LITHIUM BATTERIES.  LOCAL ENERGY.

There are several types of lithium batteries, which are generally differentiated by the material used for the cathode (the positive electrode). The most common types are lithium-cobalt (LiCoO2), lithium-manganese (LiMn2O4), lithium-nickel-manganese-cobalt (NMC), lithium-nickel-cobalt-aluminum (NCA), and lithium-iron-phosphate (LiFePO4 or LFP) batteries. Volthium batteries are Iron Phosphate batteries known as LiFePO4 and LFP which are a kind of lithium ion battery. They differ from other types of lithium batteries in their use of iron phosphate for the cathode, rather than cobalt or nickel. They are attributed the following qualities:

• Safety and Stability: LFP batteries are recognized for their safety and superior thermal stability. Compared to other types of lithium batteries, they are less likely to overheat or catch fire if they malfunction or are misused. This increased safety is due to the intrinsic stability of iron phosphate.
• Durability and Cycle Life: LFP batteries also have a long cycle life and can maintain high charge capacity even after many charge and discharge cycles. They have a low self-discharge rate , which means they can hold their charge for long periods without use.Our batteries offer more than 6000 cycles and have a lifespan of approximately 15 years.
• Environmental performance: Compared to other types of lithium batteries, LFP batteries have a potentially lower environmental impact. Iron is more abundant and less toxic than cobalt and nickel, and iron mining has less environmental impact. Also, LFP batteries are easier to recycle than other types of lithium batteries.

Decrease our dependence on fossil fuels, improve air quality, manage electronic waste more responsibly; lithium batteries have had a significant positive impact on the environment, playing a vital role in the transition to a cleaner and more sustainable society. Their increasing adoption in various fields, such as electric vehicles and renewable energy storage, has helped to significantly reduce greenhouse gas emissions from transportation and power generation. Compared to traditional battery technologies, lithium batteries have a significantly lower carbon footprint, helping to mitigate the impacts of climate change.

Recycling of lithium batteries has also become more efficient, allowing valuable materials such as lithium, cobalt, and nickel to be recovered and reused in new batteries or other applications.

The future of lithium batteries

The future of lithium batteries looks exciting as efforts to improve this essential technology are constantly evolving. Researchers and engineers are redoubling their efforts to meet the challenges and harness the potential of lithium batteries.

One of the most promising breakthroughs is in the development of solid-state batteries. Unlike traditional batteries that use liquid electrolytes, solid state batteries use solid electrolytes, making them safer, more efficient and longer lasting. These batteries offer higher energy density, allowing devices and vehicles to have longer range without increasing the size of the batteries. Additionally, solid state batteries are less sensitive to temperature changes, making them ideal for use in extreme environments such as in Canada.

Advanced recycling

Another key aspect of the future of lithium batteries is advanced recycling. As the demand for lithium batteries increases, it is crucial to have effective recycling methods in place to recover valuable materials and reduce the environmental impact of their manufacture and disposal. Advances in recycling technologies make it possible to recover metals such as lithium, cobalt, nickel and manganese from used batteries. These materials can then be reused in the manufacture of new batteries or in other industrial applications, thus helping to reduce the dependence on virgin materials.

Improved lithium extraction:

Greener and more efficient methods of lithium extraction are also being developed. This includes methods that require less water, produce less waste, or use alternative materials like lithium mined from seawater or geothermal sources.

Alternative cathode materials:

Researchers are also exploring the use of alternative materials for the cathode in lithium batteries, with the aim of reducing reliance on rare and expensive metals and improving battery efficiency and life.

Iron Phosphate (LiFePO4) batteries are types of lithium-ion batteries that use iron phosphate cathode materials. They are becoming increasingly popular due to their improved performance in safety, efficiency and durability compared to other types of lithium batteries. Here are the three most important facts about LiFePO4 batteries:

1. Increased safety: LiFePO4 batteries are known to be safer than other types of lithium batteries, such as lithium cobalt (LiCoO2) batteries. They are less prone to fire and explosion hazards, making them ideal for applications where safety is paramount. Insurance companies love them!

2. Durability: LiFePO4 batteries have a longer life compared to other types of lithium batteries, such as lithium nickel cobalt aluminum oxide (NCA) batteries. They can withstand a greater number of charge/discharge cycles, which makes them economically advantageous in the long term. Their profitability over the long term is ensured in particular by opting for the dynamic pricing of the electricity supplier in your region of residence.

3. Energy capacity and low self-discharge rate: LiFePO4 batteries can be discharged up to 100% without being damaged, they offer a much higher energy capacity than lead acid batteries, which can only be discharged up to 50% of their storage capacity.

They have a lower self-discharge rate compared to some other battery technologies. This means they hold their charge longer when not in use, which is handy for applications where power is used intermittently. Our batteries only lose an average of 3% charge per month of inactivity. It is still advisable to unplug them when the expected period of non-use is greater than 3 months.

LiFePO4 batteries offer several advantages over other types of lithium batteries. Here are the three main ones:

LiFePO4 batteries are used in a variety of applications due to their advantageous characteristics. Here are the main uses:

1. Recreational vehicles: LiFePO4 batteries are widely used as a power source in recreational vehicles and RVs due to their increased safety, and durability but above all the large energy capacity they offer in relation to the space occupied and their weight.

2. Nautical applications: We manufacture high quality house batteries, in order to provide all the energy necessary for sailboats and pleasure boats during getaways on the water. Our batteries meet all ABYC standards, in particular with the possibility of adding visual and audible alerts depending on the state of charge of the battery.

3. Energy storage systems: LiFePO4 batteries are also used to store energy produced by renewable sources such as solar and wind power. They allow excess electricity to be stored for later use when energy production is low. But they also make it possible to reduce the electricity bill considerably by practicing peak shaving. By opting for a hybrid system, you will be able to recharge your batteries during off-peak hours (at a preferential rate) and use the energy stored during peak hours (when your supplier’s rate is at its highest). This also allows you to maintain an interesting energy freedom, especially when there are power outages on the network.

4. Industrial Applications: Our LiFePO4 batteries are commonly used in a variety of industrial applications, including telecommunications backup systems, uninterruptible power supplies (UPS), ,power tools, but also for scientific projects in the far north or in extreme conditions.

When buying LiFePO4 batteries, it is essential to consider certain factors to ensure that you choose the right option. Here are the three key factors to consider:

• Capacity: The capacity of the battery, expressed in ampere-hours (Ah), determines the amount of energy it can store. It is crucial to choose a battery with the right capacity for the specific application to avoid premature discharge.
• Nominal voltage: The nominal voltage of the battery, expressed in volts (V), must be compatible with the requirements of the device or application in which it will be used. An unsuitable tension can damage the system .

Cycle Life: The number of charge/discharge cycles the battery can go through before losing a significant amount of capacity is critical.

To maximize the life of LiFePO4 batteries, proper maintenance is necessary. Here are the three essential maintenance tips:

1. Operating temperature: LiFePO4 Voltium batteries can be discharged at temperatures ideally between -35°C to 60°C. To avoid damaging the battery, it is best to recharge it at a temperature above 5°C, which is why we have developed a self-heating technology allowing the battery to be heated in extreme conditions up to 5°C before the BMS authorizes charging. Exposing and using the battery in extreme temperatures could affect performance and longevity.

2. Charge/discharge rate: Limit extreme charge and discharge rates, as this can stress the battery and shorten its lifespan. Choose moderate charge/discharge rates for optimal use.

3. Storage: When LiFePO4 batteries are not in use, store them in a cool, dry place at a charge of approximately 60% at 80%. This helps to reduce self-discharge and preserve their capacity
