| Given the current events, all these news need some CCP propaganda

| IMO the actually hard part is getting the tech to work the same

| hand-crafted battery pack that would actually show long range.
| I really hope they are successful, but until they can show
| manufacturing working I will keep my enthusiasm in check.

| How bout do both?

| This kind of announcements have been way too many. At this point

| lab, I don't care unless it's manufacturable in large quantities.
| There are plenty of amazing batteries that lack that quality.
|
| This all sounds a bit like last Hail Mary for some extra
| investment.
|
| That said, it would be really cool if the claims are true. I so
| _want_ this to be true. Just not holding my breath.

| For reference, they are claiming a specific energy of ~2000
| Wh/kg, whereas current Li-ion batteries are in the 200 Wh/kg
| range. At least according to Wikipedia, so far the highest
| demonstrated Li-S battery specific energy is 500 Wh/kg.
|
| They are also claiming a cost of $63/kWh vs $156/kWh for Li-ion
| today.

| That sounds suspiciously good.

| Yeah I'm expecting a caveat like "they explode if they reach
| 40 degrees C" or "they degrade by 20% after 20 recharge
| cycles."

| Personal fans that run all day. Tiles that keep working for

| bus routes. Electric airplanes make air travel significantly
| quieter and much cheaper. Internal combustion engines made
| obsolete and reduced to a historical curiosity. Electric
| scooters dominate worldwide as honda cubs become too expensive
| to fuel. I want it all.
| vardump wrote:
| Indeed, this high Specific Energy (~2000 Wh/kg) would be

|
| Heck, even high-altitude supersonic electric "jets", because
| you don't need oxygen to run electric motors!

| oh, so they dont exist yet, explains it
| api wrote:
| 1000 Wh/kg would be roughly 2X the best currently on the
| market, so that would be amazing if true.
| vardump wrote:
| More like 4x. Where can you get anything past about 250
| Wh/kg?

| Makes me wonder if this came to pass. Could an electric car be

|
| If the battery got small and you don't have the ice, could it
| be a problem? Would they add weights?

| Lithium sulfur batteries have a lot of potential and I really

| Or at least, they pan out in terms of 1% improvements and not
| 100% improvements like the breathless journalism claims.
