China's Potential Dominance in Battery Technology

China is leading the way in the development of sodium batteries, which are cheaper and more abundant than lithium batteries. Sodium batteries can be recharged daily for years and keep almost all of their charge in freezing temperatures. Chinese companies have figured out how to make sodium battery cells similar to lithium ones, and the world's largest electric car battery manufacturer, CATL, has discovered a way to use sodium and lithium cells in a single battery pack. Sodium batteries are expected to be used for electric grids and could replace lithium for certain applications.
