Cause1. Internal polarization is large;2. A polar slice absorbs water, reacts with the electrolyte;3. The quality and performance of the electrolyte itself;4. The amount of injection in injection does
SafeguardAfter the lithium battery core is charged to the voltage higher than 4.2V, side effects will begin. The higher the voltage, the higher the risk. After the lithium battery voltage is higher th
Carbon negative materialThe negative materials actually used in lithium ion batteries are basically carbon materials, such as artificial graphite, natural graphite, middle phase carbon micro -ball, pe
In 1970, the M.S.Whittingham of Daikeson used titanium titanium sulfide as a positive electrode material and metal lithium as a negative electrode material to make the first lithium battery.In 1980, J
The earliest lithium battery was applied to the pacemaker in the early stage. The self -discharge rate of lithium batteries is extremely low, and the discharge voltage is gentle, so that the pacemaker
