CATL is collaborating on the development of Condensed Battery for civilian electric aircrafts, and the battery for EVs will have mass production capability this year.
Chinese power battery giant CATL has unveiled its new battery technology, Condensed Battery, which is expected to be used in electric aircrafts and drive faster change in the electric vehicle industry.
CATL's Condensed Battery will feature high safety and high energy density, with single cells having an energy density of up to 500 Wh/kg, the company's chief scientist Wu Kai said today at the Shanghai auto show.
CATL has built a micron-scale adaptive mesh structure that regulates inter-chain interaction forces for changes in the electrochemical reactions of ultra-high energy density chemistries, according to Wu.
The battery also introduces a series of innovations in isolation films as well as innovative processes, including a high-energy cathode and a new type of anode, he said.
CATL is currently working on a collaborative development of a civilian electric aircraft project and is implementing aerospace-grade standards in the process to meet aerospace-grade safety and quality requirements, he said.
The Condensed Battery will also be available for use in electric vehicles and will have mass production capability within this year, Wu said.
CATL initially said at the Chongqing auto show in late June last year that the company was developing Condensed Battery, in addition to solid-state and semi-solid-state batteries.
On August 28, 2022, Wu said at a new energy vehicle industry conference that Condensed Battery has features including high safety, high reliability, and good cycle life.
As some background, 500 Wh/kg energy density is the highest we've seen to date for any power cell claimed to be able to be mass-produced.
Current mainstream lithium-ion battery cells have energy densities of just over 200 Wh/kg, and NIO's (NYSE: NIO) 150 kWh semi-solid-state battery, which is expected to be available in a few months, is 360 Wh/kg.
Higher energy density means greater R&D challenges and thus higher costs.
NIO's 150-kWh pack costs about as much as an ET5 sedan, the company's co-founder and president Qin Lihong said on February 11 at a face-to-face user event in Changzhou, Jiangsu province.

BYD (OTCMKTS: BYDDY) has started pre-sale for a mini electric vehicle that promises to be one of the vehicle choices for many families on short trips.
BYD unveiled the Seagull, the latest addition to its Ocean series, and started its pre-sales on the first day of the Shanghai auto show on April 18.
The vehicle is available in three versions with starting prices of RMB 78,800 ($11,460), 83,800 and 95,800 respectively.
It is worth noting that these are not the final prices of the model, and BYD's previous practice was to have final prices slightly lower than the pre-sale prices.
The BYD Seagull is an A0-class electric vehicle based on the e-Platform 3.0 with a length, width and height of 3,780 mm, 1,715 mm and 1,540 mm, respectively, and a wheelbase of 2,500 mm.
For comparison, the SAIC-GM-Wuling Binguo has a length, width and height of 3,950 mm, 1,708 mm and 1,580 mm, with a wheelbase of 2,560 mm. Its Hongguang Mini EV has a length, width and height of 2,920 mm, 1,493 mm and 1,621 mm, with a wheelbase of 1,940 mm.
The starting price of the Binguo is RMB 59,800 and the Honguo Mini EV starts at RMB 32,800.
The BYD Seagull is powered by a permanent magnet synchronous motor with a maximum power of 55 kW and peak torque of 135 Nm, accelerating from 0 to 50 km/h in 4.9 seconds.
The car is available in two range versions, with the lower-priced two models having a CLTC range of 305 km and the highest-priced version having a range of 405 km.
The BYD Seagull uses BYD's blade batteries with pack capacities of 30.08 kWh and 38.88 kWh respectively.
The car supports fast charging, taking 30 minutes to charge from 30 percent to 80 percent.
Previous rumors suggested that the model would have a version with sodium-ion batteries, but this does not appear to be a reality.
(1 $= RMB 6.8760)
