Discover the Key Differences Between Lithium Polymer Batteries and Other Types!
UN li-polymer 🔋 (wiki) works like a liquid lithium battery. The big difference is the electrolyte (wiki). Instead of liquid, it uses a polymer. The battery has three main parts: a positive side, negative side and the electrolyte. In a lithium polymer battery, at least one of these parts is made from a polymer material.
Batterie au lithium ordinaire
Batteries Li-polymère ordinaires communément appelées “lithium”, currently have a relatively good overall performance of the battery system. Li-polymer battery negative electrode is a carbon material, such as graphite. The positive electrode is a transition metal oxide containing lithium, such as LiMn2O4.
Advantages of li-polymer batteries
- High operating voltage, li-polymer battery operating voltage at 3.6V. This is three times the working voltage of NiCd and NiMH batteries.
- High specific energy. The specific energy of li-polymer batteries has reached 140Wh/kg, which is 3 times of NiCd battery and 1.5 times of NiMH battery 🔋 . 1.5 times NiCd battery.
- Long cycle life. At present, the cycle life of li-polymer batteries has reached more than 1000 times, and in the low depth of discharge can reach tens of thousands of times, more than several other secondary batteries.
- Small self-discharge. Li-polymer battery monthly self-discharge rate is only 6-8%, much lower than nickel-cadmium batteries (25-30%) and nickel-metal hydride batteries (30-40%).
- No memory effect. It can be charged at any time according to the requirement without reducing the performance of the battery.
- No pollution to the environment. Li-polymer batteries 🔋 do not exist in harmful substances, are a veritable “green battery”.
Batterie au lithium polymère
Q: What is a lithium polymer battery?
A: It’s a newer type of battery that hit the market around 1999. Unlike older lithium batteries that use a liquid electrolyte, lithium polymer batteries use a solid polymer for the electrolyte. The rest of the structure is pretty similar.
Q: How does the polymer electrolyte work?
A: The polymer electrolyte is basically a thin film that holds a solution. This solution has a main polymer, usually something like polyethylene oxide, which acts like a fixed, non-moving solvent.
Q: What are the advantages of lithium-polymer batteries?
A: They can be made in almost any shape and are lighter than older types. One big reason for this is that they don’t contain heavy metals. Plus, their plastic shell keeps the electrolyte from leaking, making them more reliable.
They all perform better. Ideally, lithium polymer batteries have a capacity of several thousand mA/h and are safer. The solid electrolyte acts like a hermetically sealed gel and does not readily disintegrate naturally during the charging process.
Lithium polymer batteries are in the same volume as the lithium battery 🔋 🪫 capacity. And no memory effect at all (li-polymer batteries still have a memory effect, just smaller). A lithium polymer battery is a gel-like substance. It is easy to make various shapes. And does not contain harmful heavy metal elements, is the “green battery”.
