Polymer Lithium Battery

Polymer Lithium Battery

Polymer lithium battery is a new type of rechargeable lithium batteries. It uses aluminum plastic flexible packaging and a gel electrolyte instead of the liquid electrolyte used in liquid lithium batteries. It has better quality and safety features.

Gel-based polymer electrolytes have excellent ionic conductivity and thermal stability, allowing for efficient ion transport between the cathode and anode. This improves battery performance and allows it to charge and discharge quickly.

High Energy Density

The energy density of a battery refers to the amount of electrical power it stores per volume unit, and is a key measurement for mobile devices. It is measured in Wh/kg, a more precise unit than the more commonly used mAh/g (milliampere hours per gram) that refers to energy per charge.

Li-polymer batteries have a high energy density and are able to store more energy than traditional nickel-cadmium, lithium-ion and nickel-metal-hydride cells, making them a good choice for electric vehicles, for example. The highest-energy lithium-polymer cell so far has a capacity of 700 Wh/kg, and researchers are working to achieve even higher energy densities.

To achieve a high energy density in solid-state lithium batteries, it is important to make sure that the positive and negative electrodes are well connected. This can be difficult with conventional liquid lithium batteries, because the separator and electrolyte are both liquids. Li-polymer batteries, on the other hand, use a solid polymer to separate the positive and negative electrodes. This allows the battery to be much thinner than conventional batteries, and it also has a higher mechanical strength.

To ensure that the positive and negative electrodes are connected properly in a polymer lithium battery, researchers have developed different methods to make an interpenetrated polymer lithium battery network of conductive polymers. These networks can be formed by combining ion-conductive poly(ether-acrylate) (ipn-PEA) with branched acrylates, and this approach can prevent polymer crystallization and promote Li+ migration. This also guarantees continuous contact between the solid components for smooth charge transport, and it maintains a stable structure that ensures a long battery lifespan.


Lithium polymer batteries are very convenient and portable because they can be made into a variety of shapes and sizes. They are also much more lightweight than lithium-ion batteries, as they don’t contain any weighty metals or liquid electrolyte. This makes them ideal for use in small electronic devices, such as mobile phones and tablets.

They have a low self-discharge level, meaning that they won’t go flat when you aren’t using them. This is because they aren’t constantly consuming electricity to recharge themselves, and they have a smaller internal resistance than ordinary lithium-ion batteries.

Another advantage of lithium-polymer batteries is that they are safe to transport. The cells are structured in soft aluminum-plastic packages, which are different from the hard cases of liquid lithium batteries. This means that the battery cannot explode if it has a safety hidden problem, like a leakage. Instead, it will simply swell up.

The batteries are also free of toxic metals, such as cadmium and mercury. They are able to perform more charging cycles and have better cycle life than other battery types, such as nickel-metal hydride batteries. In addition, professional battery factories like Grepow have passed ISO14000 environmental system certification and the products comply with RoHS directive. They are highly recyclable and can be recycled into new batteries with little energy loss.

Low Mold Opening Cost

Batteries are a vital component in digital products, supplying power for many devices. However, batteries can be a safety hazard when mishandled or misused. For example, if the battery’s internal chain reaction goes wrong, it can cause a thermal runaway. This process can lead to explosions and fires, as well as the release of hazardous fumes. Fortunately, this problem can be avoided with the use of lithium polymer batteries.

Lithium polymer batteries are made from a soft aluminum-plastic packaging, which Solar energy storage system makes them safer than liquid lithium batteries. Additionally, they are much more flexible. The cells can be molded into different shapes, making them more compact and lightweight than traditional lithium-ion batteries. They can also be built with any size to fit the needs of a particular application.

Compared to liquid lithium batteries, these batteries have a lower mold opening cost and a shorter manufacturing cycle. They can also be customized flexibly to meet the voltage and capacity requirements of any application. In addition, they have a longer lifespan and can be charged and discharged many times.

Unlike nickel-cadmium and lithium-ion batteries, which are susceptible to memory effect, lithium polymer batteries do not lose their charge capacity over time. They are also less prone to temperature changes, so they can be used in a wide range of conditions. Additionally, they are less likely to leak than other types of batteries, and can be safely shipped in large quantities.

High Safety

As lithium-polymer batteries are becoming more popular, people are starting to ask more questions about the safety of these batteries. They are safer than traditional lithium-ion batteries because they do not contain any metals, making them less prone to fire and explosion. They are also not as sensitive to heat and have an extended cycle life, making them more durable and dependable.

In addition, the semi-solid electrolyte in polymer lithium batteries makes them resistant to leakage, which is an issue that affects Li-ion batteries. This feature is especially useful in electronic devices that need to provide power at high rates, such as drones and electric cars.

However, it is important to note that even though these batteries have a safe design, they must still be used with caution. The internal plastic separator between the anode and cathode can be damaged by physical abuse, such as dropping, crushing, vibrations, or exposure to water. This can cause the anode and cathode to come into direct contact, resulting in elevated temperature and gas generation within the battery cell. This can lead to a thermal runaway and a battery fire.

To help prevent this from happening, MaxAmps’ lithium-polymer packs feature a balancing tap that connects to an industry standard balance charger. This ensures that the voltage of each cell is the same, and this prevents over-charging or over-discharging and improves cycle life.
