I want to know a solution of ncm graphite full cell ?

03 January 2025 0 1K Report

I make ncm622/graphite full cell (0.05C / 3~4.3V)

My full cell has an OCV of 40 mV. Additionally, the first cycle's Coulombic efficiency is significantly low. During the first charge, the cell already achieves a capacity of nearly 40 mAh/g around 3V.

The conditions for my full cell are as follows:

NCM622: Super P: PVDF = 80:10:10 wt% Graphite: Super P: PVDF = 80:10:10 wt%

NCM622 electrode: 11 mg/cm² Graphite electrode: 14 mg/cm²

Electrolyte: 1 M LiPF6 in EC:EMC (3:7 v/v)
