What is the advantage of secondary lithium battery?

Source: 2020 - 03 - 23 15:08 hits: once the circuit is mainly composed of the lithium battery maintenance asic DW01, charge and discharge control MOSFET1 ( Including two n channel MOSFET) Parts, such as a single lithium-ion battery connection in B + and B - Between the battery output voltage by P + and P - Composition. When charging, the output voltage of the charger connected to the P + and P - Between the electric current from a single cell P + B + and B - , by charging control MOSFET to P - again 。 In the process of charging, when a battery voltage is more than 4. 35 v, output signal of the OC of asic DW01 charge control MOSFET is turned off, lead to the lithium battery to immediately stop charging, in order to prevent damage of due to excessive rechargeable lithium batteries. Discharge process, the monomer battery voltage of 2. 30 V, OD DW01 feet output signal to close the manipulation of the MOSFET discharge, lithium batteries immediately stop discharge, and prevent the damage of lithium battery due to the discharge, DW01 CS feet, output short circuit current, charge and discharge control field effect transistor, the pressure drop increases CS feet high voltage agile, DW01 output signal charge and discharge control fet closed flexible, and complete the maintenance of a current or short circuit. What is the advantage of secondary lithium battery? 1. High energy density. 2. High working voltage of 3. No recall of the effect of 4. Long cycle life. 5. 6 no pollution. Light weight 7. What is the advantage of low self-discharge lithium polymer batteries? 1. Leakage, no battery, battery does not contain liquid electrolyte, using colloidal solid; 2. Can be made into thin battery: volume 3. 6 v400mah, thickness can be thin to 0. 5mm; 3. The battery can be designed into various shapes; 4. Flexible battery deformation: flexible polymer battery maximum deformation of about 900; 5. It can be made into a single pressure: battery only get high pressure with liquid electrolyte by several cells in series. As there is no liquid polymer battery, so can be made into multi-layer composite, so as to achieve high pressure in a single battery. 6. Lithium ion battery capacity will be the same size. Lithium battery cycle life test: put battery at 0. 2 v to 3. 0 v/cell; 1. 1 c constant current constant voltage charging to 4. 2 v cut-off current 20 ma aside an hour, a zero discharge. 2 to 3 c. 0v( 1 cycle) ; After 500 times repeated cycle, capacity should be greater than 60% of the initial capacity; According to the provisions of the state, lithium battery charging standard test is ( IEC no rules) 。 Put battery in 3. 0/0. 2 c under voltage, constant current charging to 4. 2 v, the voltage of 1 c, cut-off current of 10 ma. 28 days at 20 + _5 temperatures, discharge capacity of 0. 2c ~ 2. 75v。
