Cylindrical 4695 High-Power Cell
Lishen 200EF
Cylindrical 4695 cell delivering 20 Ah capacity with 160 Wh/kg energy density and 60 A maximum discharge rate.
Overview
The Lishen 200EF is a high-power lithium-ion cylindrical 4695 cell designed for applications that demand both sustained high current and high energy density. Released in 2020 and with the manufacturer based in China, this cylindrical 4695 cell delivers 20 Ah capacity and 64.0 Wh of energy at a nominal voltage of 3.2 V, with a maximum continuous discharge capability of 60 A, making it well suited to high-power systems operating under aggressive discharge profiles. The 200EF stands out within the 20 Ah class by pairing a competitive energy density of 160 Wh/kg with the 3.0 C discharge rate more commonly associated with lower-capacity power cells in the Voltt library.

Motorsports
McMurtry Automotive: Faster cell evaluation
McMurtry Automotive used The Voltt and validated cell models to evaluate the transition from the Molicel P45B to P50B during early pack concept development.
Side by side modelling enabled rapid comparison of electrical and thermal behaviour, avoiding lengthy physical test campaigns. This approach reduced cell evaluation time by seven months, allowing the team to lock in cell selection and pack assumptions earlier while lowering technical risk and accelerating vehicle development.

Manufacturer Background
Lishen
Lishen is a Chinese state-backed lithium-ion cell manufacturer
Tianjin Lishen Battery was incorporated in 1997 and was China's first dedicated lithium-ion cell research and manufacturing company, now operating as a state-holding enterprise. It produces cylindrical, prismatic and pouch cells across lithium iron phosphate and nickel-based chemistries, supplying electric vehicles, stationary energy storage, consumer electronics and industrial equipment. Its large-format prismatic cells are aimed at grid-scale storage and commercial vehicle programmes, where cycle life and cost per kilowatt hour govern selection. State backing and long-established capacity give it stable supply for domestic manufacturers and export customers. Lishen's relevance lies in its production record, which is among the longest of any Chinese cell manufacturer.
