Basic structure of square batteryA typical square lithium-ion battery consists of essential components such as a top cover, housing, positive and negative plates, laminated or wound separators, insulation components, safety components, etc. Among them, the two in the red circle are safety structu...

3C lithium-ion battery manufacturers interpret the 3C lithium-ion battery certification process and application areas. CCC certification is a mandatory legal safety certification and a basic practice widely adopted internationally to protect consumer rights and safeguard their personal and property...

According to the Decision of the State Council on Adjusting the Catalogue of Industrial Product Production License Management and Trial Simplifying the Approval Procedure (Guofa (2017) No. 34), electric bicycle products will be transferred from production license management to mandatory product cert...

Nowadays, most countries and regions in the world require products related to safety, health, environmental protection, and other projects to obtain safety certification before entering the market. The UL mark has become one of the world-renowned safety certification marks.The UL certification testi...

The production process of lithium batteries can be divided into three stages: front-end electrode manufacturing, back-end cell packaging, and back-end battery activation. The purpose of the battery activation stage is to fully activate the active substances and electrolyte in the battery to achieve...

According to reports, a recent study conducted by Stanford University in the United States on the behavior of tiny particles in lithium-ion battery electrodes showed that the damage to the battery caused by fast charging and then using it for high-power rapid power consumption may not be as bad as r...

Users of digital products have found that over time, battery capacity will inevitably decrease. Although the battery life was good when it was first purchased, after 2 years of frequent charging and discharging, it is completely different. The good news is that scientists from the US Department of E...

Aging test for lithium-ion batteriesNowadays, all new energy concept products such as new energy vehicles and new energy robots use new energy lithium-ion battery cells to form high-capacity lithium-ion batteries. So, what are the technical specifications for these lithium-ion batteries? We understa...

Aging of lithium-ion batteriesAging generally refers to the placement of batteries after the first charge after assembly, which can be room temperature aging or high temperature aging. All functions are aimed at stabilizing the performance and composition of the SEI film formed after initial chargin...
