"Big screen, quad-core, ultra-thin, etc." has become the standard for flagship mobile phones, which also puts high demands on battery design. Now even if the mobile phone "does not eat or move" for a long time, the power is often greatly reduced. If the mess is toss, the battery can guarantee half a day is a blessing. No wonder a friend said that the current smartphone "does work like a horse and consumes electricity like a tiger."
Samsung's next-generation A15 dual-core processor is still only the best example on the Chrome Book - high performance but power consumption is also obvious! So let's take a look at the battery technology for these high-performance mobile phones.
Polymer lithium battery, blade mobile phone must
The main difference between a polymer lithium ion battery and a conventional liquid lithium ion battery is the difference in electrolyte. Lithium-ion batteries use liquid electrolytes, while polymer lithium-ion batteries are replaced by solid polymer electrolytes, which can be either "dry" or "colloidal", which just makes up for the tradition. The shortcomings of lithium batteries.
I believe many of my friends have seen the appearance of traditional mobile phone batteries: except for packaging, it is the whole body "armor" - due to the use of liquid electrolyte, traditional lithium batteries must be sealed with metal containers such as "iron cans", so the ultra-thin design and Shape design is limited. Lithium polymer battery has a certain plasticity like plasticine because of its gelatinous shape. It can be changed according to the internal space of the mobile phone. It is easy to reduce the thickness of the mobile phone battery to 2~4mm, which is about The thickness of the business card is a little thicker, so there is a mobile phone that is now as thin as a knife.
Solar LED land lamp uses sunlight as the energy source, charges during the day and uses at night, does not need complex and expensive pipeline laying, can arbitrarily adjust the layout of lamps and lanterns, safe and energy-saving, pollution-free, stable and reliable without manual operation, saving electricity and maintenance. Solar LED street lamp is mainly composed of solar cell module (including bracket), LED lamp holder, control box (with controller, battery) and lamp pole.
