Lithiumbatterien are more popular than ever, appearing in various electronics. However, not all lithium batteries are alike. Today, let’s explore the six main types of lithium batteries – their pros and cons, and their best applications.
Lithium Iron Phosphate (LFP)
LFP batteries are among the best types for energy storage systems. They feature phosphate cathodes and graphitic carbon anodes. These batteries boast long life cycles, excellent thermal stability, and reliable electrochemical performance.
Vorteile
LFP batteries are popular for high-power applications due to their durability, long lifespan, and safety. They often last over 2, 000 cycles, and depth of discharge minimally impacts their lifespan.
LFP batteries are typically rated for 80% depth of discharge, and some can even withstand 100% discharge without damage.
With low internal resistance and a thermisches Durchgehen threshold of around 270°C (518°F), LFP batteries are one of the safest lithium battery options.
Nachteile
LFP batteries have lower specific energy (90–120Wh/kg) compared to other lithium batteries, also the performance will be reduced performance in low temperatures. These make them less suitable for high cranking applications.
Anwendungen
LFP battery is often used to replace lead-acid deep-cycle batteries, as four cells in series produce 12. 80V, similar to six 2V lead-acid cells.
Lithium Cobalt Oxide (LCO)
LCO were an early Li-ion battery chemistry. They have high energy density but low power density, making them unsuitable for high-load applications. However, they can provide power over an extended period.
Vorteile
LCO batteries have high specific energy (150–200Wh/kg), allowing them to provide power for an extended period in low-load applications.
Nachteile
LCO batteries have a short lifespan of 500-1, 000 cycles, and cobalt is expensive, making them costly. LCO batteries also have low thermal stability, limiting their use in high-load applications.
Anwendungen
LCO batteries were common in lightweight and small electronics but are losing popularity due to high cobalt costs and safety issues.
Lithium-Ion Manganese Oxide (LMO)
LMO batteries use lithium manganese oxide cathodes, which improve ion flow, lower resistance, and increase current handling. This enhances thermal stability and safety.
Vorteile
LMO batteries charge quickly, provide high power (100–150Wh/kg), and operate efficiently at higher temperatures. They also offer flexibility, as their internal chemistry can be tuned to optimize for high-load or long-life applications.
Nachteile
LMO batteries are losing popularity as they offer the same characteristics as LFP batteries but have fewer life cycles, often only 300-700.
Anwendungen
LMO batteries are used for portable power tools, medical devices, and some hybrid/electric vehicles.
Lithium Nickel Manganese Cobalt (NMC)
NMC-Batterien balance nickel, manganese, and cobalt to harness their strengths. Nickel provides high energy density but is unstable, while manganese is stable but has low energy density. Combining these elements results in a stable, high-energy density battery chemistry (150–220Wh/kg).
Vorteile
NMC batteries have several advantages: high energy density, longer lifespan, lower cost than cobalt-based batteries and higher thermal stability than LCO batteries.
Nachteile
NMC batteries have a slightly lower voltage than cobalt-based batteries..
Anwendungen
NMC batteries, like LMO batteries, are popular in power tools and electronic powertrains for e-bikes, scooters, and some electric vehicles.
Lithium Nickel Cobalt Aluminum Oxide (NCA)
NCA batteries have higher energy density (200-260Wh/kg) than NMC batteries, allowing them to store more energy per unit volume. However, they are also more prone to thermal runaway events.
Vorteile
NCA batteries have high energy density and reasonable lifespan.
Nachteile
NCA batteries are less safe and more expensive than other lithium batteries.
Anwendungen
NCA batteries are popular in the electric vehicle market due to their ability to perform in high-load applications with long battery life. Tesla uses NCA batteries.
Lithium Titanate Oxide (LTO)
LTO batteries are very safe and long-lasting, with faster charging than other lithium batteries. They use lithium titanate in the anode and LMO or NMC in the cathode.
Vorteile
LTO batteries offer fast charging, a wide operating temperature range, high lifespan up to 10,000 cycles, and excellent safety due to their stability.
Nachteile
LTO batteries have lower energy density (50–80Wh/kg) than all other 5 types of lithium batteries. They are also very expensive.
Anwendungen
LTO batteries have numerous applications, including electric vehicles, charging stations, telecommunications, and aerospace/military equipment.
What’s The Most Common Type of Lithium Battery?
LCO batteries power cell phones, laptops, tablets, and digital cameras – making them the most common type of lithium battery.
