China's CATL to develop new battery materials to improve energy density -chairman

China's CATL is working on new battery materials that can improve energy density by 10% to 20% compared to iron phosphate batteries, the company's chairman said, as the battery giant scrambles to retain its top position amid competition.

The new material technology known as M3P can enable an electric vehicle to run 700 km (430 miles) per charge combined with CATL's next generation of battery pack technology, Zeng Yuqun said at the World New Energy Vehicle Congress in Beijing on August 27, Reuters reports.

The new materials will also lower the costs compared to nickel and cobalt-based batteries, he added.

Zeng, however, didn't say what metals M3P batteries will use or when mass production could start.

CATL, whose clients include Tesla, Volkswagen, BMW and Ford is the world's biggest battery maker accounting for more than a third of the sales of batteries for electric vehicles (EV) worldwide.

It aims to increase the lead over rivals such as LG Energy Solution and BYD by accelerating expansions globally and innovation in new battery technologies.

Wan Gang, Vice Chairman of China's national advisory body for policymaking, said the global market size of EV batteries is expected to reach $250 billion by 2030, with demand exceeding 3.5 terrawatt hours.

CATL said in a separate announcement on Saturday that it will supply Qilin batteries with its latest battery pack technology to power Geely Automobile Holdings's Zeekr cars due to hit the market in early 2023.

CALT launched the Qilin battery in June and touted a 13% higher energy density compared to the same size of a pack of Tesla's 4680 cylindrical battery cells-- denoting 46 millimetres in diameter and 80 millimetres in length while using the same type of materials.
