Problem
Many government and commercial applications require high-performance batteries that offer both high energy density and long cycle life. Existing lithium-ion batteries often struggle to balance these requirements, leading to compromises in either performance or longevity. Additionally, slow charging times and poor low-temperature performance limit the usability of current battery technology in demanding environments.
Solution
Rincell manufactures Silicon-Graphite lithium-ion batteries in 18650 and 21700 cell formats, designed to deliver high energy density without sacrificing cycle life or charging speed. These batteries achieve an energy density exceeding 300 Wh/kg and 800 Wh/L, coupled with fast charging capabilities that allow for 0-80% charge in under 20 minutes. The Silicon-Graphite chemistry also enables extended cycle life, exceeding 800 cycles, and unmatched low-temperature performance, including discharge at -40ºC. Rincell's batteries aim to accelerate the electrification of high-impact carbon emission products by providing a secure and domestically manufactured energy storage solution.
Target Audience
Rincell's primary customers are government and commercial entities requiring high-performance batteries for applications such as electric vehicles, aerospace, and grid storage.
