The electrolyte of a lithium-ion battery is usually a liquid electrolyte, which contains lithium salts and organic solvents. The advantage of this type of battery is that it can provide high power output, so it is suitable for applications that require fast charging and discharging. The downside of lithium-ion batteries is the risk of leakage and explosion at high temperatures because the liquid electrolyte is easily affected by the outside environment.
In contrast, the electrolyte of lithium polymer batteries is a solid polymer, so it is safer and more stable. The advantage of this type of battery is that it has a higher energy density and therefore can provide a longer operating time. Lithium polymer batteries have the disadvantage of lower power output, making them unsuitable for applications that require a large amount of energy output.
In addition to the difference in electrolyte, lithium-ion batteries and lithium-polymer batteries are also different in other ways. For example, the electrode material of lithium polymer battery is usually lithium cobalt oxide, while the electrode material of lithium ion battery can be lithium cobalt oxide, lithium iron phosphate, etc.
In practical applications, which battery type to choose depends on the specific needs. For example, if you need high power output, you should choose Li-ion batteries; if you need higher energy density and safer batteries, you should choose Li-polymer batteries.
