Lithium Battery Difference

The Lithium Difference

Lead acid batteries are made from (not surprisingly) a mixture of lead plates and sulfuric acid. This was the first type of rechargeable battery, invented way back in 1859.

Lithium ion batteries on the other hand are a much newer invention, and have only been around in a commercially viable form since the 1980′s.

Lithium technology has become well proven and understood for powering small electronics like laptops or cordless tools, and has become increasingly common in these applications – edging out the older NiCad (Nickel-Cadmium) rechargeable battery chemistry due to lithium’s many advantages.

LifePo4 Lithium iron phosphate cell LFP

But as you might recall from the many news stories a few years ago around defective laptop batteries bursting into flame – lithium ion batteries also earned a reputation for catching fire in a very dramatic fashion. The commonly used lithium ion battery formulation had been Lithium-Cobalt-Oxide (LiCoO2), and this battery chemistry is prone to thermal runaway if the battery is ever accidentally overcharged. This could lead to the battery setting itself on fire – and a lithium fire burns hot and fast.

This is one of the reasons that up until recently, lithium was rarely used to create large battery banks.

But in 1996 a new formula for mixing lithium ion batteries was developed – Lithium Iron Phosphate. Known as LiFePO4 or LFP, these batteries have a slightly lower energy density but are intrinsically non-combustable, and thus vastly safer than Lithium-Cobalt-Oxide. And once you consider the advantages, Lithium-Ion batteries becomes exceedingly tempting.

1/ Superior “Useable” Capacity

Unlike with lead acid batteries, it is considered practical to regularly use 85% or more of the rated capacity of a lithium battery bank, and occasionally more. Consider a 100 amp hour battery – if it was lead acid you would be wise to use just 30 to 50 amp hours of juice, but with lithium you could tap into 85 amp hours or more.

2/ Extended Cycle Life

Laboratory results indicate that you could expect to see 2000 to 5000 cycles out of a well cared for LiFePO4 battery bank. These are theoretical results but recent measurement shows that a battery will still deliver more than 75% of it’s capacity after 2000 cycles.

In contrast, even the best deep cycle lead acid batteries are typically only good for 500-1000 cycles.

3/ Fast & Efficient Charging

Lithium-ion batteries can be “fast” charged to 100% of capacity. Unlike with lead acid, there is no need for an absorption phase to get the final 20% stored. And, if your charger is powerful enough, lithium batteries can also be charged insanely fast. If you can provide enough charging amps – you can actually fully charge a lithium ion battery just 30 minutes.

But even if you don’t manage to fully top off to 100%, no worries – unlike with lead acid, a failure to regularly fully charge Lithium-Ion batteries does not damage the batteries.

This give you lots of flexibility to tap into energy sources whenever you can get them without worrying about needing to do a full charge regularly. Several partly cloudy days with your solar system? No problem that you can’t top off before the sun goes down, as long as you’re keeping on top of your needs. With lithium, you can charge up what you can and not fret about leaving your battery bank perpetually undercharged.

4/ Very Little Wasted Energy

Lead acid batteries are less efficient at storing power than lithium ion batteries. Lithium batteries charge at nearly 100% efficiency, compared to the 85% efficiency of most lead acid batteries.

This can be especially important when charging via solar, when you are trying to squeeze as much efficiency out of every amp as possible before the sun goes down or gets covered up by clouds. Theoretically, with lithium nearly every drop of sun you’re able to collect goes into your batteries. With limited roof & storage space for panels, this become very important in optimizing every square inch of wattage you’re able to mount.

5/ Climate Resistance

Lead acid batteries and lithium lose their capacity in cold environments. As you can see in the diagram below, Lithium-ion batteries are much more efficient at low temperatures. Moreover, the discharge rate affects the performance of lead acid batteries. At -20°C, a Lithium battery that delivers a 1C current (one times its capacity), can deliver more than 80% of its energy when the AGM battery will deliver 30% of its capacity. For harsh environments (hot and cold), Lithium-Ion is the technological choice.

Capacity vs temperature

6/ Fewer Placement Issues

Lithium-ion batteries do not need to be stored upright, or in a vented battery compartment. They can also fairly easily be assembled into odd shapes – an advantage if you are trying to squeeze as much power as possible into a small compartment. This is especially useful if you have an existing battery bay that is limited in size, but you want or need more capacity than lead acid is currently able to provide.

7/ Little Maintenance Requirements

Lithium-Ion batteries are fairly maintenance free. A “balancing” process to make sure all the cells in a battery bank are equally charged is automatically achieved by the BMS (Battery Management System). Just charge you battery and you are good to go.

8/ Peukert’s Losses & Voltage Sag Virtually Non Existant

The discharge curve of lithium batteries (especially relative to lead acid) is essentially flat – meaning that a 20% charged battery will be providing nearly the same output voltage as an 80% charged battery. This prevents any issues caused by the “voltage sag” common to lead acid as they discharge, but does mean that any battery monitor or generator auto-start dependent upon voltage levels will likely not work well at all when monitoring a lithium bank.

Lithium-Ion discharge curves

On the flip side, once lithium batteries are fully discharged, their voltage takes a nose-dive quickly – which is the BMS role to protect the batteries to absolutely never let this happen. Completely discharging a lithium ion bank, even once, can render your entire pack permanently dead.

Another huge advantage of lithium batteries is that Peukert’s losses are essentially non-existant. This means that Lithium-Ion batteries can deliver their full rated capacity, even at high currents. Whereas lead acid can see as much as a 40% loss of capacity at high loads. In practice, this means that Lithium-Ion battery banks are very well suited to powering high current loads like an air conditioner, a microwave or an induction cooktop.

9/ Size & Weight Advantages

To highlight the unique characteristics in terms of weight and size of the lithium-ion batteries, let’s take concrete example : lead acid vs Lithium battery.

Thunder Sky Winston Battery Limited invested a new production factory in Xiamen,China

Thunder Sky Winston Battery Limited invested a new production factory in Xiamen,China

Thunder Sky Winston battery Limited from Hongkong is a leading lithium ion phosphate battery (LiFePO4) battery producer with a factory in Shenzhen.now they are building their second factory in XiaMen, Southeast of China.

with investment of 350milion US$, the new factory would become one of big lifepo4 battery producer all over the world.and the full capacity would be as much as 1billion ampere hour per year.

Thunder sky winston battery limited was founded by Mr Zhong Xin jia in 1,998 in shenzhen,50km north of Hongkong.

they first created the big prismatic lifepo4 battery and their battery is very popular in United States and European market because there are a lot people convert their car to electric vehicles.instead of Song and LG, Thunder sky winston produce big lithium battery cells and the capacity of each cell as much as 100Ah and 200Ah.they have 40Ah, 60Ah, 90Ah,100Ah, 160Ah, 200Ah, 300Ah, 400Ah, 700Ah and 1000Ah battery cells.

its really easy to assemble the cells for a battery pack.
