This batch of products has been graded. (Battery grading refers to the process of testing and grading batteries based on their capacity to ensure it meets the nominal value, and grouping batteries with similar capacities. This process typically takes place after the battery production is completed.)

Why is grading necessary?

1. Ensure Consistency
   There are inevitable differences in batteries during production. Matching helps select batteries with similar capacities, ensuring consistent performance when used together and preventing performance issues due to capacity differences.

2. Enhance Safety
   During the matching process, parameters such as voltage and internal resistance are checked, helping to identify potential issues, prevent substandard batteries from entering the market, and reduce safety risks.

3. Optimize Performance
   Using batteries with similar capacities together improves the charging and discharging efficiency of the battery pack and extends its service life.

4. Meet Customer Requirements
   Different applications have varying capacity requirements. Matching can provide the appropriate products according to these specific needs.

Battery grading is a crucial step in ensuring battery performance and safety. By screening and categorizing, it enhances the overall performance and reliability of the battery pack.

Many customers asked me, what is the difference between EVE and CATL? Which one is better? Here, I will give you a detailed answer.

From a technical point of view

CATL

CATL's LiFePO4 batteries offer slightly higher energy density compared to EVE and are known for their long cycle life and excellent thermal stability. They are widely used in demanding applications like large-scale energy storage systems and electric vehicles (EVs). With a mature thermal management system, they effectively prevent overheating and thermal runaway, making them ideal for long-term use in homes and EVs.

In energy storage, CATL's LiFePO4 batteries are extensively used in residential and commercial systems and have been widely validated in international markets. They offer strong durability and long service life (up to 15 years or more).

EVE Energy

EVE's LiFePO4 battery technology is also highly mature, with investments in emerging fields such as ternary lithium, solid-state, and sodium-ion batteries. They offer a range of energy storage batteries suitable for different-sized residential systems. Their A+ grade batteries ensure longer cycle life and stable performance (though it's important to watch out for counterfeit B-grade batteries in the market).

Market performance

CATL

CATL is the world's largest lithium battery manufacturer, with a global battery market share of 37.9% in 2024 and energy storage installed capacity ranking first in the world for many consecutive years.

CATL has long-term cooperation with leading companies such as State Grid, Tesla, BMW, and Volkswagen, and its energy storage systems have been applied to multiple benchmark projects, etc., and well-known automobile brands.

EVE

Focus on large-capacity battery cells and industrial and commercial energy storage markets to avoid direct confrontation with CATL on the grid side.

Although EVE is relatively small in the global battery market, its batteries have a good reputation in many industries and have a certain share in the European and Chinese domestic markets. In particular, it performs well in home energy storage systems and some power tool batteries.

Target Audience:

If you are interested in the world's leading battery technology, especially in the field of EV and high-end energy storage. Users with high requirements for performance, reliability and brand, especially large-scale home energy storage systems, CATL will be a better choice.

If you are pursuing high-quality batteries in the fields of small and medium-sized home energy storage, small solar systems, power tools, etc., EVE may be more in line with your needs.

Now let’s get back to CATL itself.

According to former Tesla battery supply chain manager Vivas Kumar, CATL "are seen as the leaders of lithium iron phosphate battery  (LFP battery) technology".
