New Reliance Energy Cells in the Batemo Cell Explorer!
We’ve added two high-perfor­mance tabless 21700 cells from Reliance Energy — the RS40 and RS50.
⚡ RS40: 4.0 Ah | 227 Wh/kg | 2.38 kW/kg
⚡ RS50: 5.0 Ah | 274 Wh/kg | 2.55 kW/kg (new power density record!)

New Chemistry Pairing in the Batemo Cell Explorer!
We’ve added a unique LFP | HC (Lithium Iron Phosphate + Hard Carbon) cell to the Batemo Cell Explorer — combi­ning safety, durabi­lity, and high power.
Tested: BePowered-310 from @BeyonderAS (33 Ah, 1.35 kW/kg, 116 Wh/kg).
This pairing enables high-power, stable, and sustainable cell perfor­mance.

In power tool applications, battery cells must deliver high discharge currents, maintain thermal stabi­lity, and provide reliable runtime under deman­ding opera­ting conditions. Selec­ting the right cell is crucial to meeting these perfor­mance requi­re­ments.
Cells like the Molicel P50B, Highstar 50PS(B), BAK 45D(B), Tempower 40XG, and Ampace JP30-PI(C), reflect the innova­tion happe­ning in this space.
We highlight some of the nuances in our full post on LinkedIn, using insights from the Batemo Cell Explorer.

The Amprius SA03, featuring its cutting-edge patented SiCore™ anode, measured in with an energy density of 399 Wh/kg, matching almost exactly the 400 Wh/kg reported by the manufac­turer.
The SA03 now holds the record for highest energy density across all cells in the Batemo Cell Explorer!
The SiCore™ cells from Amprius that leverage a multi-layered silicon anode archi­tec­ture designed to overcome one of the biggest challenges in silicon-based cells: expan­sion stress.

Until now, we have developed over 130 physical Li-ion cell models with an array of chemis­tries ranging from NMC, NCA, and LFP cathodes to graphite, silicon, and LTO anodes.
We’re thrilled to announce that we have now released our first physical sodium-ion (Na-ion) cell model into the Batemo Cell Model Library! 

At the forefront of Na-ion techno­logy, the Farasis S35(B) pouch cell delivers an impres­sive energy density of 150 Wh/kg, nominal capacity of 34.3 Ah, and a power density of 807 W/kg making it one of the most advanced repre­sen­ta­tions of Na-ion cells under development for commer­cial use at the moment.

Intro­du­cing the Toshiba SCiBTM 2.9Ah, a compact prismatic format cell and a game-changer for various applications, as it boasts an impres­sive 2.91 kW/kg power density.
The LTO chemistry in this SCiBTM (Super Charge ion Battery) cell offers excel­lent thermal stabi­lity and chemical safety, reducing the risk of overhea­ting and fire hazards - an essen­tial charac­te­ristic for electric mobility and drone applications, for example.
As reported by Toshiba, the 2.9Ah cell can be charged from 0 to over 80% SOC in one minute. Designed for endurance, it also maintains over 80% of its initial capacity even after 40,000 cycles at high tempe­ra­tures and C-rates. This ensures relia­bi­lity and long-term perfor­mance without the degra­da­tion often seen in tradi­tional lithium-ion batte­ries (Source)

Given the urgent need for cells with ultra-low internal resis­tance for many appli­ca­tion scena­rios such as eVTOLs, electric two-wheelers and portable storage, we just integrated two new 21700 cells that boost the technical level of cylind­rical cells by adopting the innova­tive design of tabless current collec­tion:
The INR2170-45D(B) from BAK’s full-tab 2170 cell series checks in at 248 Wh/kg and 2.12 kW/kg, while the EVE Energy 21700 40PL is designed towards even more power: With 233 Wh/kg and 2.35 kW/kg, the 40PL extends the techno­logy front of 21700 cells in the Batemo Cell Explorer.
