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.
