Large Lithium Battery cell sizes potentially coming in 2025

Based on the report from Intersolar Europe 2024, here are the energy storage cells announced to be coming in the near future.

1. 300Ah+ Cells:
   • Various manufacturers are focusing on 300Ah+ cells, including capacities like 305Ah, 306Ah, 314Ah, 315Ah, 320Ah, 345Ah, and 350Ah.
   • Prominent manufacturers like EVE Energy, REPT and Hithium displayed 306Ah and 314Ah cells, with many already certified for non-China markets.
2. 500Ah+ Cells:
   • Most major LFP manufacturers have exhibited large-capacity cells, with capacities ranging from 580Ah-1130ah respectively.
   • These 500Ah+ cells are expected to enter non-China markets by the first half of 2025.
3. 1100ah Mega Cells – Hithium 1130ah, more to follow
4. 5 MWh- 7MWh+ Energy Storage Systems (BESS): 20FT Containers
5. Companies like CATL and BYD are developing 5, 6 and 7 MWh+ energy storage containers and systems, with 5 MWh+ systems likely to expand into non-China markets in 2025.

These cells and systems showcase the trend towards higher capacity and energy-efficient solutions in the energy storage industry. The article emphasizes the growth of larger-capacity cells (300Ah+ and 500Ah+), which will play a significant role in upcoming storage solutions across the globe.

The Growing Importance of Energy Storage

In the next 30 years, the energy storage industry is expected to experience explosive growth. Industry leaders predict that in 2024 alone, new energy storage capacities will exceed 180GWh. However, with this growth comes increased competition and industry consolidation, as companies with advanced technologies, robust supply chains, and strong brands are better positioned to thrive.

For REPT, which was the first to mass-produce 320Ah energy storage cells in 2023, maintaining technological leadership is key. The release of its new 587Ah and 625Ah cells marks the next step in its efforts to stay ahead in the competitive market.

As all of these manufacturers jostle, they must strive for longer lifespans, better energy efficiency and lighter batteries. All of these factors are important to the future of the World and its Energy needs as it moves away from fossil fuel and into the renewables age.

CATL
In December of last year, CATL began constructing a new production line for its 530Ah energy storage cells. According to industry experts, while the length of these 530Ah cells is extended, their width and thickness remain unchanged, enabling the reuse of the 280Ah production line equipment. The L-series battery cells in CATL’s Tianhang energy storage system boast an energy density of 430Wh/L, with single-cell capacities estimated to be at least 587Ah based on current data.

NARADA
On April 11, NARADA introduced a 690Ah high-capacity energy storage battery with an impressive lifespan of 20 years. Its volume energy density ranges from 380-440Wh/L, with a cycle life reaching up to 15,000 cycles. Each battery delivers more than 2kWh of energy, operating with over 96% efficiency. This battery is compatible with capacities ranging from 650Ah to 750Ah. A 20-foot energy storage system outfitted with this battery can achieve a capacity of 6MWh.

VISION
In May 2023, VISION launched its 580Ah energy storage battery, offering 1.856kWh of energy per cell with a weight of 11kg and a cycle life of 10,000 cycles. The company is planning to establish a 5GWh production base for these cells in Hubei.

ETC
Targeting the long-duration energy storage market (4-8 hours), ETC has developed a 630Ah energy storage battery capable of storing 2016Wh of energy per cell. These batteries offer a cycle life of over 10,000 cycles and an energy efficiency of more than 96%.

EVE
EVE became the first company in China to release 500+Ah battery cells back in October 2022 with its 560Ah LF560K energy storage battery. In August 2023, they introduced a new large laminated smart cell, the LF560K “Mr. Big,” with a capacity of 628Ah, delivering 2.009kWh per cell and a cycle life of 12,000 cycles. Earlier this year, the company announced its 628Ah “Mr. Big” technical route and the 5MWh “Mr. Giant” energy storage system. Production of the LF560K is planned at EVE’s Jingmen base, with an expected capacity of 60GWh. The first phase of the factory is anticipated to be operational by Q2, with full production starting by the end of the year.

TrinaStorage
TrinaStorage recently revealed the successful development of its 500Ah+ high-capacity batteries. According to the company’s director, the 500Ah+ battery represents a major innovation, striking a balance between performance and cost. This design, based on accumulated years of research in battery electrochemistry, optimizes the volume-specific energy density of the standard 20-foot battery compartment, resulting in a well-balanced solution.

HiTHIUM
HiTHIUM set a new industry benchmark with the world’s first long-term energy storage battery featuring a 1130Ah MIC capacity. This battery maintains over 60% SOH (State of Health), ensuring the energy storage system’s service life extends beyond 20 years.

SVOLT
SVOLT has released a 710Ah fly-stack short knife energy storage cell alongside a 660Ah long-life system cell. Recently, the company launched a 730Ah large-capacity short-knife battery, built upon the foundation of its L500-350Ah energy storage cell. This battery offers an energy density of 420Wh/L and a cycle life exceeding 11,000 cycles.

SUNWODA
SUNWODA has announced plans to release a 600+Ah battery program aimed at improving cell integration. This initiative will reduce PACK components by 40%, reinforce the cell structure, and make PACK platforms more adaptable and easier to modify.
