What is the usb power pack supply circuit board schematics

Posted Jan 12 2013 6:22am

Mobile power supply circuit board manufacturer tells you principle:

Usb power pack protection board circuit, mainly by the discharge overcurrent protection module, discharge overcurrent protection module, short circuit protection module, overcharge protection module, over-discharge protection module. The shell is aluminum.

Mobile Power, also known as mobile phone back-up power, iphone backup mobile power, plug-in mobile power, leather case mobile power, universal mobile power, protective shell mobile power.


Manufacturer of mobile power battery charger you about the lithium-ion battery electrolyte materials can be divided into what?
 Lithium-ion batteries can be divided into a liquid lithium-ion battery (Li-ion Battery) and polymer lithium-ion battery (Polymer Lithium-ion Battery, referred to as Polymer) two categories. Positive and negative materials with liquid lithium ion polymer lithium ion batteries used are the same, the cathode material can be divided into lithium cobalt oxide, lithium manganese oxide, ternary materials, and lithium iron phosphate material, is extremely negative graphite, the battery works also consistent.
 The main difference lies in the different electrolytes, liquid lithium ion battery using a liquid electrolyte, and lithium ion polymer batteries by the solid polymer electrolyte instead of such polymers can be "dry", and may be colloidal, phone mobile power using a polymer gel electrolyte.
