6 Types of Lithium Batteries Used in Electric Vehicles

An Overview of Different Types of Lithium Batteries

Our world has changed dramatically because of lithium batteries, which power everything from electric cars to cell phones. However, there are a variety of choices available in the lithium market, each with its own set of advantages and disadvantages.

In this blog, Renovar helps you to explore the six most prevalent types of lithium batteries.

Lithium Cobalt Oxide (LCO)

LiCoO2 cells have a low specific power but a high specific energy. This indicates that although they can supply electricity for an extended amount of time, they do not function effectively in high-load situations.

Characteristics of LCO

Cycle Life500 – 1000 cycles
Charge Rate0.7–1C to 4.20V (3h typical); avoid >1C.
Turn off when the current saturates at 0.05C.
Discharge RateMaintain 1C; cutoff at 2.50V.
Avoid >1C for prolonged battery life.
VoltagesNominal: 3.60 V; Operating range: 3.0 – 4.2 V/cell
Specific Energy150 – 200 Wh/kg

Source: Battery University

Benefits

  • High energy density (stores a lot of energy in a small space)
  • Long lifespan (can undergo many charge/discharge cycles)

Drawbacks

  • Expensive
  • Less stable (can overheat in extreme conditions)
  • Contains cobalt, raising ethical and environmental concerns

  • Early laptops and mobile phones (being phased out due to drawbacks)

Lithium Manganese Oxide (LMO)

Lithium manganese oxide is used as the cathode material in LiMn2O4 batteries. This chemical produces a three-dimensional structure that enhances thermal stability and safety, boosts current handling, decreases internal resistance and improves ion movement.

Characteristics of LMO

Cycle Life300 – 700 cycles
Charge Rate0.7–1C (3C max), up to 4.20V. Turn off at 0.05C saturation.
Discharge Rate1C (up to 10C, 30C pulse for 5s), cutoff at 2.50V.
VoltagesNominal: 3.70 V; Operating range: 3.0 – 4.2 V/cell
Specific Energy100 – 150 Wh/kg

Benefits

  • Good safety characteristics
  • Stable at high temperatures

Drawbacks

  • Lower energy density compared to LCO and NMC
  • Shorter lifespan

Lithium Nickel Manganese Cobalt Oxide (NMC)

The advantages of nickel, manganese, and cobalt – the three primary elements utilised in the cathode – are combined in LiNiMnCoO2 batteries.

Although nickel has a high specific energy on its own, it is not stable. Manganese has a low specific energy but is remarkably stable. A stable chemical with a high specific energy is produced when they are combined.

Characteristics of NMC

Cycle Life1000 – 2000 cycles
Charge Rate0.7–1C to 4.20V (some to 4.30V); 3h typical.
Avoid >1C for longer life. Turn off at 0.05C saturation.
Discharge Rate1C (2C possible on some); cutoff at 2.50V.
VoltagesNominal: 3.70 V; Operating range: 3.0 – 4.2 V/cell
Specific Energy150 – 220 Wh/kg

Source: Battery University

Benefits

  • High energy density (longer driving range for EVs)
  • Good overall performance

Drawbacks

  • Less safe compared to LFP
  • Shorter lifespan than LFP
  • More expensive than LFP

Lithium Iron Phosphate (LFP)

Phosphate serves as the cathode material in LiFePO4 batteries, while graphitic carbon electrodes serve as the anode. Long-lasting LFP batteries provide strong temperature stability and electrochemical performance.

Characteristics of LFP

Cycle Life2000 cycles
Charge Rate1C to 3.65V, 3h typical; turn off at 0.05C saturation.
Discharge Rate1C (25C possible on some); 40A pulse for 2s;
cutoff at 2.50V (avoid <2V to prevent damage).
VoltagesNominal: 3.30 V; Operating range: 2.5 – 3.65 V/cell
Specific Energy90 – 120 Wh/kg

Source: Battery University

Benefits

  • Excellent safety (most stable lithium chemistry)
  • Long lifespan (can last for thousands of cycles)
  • Affordable

Drawbacks

  • Lower energy density compared to NMC and NCA
  • Slower charging compared to some other lithium batteries

Lithium Nickel Cobalt Aluminum Oxide (NCA)

LiNiCoAlO2 batteries have a long lifespan, good specific energy, and reasonable specific power. Thus, they have a long-term capacity to deliver a sizable amount of current.

Characteristics of NCA

Cycle Life500 cycles
Charge Rate0.7C to 4.20V (3h typical); fast charge with some cells.
Turn off at 0.05C saturation.
Discharge Rate1C; cutoff at 3.00V. High discharge shortens battery life.
VoltagesNominal: 3.60 V; Operating range: 3.0 – 4.2 V/cell
Specific Energy200 – 260 Wh/kg

Benefits

  • High energy density (similar to NMC)
  • Good power output

Drawbacks

  • Less safe compared to LFP
  • Similar drawbacks to NMC regarding stability and cost

Lithium Titanate (LTO)

The cathode material’s chemical composition distinguishes each of the earlier lithium battery types we covered. Li2TiO3 batteries employ LMO or NMC as the cathode chemistry and substitute lithium titanate for graphite in the anode.

The end product is a long-lasting, incredibly safe battery that charges faster than any other lithium battery.

Characteristics of LTO
