So why is battery technology still underwhelming? Plenty of companies have been developing smarter battery technology for years, including methods to increase battery capacity tenfold or charge devices by pulling energy from the air. But lithium ion, the technology that most mainstream batteries are based on, is low cost and easily reproducible while being safe — so we’ll be stuck with it for the foreseeable future, said Charlie Quong, an executive at Mophie, a battery accessory maker, in an interview.
电池技术的发展为何仍然普通？很多公司都已多年开发智能电池技术，包括将电池容量增加十倍的方法，或者从空气中吸取能量的充电设备等。但是目前主流的电池都是锂电池，它成本较低、容易降解，而且安全，所以我们在可预测的未来还将使用它，电池配件制造商Mophie公司的一位高管查理·奎昂(Charlie Quong)在接受采访时说。
“There’s a lot of investments on all fronts for improving the technology above and beyond that, but I don’t think we’re going to see that hitting any kind of mass market for several years out,” Mr. Quong said. In general, lithium ion improves about 10 percent a year in terms of the amount of energy that can be stored in a given space, which is partly why consumers perceive batteries as being far behind other technologies.
“在电池技术前沿已经有过不少投资，但我认为，新技术几年内不会大规模投放市场，”奎昂说。总的来说，锂电池技术的进步保持在一年可以增加10%的固定空间蓄电量水平，所以消费者觉得电池技术的进步远比其他技术进步要慢。
