拉了可穿戴设备的后腿，它们占据设备的大部分空间，技术发展的脚步是最慢的。

“这主要是存在安全问题。”Lee说，“当电池不断弯曲或折叠，电池内部的分离器就会变热熔化，这就存在爆炸的危险。”

研究人员尝试用不易燃烧的聚合电解质代替分离器。

这个突破源自今年早些时候Lee的团队成功开发一个灵活、耐热塑料晶体电解质。教授说：“它比传统的聚合电解质薄10倍，可弯曲度高30倍。”

这个测试显示即使电池被折叠或卷起，它仍能正常工作，不会发热或爆炸。

Lee的工作成果今年1月份被写进德国科学期刊《先进功能材料》(Advanced Functional Materials)。

他下一步是开发可打印的电池，可以像果酱一样扩散到表面。它们是在电极两段传播诸如电解质流体之类的物资,然后暴露在紫外线下30秒。

他说：“例如，当电池扩散到衣物上，衣服边就成了供能源。”

他希望为谷歌眼镜提供这种电池，用这些可弯曲电池可使谷歌眼镜设计更增酷感。

一旦商业化，这些打印电池可以为电子产品和面料带来突破性的设计创新。

Lee的团队去年年初在最初的技术开发工作中取得成功，这项工作仍在继续中。他预计在五年内可以大规模生产，因为研究目前仍处于初级阶段。

orean researchers have developed the world"s first bendable lithium-ion battery that will not explode even when bent or rolled up. The batteries, which were jointly developed by Ulsan National Institute of Science and Technology and LG Chem, can be mass-produced as early as three years from now, the developers said.

“Any electronic gadget or appliance can become flexible once this battery is commercialized,” said Lee Sang-young, a professor at UNIST, in an interview with The Korea Herald.

Lee is something of a “battery specialist” who has great plans for the future of appliances, including supplying Google with spreadable batteries.

Lee said that until now, curved batteries had not existed. Even those that have been developed by Samsung and LG are not truly curved, Lee said.

Batteries have long been a drag for wearable devices. They take up the most space in the gadget, and the pace of their technology development has been the slowest.

“It is mostly due to safety issues,” Lee said. “When a battery is constantly bent or folded, a separator inside the battery gets hot and melts, which poses the risk of explosion.”

Research has long been carried out on replacing the separator with a nonflammable polyelectrolyte.

The breakthrough came for Lee earlier this year when his team succeeded in developing a flexible, heat-resistant plastic crystal electrolyte. “It is 10 times thinner and 30 times more flexible than the conventional polyelectrolyte,” the professor said.

Tests showed that even when the battery was badly crumpled or rolled up, it still worked without heating up or exploding.

Lee"s work was published in Germany"s scientific journal Advanced Functional Materials in January.

The professor"s next step is to develop printable batteries, which can be spread onto surfaces like jam. They are made by spreading the fluid-like electrolytes on electrodes, then exposing them to ultraviolet rays for 30 seconds.

“For instance, when the batteries are spread on fabrics, your clothes can be a source of power supply,” he said.

He hopes to supply them to Google Glass, saying that the flexible use of these batteries would make the glasses much cooler in design.

Once commercialized, these printable batteries can bring breakthrough design innovation to electronics and even to fabrics.

Lee"s team succeeded in the initial technology development early last year and is still working on it. He expected mass production to be possible in five years as research is still at an early stage.
