GM will send batteries — new and old — to Redwood Materials, which will assemble them into large packs capable of supporting data centers and the grid.

Google's Pixel phones have grown from a curiosity to become some of the best smartphones you can buy, featuring excellent cameras and lengthy support. Unfortunately, they are also gaining a reputation for battery defects. For the second time in a year, Google has announced that it will render some of its past phones almost unusable with a software update, and users don't have any choice in the matter.

After nerfing the Pixel 4a's battery capacity earlier this year, Google has now confirmed a similar update is rolling out to the Pixel 6a. The new July Android update adds "battery management features" that will make the phone unusable. Given the risks involved, Google had no choice but to act, but it could choose to take better care of its customers and use better components in the first place. Sadly, a lot more phones are about to end up in the trash.

Bad batteries

Lithium-ion has become the technology of choice for rechargeable batteries due to its high energy density and reliability compared to other options. However, storing and releasing energy day after day causes inevitable wear and tear. Electrolytes that transport electrons can decompose into flammable gases and puff up your battery into a spicy little pillow, for example. Batteries also form clumps of lithium ions called dendrites, which grow and can cause internal shorts. This damage is accelerated by heat, and batteries get warmer the faster and longer they charge.

The president hasn't directly targeted the nascent industry, but his clean energy rollbacks could hurt it.

E-bike batteries are, for the most part, a collection of 18650 batteries, packaged together and welded in series and parallel, attached to a battery management system (BMS). A "dead" e-bike battery may only have two or three truly dead cells inside, while the remainder work fine. This is useful knowledge that, for the most part, very few e-bike owners can really use. Arc welders are not a common tool to own, and most e-bike batteries are not designed to be opened, safely or otherwise.

French firm Gouach, essentially a three-person company, is pitching its Infinite Battery as the opposite of this status quo. It's a durable, fireproof casing into which you can place and replace 18650 batteries using only a screwdriver. It keeps you updated on the status of cell performance and heat through a Bluetooth-connected app. And it's designed for compatibility with "90% of existing e-bike brands," or you can upgrade an existing "acoustic" model.

The money will fund a rapid expansion, including dozens more megawatt-hours of battery storage and plans for a domestic battery factory.
