Lithium polymer batteries are well established products in the battery industry. Lithium polymer is widely loved and used due to the superior performance of the battery and the ability to customize it on demand as well as other advantages.
Graphene is considered as one of the most promising materials in the future. The performance of graphene battery is much better than lithium battery, especially in terms of power characteristics, electric capacity and lifetime of the battery. However, graphene has not yet reached the practical stage, and there is still a long way to go before mass production.
What Is LiPo Battery?
Lithium polymer battery, also known as lithium polymer battery, is a kind of chemical nature battery. Compared to the previous batteries, lithium polymer batteries have high energy, miniaturization and light weight.
Lithium polymer batteries have ultra-thin characteristics and can be made into different shapes and capacities to match the needs of some products.
What Is Graphene Battery?
Graphene battery, a honeycomb-like planar film formed by carbon atoms in sp2 hybridization, is a quasi-two-dimensional material with only one atomic layer thickness, so it is also called single-atom layer graphite.
Graphene battery is a new energy battery developed by using the property of rapid and massive shuttle movement of lithium ions between graphene surface and electrodes.
Due to its high electrical conductivity, high strength, and ultra-thinness, graphene is also extremely advantageous for aerospace special applications. In addition, it is chemically inert, making it an environmentally friendly and sustainable material.
So what are the differences between Graphene batteries and LiPo batteries?
Difference between Graphene Battery and LiPo Battery
The following table provides a quick overview of the differences between the two types of batteries.
|Life and Cycles
|Mostly around 300 cycles
|About five times the capacity of traditional batteries; more than 400 cycles; more than three times the service life of lithium batteries
|Impact on the Environment
|Harmful to the environment to some degree
|More environmentally friendly
|Dangerous to use improperly
|Light-weighted and flexible
|Not so expensive
Think it’s not enough? Sure, let’s move on to a more detailed comparison.
Expanding from the seven aspects in the table, let’s explore the differences between graphene and LiPo batteries in detail.
Life and Cycles
Battery life and cycle time is an important factor to consider when we use batteries. A battery with a longer life span is less worrying and less expensive to use.
Most LiPo batteries cannot be recharged more than 300 times. Over time, the capacity of a LiPo battery decreases, and then the life of the device decreases, and this is an irreversible process. The LiPo battery will continue to decline until it can no longer be charged and discharged for use.
Graphene batteries store three times the power of the best products on the market today. A lithium battery (whichever is the most advanced) has a specific energy value of 180wh/kg, while a graphene battery has a specific energy of over 600whkg.
Its lifetime is five times that of a conventional hydrogenated battery and more than three times that of a lithium polymer battery.
Performance is the most important factor that affects whether a battery is good or bad.
LiPo batteries have superior performance; they are smaller, lighter, and have a higher energy capacity than lithium-ion batteries. LiPo batteries are considered an improvement over lithium-ion batteries.
LiPo batteries have a higher specific energy than traditional lithium batteries.
They are very lightweight and therefore used in products where weight is a significant feature, such as cell phones or radio-controlled aircraft.
High energy density. The volume energy density and mass energy density of Li-polymer batteries can reach 450W.h/dm3 and 150W.h/kg respectively, and they are still improving.
Low self-discharge rate.
The energy density of graphene battery is 225 Wh/kg.
The performance of graphene battery is more powerful. They are also more durable than lithium batteries at high temperatures. It has a larger storage capacity.
Impact on the Environment
More environmentally friendly batteries will better protect the environment around us.
LiPo batteries contain elements that are harmful to the environment. After the batteries are disposed of, they can cause damage to the environment if not properly recycled.
Graphene is a good conductive material, so there is no need to add more carbon, making these batteries greener and more environmentally friendly.
Faster charging speed helps you get rid of the hassle of charging cables
Can be charged and discharged quickly, with a capacity of more than 80% of the nominal capacity at 1C charging.
High charging efficiency, basically 100% after the 1st cycle.
Faster charging. Huawei’s fast charging technology charges a 3,000 mAh graphene battery to nearly half its capacity in just five minutes.
Graphene batteries can be increased by tens or even hundreds of times.
Safety is always the first priority no matter what. Unsafe batteries can cause fires, explosions, and even endanger lives.
Lithium polymer batteries can cause safety problems if overcharged, which can lead to fire or even explosion in serious cases.
Graphene batteries are safe and stable, and more durable than lithium polymer batteries at high temperatures, which also means that graphene batteries are safer than lithium polymer batteries at high temperatures.
Graphene batteries do not have the potential to explode.
Lightweight batteries are easy to carry.
LiPo batteries are lightweight and can be customized in shape and size as needed.
Graphene batteries are lightweight and thin. The properties of graphene allow the weight of the battery to be reduced to half that of a conventional battery, which increases the efficiency of the machine loaded with the battery.
Price certainly matters. Value for money is always something that people seek.
Lithium polymer batteries are not too expensive and are already very common in the market.
Graphene is expensive. Highly conductive graphene currently sells for as much as $600 per gram and is known as “black gold”.
At the same time, the process of manufacturing graphene batteries is also very demanding. This is also an important reason why Graphene batteries are not mass-produced and used in the market in large quantities.
Yes, I konw it’s hard to choose between them for both have pros and cons.
Graphene batteries are very superior performance batteries, but they are very expensive.
While lithium polymer batteries are not expensive. And, the performance of lithium polymer batteries is quite not bad. However, you need to be aware that when using lithium polymer batteries, you should follow the manual and rules of the battery to avoid problems such as overcharging.
So, you should choose between the two batteries according to your needs and ability to pay.
