CATL plans to launch a second-generation Qilin Battery with a 6C charging multiplier in the second half of 2024, and BYD's second-generation Blade Battery could also be launched in the second half of the year, with a 6C battery in the works.

Gotion has launched the G-Current, which supports ultra-fast charging, the Stellary Battery, a large cylindrical battery, and announced the Gemstone, an all-solid-state battery.

CATL's energy storage battery business generated revenue of RMB 59.9 billion in 2023, contributing 14.94 percent of the total.

Talent said its solid-state battery cell prototype has an energy density of 720 Wh/kg, which is twice the energy density of Nio supplier WeLion's semi-solid-state battery cell.

The long-life battery will have 0 degradation in the first 1,000 cycles, Yutong said.

CATL is working with Tesla on battery technologies, particularly new electrochemical structures for faster charging, the Chinese battery maker's chairman said.

The new 75-kWh battery pack will not use both LFP cells and ternary cells like its predecessor and will begin deliveries soon with the 2024 models.

The battery pack, called "Wuling Red 1", is 148 mm thick, which SAIC-GM-Wuling said is the thinnest battery for commercial vehicles.

After 1,044 kilometers of driving, the Nio ET7 has a remaining charge of 3 percent or 36 kilometers of remaining CLTC range.

Zeekr said its Golden Battery is the world's first mass-produced 800 V LFP ultra-fast-charging battery with 83.7 percent volume utilization and a maximum charging power of 500 kW.
