Did you ever think about why your phone works at all? Probably not. But, if you think about it, all portable gadgets rely on a battery to keep ticking – and some have better battery life than others. That’s why we’re going to take a peek at what keeps your phone ticking and why some batteries do better than others. On the basis of chemistry used for ions carrying electrolyte material, Lithium battery can be classified into Lithium ion and lithium Polymer. Lithium ion battery uses liquid lithium ion as electrolyte while lithium polymer use solid or gelatin like polymers as electrolyte. Lithium ion batteries have high energy density and cost less than lithium polymer. Lithium polymer batteries are light weight and have improved safety . However their cost is high (30% average) as compared to lithium ion. Also the the energy density of Li-Polymer battery compared to Li-Ion Batteries is quite less. Lithium ion batteries tend to lose charge with ageing even when not us

What is the material of lithium battery?

Strictly speaking, lithium batteries are divided into two types: lithium metal batteries and lithium ion batteries. This is defined in terms of the presence of lithium, which uses metal lithium as an electrode and a lithium ion battery in an ion form at the electrode. Lithium metal batteries generate electricity by corrosion or oxidation of metallic lithium. When used up, they are discarded and cannot be charged. Therefore, they are also called primary batteries. Lithium-ion batteries use the difference in concentration of lithium ions for energy storage and discharge. Metal lithium is not present in the battery, so it is also called lithium secondary battery. Currently used in mobile phones, cameras, power tools, electric vehicles, energy storage, communication base stations and other rechargeable lithium batteries, are lithium-ion batteries. Most commonly used lithium batteries in the market are lithium-ion batteries, and everyone is used to abbreviate as lithium
