A fuel cell is a battery that converts the chemical energy of a fuel into electrical energy through the chemical reaction of the fuel. The advantage is that the energy conversion efficiency is high and the process of charging is not needed. By adding fuel, it can maintain long-term use.
Previously, foreign media also broke the news that Apple has been granted a patent for a layered battery system technology. This technology can achieve more efficient lithium battery applications, and has improved battery life and charging speed. Because the technology of lamellar battery technology has been developed for 10 years. For years, so the industry generally believe that this technology will usher in an outbreak this year.
However, the development of the battery technology to commercialization has a long way to go. It is unclear how the iPhone will solve the battery problem in the future.
