BATTERY TECHNOLOGIES & TYPES COMPARED | VOGT CTE

Batteries store electrical energy in chemical form and release it when needed. Depending on their design, materials, and chemical systems, they vary significantly in energy density, weight, safety, lifespan, and thermal behavior. Currently, lithium-ion batteries are widespread, while new types of batteries are being developed to become safest, lighter, more efficient, or more sustainable. A fundamental understanding of the different battery types is crucial for properly assessing their applications, risks, and safety and disposal requirements.

A BRIEF OVERVIEW OF THE MOST IMPORTANT CRITERIA REGARDING BATTERIES

  • Energy Density: The amount of energy that can be stored per volume or weight. High = long runtime or range.
  • Self-Discharge: The amount of energy lost without use. Low = good for long storage.
  • Weight: Important for mobile applications like vehicles or devices.
  • Hazard: Risk of fire, explosion, or toxic gases in case of failure.
  • Extinguishability: How well fires can be controlled or extinguished.

BRIEF SUMMARY OF BATTERY TECHNOLOGIES

  • Lithium-ion batteries provide high performance but are safety-critical.
  • LFP and LTO are safer but less energy-dense.
  • Sodium-ion batteries are considered promising, more affordable, and safer alternatives.
  • Solid-state batteries could potentially combine high energy density with significantly improved safety.
  • Redox flow batteries are very safe but suitable only for stationary applications.
  • The higher the energy density of a battery, the greater the requirements for safety, cooling, and fire control are typically.

ASSESSMENT OF MARKET TRENDS

Over the next ten years, the battery market will undergo significant development, with lithium-ion batteries continuing to play a central role while solid-state batteries will gradually join them without displacing lithium-ion batteries in the short term.

Lithium-ion batteries will remain the dominant battery technology for the foreseeable future. They are now industrially mature, relatively cost-effective, and available in massive quantities. Their market growth is primarily driven by electric mobility, stationary energy storage, e-bikes, and the overall electrification of industry and infrastructure. In the coming years, lithium-ion batteries will continue to improve, for example through safer cell chemistries like LFP, longer lifespan, lower costs, and optimized production processes. Recycling and second-use are also gaining importance. Despite known risks such as fire hazards, lithium-ion technology remains the mass standard due to its established supply chains and economic viability—especially well beyond 2030.

In contrast, solid-state batteries are seen as a future technology with significant potential, but they are still transitioning from research to industrial mass production. Their main advantage is increased safety, as they do not contain a liquid electrolyte, along with the prospects of higher energy densities and faster charging times. In the next few years, initial applications are expected, initially in niche and premium segments, such as high-quality electric vehicles or specialized applications. However, market ramp-up will occur more slowly than often perceived publicly, as production is technically complex, costly, and difficult to scale.

From around 2030, we can expect a growing market penetration of solid-state batteries, although more as a complement than a replacement. Lithium-ion batteries will continue to make up the largest share of the overall market, while solid-state batteries will be primarily used where safety, energy density, or lifespan are particularly critical. This results in no abrupt technology-switch scenario in the long term, but rather a coexistence of different battery types that are each optimized for various requirements.

In summary, it can be said that lithium-ion batteries will remain the backbone of the global battery market over the next ten years, while solid-state batteries will gradually establish themselves as an important complement. The change is evolutionary, not revolutionary.

WHAT ARE THE IMPORTANT AND DANGEROUS ASPECTS OF HANDLING THE VARIOUS TYPES OF BATTERIES?

The safe handling of batteries strongly depends on the specific chemical battery type. Each type carries its own risks, typical sources of error, and requires specific safety measures. An overview helps realistically assess hazards and act correctly in the event of an emergency.

Lead-Acid Batteries
Important: They are robust and manageable, but require regular maintenance and good ventilation.

  • They contain corrosive sulfuric acid, which poses a danger to skin and eyes.
  • During charging, they can produce explosive gas (hydrogen), creating a risk of explosion in closed spaces.


They are very heavy, which poses a risk of injury during transport.

Nickel-Metal Hydride (NiMH):
Important: Relatively safe but sensitive to improper charging.

  • Overcharging can lead to overheating and gas production.
  • Due to higher self-discharge, they are often stored in a deep-discharged state.


Leakage is possible in case of a defect, but fire incidents are rare.

Lithium-Ion (traditional: NMC, NCA)
Important: High energy density requires battery management, cooling, and protection circuits.

  • Thermal runaway can occur with overcharging, short circuits, or mechanical damage.
  • Very high fire temperatures are generated.
  • Re-ignition can occur hours or days after a fire.


Toxic and flammable gases are released.
→ Lithium-ion batteries are among the most critical battery types in the event of a fire.

Lithium Iron Phosphate (LFP)
Important: Much more stable than traditional lithium-ion batteries.

  • Lower, but existing fire risk.
  • Strong heat and smoke development is also possible here.


A fire is slower but still difficult to extinguish.


Lithium Titanate (LTO)
Important: very safe lithium type with long lifespan and fast charging capability.

  • Significantly lower risk.
  • The fire risk is low but not zero.


Critical only in case of severe damage.


Sodium-Ion Batteries:
Important: Similar structure to lithium-ion batteries, but less energy-dense.

  • Lower fire intensity than lithium-ion batteries.
  • The technology is still young, so long-term experiences are lacking.


In the event of a fire, heat and smoke development can still occur.


Solid-State Batteries (future)
Important: No liquid electrolyte, making them fundamentally safer.

  • Limited practical experience so far.
  • Potential risks are more mechanical or material-related.


The fire hazard is significantly reduced.


Lithium-Sulfur Batteries (future)
Important: Very high energy density, but still in development.

  • Chemically reactive.
  • Ageing and instability are currently problematic.

The fire and safety behavior is not yet fully clarified.


Redox-Flow Batteries
Important: They are very safe in case of fire and well-suited for stationary storage.

  • Chemical liquids (some toxic or corrosive).
  • Leaks are the main problem, not fire.


There is little fire risk, but an escape of liquids presents environmental hazards.


Summary
The highest fire risk exists with conventional lithium-ion batteries. The safest lithium types are: LFP, LTO. Chemical hazard instead of fire: lead-acid, redox-flow. The future promises greater safety through new materials and solid-state systems. The higher the energy density, the more critical the handling, cooling, and fire protection—safety begins long before a fire occurs.

ASSESSMENT OF THE LATEST BATTERY TECHNOLOGIES

Flow, salt, and graphene batteries are not considered direct successors to lithium-ion batteries, but rather as complementary specialized technologies that are useful in certain applications.

Flow batteries are already market-ready today, but are almost exclusively suitable for stationary large-scale storage. They are very safe, virtually fireproof, and can withstand extremely many charge cycles. However, they are large, heavy, and have a low energy density. They are becoming increasingly important for grids, wind, and solar facilities and will play a larger role now and increasingly until 2030, though not in mobile applications.

Salt batteries are thermally very stable, safe, and utilize readily available raw materials. Their energy density is lower than that of lithium-ion batteries, which is why they are primarily suitable for stationary storage in buildings, neighborhoods, and industrial facilities. They are still niche products today, but could gain significance around 2030, as safety and sustainability become more important than maximum performance.

Graphene batteries are currently primarily a development technology. Graphene is already used as an additive to make lithium-ion batteries charge faster and last longer. A true graphene battery as a standalone replacement is rather unlikely before 2035.

In short: Flow and salt batteries will become more important primarily in the stationary sector, while graphene will remain a improvement of existing batteries for the time being. The market is evolving more diversely, not through a single technological shift.
