Samsung Testing 12000mAh 18000mAh Batteries With Dual Cell and Triple Cell Designs Leaked Reports Show

Samsung is also said to be testing high-capacity silicon-carbon (Si-C) smartphone batteries, including 12,000mAh and 18,000mAh prototypes. A leaked document suggests that Samsung SDI is refining cell stacking designs and battery management software to improve reliability, thermal performance and efficiency. The company has been cautious about new battery technology since the Galaxy Note 7 incident in 2016 and is still reviewing Si-C batteries before launching them commercially. If development succeeds, thinner high-capacity cells could eventually power future flagship smartphones and foldable phones without increasing device thickness.

Samsung SDI Testing Next-Gen Silicon-Carbon Batteries for Phones

A user Schrödinger (@phonefuturist) posted the information on X about Silicon-carbon smartphone batteries, including 12,000mAh and 18,000mAh prototypes, which are being tested by the South Korean tech firm. It also states that a larger 20,000mAh silicon-carbon battery previously tested for durability testing following around 996 charge cycles, which was not tested by the post.

This allows for a higher capacity without significantly increasing battery size, with Silicon-carbon batteries having more energy than lithium-ion cells by using ‘anode’ instead of graphite (stylin) anodes. This technology has already been adopted by several newer smartphone models, especially from Chinese companies.

The 20,000mAh unit was designed to be a dual-cell model, which combined ‘12,000mAh primary cell measuring about 6″ (leaked testing details) according to the latest version of its test. Approximately 4mm thick with a secondary 8,000mAh cell, 3mm thickness and 1mm thin. While testing the prototype, it was reportedly not tested for Samsung’s durability targets and so the company continued to develop with smaller silicon-carbon battery configurations.

The One prototype reportedly has 12,000mAh of capacity and is dual-cell structure, with an estimated 6,800mAh cell that measures about 4 in size. 7mm and a 5,200mAh cell of about 3mm. 2mm. The combined thickness is less than 9 inches (about the intended thickness) of . Although some test samples were reportedly more than that limit, tests tested samples are said to have gone over 3mm (although s may be at least threemm).

Also, Samsung is also said to be testing an 18,000mAh configuration built from three cells rated at 6,699mAh, 6,000mAh and 5,257mAh thicknesses of about 4 inches. 2mm, 3mm. 9mm, and 3mm. respectively 28mm, and 28m. The thickness of target stacked is about 12 inches. Several prototypes have been reported to have had some of the more thermal interface layers between the cells, which is said to be about 12 times as they are believed to mean 3mm. 8mm paraphrasing

Although the development of 12,000mAh and 18,000mAh batteries is still ongoing, it has been claimed that the testing programme aims for an estimated lifespan of around 1,500 charge cycles for the test programme. According to the 12,000mAh model, it is said that its stability and theoretically could deliver about 20 to 25 hours of screen-on time on a smartphone connected to mobile data and Wi-Fi.
