As the core component of energy storage, the optimization and innovation of battery performance directly affect our lives. Lithium-ion polymer batteries and lithium-ion batteries have gradually become popular products in the market.
This article mainly talks about the comparison of lipo battery vs li ion battery from definition, features to their actual use.
Definition of lipo battery vs li ion battery
Lithium polymer battery (lipo battery) is a rechargeable lithium-ion battery that uses a semi-solid or colloidal polymer material as its electrolyte, rather than a liquid electrolyte.
Lithium ion batteries are a type of secondary battery (rechargeable battery) that primarily rely on the movement of lithium ions between the positive and negative electrodes to function. The lithium ion electrolyte is liquid and exists in the form of gel and polymer.
Features of lipo battery vs li ion battery
The comparison of lipo battery vs li ion battery in terms of performance, energy density, shape, and safety. The following is a comparison of the performance of these two types of batteries.
Energy density
Lithium polymer batteries, due to the special properties of their electrolytes and the use of polymer materials, can be assembled into multiple layers within the battery cell to achieve high battery life. On the premise of ensuring safety, further enhance energy density through a tighter stacking design. During production, the thinner the polymer battery, the better, making it more advantageous in fields with strict requirements for weight and volume, such as drones and wearable devices.
Lithium ion batteries high energy density achieved by optimizing positive and negative electrode materials and electrolyte formulations, meeting the needs of most consumer electronics products. The nominal capacity of lithium battery cells is 3.6V or 3.7V, which can connect multiple cells in series to form an ideal high-voltage working platform. When making, the thicker the lithium battery, the better the production, which makes lithium batteries more versatile in terms of applications.
Shape
Lithium polymer batteries are known for their thinness, flexibility, and the ability to achieve thinning, arbitrary area, and arbitrary shape, due to the fact that their electrolytes can be solid or colloidal rather than liquid.
Lithium ion batteries use electrolytes, usually packaged in cylindrical or square shapes, with a positive electrode, negative electrode, electrolyte, and separator inside. The secondary packaging contains the electrolyte to ensure the stability and safety of the battery. Therefore, this also adds some weight to lithium batteries.
Safety
Lithium ion batteries with liquid electrolytes pose a risk of fire and explosion in extreme situations such as overcharging and short circuits.
In contrast, lithium polymer batteries effectively reduce this risk and improve overall safety due to the use of solid or semi-solid electrolytes. However, it is worth noting that when organic electrolytes are used inside polymer batteries, if the instantaneous current is large enough to cause a short circuit, it is not impossible for the battery to self ignite or burst. Safety accidents in mobile phones and tablets are often caused by this situation.
Llipo battery vs li ion battery in use
Usage time
Lithium polymer batteries stand out with their higher energy density. This means that under the same volume or weight, lithium polymer batteries can store more energy and provide devices with longer battery life. For devices such as smartphones and drones that pursue lightweight and portability, lithium polymer batteries are undoubtedly a better choice.
In the case of lipo battery vs li ion battery, lithium-ion batteries often have a better cycle life, especially in high-temperature environments where their performance degradation rate is relatively slow. This is particularly important for applications such as electric vehicles that require long-term stable operation.
Cost
The production technology of lithium-ion batteries is relatively mature, with significant economies of scale, which gives them a certain cost advantage.
However, although lithium polymer batteries may require higher initial investment, their lightweight and high energy density characteristics can bring higher cost-effectiveness in specific application scenarios.
Applications
Lithium ion batteries dominate in electric vehicles, energy storage systems, and most consumer electronics products due to their mature technology, stable performance, and relatively low cost. Especially in the field of electric vehicles, with the continuous advancement of technology and the continuous decline of costs, lithium-ion batteries are gradually driving the automotive industry towards a more environmentally friendly and efficient direction.
Lithium polymer batteries, on the other hand, shine in emerging fields such as drones, wearable devices, and intelligent medical devices due to their lightweight, flexible, and high safety characteristics. These devices often have strict requirements for the shape, size, and weight of batteries, and lithium polymer batteries precisely meet these needs, driving the rapid development of these industries.
