Nanograf in the US has developed a cylindrical lithium-ion cell with an energy density of 800Wh/l using a silicon battery anode. The 18650 format cylindrical lithium-ion cell with a silicon anode developed by Nanograf provides 3.8Ah, 28 percent more power that graphite-based anode...

The 18650 LiPo battery manager comes with a fuel gauge and a dual-rail power supply. The dual-rail power provides a 5V rail along with a 3.3V rail dedicated to powering the microcontroller and the display ports of the system. It is termed as an “all-in-one single-cell LiPo battery...

Nanotech Energy Inc. announced that beginning in the first quarter of 2021, the company will mass produce non-flammable, efficient, and fast-charging lithium-ion 18650 Batteries. These cell-type batteries are used in devices including, but not limited to, laptop computers, cordless...

This small board is based on the CS5171 boost converter from ON Semiconductor. The board is configured to be used with a single 18650 LiPo battery. The circuit converts single-cell 3.7V LiPo battery voltage to 5V with a load current up to 400mA. Board has been designed to fit on the...

peter6960 shared a new project. It' s about a 18650 cells power brick with onboard battery management system. He writes: While I cannot afford a Tesla PowerWall, I’ve spent some time drawing up a PCB to house 7x 18650 cells in series. Each board has onboard Battery Management:...

Adam Bender writes: Designing a custom lithium battery pack is a fun way to learn about electricity and engineering. Lithium batteries can be used for countless applications including electric bikes, scooters, vehicles, backup power suppliers, off the grid solutions, and much more....
