Next-Generation EV Battery Technology: A Look at Our Next Energy, StoreDot, and Factorial

The race to create more efficient and sustainable electric vehicle (EV) batteries is heating up, with companies like Our Next Energy (ONE), StoreDot, and Factorial leading the charge. These innovators are pushing the boundaries of energy density, charging speeds, and safety in their quest to power the next generation of EVs.

Our Next Energy (ONE) is focused on extending the range of EVs with its breakthrough battery technologies. Their dual-chemistry battery, dubbed Gemini, combines two battery types within one system to maximize both energy density and safety. By addressing the issue of range anxiety, ONE’s technology could enable EVs to travel up to 600 miles on a single charge, a significant leap from current standards. In the last few months, a BMW iX fitted with a Gemini battery pack was able to drive 608 miles, compared to the standard range of up to 382 miles.

StoreDot is revolutionizing charging speeds with its Extreme Fast Charging (XFC) battery technology. The Israel-based company aims to solve one of the most significant pain points for EV owners—charging time. StoreDot's silicon-dominant batteries promise to charge up to 80% in just five minutes, a remarkable improvement over current lithium-ion batteries. This rapid charging capability could make EVs even more practical and accessible to a wider audience. With a test bed upcoming Polestar 5 prototype, the 77kWh battery pack charged at over 310kW and peaked at 370kW without relying on any proprietary charging hardware.

Factorial Energy is tackling the issue of battery safety and energy efficiency with its solid-state battery technology. Unlike traditional liquid-based lithium-ion batteries, solid-state batteries use a solid electrolyte, which increases energy density and reduces the risk of fires. Factorial’s proprietary electrolyte material, called Factorial Electrolyte System Technology (FEST™), is designed to enhance the performance of EV batteries while making them safer and more reliable. The increased energy density help push the maximum range the battery pack can produce. Their Solstice solid state battery is set to power upcoming Mercedes models, with Stellantis and Hyundai both having invested in Factorial, their technology could shape other brands as well

Addressing the Future of Battery Production

Current lithium-ion batteries rely heavily on rare earth metals, like lithium, cobalt, and nickel, which pose social and environmental challenges due to resource scarcity and the impact of mining. However, the future of battery production is shifting toward more sustainable alternatives. Innovations such as solid-state batteries and lithium iron phosphate (LFP) batteries are emerging, with the potential to reduce or eliminate the need for rare earth metals. Additionally, sodium-ion batteries offer a promising solution by using more abundant and environmentally friendly materials.

These advancements aim to create more ethical, eco-friendly battery technologies, paving the way for a cleaner and more sustainable EV future.

Maximising EV battery life

With the battery being the heart of any EV, what can you do to help keep it healthy

For many car owners, switching to an electric vehicle (EV) represents an entirely new driving experience, bringing along numerous questions and concerns. One of the most common worries is about the battery life of an electric car. How long will it last? How do you ensure it stays in good condition? And what about the horror stories of batteries dying out too soon?

The good news is that EV batteries are built to last, often as long as the car itself. Like the batteries in your phone or laptop, EV batteries do degrade over time, but they hold up remarkably well under normal conditions. Typically, after 200,000 miles of driving, an EV battery should still retain at least 70% of its original capacity. In fact, some Tesla Model S taxis operating from Gatwick Airport have logged over 300,000 miles in just three years, with their batteries retaining more than 82% of their capacity.

Despite some alarming stories, the reality is that EV batteries are designed to endure, and with proper care, they can last for many years without significant degradation. Electric vehicle (EV) batteries have both gross and net battery capacities, which are terms used to describe the total amount of energy the battery can store and the amount of that energy that is actually usable for driving the vehicle. it's important to understand the difference between gross and net battery capacities. Gross capacity refers to the total energy the battery can store, while net capacity is the portion that’s actually usable for driving. Manufacturers intentionally reserve some of the battery's total capacity as a buffer to prevent deep discharges and overcharging, which can degrade the battery over time. This protective measure helps extend the battery's lifespan and maintain its performance, ensuring your EV runs efficiently for longer. Some car makers will allow the BMS (Battery Management System) to adjust the reserves in the gross capacity to be used as the battery ages

Battery degradation happens naturally over time and with use. Factors like frequent charging, discharging, and exposure to extreme temperatures can all contribute to the decline in efficiency. For instance, rapid charging generates higher temperatures, which can cause wear on the lithium-ion cells. This is why manufacturers recommend charging to 80% rather than to 100% and avoiding deep discharges where possible. The environment plays a role too. Hotter climates can lead to a subtle yet noticeable reduction in battery performance compared to cooler regions.

Fortunately, there are ways to preserve your EV’s battery life:

Smart Charging: Avoid letting your battery drop below 20% and charge only up to 80% to reduce heat build-up. Most modern EVs allow you to set these limits, ensuring you protect the battery even when you're not actively thinking about it.

Avoid Rapid Charging When Possible: While DC rapid chargers are convenient for quick top-ups, using them sparingly will help maintain your battery's longevity by reducing the number of high-heat cycles the cells undergo.

Temperature Management: In extreme weather, keep your car plugged in to allow the thermal management system to maintain an optimal temperature for the battery.

Drive Conservatively: Aggressive driving and frequent use of an EV’s instant torque can accelerate battery wear. By driving more gently, you can help keep the battery cooler and extend its life.

Charging at Home - The Lemac Power Advantage.

Having a reliable home charger, like those from Lemac Power, can make a significant difference in maintaining your EV battery’s health. Home chargers allow you to easily manage charging schedules, ensuring you don’t exceed the recommended 80% charge level. Plus, with a Lemac Power charger, you can take advantage of overnight charging at lower electricity rates, further reducing the stress on your battery and extending its life.

While EV batteries do degrade over time, with the right care and precautions, they can last as long as your vehicle does. By following the tips outlined above and using a high-quality home charger like those from Lemac Power, you can keep your battery in peak condition for years to come.
