LiFePO4 Vs Lithium Ion Charging

Introduction

It's not always easy to plug in new batteries when power sources are being used to drive embedded components. Batteries that can store a sizable quantity of energy, are light enough to carry or move, and are safe for the user are needed for newer technology, such as smartphones, electric vehicles, and portable power tools. For portable gadgets, motor vehicles, medical devices, and even grid energy storage, lithium batteries provide all these advantages.

Today's portable gadgets use two different types of batteries: lithium-ion and lithium iron phosphate. Despite certain parallels between them, there are significant variances in terms of high energy density, lengthy life cycles, and safety. As most people own a phone, tablet, or computer, they are certainly familiar with lithium-ion technology. Due to its inexpensive components and resilience in high temperatures, lithium iron phosphate batteries are a more recent form of battery that are gaining popularity in the manufacturing industries.

LiFePO4 Vs Lithium Ion Charging

Lithium ion and lithium iron phosphate cell charging are extremely similar. Both employ constant voltage followed by constant current for charging. Solar or desktop charging typically requires the use of two pieces of equipment when referring to one of the DIY battery packs from the channel. The voltage and current source come first. This might be a solar panel or an adjustable buck, for instance. The charging controller comes next. The BMS is fed by this, which controls the voltage and current leaving our voltage/current source.

The BMS then transmits the pack with the prescribed voltage. Moreover, cells with higher voltages than the rest lose voltage due to this phenomenon. The others will now have an opportunity to catch up. Never connect an unregulated source directly to your battery, whether it has a BMS or not.

LiFePO4 Vs Lithium Ion Energy Density 

The energy density of a battery indicates how much power it contains in comparison to its weight. This amount is typically expressed as Watt-hours per kilogramme (Wh/kg). Watt-hours are the unit of electrical energy equivalent to one watt utilised for one hour. Power density evaluates the energy's delivery speed rather than the amount of energy that is currently accessible in storage. Given that they are commonly used interchangeably, understanding the distinction between power density and energy density is essential. To better understand lithium-ion batteries, you need understand why a high energy density is a desired quality in a battery. A battery with a high energy density has a longer operating time relative to its size. The energy density of a battery indicates how much power it contains in comparison to its weight.

The opposite is also true: a battery with a higher energy density can deliver the same amount of power while occupying less space than a battery with a lower energy density. The potential battery usage are greatly expanded as a result. In warehouse or production settings, forklift batteries can weigh thousands of pounds. Lightweight forklift batteries provide several advantages in terms of handling and safety.

The increased energy density of a battery could be dangerous. A cell that contains more active material is more likely to experience a thermal event.

The energy value of the batteries is the first and most significant difference. Energy density for the lithium-ion battery ranges from 150 to 200 Wh per kg. Lithium-iron phosphate has an energy density of between 90 and 120 Wh per kilogramme.

This energy disparity demonstrates unequivocally that lithium-ion drains batteries more quickly than LiFePO4 does. Moreover, compared to LiFePO4 batteries, lithium-ion batteries have a higher voltage discharge capability.

Despite the fact that the chemical composition of lithium-ion batteries can vary widely and have an impact on their performance, they are occasionally categorised as a type of battery that all include lithium.

The majority of lithium-ion battery types consist of an aluminum-backed cathode, a carbon or graphite anode, a separator, and an electrolyte made of lithium salt in an organic solvent.

The makers have tested the components used to make the cathode and anode. The chemical composition of the electrolyte has also changed. These variances result in the different energy densities of lithium-ion batteries.

LiFePO4 Vs Lithium Ion Safety

Batteries made of phosphate provide an excellent chemical and mechanical structure that doesn't overheat dangerously. Hence, it offers more safety than lithium-ion batteries built with other cathode materials. This is due to the fact that LiFePO4's charged and uncharged states are physically comparable and extremely durable, allowing the ions to remain stable during the oxygen flux that occurs along with charge cycles or potential failures. Overall, the iron phosphate-oxide bond is stronger than the cobalt-oxide bond, so it remains structurally stable when the battery is overcharged or subject to physical damage. In contrast, in other lithium chemistries, the bonds start to break down and release excessive heat, which eventually causes thermal runaway.

The incombustibility of lithium phosphate cells is a crucial property non the event of errant handling while charging or discharging. They can also withstand adverse weather conditions including harsh cold, scorching heat, or rough terrain. They won't blow up or catch fire when exposed to risky situations like collisions or short circuits, thus lowering the likelihood of injury. LiFePO4 is probably your best option if you're choosing a lithium battery and want to utilise it in dangerous or unstable conditions. It's also important to note that LiFePO4 batteries are an environmentally friendly option because they are non-toxic, non-contaminating, and don't contain rare earth metals.
