Electricity is undoubtedly one of the greatest discoveries of mankind. Nowadays human society cannot leave electrical energy. In the field of consumer electronics, any digital product also relies on batteries. At the same time, people also hope that battery life can be as long as possible, reducing the number of recharges per day and the length of each charge.

From nickel-metal hydride batteries to lithium batteries, lithium polymer batteries, although the life expectancy is not satisfactory, but have to look at another angle. For example, mobile phones can only receive and send SMS messages from the era of Big Brother to the functional machine era. Nowadays, mobile phones are multimedia Internet terminals. Digital products are upgrading, and battery and charging technology are constantly evolving. Let's take a look at the most promising new battery and charging technology.

Although lithium-ion batteries have been available for a long time, they have the characteristics of high popularity and low cost, so it is not realistic to completely replace them. However, manufacturers such as Toyota have begun to develop solid-state lithium-ion batteries, which are safer and faster than liquid lithium batteries. The solid-state battery developed by Toyota can be recharged within 7 minutes, and its large capacity is also very suitable for use in electric vehicles, significantly reducing the charging time.

In addition, the future of solid-state batteries also includes aluminum air batteries, sand batteries, etc. These technologies focus on environmental protection, low cost and outstanding performance, and may one day completely replace liquid lithium batteries.
