Battery cell design 2.0
- What are changing in the end-user market and the pain points of the cell industry
- From a single cell or a handful of cells, typically used in consumer electronic devices, to a collection of cells with unit energy consumption at 1kWh and above
- An individual cell in a pack to electrify a system contains 10X or 100X more energy than that of 18650, and is much more economy in manufacturing and packing
- The heating and safety of big cells are as critical as their electrochemical functions to drive a system, and takes a big portion of the daily operation costs
- Cell manufacturing lags far behind the market demands, characteristic of high costs and slow paces in setting and scaling production line up with wild cell forms
- What unchanged is the demanding of high cost-performance ratio of cells
- DSTEM’s philosophy of Battery cell design 2.0
- DSTEM Cells are a structural and functional module of a pack to achieve 1 + 1 > 2 synergies in pack performance, durability, efficiency, and safety
- DSTEM Cells are designed on the end-user’s usage scenarios with high pack flexibility in the field
- DSTEM Cells and Packs are characteristic of collective energy-power balance and heat-cooling efficiency
- DSTEM Cells and Packs root on an innovative cell form, supporting all current and in-developing cell chemistry and cell physics in the market
- DSTEM technology supports Global resource and Local manufacturing at accelerate pace to handle the supply chain logistic challenging
- DSTEM technology supports Easy packing and Easy disassembly for recycling and throughout lifecycle management
How to improve the Tesla 4680-type cell performance and manufacturing
DSTEM shaft cell and pack architectures empower customers to use them in all-weather, all-terrain electrified power applications, ranging from data center power plants, mobile energy grids, to powertrain fleets across the sky, the sea, or the land, with high standard safety and reliability.
