With electric vehicles (EVs) becoming more prominent in the world, there are significant battery technology advancements that are leading the movement. EV battery technology holds the key to unlocking the full potential of electric cars and their advancements. The use of electric vehicles is a form of clean energy that combats the usual gasoline powered cars. The batteries that power these EVs are complex and dependent on multiple factors, making technology advancements important for an improved industry. This blog post explores the types of technology used in EV batteries, as well as new technology advancements that are improving the EV battery industry.

What Technology is used in EV Batteries?

EVs primarily use batteries powered by lithium ion technology, which has become the industry standard for powering modern electric cars. These batteries are seen as ideal for EVs as they are lightweight, have high energy efficiency, and perform well in different temperatures. Specific types of batteries like lithium iron phosphate (LFP) are an improvement on the lithium iron battery, having a longer lifespan and a wider temperature range. These advancements in technology further improve charging speed, safety, and sustainability, paving the way for more efficient and eco-friendly EV batteries in the future. Our battery technology for the Roadie Portable consists of lithium ion batteries, allowing a fast and efficient charge to be delivered at any time from any location.


Nickel Manganese Cobalt (NMC) Battery

The way this technology works is complex, but to put it simply, lithium ion batteries are able to hold a high voltage that can support a fast and efficient charge. There are other types of battery technologies including the nickel manganese cobalt (NMC) battery which are faster charging and last longer, but come at a more expensive cost. Although the NMC battery may be more efficient in nature, there is a higher risk for them to catch fire in the case of a malfunction. NMC requires battery materials that are harder to locate, making them much harder to manufacture on a large scale. 


Solid State Battery

Solid state batteries are another type of technology that replaces the liquid or gel-like electrolyte found in traditional batteries with a solid material. In a traditional battery, the movement of ions happens through a liquid or gel. However, in a solid state battery, the solid electrolyte enables the transfer of ions without the need for a liquid. This advanced battery technology can offer benefits including increased safety since the battery is less prone to leaking, as well as faster charging since the ions can move through the solid state faster than the liquid state. Still, solid state batteries hold downsides including a complex manufacturing process and an increased cost compared to regular lithium ion batteries.


Lithium Sulfur Battery

Lithium sulfur batteries is another form of a lithium ion battery. Sulfur is the main material used that allows for greater energy storage, as well as longer lasting power for the EV. Sulfur is a cost effective and widely available material, making the production of these batteries relatively easy. The main challenge of this battery type is the charging cycle. While lithium ion batteries are able to go through thousands of charge cycles and provide a long lifespan for their EV, lithium sulfur batteries fail to complete nearly as many charging cycles. The sulfur wears down on the other parts of the battery, leading to a shorter lifespan compared to that of lithium ion batteries.


Who is developing new EV battery technology? 

Most recently, the US Department of Energy has been making breakthroughs in creating longer range lithium ion batteries, which could lead to an increase in charging power and EV capabilities. This advanced battery technology will potentially lead to a greater increase in popularity for EV use, making products like the Roadie Portable more needed than ever. The Roadie is a new EV technology that is immediately deployable, being able to provide much needed charge from any place at any time. It consists of modular batteries, which are stackable to add range that can fit all types of charging needs. Here at SparkCharge, we are in constant development of new EV technology that will improve charging time and convenience for all fleets and drivers. 



Toyota has also been able to make a significant breakthrough in the development of EV technology. With their new advancements in solid state EV battery technology, they have been able to create a battery that sees a 10% reduction in cost and a 20% increase in range. Although there are numerous signs that point to new types of batteries becoming the standard in the EV industry, lithium ion batteries are still currently the leading technology when considering all factors. Toyota plans to roll out their new battery types in 2026 and 2027, which could lead to a change in what EV battery is considered to be the standard. 


What is the Best Battery Technology for EVs? 

Although there are many forms of EV batteries available on the market, lithium ion batteries have come out on top for a number of reasons. There is a well established manufacturing process and strong life cycle that make these batteries the option of choice. Considering the common EVs like hybrid electric vehicles (HEVs) and plug in hybrid electric vehicles, lithium ion batteries prove to be the best option. 


What are the benefits of Lithium Ion Batteries?

1. Charging Speed

Fast charging is a critical factor for picking the right battery. Lithium ion batteries have improved in terms of charging speed for their cost and wide availability. With a wide range of options including portable chargers and charging delivered here at SparkCharge, lithium ion batteries are equipped to power EVs for personal and fleet use. By using our Roadie Portable or charging-as-a-service (CaaS) programs, charging speed and efficiency will be easier than ever. We offer Level 3 (DC Fast Charging) which is the most efficient charging option, getting your EV back on the road quicker than ever. 


2. Energy Density

Lithium ion batteries currently offer a good balance between energy density and weight, allowing EVs to travel longer distances on a single charge without the struggle of frequent charging. Researchers are exploring other technologies, like solid state batteries and lithium sulfur batteries, which can improve the energy density of lithium ion batteries and energy storage. Still, the energy density offered by lithium ion batteries is extremely efficient and reasonable for its cost. 


3. Cost

The cost of batteries is a major factor in choosing the best battery option for an EV. Lithium ion batteries have seen significant cost reductions over the years due to increased production and wide availability. Other technologies like solid-state batteries are currently more expensive to manufacture which makes them less ideal for fleet use and large scale production. 


4. Safety 

Lithium ion batteries are an overall safe option. Although there is always the risk of overheating, this should not be a problem if the lithium ion batteries are treated with care. They are safe as car batteries as long as proper steps are taken to preserve their lifespan. 


5. Durability

Long lifespans and the capacity for reliable, consistent charging are crucial for EV batteries, ensuring they fully support the car's performance. Lithium ion batteries have made significant strides in this area, being able to power EVs for both commercial and personal use. Driving range is an important factor for all EVs, with lithium ion batteries being the best option to power many miles of travel. 


Overall, battery technology advancements have collectively played a vital role in making electric vehicles more appealing, practical, and accessible to a wider range of consumers and businesses. As research and development continue, we can anticipate further breakthroughs that will continue to shape the future of electric mobility and the benefits that come with driving an electric vehicle.
