This progression illustrates how EVE has developed from a primary lithium battery manufacturer into a company serving multiple segments of the global battery industry.

2. Primary and Secondary Batteries: What Is the Difference?

EVE's product portfolio includes both primary batteries and rechargeable secondary batteries. Although both store and deliver electrical energy, they differ in how they are used and the applications they support.

[Primary Batteries — Designed for Long-Term, Non-Rechargeable Use]

Primary batteries are designed for use until their stored energy is depleted. They are not intended to be recharged during normal operation.

EVE's primary lithium battery portfolio includes lithium-thionyl chloride (Li-SOCl₂) and lithium-manganese dioxide (Li-MnO₂) batteries, as well as specialized battery and capacitor solutions.

These batteries are suited to applications where long service life, low self-discharge, and reliable operation are important.

Typical applications include:

- Smart meters and utility metering equipment

- Industrial monitoring and sensing devices

- Security and alarm systems

- Internet of Things (IoT) devices

- Equipment requiring long-term, low-maintenance power

For example, lithium-thionyl chloride batteries are commonly used in applications requiring long operating life and stable power delivery.

[ Secondary Batteries — Designed for Repeated Charging and Discharging]

Secondary batteries can be recharged and reused over multiple charge-discharge cycles.

EVE's rechargeable battery portfolio includes small lithium-ion batteries, cylindrical cells, prismatic cells, pouch cells, and battery systems.

Depending on the cell chemistry and design, these products can support applications requiring different combinations of energy capacity, power output, cycle life, and charging performance.

Typical applications include:

- Consumer electronics and wearable devices

- Power tools and outdoor power equipment

- Electric two-wheelers and other mobility applications

- Electric vehicles

- Industrial equipment

- Energy storage systems (ESS)

The choice between a primary and a secondary battery depends on the application's operating pattern, maintenance requirements, energy demand, and expected service life.

3. EVE Energy's Major Product Categories

EVE's portfolio extends beyond a single battery chemistry or cell format. Its products can be broadly organized into consumer batteries, power batteries, and energy storage solutions.

 ① Primary Lithium Batteries

EVE supplies primary lithium batteries for applications requiring long service life and reliable operation.

Its product range includes Li-SOCl₂ and Li-MnO₂ batteries, with different cell formats and specifications available for various equipment requirements.

These batteries are particularly relevant to industrial electronics, metering, sensing, and other applications where battery replacement may be difficult or infrequent.

② Small Lithium-Ion and Cylindrical Cells

EVE also manufactures rechargeable lithium-ion batteries for consumer electronics, power tools, and other portable equipment.

Its cylindrical cell portfolio includes formats such as 18650 and 21700, with different models designed to meet varying capacity and discharge requirements.

The appropriate cell depends on the intended application, including available installation space, required runtime, operating current, charging conditions, and cycle life.

③ Prismatic LFP Cells

Lithium iron phosphate (LFP) batteries are an important part of EVE's rechargeable battery portfolio.

EVE's prismatic LFP product range includes models such as LF105, LF100LA, LF230, LF304, MB31, LF235L, and LF356L, as listed in its European product catalog.

These cells are relevant to applications such as energy storage systems, industrial power systems, and other battery packs requiring suitable combinations of capacity, service life, and system-level performance.

However, individual models differ in dimensions, capacity, electrical characteristics, and intended applications. Selection should therefore be based on the specific product datasheet and system requirements.

④ NCM and Other Power Battery Cells

In addition to LFP, EVE offers nickel-cobalt-manganese (NCM) lithium-ion cells in prismatic, pouch, and cylindrical formats.

These product categories support different design requirements across automotive, mobility, and other power applications.

The choice between LFP and NCM depends on the complete application design, including energy density, safety requirements, operating conditions, cycle life, cost, and pack architecture.

Neither chemistry is universally suitable for every application.

⑤ Large Cylindrical Cells and Energy Storage Systems

EVE has also expanded its activities in large cylindrical batteries and large-capacity energy storage cells.

In the energy storage sector, the company has developed large-capacity cells intended to help reduce the number of cells and simplify battery pack and system integration.

EVE announced the production launch of its 60 GWh energy storage battery manufacturing project in December 2024.

The announcement also introduced its 628 Ah large-capacity energy storage cell, known as Mr. Big.

These developments reflect the industry's broader move toward larger cells and more integrated battery systems for stationary energy storage.

4. Where Is EVE Energy Today?

EVE Energy's current business covers several connected areas of the battery value chain.

Its portfolio includes primary lithium batteries, rechargeable consumer batteries, cylindrical cells, prismatic LFP and NCM cells, pouch cells, large cylindrical batteries, and energy storage solutions.

This breadth allows the company to address different market requirements, from low-power devices requiring long-term operation to high-capacity battery systems used in mobility and stationary energy storage.

As demand for electrification and energy storage continues to develop, cell selection is becoming increasingly application-specific.

Battery capacity alone is not enough to determine suitability. 

Voltage, continuous and peak discharge current, charging limits, temperature range, cycle life, physical dimensions, and safety requirements must all be considered when evaluating a battery for a particular product.

For battery pack developers and equipment manufacturers, reviewing the cell datasheet and confirming compatibility with the intended system are essential steps before final selection.

5. Selecting the Right EVE Cell for Your Application

EVE's wide product range provides options for applications with different power, capacity, and operating requirements. 

However, the best choice depends on the intended use rather than the manufacturer or cell format alone.

When evaluating a battery, it is important to consider:

- Required nominal voltage and capacity

- Continuous and peak discharge current

- Charging method and charging time

- Expected operating time and cycle life

- Operating temperature and environmental conditions

- Available installation space and mechanical constraints

- Required protection, monitoring, and certification

For primary batteries, long-term reliability and self-discharge characteristics may be particularly important. 

For rechargeable cells, charge-discharge performance, cycle life, and compatibility with the battery management system may be key considerations.

Checking these requirements early can help reduce design changes and improve the suitability of the selected cell for the final product.

Conclusion

EVE Energy has developed from a primary lithium battery manufacturer into a diversified battery company serving consumer electronics, industrial equipment, mobility, automotive, and energy storage markets.

Its product portfolio includes both non-rechargeable primary lithium batteries and rechargeable lithium-ion cells in multiple chemistries and formats.

As battery applications become increasingly diverse, selecting the right cell requires more than comparing capacity or dimensions. 

A comprehensive evaluation of electrical performance, operating conditions, service life, and system compatibility is essential.
