18650 Battery Leaking: Causes, Warning Signs and Safe Response

Stop using or charging a leaking 18650 cell. Visible leakage, damage, swelling or unusual heat needs attention. Do not open, recharge or attempt to repair the cell. If it is hot, smoking or showing signs of immediate danger, keep away and contact the relevant emergency service. For an OEM or device maker, the next technical […]
Lithium vs. Sodium Batteries: Which Technology Fits Your Energy Strategy?

Choose between lithium-ion and sodium-ion batteries by comparing actual models against the same load, space, temperature and charging requirements. Sodium availability alone does not prove a lower pack price, and neither chemistry provides a blanket safety guarantee. Start with the requirements your system must meet. Sodium Battery vs. Lithium Battery: An Overview Lithium-ion covers several […]
18650 vs. Lithium-Polymer Cells: Format, Protection and Fit

An 18650 designation mainly describes a cylindrical cell format. Lithium-polymer or LiPo is used for particular polymer-based cell designs and, commercially, often for pouch cells. These labels are not equivalent classifications of chemistry or safety, and a pouch labeled LiPo is not automatically a solid-state battery. For selection, compare actual cell models using the device […]
