Zhuhai Guanyu Battery Files Patent for Sodium Supplement Agent, Cathode Sheet, and Sodium-ion Battery with Enhanced Energy Density and Cycle Performance

Zhuhai Guanyu Battery Co., Ltd. applied for a patent named "Sodium Supplement Agent, Cathode Sheet, and Sodium-ion Battery" in March 2024, with the patent number CN202410336950.5.

According to the patent abstract, this invention relates to the field of batteries, particularly to a sodium supplement agent, which includes a cathode sheet of the sodium supplement agent and a sodium-ion battery including the sodium supplement agent. The sodium supplement agent includes sodium oxalate, with a median particle size Dv50 ranging from 0.01μm to 8μm. This sodium supplement agent has a high theoretical capacity and has no significant impact on the electrical performance of the sodium-ion battery, allowing the sodium-ion battery including the sodium supplement agent to have higher energy density and cycle performance.
