Alkaline Vs. Lithium Battery



Everything now is about batteries, and lithium batteries are the rage now. Alkaline batteries have long been a popular battery, but with the increasing demand for electricity, rechargeable batteries, especially lithium-ion batteries, have become the mainstream. Now the good old alkaline battery has been dethroned by the lithium battery. Alkaline vs lithium batterieswhat are the advantages and disadvantages of them? There's no denying that the global need for clean energy is at an all-time high. As the areas of battery application and the need for affordable energy solutions continue to surge, you can't help but ask if the new king of battery technology—lithium-ion, is better than the old alkaline battery. Lithium batteries are much more pricey than the alkaline alternatives,lithium-ion batteries have 4,000 cycles, while most alkaline batteries are not rechargeable. So, is a lithium battery better than an alkaline battery?Alkaline vs lthium batteries, which battery is better lithium or alkaline?

1.What is lithium ion battery?

What is lithium-Ion Battery

When it comes to alkaline vs lthium batteries, we're going to first introduce what a lithium battery is. Lithium-ion batteries are rechargeable storage/power batteries. Lithium-ion batteries contain several basic materials: positive and negative electrodes, isolation film and electrolyte. The cathode electrode piece of lithium ion battery often uses aluminum foil, the cathode material is lithium compound, the negative electrode is carbon layer compound, generally common for graphite. This battery technology has found its use in many portable electronic devices, including smartphones and laptops.To understand alkaline vs lthium batteries, we must first clarify the advantages and disadvantages of these two batteries.

1.1 Advantages of lithium ion battery

If you're wondering why the lithium-ion battery is very much popular, perhaps a look at some of its many advantages can help you. Lithium-ion batteries do not produce any toxic and harmful heavy metals and substances such as lead, mercury and cadmium, do not contain highly toxic substances, and have relatively little pollution and great recovery value, making them an eco-friendly option Li-ion batteries have the highest energy densities of any battery, so they are light in weight and small in size They can hold a lot of power, making them the best choice for high-power applications These batteries require free maintenance They have a low self-discharge rate, the monthly self-discharge rate of lithium batteries is only 3.5% and has no memory effect.

1.2 Disadvantages of lithium ion battery

The disadvantages of li-ion batteries are generally few. Technological advancements are also making these disadvantages even lesser. With each passing day, manufacturers find ways to improve lithium-ion batteries and make them even more reliable. Still, there are always those shortcomings, and here, they include; Lithium-ion batteries are temperature sensitive and can quickly overheat Lithium-ion batteries have high manufacturing standards and high costs, but the average daily cost is low due to their long battery life Li-ion batteries require more safety mechanisms to control the voltage and internal pressures Almost all lithium battery packs are equipped with battery management system, which avoids the occurrence of over-charge, short-circuit and over-temperature, and solves some shortcomings of lithium-ion batteries, but also can realize intelligent control.

2.What is alkaline battery?

What are alkaline batteries

If we want to deeply understand alkaline vs lthium batteries, we also need to learn more about alkaline batteries. Easily the world's most popular household battery. From batteries in the wall clocks to remote controls, toys, flashlights, and a lot more—everything is about the alkaline battery. These batteries generate energy through the chemical reaction between their zinc and manganese dioxide electrodes. An alkaline electrolyte of potassium hydroxide or potassium also plays a huge role here. Originally, these batteries were non-rechargeable and disposable. Once drained, you need to dispose of them. However, many manufacturers have recently found a way to produce rechargeable alkaline batteries—another big boost to battery technology. But it can only be charged a few times, and the charging conditions are very strict.

2.1 Advantages of alkaline battery

Here are the advantages of alkaline batteries, both disposable and rechargeable alkaline batteries. Alkaline batteries are safe to use and don't short-circuit even if there is a power surge Zero or less worry about age as they have a longer shelf life and storage life Rechargeable alkaline battery will not lose voltage when stored They are a more affordable alternative compared to other options like lithium batteries.

2.2 Disadvantages of alkaline battery

Potassium hydroxide in alkaline batteries is liquid, with a relatively small internal resistance.

They can leak if kept in unused devices. Alkaline batteries are prone to leak potassium hydroxide, reducing the shelf life of the battery and causing circuit damage. Alkaline batteries contain zinc and manganese dioxide and can be toxic at higher concentrations;

Alkaline batteries have low power density, making them unfit for applications that require more power usage;

Rechargeable alkaline batteries have a short cycle life, can only be recharged a few times, and even most alkaline batteries are not rechargeable;

Alkaline batteries are pretty bulky.

3.What is the difference between lithium and alkaline AAA batteries?

What is the difference between lithium and alkaline AAA batteries

What’s the alkaline vs lthium batteries comparison?Lithium and alkaline AAA batteries offer enough energy to power up most of your household devices. But then, what's the difference between these two conflicting choices? The best battery type you can pick for your device today lies mainly in the difference between these batteries. Generally, the key factors differentiating Alkaline batteries from lithium batteries fall under their material, performance, power, cost, weight, and application.

3.1 Materials

What’s the Alkaline vs. lthium batteries materials difference?One huge factor pointing out the difference between alkaline and lithium battery is the material makeup. Alkaline vs. lthium batteries, these two batteries comprise of distinct materials. While Alkaline AAA batteries use zinc and manganese oxide to generate power, lithium batteries use lithium compound. The zinc (Zn) and manganese dioxide (MnO2) act as cathode and anode on alkaline batteries. And for an alkaline, the battery chemistry uses potassium hydroxide (KOH). On the other hand, lithium batteries use different forms of lithium compound, including Lithium Iron Phosphate (LiFePO4), Lithium Titanate (Li2TiO3), Lithium Cobalt (LiCoO2), Lithium Manganese Oxide (LiMn2O4). Lithium iron phosphate batteries are known as LFP batteries and lithium iron phosphate is used as a cathode material and a graphitic carbon electrode with metallic backing is used as the anode.

3.2 Power

What’s the alkaline vs lthium batteries power capacity difference?The power capacity from these batteries also serves as a significant key in differentiating them. Lithium-ion batteries have a high power tolerance, they can hold a lot more power than alkaline batteries. This means that the lithium batteries can power your device for a more extended period. Also, they can power devices with a high power demand.

3.3 Cost

What’s the alkaline vs lthium batteries difference?Price is another significant factor differentiating these two batteries. It's no news that you'll spend more to get an AAA lithium battery than an alkaline alternative. However, with lithium batteries having a longer cycle life than the alkaline alternative, they can save you money as you don't need to get a new battery more often.

3.4 Weight

What’s the alkaline vs lthium batteries weight difference?Lithium-ion batteries are small and lightweight because of their high size and light energy density.
