China's CATL Reveals the First-generation Sodium-ion Battery

Jul 30, 2021 08:28 PM ET
  • CATL has actually exposed its first-gen Sodium-ion battery.
  • This battery would certainly be cost-efficient and also have a high rate of charging with a power density of 160Wh/kg.
  • The supply chain for these batteries is expected to develop in 2023.

Chinese battery giant, Contemporary Amperex Technology Ltd (CATL) has today disclosed the very first of its Sodium-ion battery.

At a launch event today, the battery manufacturer likewise introduced that it has intended to establish a supply chain for the new technology in 2023. Although the firm has not revealed the prices of the battery yet, the researchers have actually validated that this battery would certainly solve the expense difficulties.

Why Sodium-ion Battery?

As carbon nonpartisanship has actually ended up being a global concern and electrical lorries (EVs) have actually become progressively popular, need for crucial battery components, specifically cobalt, has increased. That has motivated car as well as battery makers to check out choices to the contemporary 3 main technologies-- nickel-cobalt-aluminum (NCA), nickel-cobalt-manganese (NCM), and lithium iron phosphate (LFP) batteries.

The r & d (R&D) rate of basic materials is increasing, which has opened a two-way window for the industrialization of sodium-ion batteries. The sodium-ion battery has a similar functioning concept to the lithium-ion battery, as well as the cost transfer is recognized mainly through the insertion and removal of sodium ions in between the favorable and unfavorable electrodes.

Just how is it?

According to the firm, the first-generation sodium-ion battery established by CATL has high power density, high price charging, exceptional thermal security, excellent low-temperature efficiency, and also high integration performance.

The power density of the battery cell is as high as 160Wh/kg, which is still less than lithium batteries. It can obtain charged at space temperature for 15 mins, and the power can reach greater than 80% in a low-temperature setting of -20 ° C. It also has a discharge retention rate of greater than 90%, system integration performance can reach 80 % Above, and the thermal stability much goes beyond the security requirements of the nation's standards.

This first-generation sodium-ion battery can not only be put on different EVs yet, additionally can be flexibly adapted to the application requirements in the power storage field.

Offering challenging competitors to its fellow companies like Japan's Panasonic Corp. and also South Korea's LG Chem, CATL has taken a new path in battery system integration and also established an AB battery system service. In the Abdominal Muscle battery system, sodium-ion battery as well as lithium-ion battery are combined as well as matched in a particular percentage, integrated into the very same battery system

According to Chairman, Mr. Zeng Yuqun, CATL has constructed a high-throughput product incorporated computing system to carry out simulation estimations as well as layout simulations on products at the atomic degree. The energy thickness R&D objective of the future generation sodium-ion battery is 200Wh/kg or even more. Although the company has not disclosed the costs of the battery yet, the scientists have validated that this battery would certainly fix the expense obstacles.
