Difference Between Lead Acid Battery and Lithium-Ion Battery Explained

If you are new to the world of electric scooters, you might know that the electric scooter is powered by a battery but did you know that there are 2 types of battery used in electric scooters? These two batteries are called lead acid battery and lithium ion battery. We have already explored the Impact Of Battery Price On The Overall Cost Of Owning An E-Scooter. The topic in focus is which one of these two batteries is better? Let’s weigh out the pros and cons of each of them and find out who prevails between the battle of lead acid battery vs lithium ion battery. 

‍

Battery Basics: A Grounding in Electrochemistry

‍

‍

Before we unleash the battery brawl, let's establish some fundamental knowledge. Both lead acid and lithium ion batteries function through the world of electrochemistry. They are for example miniature power plants that use chemical reactions to store and release energy. These reactions involve the movement of charged particles (electrons) between different components within the battery, creating the electricity that fuels our devices. This is how essentially a battery works regardless of what the type of battery they are. 

‍

Lead Acid: The Reliable Option

‍

Lead acid batteries are the seasoned veterans of the battery world. They have been in place since the 1850s, they've powered countless cars, motorcycles, and even some golf carts for over a century.

‍

A look inside of a lead acid battery –

• Anode and Cathode: These are the battery's power players, constructed from lead plates submerged in a sulfuric acid solution (the electrolyte). During discharge, lead atoms from the anode lose electrons and migrate to the cathode, generating an electric current.
  
  
• Electrochemical Process: As these electrons move, lead sulfate forms on both plates. Recharging reverses the process, converting lead sulfate back to lead and sulfuric acid, essentially rewinding the battery and making it ready for action again.
  
  

Lithium Ion: The Energetic Newcomer 

‍

Lithium ion batteries are the newer edition of batteries. They're the power source behind our laptops, smartphones, and have been increasingly been adopted in EVs. Think of them as the energetic whippersnappers, boasting lighter weight, faster charging times, and impressive power capabilities.

‍

Now, let's crack open a lithium ion battery:

• Anode and Cathode: These are made from various lithium compounds and metal oxides. During discharge, lithium ions flow from the anode to the cathode, generating electricity in the process.
  
  
• Electrochemical Process: Unlike lead acid batteries, lithium ions move between the electrodes without physically changing them. Recharging simply pushes the lithium ions back to the anode, prepping the battery for another round of powering your devices.
  
  

Cost Comparison: Short-Term Savings vs. Long-Term Value

‍

When it comes to cost objectively between lead acid battery vs lithium ion battery, lead acid batteries typically have a lower upfront cost, making them an attractive option for budget-conscious consumers. However, like that tempting bargain bin purchase, they might not last as long. Lithium ion batteries often have a higher initial price tag, but their extended lifespan, higher efficiency, and lower maintenance requirements can make them more cost-effective in the long run.

Consider it an investment in a reliable and long-lasting energy source. For anyone considering between the two if budget is absolutely not an issue, then it is a no brainer to opt for a lithium ion battery.

‍

Capacity and Energy Density: More Power in a Smaller Package

‍

Imagine trying to fit all your clothes into your carryon luggage. That's the key advantage lithium ion batteries have over lead acid battery. They boast a significantly higher energy density, meaning they pack more energy into a smaller and lighter form factor. This makes them ideal for powering our ever-shrinking tech gadgets and electric vehicles that require long travel distances on a single charge. Lead acid batteries, while powerful, are bulkier and can limit the design and portability of devices. Newer devices tend to integrate Lithium ion batteries rather than lead acid batteries. 

‍

Weight and Size Efficiency

‍

Speaking of portability, lithium ion batteries are significantly lighter than their lead acid counterparts. This is a game-changer for mobile devices like laptops and smartphones, where every gram counts. Imagine lugging around a brick of a battery compared to a featherweight lithium ion option – your back (and your arms) will thank you! This lighter weight also contributes to the overall efficiency of electric vehicles, as less energy is wasted on hauling around a heavy battery pack.

‍

Bounce Infinity is a great example of the light weight factor when it comes to Lithium Ion Battery. The scooters by Bounce Infinity sport a detachable battery which is lithium ion, for the purpose of ease of charging. The rider can simply detach the battery from the scooter and take it home to charge the battery at the convenience of their own home. 

‍

Depth of Discharge (DOD) and Efficiency

‍

Not all the energy stored in a battery is usable. Depth of Discharge (DOD) refers to the percentage of a battery's capacity that can be utilized before needing a recharge. Here's where lithium ion shines again. They boast a higher DOD, meaning you can squeeze more usable energy out of them compared to lead acid batteries. This translates to longer run times and fewer charging interruptions for your devices, keeping you connected and productive for extended periods.

‍

Durability and Cycle Life: Built to Last 

‍

Both lead acid and lithium ion batteries degrade over time with repeated charging and discharging cycles. This is where lithium ion takes the lead though. They generally offer a longer lifespan and higher cycle life compared to lead acid batteries. This means you can expect to replace your lithium ion battery less frequently, saving you money in the long run and reducing electronic waste. Here's a deeper dive into the factors affecting battery lifespan:

‍

• Depth of Discharge: Operating a battery at a high DOD (frequently discharging it close to empty) can accelerate its degradation. Lithium ion batteries, with their higher usable capacity, allow for shallower discharges, contributing to their longer lifespan.
• Temperature: Extreme heat or cold can damage both battery types. However, lithium ion batteries are generally more sensitive to high temperatures, which can trigger internal chemical reactions and degrade the battery faster. Following proper storage and charging practices in moderate temperatures is crucial for maximizing battery life.
• Charging Habits: Rapid charging, while convenient, can put stress on batteries and shorten their lifespan. Lithium ion batteries are often better suited for quick-charging technologies due to their inherent design, but following manufacturer recommendations for both battery types is essential.

‍

Charging Time and Maintenance Needs

‍

Lead acid batteries being older, it can take several hours to fully charge, while lithium ion batteries can be recharged much faster, especially with advancements in quick-charging technology. Think about it – waiting all day for your phone to charge versus a quick top-up during your lunch break. Lithium ion batteries also require less overall maintenance throughout their lifespan. While both types benefit from proper storage and avoiding complete discharge, lead acid batteries might require additional maintenance like topping up electrolyte levels (a process that can be messy and requires safety precautions).

‍

Safety, Installation, and Storage

‍

Lead acid battery vs lithium ion battery can both pose safety risks if mishandled. Overcharging can lead to overheating and potential explosions. Always follow manufacturer recommendations for charging and storage. However, lithium ion batteries are generally considered more volatile than lead acid batteries due to the presence of lithium metal. They require specific voltage regulations and charging protocols to ensure safety. When it comes to installation, lead acid batteries offer more flexibility, while lithium ion batteries might require specialized charging systems or be integrated into the device itself. It's crucial to consult the user manual and follow proper safety guidelines for both battery types.
